The Battle of Sedan or Second Battle of Sedan (12–15 May 1940) [10] [13] [14] took place in the Second World War during the Battle of France in 1940. It was part of the German Wehrmacht 's operational plan codenamed Fall Gelb (Case Yellow) for an offensive through the hilly and forested Ardennes, to encircle the Allied armies in Belgium and north-eastern France. German Army Group A crossed the Meuse river with the intention of capturing Sedan and pushing northwards towards the Channel coast, to trap the Allied forces that were advancing east into Belgium, as part of the Allied Dyle Plan.

Battle of France Successful German invasion of France in 1940

The Battle of France, also known as the Fall of France, was the German invasion of France and the Low Countries during the Second World War. France had previously invaded Germany in 1939. In the six weeks from 10 May 1940, German forces defeated Allied forces by mobile operations and conquered France, Belgium, Luxembourg and the Netherlands, bringing land operations on the Western Front to an end until the Normandy landings on 6 June 1944. Italy entered the war on 10 June 1940 and invaded France over the Alps.

Wehrmacht unified armed forces of Germany from 1935 to 1945

The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe. The designation "Wehrmacht" replaced the previously used term Reichswehr, and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.

Manstein Plan

The Manstein Plan is one of the names used to describe the war plan of the German Army during the Battle of France in 1940. The original invasion plan was a compromise devised by General Franz Halder, the chief of the Oberkommando des Heeres staff and satisfied no one. Documents with details of the plan fell into Belgian hands during the Mechelen incident of 10 January 1940 and the plan was revised several times, each giving more emphasis to an attack by Army Group A through the Ardennes, which progressively reduced the offensive by Army Group B through the Low Countries to a diversion.

Sedan is situated on the east bank of the Meuse River. Its capture would give the Germans a base from which to take the Meuse bridges and cross the river. The German divisions could then advance across the open and undefended French countryside to the English Channel. On 12 May, Sedan was captured without resistance and the Germans defeated the French defences around Sedan on the west bank of the Meuse. Luftwaffe bombing and low morale prevented the French defenders from destroying the bridgeheads. The Germans captured the Meuse bridges at Sedan allowing them to pour forces across the river. On 14 May, the Allied air forces, the Royal Air Force (RAF) and Armée de l'Air (French Air Force) tried to destroy the bridges. The Luftwaffe prevented them from doing so. In large air battles, the Allies suffered high losses which depleted Allied bomber strength in the campaign. [15]

<i>Luftwaffe</i> Aerial warfare branch of the German military forces during World War II

The Luftwaffe was the aerial warfare branch of the combined German Wehrmacht military forces during World War II. Germany's military air arms during World War I, the Luftstreitkräfte of the Army and the Marine-Fliegerabteilung of the Navy had been disbanded in May 1920 as a result of the terms of the Treaty of Versailles which stated that Germany was forbidden to have any air force.

Royal Air Force Aerial warfare service branch of the British Armed Forces

The Royal Air Force (RAF) is the United Kingdom's aerial warfare force. Formed towards the end of the First World War on 1 April 1918, it is the oldest independent air force in the world. Following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain.

The French counter-attacked the German bridgeheads from 15 to 17 May, but the offensives fell victim to delay and confusion. On 20 May, five days after consolidating their bridgeheads, the German Army reached the Channel. Crossing the Meuse had enabled the Germans to achieved the operational goal of Fall Gelb and encircle the strongest Allied armies, including the British Expeditionary Force. The resulting June battles destroyed the remaining French army as an effective fighting force and expelled the British from the continent, leading to the defeat of France. [15] [16]

British Expeditionary Force (World War II) British Army in Western Europe from 1939 to 1940

The British Expeditionary Force (BEF) was the name of the British Army in Western Europe during the Second World War from 2 September 1939 when the BEF GHQ was formed until 31 May 1940, when GHQ closed down. Military forces in Britain were under Home Forces command. During the 1930s, the British government planned to deter war by rearming from the very low level of readiness of the early 30s and abolished the Ten Year Rule. The bulk of the extra money went to the Royal Navy and the Royal Air Force but plans were made to re-equip a small number of Army and Territorial Army divisions for service overseas.

Background

German plan

On 10 May 1940, the Wehrmacht invaded Luxembourg, Netherlands and Belgium. In the Netherlands the Germans made steady progress. By 12 May, units of the German Army Group B were closing on Rotterdam and Amsterdam, while in central Belgium the Germans were close to reaching the Dyle river east of Brussels. [17] In response to the invasions, the Allied First Army Group, under the command of Gaston Billotte, containing the French Seventh Army, French Ninth Army, French First Army and the British Expeditionary Force, advanced to the Dyle river in order to form a solid front line as part of the Dyle Plan, a defensive strategy to halt the German advances in Belgium. However, the offensive by Army Group B was a diversion. The main thrust of Fall Gelb was to be conducted by Army Group A through the Ardennes in Luxembourg and southern Belgium. Once these lightly defended areas were negotiated, Army Group A's XIX. Panzerkorps (19th Tank Corps), under the command of Heinz Guderian, was to strike into France at Sedan, located on the Meuse river. Its capture would enable a German advance into the undefended depths of France and to the English Channel, into the rear of the Allied mobile forces advancing into Belgium. The result would be a strategic-level encirclement. [18]

Luxembourg Grand duchy in western Europe

Luxembourg, officially the Grand Duchy of Luxembourg, is a small landlocked country in western Europe. It is bordered by Belgium to the west and north, Germany to the east, and France to the south. Its capital, Luxembourg City, is one of the four official capitals of the European Union and the seat of the European Court of Justice, the highest judicial authority in the EU. Its culture, people, and languages are highly intertwined with its neighbours, making it essentially a mixture of French and German cultures, as evident by the nation's three official languages: French, German, and the national language of Luxembourgish. The repeated invasions by Germany, especially in World War II, resulted in the country's strong will for mediation between France and Germany and, among other things, led to the foundation of the European Union.

Battle of the Netherlands Nazi invasion of the Netherlands

The Battle of the Netherlands was a military campaign part of Case Yellow, the German invasion of the Low Countries and France during World War II. The battle lasted from 10 May 1940 until the surrender of the main Dutch forces on 14 May. Dutch troops in the province of Zeeland continued to resist the Wehrmacht until 17 May when Germany completed its occupation of the whole country.

Battle of Belgium battle

The Battle of Belgium or Belgian Campaign, often referred to within Belgium as the 18 Days' Campaign, formed part of the greater Battle of France, an offensive campaign by Germany during the Second World War. It took place over 18 days in May 1940 and ended with the German occupation of Belgium following the surrender of the Belgian Army.

For the offensive, the Oberkommando der Wehrmacht (German High Command) gave Army Group A the most powerful concentration of German armour and motorised forces. Although Army Group B was allocated 808 tanks, over 14 of the total German tanks, they were largely light tanks such as the Panzer I and Panzer II, as opposed to the Panzer III and Panzer IV. The heavier tanks were handed over to Army Group A as it required the best machines to conduct the critical operation at Sedan. [19] Army Group A contained 1,753 tanks of the heavier types. [8]

<i>Oberkommando der Wehrmacht</i> High Command of the Wehrmacht (armed forces) of Nazi Germany during World War II

The Oberkommando der Wehrmacht was the High Command of the Wehrmacht of Nazi Germany during World War II. Created in 1938, the OKW had nominal oversight over the Heer (Army), the Kriegsmarine (Navy), and the Luftwaffe.

