The Ulm Campaign was a series of French and Bavarian military maneuvers and battles to outflank and capture an Austrian army in 1805 during the War of the Third Coalition. It took place in the vicinity of and inside the Swabian (then Bavarian) city of Ulm. The French Grande Armée, led by Napoleon Bonaparte, comprised 210,000 troops organized into seven corps, and hoped to knock out the Austrian army in the Danube before Russian reinforcements could arrive. Through rapid marching, Napoleon conducted a large wheeling maneuver that captured an Austrian army of 23,000 under General Mack on 20 October at Ulm, bringing the total number of Austrian prisoners in the campaign to 60,000. The campaign is generally regarded as a strategic masterpiece and was influential in the development of the Schlieffen Plan in the late 19th century. [4]

First French Empire Empire of Napoleon I of France between 1804–1815

The First French Empire, officially the French Empire, was the empire of Napoleon Bonaparte of France and the dominant power in much of continental Europe at the beginning of the 19th century. Although France had already established an overseas colonial empire beginning in the 17th century, the French state had remained a kingdom under the Bourbons and a republic after the Revolution. Historians refer to Napoleon's regime as the First Empire to distinguish it from the restorationist Second Empire (1852–1870) ruled by his nephew as Napoleon III.

Electorate of Bavaria

The Electorate of Bavaria was an independent hereditary electorate of the Holy Roman Empire from 1623 to 1806, when it was succeeded by the Kingdom of Bavaria.

Austrian Empire monarchy in Central Europe between 1804 and 1867

The Austrian Empire was a Central European multinational great power from 1804 to 1867, created by proclamation out of the realms of the Habsburgs. During its existence, it was the third most populous empire after the Russian Empire and the United Kingdom in Europe. Along with Prussia, it was one of the two major powers of the German Confederation. Geographically, it was the third largest empire in Europe after the Russian Empire and the First French Empire. Proclaimed in response to the First French Empire, it partially overlapped with the Holy Roman Empire until the latter's dissolution in 1806.

The victory at Ulm did not end the war, since a large Russian army under Kutuzov was still near Vienna. The Russians withdrew to the northeast to await reinforcements and to link up with surviving Austrian units. The French followed and captured Vienna on 12 November. On 2 December the decisive French victory at Austerlitz removed Austria from the war. The resulting Treaty of Pressburg in late December brought the Third Coalition to an end and left Napoleonic France as the major power in Central Europe, leading to the War of the Fourth Coalition with Prussia and Russia the following year.

Vienna Capital city and state in Austria

Vienna is the federal capital and largest city of Austria, and one of the nine states of Austria. Vienna is Austria's primate city, with a population of about 1.9 million, and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union. Until the beginning of the 20th century, it was the largest German-speaking city in the world, and before the splitting of the Austro-Hungarian Empire in World War I, the city had 2 million inhabitants. Today, it has the second largest number of German speakers after Berlin. Vienna is host to many major international organizations, including the United Nations and OPEC. The city is located in the eastern part of Austria and is close to the borders of the Czech Republic, Slovakia, and Hungary. These regions work together in a European Centrope border region. Along with nearby Bratislava, Vienna forms a metropolitan region with 3 million inhabitants. In 2001, the city centre was designated a UNESCO World Heritage Site. In July 2017 it was moved to the list of World Heritage in Danger.

Battle of Austerlitz A battle of the Napoleonic Wars

The Battle of Austerlitz, also known as the Battle of the Three Emperors, was one of the most important and decisive engagements of the Napoleonic Wars. In what is widely regarded as the greatest victory achieved by Napoleon, the Grande Armée of France defeated a larger Russian and Austrian army led by Emperor Alexander I and Holy Roman Emperor Francis II. The battle occurred near the town of Austerlitz in the Austrian Empire. Austerlitz brought the War of the Third Coalition to a rapid end, with the Treaty of Pressburg signed by the Austrians later in the month. The battle is often cited as a tactical masterpiece, in the same league as other historic engagements like Cannae or Gaugamela.

