The Battle of Epoy (9-12 July 1918) occurred when the Entente powers launched an offensive against the Imperial German Army in the Champagne region of northern France in the final months of World War I. The Allied troops, consisting of troops from France, Britain, Canada, and other countries, took part in an assault on the German forces at Epoy in Champagne, engaging them in trench warfare. The Germans repelled the French assaults on their trenches with sniper fire, and the French were picked off in droves as they advanced through the open. On 12 July 1918, the offensive ground to a halt after the failure of several Allied attacks.