Light tank class of tanks of relatively light weight

A light tank is a tank variant initially designed for rapid movement to quickly move in and out of combat, and outmaneuver heavy main battle tanks. They are primarily employed in the screening and reconnaissance role or in a fire support role of expeditionary forces where big main battle tanks cannot be made available or can't operate safely. Early light tanks were generally better armed and armored than armored car, but used tracks in order to provide better cross-country mobility.

Panzer I 1934 German light tank family

The Panzer I was a light tank produced in Germany in the 1930s. The name is short for the German Panzerkampfwagen I, abbreviated PzKpfw I. The tank's official German ordnance inventory designation was Sd.Kfz. 101.

'Impenetrable' Ardennes

Following the First World War, the French General Staff had ruled out the idea of a future German thrust through the Ardennes–Sedan sector. The French were certain such terrain could not be crossed by tanks. Marshal Philippe Pétain described them as "impenetrable". [20] Maurice Gamelin described the geographical feature as "Europe's best tank obstacle". [20] The "barrier" of the Meuse and Ardennes appeared to be a sound strategic defence feature that a future enemy could not get through or go around. [20] The French concluded that at best, a German assault through the Ardennes towards Sedan would not reach the Meuse until two weeks after the start of any German offensive, taking between five and nine days to penetrate the Ardennes alone. [21]

Philippe Pétain French military and political leader

Henri Philippe Benoni Omer Joseph Pétain, generally known as Philippe Pétain, Marshal Pétain or The Old Marshal, was a French general officer who attained the position of Marshal of France at the end of World War I, during which he became known as The Lion of Verdun, and in World War II served as the Chief of State of Vichy France from 1940 to 1944. Pétain, who was 84 years old in 1940, ranks as France's oldest head of state.

Maurice Gamelin French general

Maurice Gustave Gamelin was a French army general in the French Army. Gamelin is remembered for his disastrous command of the French military during the Battle of France in World War II and his steadfast defence of republican values.

The French assessments were less credible in the light of military exercises carried out in 1938. That year, General André-Gaston Prételat took command of manoeuvres which created a scenario whereby the German Army launched an assault with seven divisions, including four motorised infantry divisions and two tank brigades (the type of the remaining three are not given). [22] The "French" side's defences collapsed. "The result was a defeat of so comprehensive a nature that the wisdom of publishing it was questioned lest morale be damaged." [22] As late as March 1940, a French report to Gamelin named the defences at Sedan, the last "fortified" position on the Meuse, and the last before the open country of France, as "entirely inadequate." [22] Prételat had correctly identified the landscape as relatively easy terrain for armour to cross. At most, he concluded, the Germans would take 60 hours to reach the Meuse and take one day to cross it. [23] This estimate was to prove only three hours too late. The Germans achieved the Meuse crossing after just 57 hours. [23]

The French Army authorised fresh attempts to increase the strength of the fortifications in the autumn of 1939, but severe winter weather prevented the pouring of concrete and the delivery of the necessary materials. [22] On 11 April 1940, General Charles Huntziger asked for another four divisions to work on the defences but was refused. [24]

French defences at Sedan

The French defences at Sedan were weak and neglected. [25] The French had long believed that the German Army would not attack through the Sedan sector as part of their concentrated effort, and only Brigadier General Pierre Lafontaine's French 55th Infantry Division, a category B division, was allocated to this sector. The Maginot Line ended 20 kilometres (12 mi) east of Sedan at La Ferté, where Fort No. 505 constituted its most westerly position. Sedan was a part of the extended Maginot Line that ran north behind the Meuse river. Between Sedan and La Ferté lay the Stenay gap, which was a stretch of unprotected terrain not covered by French defences or natural obstacles. This was the reason a significant number of French generals insisted on strengthening this sector, while ignoring Sedan. [25]

As the French constructed further fortifications, Luftwaffe reconnaissance aircraft picked up the activity and reported it. The steep slopes on the banks of the Meuse, added to what appeared in photographic reconnaissance to be a formidable barrier of bunkers and defence lines, caused Field Marshal Gerd von Rundstedt, the commander in chief of Army Group A, to question the wisdom of Guderian in choosing Sedan as the point of maximum effort. [25] To identify how strong these fortifications were, a team of photographic specialists were called in to evaluate the pictures. Their analysis concluded that what appeared to be strong fortified positions were just the construction sites of half-built bunkers that were, to all intents and purposes, empty shells. The contribution of the specialists tilted the Sedan attack plan into Guderian's favour. [25]

General Huntziger was happy to rely on "concrete" to ensure the safety of Sedan as he rejected the idea that the Germans would attack through the Ardennes. The Second Army built 52,000 cubic metres (1,800,000 cu ft) of concrete fortifications along its front, but very little in the Sedan sector. Only 42 bunkers protected the Sedan bridgeheads on the outbreak of war in September 1939 and an additional 61 were built by 10 May. However, by 10 May, most of the bunkers were incomplete, lacking gun port shutters for the artillery casemates. Some of the bunkers lacked rear doors, making them vulnerable to infiltration by infantry. [26] To the north of Sedan, on the northern bend of the Meuse, the town of Glaire overlooked the crossing points on the river, which was to be where the German armour would deliver its heaviest blow. There was a gap of 2 kilometres (1.2 mi) between Bunker 305 at Glaire and Bunker 211 next to the Pont Neuf bridge. This allowed an attacker coming from the north to use the good road routes through the FleigneuxSaint-Menges–Glaire axis to enter Sedan from the north. [27]

The defences at Sedan also lacked any mines. The French Second Army was guarding a front of 70 kilometres (43 mi), and was given only 16,000 mines. Of that number, 7,000 were given to the cavalry divisions that were intended to delay a German advance through southern Belgium as well as to blockhouse points along the Franco–Belgian border. That left 2,000 for the defence of the river Meuse. Of those, the 55th Infantry Division got 422. Not all of these were laid, and some barriers were moved during the bunker construction in the Sedan sector. [28]

German approach

As the German Army advanced through southern Belgium on 12 May, General Ewald von Kleist and Guderian clashed over where the main point of effort should fall. Kleist was Guderian's immediate superior, commanding Panzergruppe von Kleist, consisting of XLI Panzer Corps and XIX Panzer Corps (under Guderian). [29] [30] Kleist pressed for the main point to come at Flize, further west than Sedan. Kleist argued that the blow would avoid a double river crossing at the Meuse (at Sedan) and Ardennes canal (to the west of Sedan). Moreover, the blow would strike at the dividing line between the French Ninth Army and the French Second Army. Guderian saw things differently, and pointed out that a thrust along the lines of Kleist's plan would put the flank of the advance within range of the fortress artillery at Charleville-Mézières, some 25 kilometres (16 mi) north west of Sedan. The shift of operations further north would also disperse concentration (or Schwerpunkt ) and disrupt the intense planning of the German tactical units, who had been in training for the Sedan attack and an advance north-west, for months. He also felt that a regrouping period in front of Sedan would delay the assault for 24 hours and allow the French to bring up reinforcements. Kleist agreed that such a delay was unacceptable, so he agreed to Guderian's plan. [18]