War of the Fourth Coalition part of the Napoleonic Wars

The Fourth Coalition fought against Napoleon's French Empire and was defeated in a war spanning 1806–1807. Coalition partners included Prussia, Russia, Saxony, Sweden, and Great Britain. Several members of the coalition had previously been fighting France as part of the Third Coalition, and there was no intervening period of general peace. On 9 October 1806, Prussia joined a renewed coalition, fearing the rise in French power after the defeat of Austria and establishment of the French-sponsored Confederation of the Rhine. Prussia and Russia mobilized for a fresh campaign, and Prussian troops massed in Saxony.

Prelude

Europe had been by then embroiled in the French Revolutionary Wars since 1792. After five years of war, the French Republic subdued the First Coalition in 1797. A Second Coalition was formed in 1798 but this too was defeated by 1801. Britain remained the only opponent for the new French Consulate. In March 1802, France and Britain agreed to end hostilities under the Treaty of Amiens. For the first time in ten years, all of Europe was at peace. There were many problems between the two sides and implementing the agreements they had reached at Amiens seemed to be a growing challenge. Britain resented having to turn over all colonial conquests since 1793 and France was angry that British troops had not evacuated the island of Malta. [5] The tense situation only worsened when Napoleon sent an expeditionary force to crush the Haitian Revolution. [6] In May 1803, Britain declared war on France.

French Revolutionary Wars series of conflicts fought between the French Republic and several European monarchies from 1792 to 1802

The French Revolutionary Wars were a series of sweeping military conflicts lasting from 1792 until 1802 and resulting from the French Revolution. They pitted France against Great Britain, Austria and several other monarchies. They are divided in two periods: the War of the First Coalition (1792–97) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered a wide array of territories, from the Italian Peninsula and the Low Countries in Europe to the Louisiana Territory in North America. French success in these conflicts ensured the spread of revolutionary principles over much of Europe.

French First Republic republic governing France, 1792-1804

In the history of France, the First Republic, officially the French Republic, was founded on 22 September 1792 during the French Revolution. The First Republic lasted until the declaration of the First Empire in 1804 under Napoleon, although the form of the government changed several times. This period was characterized by the fall of the monarchy, the establishment of the National Convention and the Reign of Terror, the Thermidorian Reaction and the founding of the Directory, and, finally, the creation of the Consulate and Napoleon's rise to power.

United Kingdom of Great Britain and Ireland Historical sovereign state from 1801 to 1927

The United Kingdom of Great Britain and Ireland was established by the Acts of Union 1800, which merged the kingdoms of Great Britain and Ireland.

Third Coalition

In December 1804, an Anglo-Swedish agreement led to the creation of the Third Coalition. British Prime Minister William Pitt spent 1804 and 1805 in a flurry of diplomatic activity to form a new coalition against France. Mutual suspicion between the British and the Russians eased in the face of several French political mistakes and by April 1805 the two had signed a treaty of alliance. [7] Having been defeated twice in recent memory by France and keen on revenge, [8] Austria also joined the coalition a few months later. [9]

William Pitt the Younger 18th/19th-century British statesman

William Pitt the Younger was a prominent British Tory statesman of the late-eighteenth and early-nineteenth centuries. He became the youngest UK Prime Minister in 1783 at the age of 24. He left office in 1801, but served as Prime Minister again from 1804 until his death in 1806. He was Chancellor of the Exchequer for most of his time as Prime Minister. He is known as "the Younger" to distinguish him from his father, William Pitt, 1st Earl of Chatham, called William Pitt the Elder or simply "Chatham", who had previously served as Prime Minister.

French military preparations

Prior to the formation of the Third Coalition, Napoleon had assembled the "Army of England," an invasion force meant to strike at the British Isles, around six camps at Boulogne in Northern France. Although they never set foot on British soil, Napoleon's troops received careful and invaluable training for any possible military operation. Although boredom quickly set in among the troops, Napoleon paid many visits to conduct lavish parades to maintain their morale. [10]

British Isles Group of islands in northwest Europe

The British Isles are a group of islands in the North Atlantic off the north-western coast of continental Europe that consist of the islands of Great Britain, Ireland, the Isle of Man, the Hebrides and over six thousand smaller isles. They have a total area of about 315,159 km2 and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland, and the United Kingdom of Great Britain and Northern Ireland. The islands of Alderney, Jersey, Guernsey, and Sark, and their neighbouring smaller islands, are sometimes also taken to be part of the British Isles, even though, as islands off the coast of France, they do not form part of the archipelago.

