The Battle of the Somme, also known as the Somme offensive, was a battle of the First World War fought by the armies of the British Empire and the French Third Republic against the German Empire. It took place between 1 July and 18 November 1916 on both sides of the upper reaches of the river Somme in France. The battle was intended to hasten a victory for the Allies. More than three million men fought in the battle, of whom more than one million were either wounded or killed, making it one of the deadliest battles in all of human history.
The First Battle of Ypres was a battle of the First World War, fought on the Western Front around Ypres, in West Flanders, Belgium. The battle was part of the First Battle of Flanders, in which German, French, Belgian armies and the British Expeditionary Force (BEF) fought from Arras in France to Nieuwpoort (Nieuport) on the Belgian coast, from 10 October to mid-November. The battles at Ypres began at the end of the Race to the Sea, reciprocal attempts by the German and Franco-British armies to advance past the northern flank of their opponents. North of Ypres, the fighting continued in the Battle of the Yser (16–31 October), between the German 4th Army, the Belgian army and French marines.
The Hindenburg Line was a German defensive position built during the winter of 1916–1917 on the Western Front in France during the First World War. The line ran from Arras to Laffaux, near Soissons on the Aisne. In 1916, the Battle of Verdun and the Battle of the Somme left the German western armies exhausted and on the Eastern Front, the Brusilov Offensive had inflicted huge losses on the Austro-Hungarian armies and forced the Germans to take over more of the front. The declaration of war by Romania had placed additional strain on the German army and war economy.
The Race to the Sea took place from about 17 September – 19 October 1914 during the First World War, after the Battle of the Frontiers and the German advance into France. The invasion had been stopped at the First Battle of the Marne (5–12 September) and was followed by the First Battle of the Aisne (13–28 September), a Franco-British counter-offensive. The term describes reciprocal attempts by the Franco-British and German armies to envelop the northern flank of the opposing army through the provinces of Picardy, Artois and Flanders, rather than an attempt to advance northwards to the sea. The "race" ended on the North Sea coast of Belgium around 19 October, when the last open area from Diksmuide to the North Sea was occupied by Belgian troops who had retreated after the Siege of Antwerp. The outflanking attempts had resulted in a number of encounter battles but neither side was able to gain a decisive victory.
The first day on the Somme, 1 July 1916, was the beginning of the Battle of Albert (1–13 July), the name given by the British to the first two weeks of the 141 days of the Battle of the Somme in the First World War. Nine corps of the French Sixth Army and the British Fourth and Third armies attacked the German 2nd Army from Foucaucourt south of the Somme, northwards across the Somme and the Ancre to Serre and at Gommecourt, 2 mi (3.2 km) beyond, in the Third Army area. The objective of the attack was to capture the German first and second defensive positions from Serre south to the Albert–Bapaume road and the first position from the road south to Foucaucourt.
The Battle of the Frontiers comprised battles fought along the eastern frontier of France and in southern Belgium, shortly after the outbreak of the First World War. The battles resolved the military strategies of the French Chief of Staff General Joseph Joffre with Plan XVII and an offensive adaptation of the German Aufmarsch II deployment plan by Helmuth von Moltke the Younger. The German concentration on the right (northern) flank, was to wheel through Belgium and attack the French in the rear.
The Second Battle of Artois from 9 May to 18 June 1915, took place on the Western Front during the First World War. A German-held salient from Reims to Amiens had been formed in 1914 which menaced communications between Paris and the unoccupied parts of northern France. A reciprocal French advance eastwards in Artois could cut the rail lines supplying the German armies between Arras and Reims. French operations in Artois, Champagne and Alsace from November–December 1914, led General Joseph Joffre, Generalissimo and head of Grand Quartier Général (GQG), to continue the offensive in Champagne against the German southern rail supply route and to plan an offensive in Artois against the lines from Germany supplying the German armies in the north.
The Great Retreat, also known as the retreat from Mons, was the long withdrawal to the River Marne in August and September 1914 by the British Expeditionary Force (BEF) and the French Fifth Army. The Franco-British forces on the Western Front in the First World War had been defeated by the armies of the German Empire at the Battle of Charleroi and the Battle of Mons. A counter-offensive by the Fifth Army, with some assistance from the BEF, at the First Battle of Guise failed to end the German advance and the retreat continued over the Marne. From 5 to 12 September, the First Battle of the Marne ended the Allied retreat and forced the German armies to retire towards the Aisne River and to fight the First Battle of the Aisne (13–28 September). Reciprocal attempts to outflank the opposing armies to the north known as the Race to the Sea followed from (17 September to 17 October).
Michel-Joseph Maunoury was a commander of French forces in the early days of World War I who was posthumously elevated to the dignity of Marshal of France.
Winter operations 1914–1915 is the name given to military operations during the First World War, from 23 November 1914 – 6 February 1915, in the 1921 report of the British government Battles Nomenclature Committee. The operations took place on the part of the Western Front held by the British Expeditionary Force (BEF), in French and Belgian Flanders.
The Battle of Arras, was an attempt by the French Army to outflank the German Army, which was attempting to do the same thing during the "Race to the Sea", the reciprocal attempts by both sides, to exploit conditions created during the First Battle of the Aisne. At the First Battle of Picardy (22–26 September) each side had attacked expecting to advance round an open northern flank and found instead that troops had arrived from further south and extended the flank northwards.