Nevertheless, while Kleist accepted the folly of the Flize detour, he insisted the offensive concentration point should be made west of the Ardennes Canal. Kleist reaffirmed this in a letter to Guderian on 18 April, but when operations began Guderian ignored this completely. Guderian had wanted a large, 20-kilometre (12 mi) bridgehead at Sedan and the rapid occupation of Stonne and the high ground surrounding Sedan. [31]

Guderian's plan for 13 May was straightforward. The 2nd Panzer Division in the north was to form the right flank of the assaulting force when it reached the Meuse near Donchery. The 1st Panzer Division, reinforced by the Infantry Regiment Großdeutschland , a battalion of assault engineers, and divisional artillery of the 2nd and 10th Panzer Divisions, was to make the main attack by crossing the Meuse just north of Sedan and seizing the Heights of la Marfee overlooking the city. The 10th Panzer Division was to cross the Meuse south of Sedan and protect the southern flank of the corps. Throughout the day, large masses of troops and equipment assembled north of the Meuse in preparation for the river crossing. [32]

Forces involved

German forces

The German forces consisted of the 1st, 2nd and 10th Panzer Divisions. The 1st Panzer Division under the command of General-Major (Major General) Friedrich Kirchner, had on strength 52 Panzer IIs, 98 Panzer III, 58 Panzer IV, 40 Panzer 35(t) and eight Sd.Kfz. 265 Panzerbefehlswagens. [8] The 2nd Panzer Division, under the command of Generalleutnant (Lieutenant General) Rudolf Veiel, had to hand 45 Panzer I, 115 Panzer II, 59 Panzer III and 32 Panzer IVs. [8] It also had 16 Sd.Kfz. 265. [8] The 10th Panzer Division, under the command of Generalleutnant Ferdinand Schaal, had 44 Panzer I, 113 Panzer II, 58 Panzer III, 32 Panzer IV and 18 Sd.Kfz. 265. [8] In total Guderian could muster 60,000 men, 22,000 vehicles, 771 tanks and 141 artillery pieces. [8] He could also call upon 1,470 aircraft. [3]

Part of Guderian's problem was the lack of mobile artillery. He had no intention of halting the breakout in order to wait for additional artillery units to be moved into place to assault Sedan. Instead, Guderian requested maximum support from the Luftwaffe. For the first few days the German air arm would be used mostly in support of Army Group B. [33] Most of the air support over Sedan was to be provided by Luftflotte 3 (Air Fleet 3). Initially, only limited numbers of air units were to be used, but the Luftwaffe's workload was greatly increased nearer the time of the battle. [33] The Luftwaffe was to commit I. Fliegerkorps (1st Air Corps under Ulrich Grauert), II. Fliegerkorps (under Bruno Loerzer), V. Fliegerkorps (under Robert Ritter von Greim), and VIII. Fliegerkorps (under Wolfram Freiherr von Richthofen). These units came from Luftflotte 2 and Jagdfliegerführer 3 (Fighter Leader 3). [3] The most significant unit was VIII. Fliegerkorps, nicknamed the Nahkampf-Fliegerkorps (Close Support Air Corps), which contained Sturzkampfgeschwader 77 (Dive bomber Wing 77), a powerful concentration of dive-bomber units equipped with the Junkers Ju 87 Stuka precision ground attack aircraft. [3] This powerful air concentration numbered some 1,470 aircraft; 600 Heinkel He 111 and Junkers Ju 88 medium bombers and Dornier Do 17 light bombers, 250 Ju 87s, 500 Messerschmitt Bf 109s and 120 Messerschmitt Bf 110s. [3]

French forces

In the sector of Longwy, Sedan and Namur, where the Ardennes and the River Meuse meet, the French Ninth Army and French Second Army were made up chiefly of poor quality divisions. Reinforcements were minimal, and those units were equipped with obsolete weapons. The resources at the disposal of the two Series B divisions, the 55th and later 71s Infantry Divisions, who were to bear the brunt of the attack, were weak. They had almost no Regular officers and they had not been broken-in to war conditions by being in contact with the enemy. [34]

The 55th Infantry Division guarding Sedan had little time for combat training, as its time had been spent in construction work. The division consisted mainly of reservists, most of who were over the age of 30. Little attempt was made to improve the poor combat quality of the division. One officer, First Lieutenant Delas of the 1st Battalion 147th Fortress Infantry Regiment was arrested and confined for 15 days for ordering firing practice with a 25mm anti-tank gun in a nearby quarry. [35] The division's commanding officer, General Lafontaine, put more faith into fortifications than training, as he believed it would compensate for the weakness of the division. The men of the division lacked the confidence and will to fight when the battle took place. [35]

The organisation of the French 55th Infantry Division was chaotic. Most units had been involved in construction work and were constantly moved to different tactical positions. Of the nine companies in position by 10 May, only a few had been holding their respective positions for even a few days and were not familiar with them. One of the premier infantry regiments, the 213th Infantry Regiment, was removed from the line altogether and was replaced with the 331st Regiment. In some cases, Infantry regiments were made up of several different companies from several different battalions from different regiments. For example, the 295th Infantry Regiment's 6th Company, 2nd Battalion, was made up of four different companies which were drawn from three different battalions belonging to three different regiments. [36]

Such actions damaged the cohesion of the units that were initially strong. The 147th Fortress Regiment was the backbone of the 55th Infantry Division and was to occupy the bunker positions on the Meuse. At the start of mobilisation, the unit had high morale and very good cohesion. Because of the constant changes in organisation, however, the unit's battalions were "torn apart again and again". [37]

To relieve the 55th Infantry Division, the French 71st Infantry Division was ordered out of reserve and into the frontline. The presence of the 71st Infantry shortened the front from 20 to 14 kilometres (12.4 to 8.7 mi) along the Meuse. This would increase the density of fighting strength in the immediate area, but such a move was only partially complete by 10 May, as it was scheduled to be completed on 13–14 May, three days after the German attack. [38] Although the two divisions had 174 artillery pieces, more than the German forces opposing them, they had to share that force between them. Both divisions were short of anti-tank and anti-aircraft guns, a critical short-coming. [39]

Crossing the Meuse

Capture of Sedan

The main problem confronting Guderian and his Sedan method was inadequate artillery support. Several batteries were stuck in traffic in the Ardennes and he could not rely on the artillery batteries of his Panzer Divisions only. Everything depended on the support of the Luftwaffe. General der Flieger Hugo Sperrle, commander of Luftflotte 3, had planned a conventional method of a brief bombardment before the ground forces moved in. After preparatory raids, the medium and dive-bombers were to smash the French defences in a concentrated blow lasting 20 minutes. The raid was planned for 16:00 before the infantry crossed the Meuse. In collaboration, Bruno Loerzer's II. Fliegerkorps had developed the concept of the rolling raid with Guderian. The idea of a single massed strike was abandoned, and the German air units were to attack in small formations but constantly, through the day. It was deemed the effect would be threefold; the French artillery would be eliminated, the effect of continuous raids would damage enemy morale, and smaller formations would be more systematic and accurate against targets such as bunkers. [40]

