Hundred Days Offensive

The Hundred Days Offensive was the final series of Allied attacks on the Western Front in the First World War. It began with a surprise attack at Amiens, where tanks, aircraft and infantry advanced well beyond the German lines, an event Erich Ludendorff called the black day of the German army. Allied forces under Marshal Ferdinand Foch, including British, French, American, Canadian, Australian and Belgian troops, then launched a series of attacks along the line. They broke through the Hindenburg Line and forced the Germans to retreat. With its army exhausted, its allies collapsing and unrest at home, Germany asked for an armistice, which took effect on the eleventh of November.
