The Battle of Soissons (1918) (also known as the Battle of the Soissonnais and of the Ourcq (French: Bataille du Soissoinais et de L'Ourcq)) was fought on the Western Front during World War I. Waged from 18 to 22 July 1918 between the French (with American and British assistance) and the German armies, the battle was part of the much larger Allied Aisne-Marne counter-offensive, and followed the final German Spring Offensive, Operation Marneschutz-Reims (also known as the Friedensturm or peace offensive). The primary objective of the attack was to cut both the Soissons – Château-Thierry road and the railroad running south from Soissons to Château-Thierry. As these were the main supply routes for the German forces in the Marne salient, cutting them would severely impair the Germans' ability to supply its armies defending it, forcing them to retreat and give up their gains. This battle marked the turning point of the war as the Germans would be on the defensive for the remainder of the conflict.
