The Third Battle of Ypres, also known as the Battle of Passchendaele, was a campaign of the First World War, fought by the Allies against the German Empire. The battle took place on the Western Front, from July to November 1917, for control of the ridges south and east of the Belgian city of Ypres in West Flanders, as part of a strategy decided by the Allies at conferences in November 1916 and May 1917. Passchendaele lies on the last ridge east of Ypres, 5 mi (8 km) from Roulers, a junction of the Bruges-(Brugge)-to-Kortrijk railway. The station at Roulers was on the main supply route of the German 4th Army. Once Passchendaele Ridge had been captured, the Allied advance was to continue to a line from Thourout to Couckelaere (Koekelare).
The Second Battle of the Marne was the last major German offensive on the Western Front during the First World War. The attack failed when an Allied counterattack, led by French forces and supported by several hundreds of Renault FT tanks, overwhelmed the Germans on their right flank, inflicting severe casualties. The German defeat marked the start of the relentless Allied advance which culminated in an armistice with Germany about 100 days later.
The Battle of Craonne was a battle between an Imperial French army under Emperor Napoleon I opposing a combined army of Imperial Russians and Prussians led by Prussian Field Marshal Gebhard Leberecht von Blücher. The War of the Sixth Coalition engagement began when the bulk of Napoleon's army tried to drive Mikhail Semyonovich Vorontsov's 22,000 Russians off the Chemin des Dames plateau to the west of Craonne. After a bitter struggle, Napoleon's attacks compelled Vorontsov's force to withdraw, but French casualties exceeded Russian losses. While the battle raged, Blücher's attempt to turn Napoleon's east flank ended in failure due to poor planning.
The German spring offensive, also known as Kaiserschlacht or the Ludendorff offensive, was a series of German attacks along the Western Front during the First World War, beginning on 21 March 1918. Following American entry into the war in April 1917, the Germans decided that their only remaining chance of victory was to defeat the Allies before the United States could ship soldiers across the Atlantic and fully deploy its resources. The German Army had gained a temporary advantage in numbers as nearly 50 divisions had been freed by the Russian defeat and withdrawal from the war with the Treaty of Brest-Litovsk.
In France, the Chemin des Dames is part of the route départementale D18 and runs east and west in the Aisne department, between in the west, the Route Nationale 2, and in the east, the D1044 at Corbeny. It is some 30 kilometres (19 mi) long and runs along a ridge between the valleys of the rivers Aisne and Ailette.
The Battle of Amiens, also known as the Third Battle of Picardy, was the opening phase of the Allied offensive which began on 8 August 1918, later known as the Hundred Days Offensive, which ultimately led to the end of World War I. Allied forces advanced over 11 kilometres (7 mi) on the first day, one of the greatest advances of the war, with Gen Henry Rawlinson's British Fourth Army, with nine of its 19 divisions supplied by the fast-moving Australian Corps of Lt General John Monash and Canadian Corps of Lt General Arthur Currie, and Gen Marie Eugène Debeney's French First Army playing a decisive role. The battle is also notable for its effects on both sides' morale and the large number of surrendering German forces. This led Erich Ludendorff to later describe the first day of the battle as "the black day of the German Army". Amiens was one of the first major battles involving armoured warfare.
The Battle of Château-Thierry was fought on July 1, 1918 and was one of the first actions of the American Expeditionary Forces (AEF) under General John J. Pershing. It was a battle in World War I as part of the Second Battle of the Marne, initially prompted by a German Spring Offensive. German and local actions at Château-Thierry recommenced on May 31 to July 22, 1918, against the AEF, an American Expeditionary Force, consisting of troops from both the United States Army and Marine Corps units. These units from the 2nd US Division were the newest troops on the front in France and just barely out of training.
The Battle of Arras, also known as the Second Battle of Arras, was a British offensive on the Western Front during the First World War. From 9 April to 16 May 1917, British troops attacked German defences near the French city of Arras on the Western Front. The British achieved the longest advance since trench warfare had begun, surpassing the record set by the French Sixth Army on 1 July 1916. The British advance slowed in the next few days and the German defence recovered. The battle became a costly stalemate for both sides and by the end of the battle, the British Third Army and the First Army had suffered about 160,000 casualties and the German 6th Army about 125,000.