Boulogne-sur-Mer Subprefecture and commune in Hauts-de-France, France

Boulogne-sur-Mer, often called Boulogne, is a coastal city in Northern France. It is a sub-prefecture of the department of Pas-de-Calais. Boulogne lies on the Côte d'Opale, a touristic stretch of French coast on the English Channel between Calais and Normandy, and the most visited location in the region after Lille conurbation. Boulogne is its department's second-largest city after Calais, and the 60th-largest in France. It is also the country's largest fishing port, specialising in herring.

The men at Boulogne formed the core for what Napoleon would later call "La Grande Armée" (The Great Army). At the start, the French army had about 200,000 men organized into seven corps, which were large field units, each containing about 36 to 40 cannon each and capable of independent action until other corps could arrive. [11] On top, Napoleon created a cavalry reserve of 22,000 troopers organized into two cuirassier divisions, four mounted dragoon divisions and two divisions of dismounted dragoons and light cavalry, all supported by 24 artillery pieces. [11] By 1805, La Grande Armée had grown to a force of 350,000, [12] was equipped and trained. It possessed a competent officer class where almost all from sergeants to marshals had experience in the recent Revolutionary Wars.

Corps military unit size

Corps is a term used for several different kinds of organisation.

Cannon Class of artillery which fires at a low or flat trajectory

A cannon is a type of gun classified as artillery that launches a projectile using propellant. In the past, gunpowder was the primary propellant before the invention of smokeless powder in the 19th century. Cannon vary in caliber, range, mobility, rate of fire, angle of fire, and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. The word cannon is derived from several languages, in which the original definition can usually be translated as tube, cane, or reed. In the modern era, the term cannon has fallen into decline, replaced by guns or artillery if not a more specific term such as mortar or howitzer, except for high calibre automatic weapons firing bigger rounds than machine guns, called autocannons.

Cavalry soldiers or warriors fighting from horseback

Cavalry or horsemen are soldiers or warriors who fight mounted on horseback. Cavalry were historically the most mobile of the combat arms. An individual soldier in the cavalry is known by a number of designations such as cavalryman, horseman, dragoon, or trooper. The designation of cavalry was not usually given to any military forces that used other animals, such as camels, mules or elephants. Infantry who moved on horseback, but dismounted to fight on foot, were known in the 17th and early 18th centuries as dragoons, a class of mounted infantry which later evolved into cavalry proper while retaining their historic title.

Austrian military preparations

Archduke Charles, brother of the Austrian Emperor, had started to reform the Austrian army in 1801 by taking away power from the Hofkriegsrat (Aulic Council), the military-political council responsible for decision making in the Austrian armed forces. [13] Charles was Austria's best field commander, [14] but he was unpopular with the royal court and lost much influence when, against his advice, Austria decided to go to war with France.

Karl Mack became the new main commander in Austria's army, instituting reforms on the infantry on the eve of war that called for a regiment to be composed of four battalions of four companies rather than the older three battalions of six companies. The sudden change came with no corresponding officer training; new units were led by commanders who had not been given sufficient tactical training in using their units. [15]

Austrian cavalry forces were regarded as the best in Europe, but the detachment of many cavalry units to various infantry formations precluded the hitting power of their massed French counterparts, who could, at the orders of Napoleon, amass a whole corps of cavalry to influence the battle. [15]

Campaign

The Ulm Campaign lasted for nearly a month and saw the French army under Napoleon deliver blow after blow to the confused Austrians. It culminated on 20 October with the loss of an entire Austrian army.

Austrian plans and preparations

General Mack thought that Austrian security relied on sealing off the gaps through the mountainous Black Forest area in Southern Germany that had witnessed much fighting during the campaigns of the French Revolutionary Wars. Mack believed that there would be no action in Central Germany. Mack decided to make the city of Ulm the centerpiece of his defensive strategy, which called for a containment of the French until the Russians under Kutuzov could arrive and alter the odds against Napoleon. Ulm was protected by the heavily fortified Michelsberg heights, giving Mack the impression that the city was virtually impregnable from outside attack. [16]

Fatally, the Aulic Council decided to make Northern Italy the main theater of operations for the Habsburgs. Archduke Charles was assigned 95,000 troops and directed to cross the Adige River with Mantua, Peschiera, and Milan as the initial objectives. [17] The Austrians based an army of 72,000 men on Ulm. Nominally commanded by Archduke Ferdinand, the army's real authority was Mack. Austrian strategy required that Archduke John with 23,000 troops secure the Tyrol and provide the link between his brother Charles's army and his cousin Ferdinand's army. [17] The Austrians also detached individual corps to serve with the Swedish in Pomerania and the British in Naples, though these were designed to confuse the French and divert their resources.