Unknown to Guderian, von Kleist, his immediate superior, had contacted Loerzer and banned Guderian's proposed long systematic approach in favour of one big assault. Guderian complained. Kleist ignored him. Yet, the following morning, Loerzer rejected Kleist's method and went ahead with the agreed rolling bombing as discussed with Guderian. Loerzer would later say that the official order from Hugo Sperrle had arrived too late to make changes. [41]

By nightfall on 12 May, Guderian's XIX. Panzerkorps rolled into Sedan. Guderian reported there was no sign of the enemy. [42] With the city itself secured, Guderian would now have to strike south, across the defended rear behind Sedan, which in turn was protected by a large bunker complex located on Marfee ridge, a piece of high ground covering the Sedan-Meuse river to the south. But there were three fundamental choices. He could obey tactical necessity and protect the bridgeheads against a French counter-attack from the south; he could strike west towards Paris with his Corps; or he could carry out the dash to the Channel. Remembering the Chief of Operations, 1st Panzer Division, Walther Wenck's saying, "Hit with your fists, don't feel with your fingers!", Guderian decided on the last option. [43]

In the early hours of 13 May, the 10th Panzer Division slipped into position upstream to the north-east of Sedan, ready to strike at its designated crossing point near the town of Wadelincourt. Downstream, the 2nd Panzer Division moved into position to cross at Donchery. The 1st Panzer Division prepared to strike at the Gaulier bridgehead, near Floing, in the centre of Sedan's tactical front. It was on the northern bend of the Sedan Meuse loop that the Luftwaffe was to make its maximum effort, between Gaulier and Wadelincourt. To supplement his air support, Guderian stripped most of his Panzer Divisions of their artillery, which he then positioned directly opposite Gaulier. [33] However, the artillery regiments lacked ammunition. Sustained and damaging bombardment through shelling was impossible. The Luftwaffe was going to have to do most of the work. [33] Guderian reported that his Corps had only 141 artillery pieces against the French 174. [6] To the north and south of Sedan, the French X Corps and French XXXXI Corps (at the artillery fortress at Charleville-Mézières) could also add their artillery and shell Guderian's Panzer units as they crossed the bridgeheads. [6] The slow advance of artillery units to the front added to the German numerical inferiority, which was now 1:3 against. [6] Only in the afternoon did the German artillery make an appearance, but with little effect. The 2nd Panzer Division was forced to attack without artillery support. For these reasons, Guderian had decided the outcome depended on the quality of air support, acting as flying artillery. [6]

Luftwaffe assault

Luftflotte 3 (commanded by Hugo Sperrle), supported by Luftflotte 2 (commanded by Albert Kesselring), executed the heaviest air bombardment the world had yet witnessed and the most intense by the Luftwaffe during the war. [44] The Luftwaffe committed two Sturzkampfgeschwader (dive bomber wings) to the assault, flying 300 sorties against French positions, with Sturzkampfgeschwader 77 alone flying 201 individual missions. [45] A total of 3,940 sorties were flown by nine Kampfgeschwader (Bomber Wing) units often in Gruppe strength. [46]

The planned aerial assault would last for eight hours, from 08:00-16:00. [47] Loerzer and Richthofen committed two Stuka units to the attack. Loerzer's Ju 87s flew some 180 missions against Sedan's bunkers whilst Richthofen's managed 90. The nine Kampfgruppen (bomber wings) of Bruno Loerzer's II. Fliegerkorps flew 900 missions against the 360 of Wolfram Freiherr von Richthofen's VIII. Fliegerkorps. VIII. Fliegerkorps's total mission count on the Meuse front was 910 compared to II. Fliegerkorps 1,770 missions. [48]

The Luftwaffe's target was the Marfee heights which lay behind Sedan to the south east. They contained the fortified artillery positions and dominated the approaches to the strategic and operational depths beyond Sedan and the Meuse. [41] The Luftwaffe was two hours late in appearing but the effort made was considerable. The attacks were made in Gruppe (group) strength and against the line of maximum resistance along the enemy gun line. To restrict enemy movements and communications, German fighters swept the area to cut land-lines and strafe fortifications, with some shooting of radio antennae off command posts. The attacks isolated the forward defence lines. [46] Sturzkampfgeschwader 77 struck first in the morning of 13 May. In just five hours, 500 Ju 87 sorties had been flown. [49]

The Luftwaffe cowed the defenders, breaking them psychologically. The gunners, the backbone of the defences, had abandoned their positions by the time the German ground assault had begun. The cost to the Luftwaffe was just six aircraft, three of which were Ju 87s. [46]

The French 55th Infantry Division was not prepared for such an attack. French soldiers had commented on the massive psychological effect of the bombardment, in particular the siren of the Ju 87. However, after the war, it was discovered that none of the bunkers had been destroyed by direct hits. [50] Moreover, just 56 French casualties were suffered. [50] It was the indirect effect that did the damage. The telecommunication cables were destroyed (most had been laid out in the open) through bombing, paralysing the division's communications, and the psychological damage crippled its defensive capacity. [50]

The ensuing psychological damage contributed to "the panic of Bulson". At about 19:00 on 13 May, a report by a French artillery observer was passed on incorrectly. There was a rumour that German tanks were approaching the town of Bulson. The false reports spread and the French 55th Infantry Division deserted their positions. German sources say that the first German tank crossed the Meuse River 12 hours later. [51] By the time the error was realised, most of the artillerymen and infantrymen had abandoned their heavy equipment. [52]

1st Panzer at Gaulier

German advance by 14 May 1940.

The central ground assault was to be conducted by the 1st Panzer Division and supported by the Infantry Regiment Großdeutschland and the Sturmpionier-Battalion 43 (43rd Assault Engineer Battalion) as the 1st Panzer only had a single rifle regiment. [50] The Großdeutschland would be attached to the 1st Panzer Division for the remainder of the campaign [53] and it was the first unit to breach the defences on Hill 247, the high ground dominating Gaulier. The regiment, much to their surprise, discovered the Luftwaffe had failed to destroy the enemy bunkers. Enemy small arms fire ensured that crossing the river at Pont Neuf bridge could not be done in rubber assault boats as intended. The Regiment retreated. Reconnaissance found an enemy Bunker, No. 211, was still active. Its location guarded the bridgehead, making it dangerous for German infantry attempting a crossing. A platoon of infantry guns (75 mm short barrel artillery) failed to knock it out. An 8.8 cm FlaK dual purpose gun (88 mm) was brought in to do the job. It succeeded, but the following crossing failed as machine gun fire came from another flanking position that had not been spotted. Once this was dealt with by the 2nd Battalion, the remainder of the regiment crossed the river. [50] Throughout the rest of the day, the regiment moved up and into the French defences, the 2nd Battalion's 6th, 7th and 8th Companies gradually knocking out each bunker. Despite the other two battalions being held up further south, by 20:00 the central Hill 247 had been taken. [54] The Großdeutschland Regiment had now penetrated 8 kilometres (5.0 mi) into the French defences. [53]