The Hundred Days Offensive was a series of massive Allied offensives that ended the First World War. Beginning with the Battle of Amiens on the Western Front, the Allies pushed the Imperial German Army back, undoing its gains from the German spring offensive.
The Battle of the Lys, also known as the Fourth Battle of Ypres, was fought from 7 to 29 April 1918 and was part of the German spring offensive in Flanders during the First World War. It was originally planned by General Erich Ludendorff as Operation George but was reduced to Operation Georgette, with the objective of capturing Ypres, forcing the British forces back to the Channel ports and out of the war. In planning, execution and effects, Georgette was similar to Operation Michael, earlier in the Spring Offensive.
The Second Battle of the Somme of 1918 was fought during the First World War on the Western Front from late August to early September, in the basin of the River Somme. It was part of a series of successful counter-offensives in response to the German Spring Offensive, after a pause for redeployment and supply.
The First Battle of the Aisne was the Allied follow-up offensive against the right wing of the German First Army and the Second Army as they retreated after the First Battle of the Marne earlier in September 1914. The Advance to the Aisne consisted of the Battle of the Marne (7–10 September) and the Battle of the Aisne (12–15 September).
The Second Battle of the Aisne was the main part of the Nivelle Offensive, a Franco-British attempt to inflict a decisive defeat on the German armies in France. The Entente strategy was to conduct offensives from north to south, beginning with an attack by the British Expeditionary Force (BEF) then the main attack by two French army groups on the Aisne. General Robert Nivelle planned the offensive in December 1916, after he replaced Joseph Joffre as Commander-in-Chief of the French Army.
The Nivelle offensive was a Franco-British operation on the Western Front in the First World War which was named after General Robert Nivelle, the commander-in-chief of the French metropolitan armies, who led the offensive. The French part of the offensive was intended to be strategically decisive by breaking through the German defences on the Aisne front within 48 hours, with casualties expected to be around 10,000 men. A preliminary attack was to be made by the French Third Army at St Quentin and the British First, Third and Fifth armies at Arras, to capture high ground and divert German reserves from the French fronts on the Aisne and in Champagne. The main offensive was to be delivered by the French on the Chemin des Dames ridge. A subsidiary attack was to be made by the Fourth Army. The final stage of the offensive was to follow the meeting of the British and French armies, having broken through the German lines, to pursue the defeated German armies towards the German frontier.
The United States campaigns in World War I began after American entry in the war in early April 1917. The American Expeditionary Force (AEF) served on the Western Front, under General John J. Pershing, and engaged in 13 official military campaigns between 1917 and 1918, for which campaign streamers were designated. The streamer uses the colors of the World War I Victory Medal ribbon which had a red center with a rainbow on each side of the center stripe and a purple edge. The double rainbow symbolizes the dawn of a new era and the calm which follows the storm.
The Fifth Battle of Ypres, also called the Advance in Flanders and the Battle of the Peaks of Flanders is an informal name used to identify a series of World War I battles in northern France and southern Belgium (Flanders) from late September to October 1918.
Denis Auguste Duchene was a French World War I general.
Bois des Buttes was a battle honour uniquely awarded to the Devonshire Regiment in memory of the actions of its 2nd Battalion on 27 May 1918, the first day of the Third Battle of the Aisne in the Great War.
The Battle of La Malmaison from 23 to 27 October, was the final French action of the 1917 campaign in the First World War, which had begun with the Nivelle Offensive. The French captured the village and fort of La Malmaison and took control of the Chemin des Dames ridge. The German 7th Army had discovered French preparations for the attack and also identified the date and time. Boehn chose to defend the front positions, rather than treat them as an advanced zone and to conduct the main defence north of the Oise–Aisne Canal. The German artillery was outnumbered three-to-one and on the front of the 14th Division, 32 German batteries were confronted by 125 French, which silenced most of the German guns before the attack. Gas from French bombardments on low-lying land near the Oise–Aisne Canal in the Ailette valley, became so dense that it was impossible to carry ammunition and supplies forward or to remove the wounded.
