The
Hundred Days Offensive was the final period of the
First World War, during which the
Allies launched a series of offensives against the
Central Powers on the
Western Front from 8 August to 11 November 1918, beginning with the
Battle of Amiens. The offensive essentially pushed the Germans out of France, forcing them to retreat beyond the
Hindenburg Line, and was followed by
an armistice. The term "Hundred Days Offensive" does not refer to a specific battle or unified strategy, but rather the rapid series of Allied victories starting with the Battle of Amiens.