On Hill 301, further west, the First Rifle Regiment under Col. Hermann Balck had helped take the position by nightfall. With help from two platoons of the 3rd Company of the 34th Assault Engineer Battalion, it had succeeded in knocking out the bunker positions. The regiment inched westward and was able to see the 2nd Panzer Division on the extreme west flank of the 1st Panzer, attacking the bunker position near Donchery. Several Panzers were knocked out. The First Rifle Regiment, 1st Panzer, had crossed the boundary into the 2nd Panzer's territory. They eased the 2nd Panzer's passage by knocking out several bunkers on their eastern flank and succeeded in cutting the Donchery-Sedan road. The infantry also succeeded in knocking out most of the casemates in the area using flamethrower teams to destroy the bunkers whose infantry failed to surrender quickly. [55] The last bunker to surrender did so at 22:40 hours on 13 May. By that time, elements of the 1st and 2nd Panzer Divisions had negotiated the Meuse river. [55]

2nd Panzer at Donchery

The 2nd Panzer had been given the most difficult job. Its advance through the Ardennes trapped and delayed it in nearly 250 kilometres (160 mi) of traffic. Consequently, it arrived late at Donchery, after the 1st and 10th Panzer Divisions had initiated their assaults across the Meuse. Due to a combination of its being late and the attacks of its sister units, the enemy defences were alerted in advance of the 2nd Panzer's offensive. Crossing at the extreme western end of the Sedan sector on the Donchery axis, it was forced to advance across open terrain for the last 3 km before reaching the bridgehead. This subjected the division to fire from Donchery and the Bellevue Castle's 75mm artillery casemates, located slightly to the east of the town. Several boats were tied to the Panzers and dragged across, but the tanks were knocked out. [56] The bulk of the 174 artillery pieces available to the French at Sedan were concentrated on the 2nd Panzer Division's front. Most were located in the bunkers on the south side of the river Meuse-Donchery sector. Some of the French 102nd Infantry division's batteries also joined in from the north west, at Charleville. The only way to respond was with howitzers but the 2nd Panzer Division had handed its heavy howitzers over to the 1st Panzer. Only 24 guns remained and they did not arrive on the battlefield until 17:00. When they arrived, they had only had a couple of shells per gun owing to the logistical tailback in the Ardennes. [57]

All attempts to land on the southern side of the Meuse failed. Fortunately for Guderian, the 1st Panzer Division succeeded in crossing the Meuse in the centre (see above). Once completed, it headed into the right (eastern) flank of the French at Donchery. Some of its units cleared the Meuse bend. Assault Engineers and 1st Panzer Division neutralised the guns at Bellevue Castle, and cleared the bunker positions along the Meuse River from the rear. The artillery falling on the 2nd Panzer Division's eastern flank was stopped. [57] With the threat of artillery fire on its right flank removed, the units on the 2nd Panzer's left flank crossed the river and infiltrated the French positions opposite Donchery at 20:00. Heavy French fire continued from the bunkers in front of Donchery on the south side of the Meuse. It was not until 22:20, in darkness, that regular ferrying missions enabled the reinforcement of the German bridgehead. [57]

10th Panzer at Wadelincourt

The 10th Panzer Division, like the 2nd Panzer Division, had detached its heavy artillery batteries to support neighbouring units. It was left with just 24 light 105 mm howitzers. [12] Moreover, the batteries were short of ammunition. The Luftwaffe had not helped the 10th Panzer Division as most of the air attacks were in support of the 1st Panzer Division in the central sector. This meant all of the French artillery and machine gun positions in the area of Wadelincourt were undisturbed. [12] Added to this, the newly inserted 71st Infantry Division and French X Corps in the Rémilly area prevented the 10th Panzer Division making any quick progress. The Division also had to advance down to the river on open flat terrain of some 600–800 metres (2,000–2,600 ft). [12]

Near the town of Bazeilles, the Engineers and assault infantry had gathered to prepare the boats for the crossing of the Meuse at Wadelincourt when an artillery barrage from the French positions destroyed 81 out of 96 rubber boats. [12] The plan of attack had included an assault by both the 69th and 89th Infantry Regiments, but the loss of so many boats meant that only the 86th Infantry Regiment was able to conduct the crossing. The 69th Infantry Regiment was kept in reserve to follow the 86th as reinforcements. [12]

The 10th Panzer Division's assaults failed all along the Meuse front. The only success came from a small 11-man team (five engineers and six infantrymen) of the 2nd Company, Panzerpionier-Batailion 49 (49th Panzer Engineer Battalion) placed under the 1st Battalion, 86th Infantry Regiment. Unsupported and acting on their own initiative, this small force led by Feldwebel Walter Rubarth opened a decisive breach by knocking out seven bunker positions. Follow-up units from the 1st Battalion 86th Rifle Regiment had crossed over by 21:00 and stormed the remaining bunkers on Hill 246, where the main French defence positions were located. By the end of the day, the bridgehead had been consolidated and the objective taken. [58]

Allied air strikes

The RAF Fairey Battle suffered heavy losses over the bridgehead

In the central sector, at Gaulier, the Germans began moving 3.7 cm Pak 36 light infantry field artillery across the Meuse to provide support to infantry across the river. By 01:00 on 14 May, a pontoon bridge had been erected over which Sd.Kfz. 222, Sd.Kfz. 232 and Sd.Kfz. 264 armoured cars began to dismount in the bridgeheads. French reports spoke of German tanks crossing the bridges. Such reports were in error, as the first Panzers only crossed at 07:20 on 14 May. Prior to this masses of lorries, armoured cars and other traffic had passed through but not tanks. [53]

The capture of Sedan and the expansion of the bridgeheads alarmed the French who called for a total effort against the bridgeheads at Sedan, to isolate the three Panzer Divisions. General Gaston-Henri Billotte, commander of the First French Army Group, whose right flank pivoted on Sedan, urged that the bridges across the Meuse be destroyed by air attack, convinced that "over them will pass either victory or defeat!". [46] [53] General Marcel Têtu, commander of the Allied Tactical Air Forces ordered: "Concentrate everything on Sedan. Priority between Sedan and Houx is at 1,000,000 to 1". [4]

No. 103 Squadron and No. 150 Squadron RAF of the RAF Advanced Air Striking Force (AASF) flew 10 sorties against the targets in the early morning. In the process they suffered only one loss in a forced landing. Between 15:00–16:00, 71 RAF bombers took off escorted by Allied fighters. The impressive escort was offset by the presence of German fighter units that outnumbered the Allied escort fighters by 3:1. [59] No. 71 Wing RAF lost 10 Fairey Battles and five Bristol Blenheims. No. 75 Wing RAF lost 14–18 Battles and No. 76 Wing RAF lost 11 Battles. [59] Out of 71 bombers dispatched, 40–44 bombers were lost, meaning a loss rate of 56–62 percent. [59] The AASF lost a further five Hawker Hurricanes. [59] The AASF flew 81 sorties and lost 52 percent of its strength. No 2 Group RAF also contributed with 28 sorties. [60] The bombing results were poor, with three bridges damaged and one possibly destroyed. [59]