French plans and preparations

The French concentrated around the Rhine from early to mid-September. 210,000 troops of the Grande Armee prepared to cross into Germany and encircle the Austrians. Ulm campaign - Invasion of Bavaria and French assembly on the Rhine, 2-25 September 1805.jpg
The French concentrated around the Rhine from early to mid-September. 210,000 troops of the Grande Armée prepared to cross into Germany and encircle the Austrians.

In both the campaigns of 1796 and 1800, Napoleon had envisaged the Danube theater as the central focus of French efforts, but in both instances the Italian theater became the most important. The Aulic Council thought Napoleon would strike in Italy again. Napoleon had other intentions: 210,000 French troops would be launched eastwards from the camps of Boulogne and would envelop General Mack's exposed Austrian army if it kept marching towards the Black Forest. [1] Meanwhile, Marshal Murat would conduct cavalry screens across the Black Forest to fool the Austrians into thinking that the French were advancing on a direct west-east axis. The main attack in Germany would be supported by French assaults in other theaters: Marshal Masséna would confront Charles in Italy with 50,000 men of the Armée d'Italie, St. Cyr would march to Naples with 20,000 men, and Marshal Brune would patrol Boulogne with 30,000 troops against a possible British invasion. [18]

Murat and Bertrand conducted reconnaissance between the area bordering the Tyrol and the Main as Savary, chief of the planning staff, drew up detailed road surveys of the areas between the Rhine and the Danube. [18] The left wing of the Grande Armée would move from Hanover in northern Germany and Utrecht in the Netherland to fall on Württemberg; the right and center, troops from the Channel coast, would concentrate along the Middle Rhine around cities like Mannheim and Strasbourg. [18] While Murat was making demonstrations across the Black Forest, other French forces would then invade the German heartland and swing towards the southeast by capturing Augsburg, a move that was supposed to isolate Mack and interrupt the Austrian lines of communication. [18]

The French invasion

The French invasion in late September and early October caught the Austrians unprepared and severed their lines of communication. Ulm campaign - French strategic envelopment, 26 September-9 October 1805.jpg
The French invasion in late September and early October caught the Austrians unprepared and severed their lines of communication.

On 22 September Mack decided to hold the Iller line anchored on Ulm. In the last three days of September, the French began the furious marches that would place them at the Austrian rear. Mack believed that the French would not violate Prussian territory, but when he heard that Bernadotte's I Corps had marched through Prussian Ansbach, he made the critical decision to stay and defend Ulm rather than retreat to the south, which would have offered a reasonable opportunity at saving the bulk of his forces. [19] Napoleon had little accurate information about Mack's intentions or maneuvers; he knew that Kienmayer's Corps was sent to Ingolstadt east of the French positions, but his agents greatly exaggerated its size. [20] On 5 October Napoleon ordered Ney to join Lannes, Soult, and Murat in concentrating and crossing the Danube at Donauwörth. [21] The French encirclement, however, was not deep enough to prevent Kienmayer's escape: the French corps did not all arrive at the same place – they instead deployed on a long west-east axis – and the early arrival of Soult and Davout at Donauwörth incited Kienmayer to exercise caution and evasion. [21] Napoleon gradually became more convinced that the Austrians were massed at Ulm and ordered sizeable portions of the French army to concentrate around Donauwörth; on 6 October three French infantry and cavalry corps headed to Donauwörth to seal off Mack's escape route. [22]

Realizing the danger of his position, Mack decided to go on the offensive. On 8 October he commanded the army to concentrate around Günzburg and hoped to strike at Napoleon's lines of communication. Mack instructed Kienmayer to draw Napoleon further east towards Munich and Augsburg. Napoleon did not seriously consider the possibility that Mack would cross the Danube and move away from his central base, but he did realize that seizing the bridges at Günzburg would yield a large strategic advantage. [23] To accomplish this objective, Napoleon sent Ney's Corps to Günzburg, completely unaware that the bulk of the Austrian army was heading to the same destination. On 8 October, however, the campaign witnessed its first serious battle at Wertingen between Auffenburg's troops and those of Murat and Lannes.

