Hundred Days Offensive

The Hundred Days Offensive was an offensive launched by the Entente/Allied Powers that finally ended World War I. Beginning with the Second Battles of the Amiens in August 8th, 1918 and continued all the way into Belgium and pushed German Empireball back and reversed his gains made from the Spring Offensive earlier on. The offensive ended with the collapse of the Hindenburg Line and the signing of the armistice on November 11th, 1918. The actual term doesn't refer to a strategy but a rapid series of Allied attacks and victories that German Empireball didn't have a reply to.