French Air Forces under the command of Commandant des Forces (Commander of Forces) Marcel Têtu Aeriennes de Cooperation du Front Nord-Est (Ardennes Cooperation Front North East, or FACNE) [61] rarely supported the British efforts despite substantial reinforcements. They flew only an average of one sortie per day, including strategic defensive missions. [62] One reason for this was heavy French bomber losses on the previous two days. During the Battle of Maastricht in the Netherlands, the Groupement de Bombardement (Bomber Groups, or GB) had its squadrons reduced. GB I/12 and II/12 had only 13 LeO 451s between them. Groupement de Bombardement d'Assaut 18 (GBA 18) had only 12 of 25 Breguet 693s left. [63] GB I/34 and II/34 could muster eight aircraft out of 22 Amiot 143s, I/38 seven out of 12, and II/38 six out of 11. [64] All of these groups were sent to Sedan on 14 May. Escort was given from Groupement de Chasse (Fighter Groups, or GC). GC III/7 with 12 Morane 406s, 12 Bloch 152s of I/8 and nine Dewoitine D.520s of I/3 took part. GBA 18 was escorted by 15 Bloch 152s of GC I/8. The missions cost the French five bombers, two from ground fire. [9] [65] After this date, the French bomber forces were eliminated from the fight over Sedan. The major efforts were now made by the AASF. [66]

The Allied bombers received mostly poor protection. Only 93 fighter sorties, (60 by the French) were flown. [46] The French lost 21 fighters in the operation. [46] The German air defence was soon reinforced by Jagdgeschwader 26 and Jagdgeschwader 27 (Fighter Wings 26 and 27). [60] One of the premier German fighter units responsible for the heavy loss rate was Jagdgeschwader 53 (Fighter Wing 53), who later engaged French bombers who tried to succeed where the AASF failed. The attacks failed as they were uncoordinated. Along with fighter aircraft, the Germans had assembled powerful flak concentrations in Sedan. The FlaK battalions of the 1st, 2nd and 10th Panzer Divisions numbered 303 anti-aircraft guns. [67] This force was built around the 102nd FlaK Regiment with its 88 mm, 37 mm, and rapid fire 20 mm weapons. [5] So heavy was the defensive fire that the Allied bombers could not concentrate over the target. Allied bomber pilots called it "hell along the Meuse". [67] On 14 May, the Allies flew 250 sorties, the French losing 30 (another source states 21) [46] and the RAF losing 20 fighter aircraft. [9] Another 65 were heavily damaged. [9] Out of 109 RAF bombers dispatched, 47 were shot down. [9] This meant 167 aircraft had been lost against one target. [9] Bruno Loerzer called 14 May "the day of the fighter". [46]

The German Generals, in particular Guderian, were relieved that the Luftwaffe had prevented the Allied bombers from knocking out their supply bridges. By nightfall, at least 600 tanks, including those of the 2nd Panzer Division which had to use the 1st Panzer Division's bridge at Gaulier (owing to theirs not having yet been constructed), were across the Meuse. The German victory in the air battle had been decisive. [68]

French counter-offensive

Charles Huntziger, commanding the Second Army was unconcerned by the capture of Sedan, or of the collapse of French defences in the face of air attack. He expected considerable French reserves, particularly X Corps, to stabilise the front. The forces at the French commander's disposal were formidable. Guderian's decision to strike north west left the 10th Panzer Division protecting the bridgehead alone. Against this force was the XXI Corps (3d Armoured Division, 3d Motorised Infantry Division, 5th Light Cavalry Division, 1st Cavalry Brigade) under Flavigny. A second group, consisting of the 2d Light Cavalry Division and 3d Tank Division reinforced Flavigny. X Corps, with the 12th and 64th Reconnaissance Battalions, elements of the 71st Infantry Division, 205th Infantry Regiment, the 4th Tank Battalion were also to join the attack. The French had nearly 300 tanks, with 138 main battle tanks consisting of Hotchkiss and Char B1-Bis. [69]

The French tanks had heavier armour and armament than the Panzers. The Panzer IV had 30 mm of armour, while the Hotchkiss had 45 mm, and the Char B1 had 60 mm of protection. Moreover, its main armament, one 47 mm and one 75 mm gun, outmatched all the German tanks. In an open field engagement, Guderian's armour stood little chance. Two-thirds of his units were equipped with Panzer I and IIs. Just 30 of the Panzer IVs were on his order of battle. However, one crucial disadvantage of the French tanks, considered as a very broad whole, was their low endurance. They needed refuelling after just two hours. They were also slow in speed, complicating high tempo operations. [70]

Missed chance

During 14 May, General Lafontaine had moved the 55th Infantry Division's command post from its position on the Marfee heights to Bulson, 10–11 kilometres (6–7 mi) south of Sedan. The French had prepared, to an extent, for a German breakthrough at Sedan, and accordingly placed X Corps available for a counter-attack. It was to occupy the Bulson position on the Chéhéry–Bulson–Haraucourt axis and strike at the Meuse bridgeheads. The terrain included heavily wooded areas, and the units left behind convinced General Charles Huntziger, commander of the French Second Army, that they would be able to hold Bulson, and the Germans would not be able to exploit their tactical victory at Sedan on 14 May. [71]

The Germans suffered a seven-hour delay in getting their armour across the bridge from 01:20-07:30, which could have been disastrous for the Panzer divisions. The French had already initiated plans for counter-attacks with armour on the German-held bridgehead during the night but delays in bringing up forces, procrastination (inclined towards momentary adaptation towards defensive stancing and posturing), and hesitation on the part of local overall French command at large, made worse by mistaken intelligence-reports and by the resulting confusion from the panic and retreat of the infantry who had also abandoned their positions and artillery as part of the "panic of Bulson", [72] made an attack possible only in the morning of 14 May. The commander of X Corps' artillery, Colonel Poncelet, had tried to keep his units where they were, but had reluctantly ordered a retreat. [72] This decision resulted in the Corps artillery battalions abandoning many heavy artillery pieces and caused the collapse of the 55th Infantry Division ("panic of Bulson") and a partial collapse of the 71st Infantry Division. [72] Poncelet killed himself a few days later. [72]

On 13–14 May, the Germans were vulnerable. A strong attack at this point by the French armoured units could have prevented Guderian from breaking out of the Meuse bridgeheads and changed the outcome of the campaign. However, the French commanders, already deeply schooled and versed in the rather staunchly defensively-focused broad, generalized doctrine of methodological warfare, were located far to the rear, which meant they lacked a real-time and up-to-date picture of the battle. The French forces in the area were also hindered by mistaken intelligence-reports of which suggested that German tanks had already crossed the Meuse river, several hours before when the first German tank actually crossed the Meuse river. When intelligence did filter through, it was out-of-date. This was to prove fatal, especially coupled with the case of the matter that the French generalship at large was expecting a considerably more prolonged process of initial German assault phase and overall attack effort as a whole. [73]