Battle of Wertingen

Battle of Günzburg, 9 October 1805

For reasons not entirely clear, on 7 October Mack ordered Franz Xavier Auffenburg to take his division of 5,000 infantry and 400 cavalry from Günzburg to Wertingen in preparation for the main Austrian advance out of Ulm. [24] Uncertain of what to do and having little hope for reinforcements, Auffenburg was in a dangerous position. The first French forces to arrive were Murat's cavalry divisions Louis Klein's 1st Dragoon Division, Marc Antoine de Beaumont's 3rd Dragoon Division, and Nansouty's 1st Cuirassier Division. They began to assault the Austrian positions and were soon joined by Nicolas Oudinot's grenadiers, who were hoping to outflank the Austrians from the northeast. Auffenburg attempted a retreat to the southwest, but he was not quick enough: the Austrians lost nearly their entire force, 1,000 to 2,000 of which were taken prisoner. [25] The Battle of Wertingen had been an easy French victory.

The action at Wertingen convinced Mack to operate on the left (north) bank of the Danube instead of making a direct eastwards retreat on the right bank. This would require the Austrian army to cross to the north at Günzburg. On 8 October Ney was operating under Louis Alexandre Berthier's directions that called for a direct attack on Ulm the following day. Ney sent in Jean-Pierre Firmin Malher's 3rd Division to capture the Günzburg bridges over the Danube. In the Battle of Günzburg, a column of this division ran into some Tyrolean jaegers and captured 200 of them, including their commander Konstantin Ghilian Karl d'Aspré, along with two cannons. [26] The Austrians noticed these developments and reinforced their positions around Günzburg with three infantry battalions and 20 cannons. [26] Malher's division conducted several heroic attacks against the Austrian positions, but all failed. Mack then sent in Ignaz Gyulai with seven infantry battalions and fourteen cavalry squadrons to repair the destroyed bridges, but this force was charged and swept away by the delayed French 59th Infantry Regiment. [27] Fierce fighting ensued and the French finally managed to establish a foothold on the right (south) bank of the Danube. While the Battle of Günzburg was being fought, Ney sent Louis Henri Loison's 2nd Division to capture the Danube bridges at Elchingen, which were lightly defended by the Austrians. Having lost most of the Danube bridges, Mack marched his army back to Ulm. By 10 October Ney's corps had made significant progress: Malher's 3rd division had crossed to the right (south) bank, Loison's 2nd division held Elchingen, and Pierre Dupont de l'Étang's 1st Division was heading towards Ulm.

The strategic situation from 11 to 14 October. The French hurl themselves westwards to capture the Austrian army.

The demoralized Austrian army arrived at Ulm in the early hours of 10 October. Mack was deliberating his course of action and the Austrian army remained inactive at Ulm until the 11th. Meanwhile, Napoleon was operating under flawed assumptions: he believed the Austrians were moving to the east or southeast and that Ulm was lightly guarded. Ney sensed this misapprehension and wrote to Berthier that Ulm was, in fact, more heavily defended than the French originally thought. [28] During this time, the Russian threat to the east began to preoccupy Napoleon so much that Murat was given command of the right wing of the army, consisting of Ney's and Lannes's corps. [29] The French were separated in two massive wings at this point: the forces of Ney, Lannes, and Murat to the west were containing Mack while those of Soult, Davout, Bernadotte, and Auguste Marmont to the east were charged with guarding against any possible Russian and Austrian incursions. On 11 October Ney made a renewed push on Ulm; the 2nd and 3rd divisions were to march to the city along the right bank of the Danube while Dupont's division, supported by one dragoon division, was to march directly for Ulm and seize the entire city. The orders were hopeless because Ney still did not know that the entire Austrian army was stationed at Ulm.