The Battle of La Bassée was fought by German and Franco-British forces in northern France in October 1914, during reciprocal attempts by the contending armies to envelop the northern flank of their opponent, which has been called the Race to the Sea. The 6th Army took Lille before a British force could secure the town and the 4th Army attacked the exposed British flank further north at Ypres. The British were driven back and the German army occupied La Bassée and Neuve Chapelle. Around 15 October, the British recaptured Givenchy-lès-la-Bassée but failed to recover La Bassée.
The Battle of Messines was fought in October 1914 between the armies of the German empire and British empire and France as part of what came to be called the Race to the Sea, reciprocal attempts by the German and Entente armies to attack beyond the northern flank of their opponent. The attempts to turn the opponent's northern flank led to several meeting engagements until the North Sea left neither side with a flank to aim at. The battle was fought between the river Douve and the Comines–Ypres canal.
The Battle of Armentières was fought by German and Franco-British forces in northern France in October 1914, during reciprocal attempts by the armies to envelop the northern flank of their opponent, which has been called the Race to the Sea. Troops of the British Expeditionary Force (BEF) moved north from the Aisne front in early October and then joined in a general advance with French troops further south, pushing German cavalry and Jäger back towards Lille until 19 October. German infantry reinforcements of the 6th Army arrived in the area during October.
The First Battle of Picardy(22–26 September 1914) took place during the Race to the Sea (17 September – 19 October) and the First Battle of the Aisne (13–28 September). The "race" was a Franco-British counter-offensive, which followed the Battle of the Frontiers and the German advance into France during the Great Retreat, which ended at the First Battle of the Marne (5–12 September). The term describes reciprocal attempts by the Franco-British and German armies to envelop the northern flank of the opposing army, through Picardy, Artois and Flanders.
The Capture of Gueudecourt is a tactical incident of the First World War during the Battle of the Somme. The village lies on the Le Sars–Le Transloy road, north-east of Flers and north-west of Lesbœufs. Behind Gueudecourt lay open country which had hardly been shelled with Le Barque in the middle distance and then Bapaume beyond. German troops had passed through the village in late September 1914 during the First Battle of Albert, part of reciprocal attempts by the German and Franco-British armies to advance round the northern flank of their opponent during the operations known as the Race to the Sea. The village became a backwater until 1916 when the Germans built a third defensive position behind the Somme front, in preparation for the British–French offensive being prepared on the Somme.
The Capture of Lesbœufs [25 September 1916] was a tactical incident in the Battle of the Somme. Lesbœufs was a village on the D 74 between Gueudecourt and Morval, about 30 miles (48 km) north-east of Amiens; Le Transloy lies to the north-west and Bapaume is to the north. French Territorials fought the II Bavarian Corps on the north bank of the Somme in late September 1914, after which the front line moved west past the village. Little military activity occurred round the village until the beginning of the Battle of the Somme, when German troops passed through the village in the first weeks of the battle. During the Battle of Flers–Courcelette (15–22 September), advances by the right flank corps of the British Fourth Army, brought the front line forward to the Gallwitz Riegel trenches west of Lesbœufs but exhaustion prevented the British from reaching their third objective, a line east of Morval, Lesbœufs and Gueudecourt.
The Capture of Eaucourt l'Abbaye was a tactical incident during the Battle of the Somme. Eaucourt is about 16 mi (26 km) south of Arras, at the junction of the D 929 and the D 10E roads. Eaucourt l'Abbaye (Eaucourt) is north-west of Martinpuich, south-east of Le Sars, south of the Butte de Warlencourt west of Gueudecourt and north-west of Flers. Eaucourt was a group of farm buildings in an enclosure built on the site of an Augustinian abbey, on a side road from Le Sars off the main Albert–Bapaume highway. Destremont Farm to the south-west of Le Sars and a derelict quarry south of Eaucourt had been fortified by the Germans.
The Capture of Mametz took place on 1 July 1916, when the British Fourth Army attacked the German 2nd Army on the Western Front, during the first day of the Battle of the Somme. Mametz is a village on the D 64 road, about 20 mi (32 km) north-east of Amiens and 4 mi (6.4 km) east of Albert. Fricourt lies to the west, Contalmaison is to the north, Montauban to the north-east and Carnoy and Maricourt are to the south-east. Mametz Wood is 1,000 yd (910 m) to the north-west and before 1914, the village was the fifth largest in the area, with about 120 houses and had a station on the line from Albert to Péronne. During the Battle of Albert the II Bavarian Corps attacked westwards north of the Somme but was fought to a standstill east of Mametz. Reinforced by the XIV Reserve Corps the Germans on the north side of the Somme attacked again and took Mametz on 29 September. After a mutually costly battle for Fricourt, where the French were eventually forced out, the front line stabilised and both sides began to improvise defences. In mid-December a French local attack in the Mametz area was a costly failure.
The Battle of Hébuterne, took place from 7 to 13 June 1915 on the Western Front in Picardy, during the First World War. The French Second Army conducted the attack as part of a general action by several French armies, to hinder the movement of German reserves to Vimy Ridge, during the decisive action of the Tenth Army in the Second Battle of Artois.