Race to Bulson

The race to Bulson ridge began at 16:00 on 13 May. At 07:30 on 14 May, French armour advanced to Bulson ridge with a view to seizing the high ground vacated by the infantry of the 55th Infantry Division on 13 May. [68] But the main, primary objective was to destroy the German bridgeheads. While that may have been possible on 13 May, the odds had shifted against the French. [68]

The X Corps attack involved a strike on the left flank by the 213th Infantry Regiment and 7th Tank Battalion, and on the right flank by the 205th Infantry Regiment and 4th Tank Battalion. [71] [74] The right flanking force arrived late, so the 213th Infantry and the 7th Tank Battalion advanced alone on the north axis. It was thought that the 213th could reach an area in between Chéhéry and Bulson in one hour fifty minutes and the 7th Tank Battalion in two hours. [71] Yet it was not until 17 hours after the original order to advance to Bulson that the lead French tanks reached the Bulson ridge. They found the Germans had beaten them there by a few minutes. [71]

Lafontaine had hesitated over the 24 hours since the afternoon of 13 May. He spent hours reconnoitring the terrain, sometimes trying to contain and reason with fleeing, routing scores of French infantrymen and artillerymen of the 55th and 71st Infantry Divisions, and travelling around the area to various regimental headquarters, looking for his Corps commander, General Gransard (whom was deliberately reconnoitring the terrain, for some time, at that relative point in time), for an order to attack, and, in the meantime, extemporarily assessing and conferring with some local command personnel. Owing to this Lafontaine also delayed issuing orders to the tactical attack units until 05:00 on 14 May, by which time the Germans had consolidated their bridgehead and the Panzer divisions' combined arms infantry teams were already advancing inland to Bulson. Lafontaine had had a mission plan since 20:00 on 13 May to defeat the Germans and retake the Meuse bridgeheads, but he waited for an order to proceed. Lafontaine's need for an order was contrary to the unit actions of the Germans, who operated the tactically more efficient Auftragstaktik (Mission Command) system. Ultimately, Lafontaine had squandered valuable hours essential for a prompt, perhaps opportune and timely, perhaps potentially decisive counter-attack effort. [75]

The French had an opportunity to throw the Germans back into the Meuse but they missed their chance owing to poor staff-work. The 1st Panzer Division had struggled to advance as quickly as it would have liked, and was jammed on the roads leading out of Gaulier and Sedan. Moreover, the German soldiers were exhausted after a five-day advance. A quick counter thrust by just two infantry regiments and two tank battalions would have "plunged the Germans into crisis". [76] Even a failed attack, and the holding of Bulson, would have allowed it to be used by formations of the Second French Army and the tank units, including the French 3rd Armoured Division, of General Jean Adolphe Louis Robert Flavigny's powerful French XXI Corps which were moving up from the Maginot line area in the south. [76] [77]

That said, however, additionally, the French lacked neither relatively mobile tanks nor relatively offensively-intended tanks, in the local area of battle just as well so, for the most part, as in the whole broad Western European theatre of war and campaign of military operations of the time. French military doctrine dictated that the tanks, mostly FCM 36s, predominantly and primarily designed and intended as basically defensive-oriented infantry-support units, were to advance with the infantry. The speed of the FCM 36 was not designed to go any faster for this reason, so its top speed was only 24 km/h (15 mph). [68] It took from 07:30 to 08:45 on 14 May for the French armour to traverse the last 2 kilometres (1.2 mi) to the ridge. [68] Lead elements of the 1st and 2nd Panzer Divisions had reached the ridge just minutes before, having travelled 9 kilometres (5.6 mi) in less time. [68] But the initial clash was not in the Germans' favour. Instead of making sure the medium Panzer III and Panzer IV tanks had priority in crossing the Meuse, the Germans had sent few across, and the van of the advance contained mostly lightly armed and lightly armoured although faster Panzer Is and Panzer IIs. [68]

The initial encounters took place as the Battle of Hannut was being fought in Belgium. The results were much the same. On the southern face of Bulson, General Friedrich Kirchner, commander of the 1st Panzer Division, suffered several tactical reverses and saw the 37mm shells from his 3.7 cm PaK 36 anti-tank guns and Panzer IIIs bounce off the more heavily armoured French tanks. [68] A number of the German tanks were knocked out in rapid succession. [68] The Germans had to hold the French at the ridge. Kirchner was forced to send in his tanks in dribs and drabs, tactics which Guderian hated, but which he himself decided there was no other recourse. [68] It was once again the German tanks' radio equipment that enabled them to move around quickly and communicate with one another, to change the point of defence or attack quickly. The speed of the German tanks also enabled them to offset their inferiority in combat power to the French tanks. [16] Often, the Panzer III and IVs could speed into the rear of French formations, closing quickly and knocking out the French armour from the rear. [16] The Germans noted the particular weakness between the chassis and turret of the French tanks, which were vulnerable to their fire. [16]

The French artillery concealed in wooded areas proved more potent than the tanks. The German 1st Panzer Company was wiped out by French artillery, and pulled back with just one battleworthy tank. The Company retreated under the cover of part of the ridge, and moved its single tank back and forth, simulating the presence of many German tanks. Diverted from their success at Gaulier, near Sedan, the 2nd Panzer Company was rushed to the spot and managed to delay the French armoured advance. The Großdeutschland Infantry Regiment's late arrival tilted the scales. They managed to eliminate the anti-tank lines and entrenched French infantry. [78]

On the left side of the Bulson ridge, the Germans encountered 13 French tanks with support from infantry near Chéhéry. The Germans' advance intended to strike at Connage to the south of the town of Chéhéry, to outflank the French. Kirchner reacted quickly, ordering two anti-tank platoons to be set up at Connage. The 37 mm guns struggled to halt the French armour which then outflanked the position at Connage by moving to the west while the infantry advanced from the south east on the German right flank. Fortunately the 43rd Assault Engineer Battalion and the 8th Company, 2nd Battalion, 2nd Panzer Regiment arrived and pushed the French back to the town of Chémery-sur-Bar, some 5 kilometres (3.1 mi) south west of Bulson, and due south of Connage. [79]

At 10:45, Lafontaine ordered a retreat and Guderian finally got heavy artillery from the Großdeutschland Infantry Regiment. The 88 mm dual role artillery guns and the heavier Panzer III and IVs reached the area of the battle. By this time, the French 7th Tank Battalion had been wiped out and the 213th Infantry Regiment had been devastated. [79] Only 10 French tanks, out of 40, remained. [79] In the two pitched battles the 7th Tank Battalion fought that day they lost 10 from 13. [74] Delays on the right flank meant the 205th Infantry Regiment and 4th Tank Battalion did not reach their starting line until 10:45, by which time the battle on the left wing had been lost and further attacks on the right would have made little sense. [79] The 1st Panzer Division's victory parade was held in Chemery at 12:00, but it was cut short when the Luftwaffe bombed the square by mistake inflicting a few casualties. [79]