The 32nd Infantry Regiment in Dupont's division marched from Haslach towards Ulm and ran into four Austrian regiments holding Boefingen. The 32nd carried out several ferocious attacks, but the Austrians held firm and repulsed every one. The Austrians flooded the battle with more cavalry and infantry regiments to Ulm-Jungingen hoping to score a knockout blow against Ney's corps by enveloping Dupont's force. Dupont sensed what was happening and preempted the Austrians by launching a surprise attack on Jungingen, during which he took as prisoner at least 1,000 of the Austrians. [30] Renewed Austrian attacks drove these forces back to Haslach, which the French managed to hold. Dupont was eventually forced to fall back on Albeck, where he joined Louis Baraguey d'Hilliers's foot dragoons division. The effects of the Battle of Haslach-Jungingen on Napoleon's plans are not fully clear, but the Emperor may have finally ascertained that the majority of the Austrian army was concentrated at Ulm. [31] Accordingly, Napoleon sent the corps of Soult and Marmont towards the Iller, meaning he now had four infantry and one cavalry corps to deal with Mack; Davout, Bernadotte, and the Bavarians were still guarding the region around Munich. [31] Napoleon did not intend to fight a battle across rivers and ordered his marshals to capture the important bridges around Ulm. He also began shifting his forces to the north of Ulm because he expected a battle in that region rather than an encirclement of the city itself. [32] These dispositions and actions would lead to a confrontation at Elchingen on the 14th as Ney's forces advanced on Albeck.

At this point in the campaign, the Austrian command staff was in full confusion. Ferdinand began to openly oppose Mack's command style and decisions, charging that the latter spent his days writing contradictory orders that left the Austrian army marching back and forth. [33] On 13 October Mack sent two columns out of Ulm in preparation for a breakout to the north: one under Johann Sigismund Riesch headed towards Elchingen to secure the bridge there and the other under Franz von Werneck went north with most of the heavy artillery. [34] Ney hurried his corps forward to reestablish contact with Dupont, who was still north of the Danube. Ney led Loison's division to the south of Elchingen on the right bank of the Danube to begin the attack. Malher's division crossed the river farther east and moved west toward Riesch's position. The field was a partially wooded flood plain, rising steeply to the hill town of Elchingen, which had a wide field of view. [35] The French cleared the Austrian pickets from a bridge, then a regiment boldly attacked and captured the abbey at the top of the hill at bayonet point. During the Battle of Elchingen, the Austrian cavalry was also defeated and Reisch's infantry fled toward Ulm. Ney was given the title Duke of Elchingen for his impressive victory. [36]

On 13 October Soult's IV Corps fell on Memmingen from the east. After a minor clash that resulted in 16 French casualties, General-Major Karl Spangen von Uyternesse surrendered 4,600 soldiers, eight guns, and nine colors. The Austrians were low on ammunition, cut off from Ulm, and completely demoralized by the confusion reigning at army headquarters. [37]

More actions took place on the 14th. Murat's forces joined Dupont at Albeck just in time to drive off an Austrian attack from Werneck; together Murat and Dupont beat the Austrians to the north in the direction of Heidenheim. By night on the 14th, two French corps were stationed in the vicinity of the Austrian encampments at Michelsberg, right outside of Ulm. [38] Mack was now in a dangerous situation: there was no longer any hope of escaping along the north bank, Marmont and the Imperial Guard were hovering at the outskirts of Ulm to the south of the river, and Soult was moving north from Memmingen to prevent the Austrians escaping south to the Tyrol. [38] Troubles continued with the Austrian command as Ferdinand overrode the objections of Mack and ordered the evacuation of all cavalry from Ulm, a total of 6,000 troopers. [39] Murat's pursuit was so effective, however, that only eleven squadrons joined Werneck at Heidenheim. [39] Murat continued his harassment of Werneck and forced him to surrender with 8,000 men at Treuchtlingen on 19 October; Murat also took an entire Austrian field park of 500 vehicles, then swept on towards Neustadt an der Donau and captured 12,000 Austrians. [39] [40]

Events at Ulm were now reaching a conclusion. On 15 October Ney's troops successfully charged the Michelsberg encampments and on the 16th the French began to bombard Ulm itself. Austrian morale was at a low point and Mack began to realize that there was little hope of rescue. On 17 October Napoleon's emissary, Ségur, signed a convention with Mack in which the Austrians agreed to surrender on 25 October if no aid came by that date. [39] Gradually, however, Mack heard of the capitulations at Heidenheim and Neresheim and agreed to surrender five days before schedule on 20 October. Fifteen hundred troops from the Austrian garrison managed to escape, but the vast majority of the Austrian force marched out on 21 October and laid down their arms without incident, all with the Grande Armée drawn up in a vast semicircle observing the capitulation (see infobox picture). [39] The officers were permitted to leave, pending their signatures on a parole in which they agreed not to take up arms against France until they were exchanged. More than ten general officers were included in this agreement, including Mack, Johann von Klenau, Maximilian Anton Karl, Count Baillet de Latour, Prince Liechtenstein, and Ignaz Gyulai. [41]

