context_page_description: The Hundred Days Offensive was a series of massive Allied offensives which ended the First World War. Beginning with the Battle of Amiens on the Western Front, the Allies pushed the Central Powers back, undoing their gains from the Spring Offensive. The Germans retreated to the Hindenburg Line, but the Allies broke through the line with a series of victories, starting with the Battle of St Quentin Canal on 29 September. The offensive, together with a revolution breaking out in Germany, led to the Armistice of 11 November 1918 which ended the war with an Allied victory. The term "Hundred Days Offensive" does not refer to a battle or strategy, but rather the rapid series of Allied victories against which the German armies had no reply.
context_section_description: With the front line broken, a number of battles took place as the Allies forced the Germans back to the Hindenburg Line. East of Amiens (after the Battle of Amiens), with artillery brought forward and munitions replenished, the Fourth Army also resumed its advance, with the Australian Corps crossing the Somme River on the night of 31 August, breaking the German lines during the Battle of Mont Saint-Quentin. On 26 August, to the north of the Somme, the First Army widened the attack by another 7 mi (11 km) with the Second Battle of Arras of 1918, which includes the Battle of the Scarpe (1918) (26 August) and the Battle of Drocourt-Queant Line (2 September).
  South of the BEF, the French First Army approached the Hindenburg Line on the outskirts of St. Quentin during the Battle of Savy-Dallon (10 September), and the French Tenth Army approached the Hindenburg Line near Laon during the Battle of Vauxaillon (14 September).  The British Fourth Army approached the Hindenburg Line along the St Quentin Canal, during the Battle of Épehy (18 September). By 2 September, the Germans had been forced back close to the Hindenburg Line from which they had launched their offensive in the spring.