Battle of Stonne

The German High Command did not want to exploit the victory at Sedan and Bulson until the German infantry divisions had caught up with the three Panzer divisions. To Guderian, this was madness and would throw away the victory at Sedan and allow the enemy time to recover and reorganise its still formidable armoured units. Guderian decided to push for the Channel, even if it meant ignoring the High Command and Hitler himself. [80] Guderian ordered the 10th Panzer Division and Großdeutschland Infantry Regiment to hold the Sedan bridgehead, while the 1st and 2nd Panzer Divisions struck north west, towards the Channel. Now that they were pushing largely at an 'open door', the 1st and 2nd Panzer Divisions advanced into the undefended French rear with speed. [81]

The Sedan bridgeheads were still not safe. French forces were massing to the south. Guderian decided it was better to mount an aggressive defence given the lack of any suitable anti-tank weapons for a defensive battle. The better option would be to attack rather than defend. The advance of the 1st and 2nd Panzer Divisions had assisted his progress. They ran into and defeated elements of X Corps near Chemery. The French Corps was heading towards Sedan, but withdrew southward after the engagement. Any potential threat on the German western flank had been removed. [82]

Part of Guderian's original plan had called for a feint south towards and behind the Maginot Line, to mask the intention to thrust to the channel. General Franz Halder had dropped this from Fall Gelb, but Guderian resurrected it and ordered the 10th Panzer Division and Großdeutschland Infantry Regiment to attack across the Stonne plateau. In this innocuous town, a vicious two-day battle took place in which the Germans came face to face with the premier French tank, the Char B1-Bis, for the only time. One of these tanks, commanded by Pierre Billotte, proved invulnerable to German anti-tank fire and took 140 hits, and knocked out 13 German tanks (two PzKpfw IV and eleven PzKpfw III) and a number of anti-tank guns. It transpired that the French had concentrated their own armour there to mount another attack on the Sedan bridgeheads. The battle of Stonne took place between 15 and 17 May, and the town changed hands 17 times. Ultimately the failure of the French to hold it meant the final failure to eliminate the Sedan bridgeheads. [81]

The French offensive at Stonne was of vital importance. The town remained a base situated on high ground overlooking Sedan. The French could use it as a base from which to launch long-term attacks on Sedan. On 15 May, the battle began. The French committed the 3d Company, 49th Tank Battalion; 1st Company, 45th Tank Battalion; and the 2d Company, 4th Tank Battalion; the 1st Battalion, 67th Infantry Regiment; and the 1st Company, 51st Infantry Regiment. The French infantry were slow in their advance, which meant the armour outran them. Alone, the tanks tried to attack and failed. At this time, Stonne was held only by the 1st Battalion Großdeutschland supported by only nine of the Regiments 12 anti-tank artillery guns. As the French pressed forward, the weak German defence struggled to hold its ground. However, when one German platoon managed to knock out three French Char B1s the French tank crews panicked, and drove away to the south. It was a psychological victory for the Germans which encouraged their continued defence of the position. In the next attacks, they held their positions and fought. The town would fall to each side over the next 48 hours, as offensive followed counter-attack. The 10th Panzer sent its 1st Battalion, 69th Infantry Regiment to support the hard-pressed Großdeutschland. The Germans retook the town at 17:00 on 17 May, for the fourth time in nine hours. [83]

The Germans reinforced their defences on the night of 16 May with the VI Corps, consisting of the 16th Division under Heinrich Krampf, and 24th Infantry Division. It was a timely deployment. By this time the Großdeutschland had lost 570 men and were in need of rest and the Panzerjägerkompanie 14 (14th Panzer Anti-tank Company) had lost six of its 12 guns. It had also lost 12 dead and 65 wounded. Stonne was destroyed. Around 33 French tanks and 24 German Panzers were knocked out. With the IV Corps now supporting the German defence and counter-attacks, the town was captured for the 17th and final time at 17:45 on 17 May. [11]

Aftermath

The French defeat at Sedan left the Allied Army Groups in Belgium with sparse flank protection. The German attack, especially the breakout from the bridgeheads at Sedan, was so fast that there were hardly any major combats. Many French soldiers were in such shock that they were taken prisoner before they could offer resistance, which also explains the low casualty rates for both sides. The two assault engineer battalions under Korthals achieved the most important success. By eliminating the bunkers in the Bellevue sector, they made the breakthroughs of the 1st and 2nd Panzer Divisions possible. This was achieved without a single casualty. [10]

There is consensus among military historians that the Battle at Sedan sealed the fate of Belgium and France. On 14 May, the Allied forces had been wrongfooted and through the failures in deployment had effectively lost the campaign. The advance to the Channel would trap 1,700,000 soldiers and expel the Allies from Western Europe. [84]

Unfortunately for the Germans, the bulk of the British Army escaped from the port of Dunkirk. The German Army eventually won the ensuing Battle of Dunkirk, forcing the Allied Armies to leave behind large amounts of equipment, but failed, through controversial circumstances, to eliminate the British manpower trapped in the pocket. The encirclement destroyed the best units of the French Army, including a prisoner of war total of 40,000, but significant forces did escape (139,732 British and 139,037 French). [85] Some French forces would return to France and participate in the battles of June 1940, before surrendering along with the rest of the French armed forces on 25 June 1940, when the Armistice of 22 June took effect.

Operation Cycle

Operation Cycle is the name of the evacuation of Allied troops from Le Havre, in the Pays de Caux of Upper Normandy from 10–13 June 1940, towards the end of the Battle of France, during the Second World War. The operation was preceded by the better known rescue of 338,226 British and French soldiers from Dunkirk in Operation Dynamo (26 May – 4 June). On 20 May, the Germans had captured Abbeville at the mouth of the Somme and cut off the main Allied armies in the north. South of the river, the Allies improvised defences and made local counter-attacks, to dislodge the Germans from bridgeheads on the south bank and re-capture river crossings for an advance northwards to regain contact with the armies in northern France and Flanders.

Operation Citadel

Operation Citadel was a German offensive operation against Soviet forces in the Kursk salient during the Second World War on the Eastern Front that initiated the Battle of Kursk. The deliberate defensive operation that the Soviets implemented to repel the German offensive is referred to as the Kursk Strategic Defensive Operation. The German offensive was countered by two Soviet counter-offensives, Operation Polkovodets Rumyantsev and Operation Kutuzov. For the Germans, the battle was the final strategic offensive that they were able to launch on the Eastern Front. As the Allied invasion of Sicily began, Adolf Hitler was forced to divert troops training in France to meet the Allied threats in the Mediterranean, rather than use them as a strategic reserve for the Eastern Front. Germany's extensive loss of men and tanks ensured that the victorious Soviet Red Army enjoyed the strategic initiative for the remainder of the war.

10th Panzer Division (Wehrmacht) formation of the German Army during World War II

The 10th Panzer Division was a formation of the German Army during World War II. It was formed in Prague in March 1939, and served in the Army Group North reserve during the invasion of Poland of the same year.

A panzer division is one of the armored (tank) divisions in the Wehrmacht of Nazi Germany during World War II. This is a more restricted meaning than the German-language equivalent Panzerdivision, still used in the modern German Army of the Bundeswehr. In German-speaking countries, Panzerdivision is not immediately associated with the Wehrmacht as it is in English, as the German term simply means "armored division" and has no additional connotation.