Aftermath

On 2 December 1805 the French crushed a combined Russo-Austrian army in the Battle of Austerlitz. Austria agreed to end her participation in the Third Coalition with the Treaty of Pressburg on 26 December. Austerlitz-baron-Pascal.jpg
On 2 December 1805 the French crushed a combined Russo-Austrian army in the Battle of Austerlitz. Austria agreed to end her participation in the Third Coalition with the Treaty of Pressburg on 26 December.

As the Austrians were marching out of Ulm to surrender, a combined Franco-Spanish fleet was being destroyed at the Battle of Trafalgar. This decisive British victory ended the naval threat from France and ensured British naval domination until World War I. Despite this setback, the Ulm Campaign had been a spectacular victory and had witnessed the elimination of an entire Austrian army at very little cost for the French. The 8th bulletin of the Grande Armée described the scale of the achievement:

Marshal Augereau's arrival from Brest with the newly formed VII Corps gave the French one more piece of good news. In the Capitulation of Dornbirn on 13 November, Franjo Jelačić's division was cornered and forced to surrender. The Russians withdrew to the northeast after Mack's capitulation and Vienna fell on 12 November. The Allies were thoroughly defeated at the Battle of Austerlitz in December and Austria was permanently knocked out of the Third Coalition a few weeks later. The French victory highlighted the effectiveness of la manoeuvre sur les derrières, a special type of strategic envelopment first used by Napoleon in his Italian campaign in 1796. [42] The maneuver called for a pinning force that would occupy a broad front of the enemy line while other supporting units positioned themselves at a specific location in the enemy's flank or rear. [43] As the enemy became more embroiled with the pinning force, the flanking troops would attack at a critical spot and seal the victory. In the Ulm Campaign, Murat's cavalry served as the pinning force that fooled the Austrians into thinking the main French attack would come from the Black Forest. As Murat lulled the Austrians towards Ulm, the main French forces crashed through Central Germany and separated Mack's army from the other theaters of the war.

The Schlieffen Plan, emphasizing maneuver and envelopment, owed much to the Ulm Campaign

The Ulm Campaign is considered to be one of the greatest historical examples of a strategic turning movement. [44] Historians often analyze the campaign on a wide strategic level that does not include tactical confrontations, even though these were common and relevant. [44] The decisive victory at Ulm is also believed to be a product of the long training and preparation the Grande Armée received at the camps of Boulogne. [44] The Grande Armée carried little baggage, invaded enemy territory at harvest time, and marched far faster than the Austrians had expected. [45] The campaign highlighted the utility of the Corps d'Armée system; corps went on to become the fundamental strategic building block for the major wars in the nineteenth and twentieth centuries. [46] A typical corps might have three infantry divisions, a light cavalry brigade for reconnaissance, and reserve artillery batteries in addition to those attached to each division; their increased size allowed them to fight without support for long periods of time, as Ney did, and their durability permitted them to spread out and subsist by requisitioning local food. [45] The French needed about one eighth the transport used by contemporary armies, giving them a level of mobility and flexibility unseen at that time: invasions of South Germany by Marlborough or Moreau covered a narrow front, but the Grande Armée invaded in 1805 on a front that was 100 miles (161 km) wide, an action that took the Austrians by complete surprise and caused them to underestimate the gravity of the situation.

The Baltic was dominated by Russia, something Britain wasn't comfortable with since it provided valuable commodities like timber, tar and hemp, crucial supplies to Britain's empire.

Meanwhile, French territorial rearrangements in Germany occurred without Russian consultation and Napoleon's annexations in the Po valley increasingly strained relations between the two.

On the other hand, Treuchtlingen is a far better candidate since it is in the expected direction, that is, 48 km northeast of Neresheim and 91 km northeast of Ulm. Chandler also names Neustadt, which could be either Neustadt am der Donau (148 km east of Ulm!) or a mistake.
