The major European adversaries who fought World War I began by following offensive plans designed to win victory quickly, but all these failed. The war became one of grinding attrition, and by 1918, the European adversaries were exhausted. That year, the desperate Germans launched one last offensive to win the war on the Western Front, but it stalled. After the Allies drove the Germans back, fighting ended with the Armistice of November 11. This armistice was a German surrender in all but name. It disarmed German forces, demanded immediate withdrawal from all conquered territory, and imposed an Allied occupation of Germany west of the Rhine. The Treaty of Versailles elaborated the details, imposing staggering war reparations and German acceptance of guilt for the war itself. Much of the German population believed that German forces had not been defeated in battle, instead blaming German liberal politicians and Jews for undermining the war effort. This misconception contributed to the onset of World War II. World War I was the first war in which belligerents adhered to the Hague Conventions concerning the treatment of prisoners of war. There were abuses, but nothing like those that occurred in World War II.
