The conscript units suffered high losses in the 1814 campaign (Napoleon said at the time "the Young Guard melts") and a reorganisation of the remnants of units was made on 12 March. By this time Napoleon's armies were too weak to resist the Sixth Coalition's invasion. Paris fell on 30–31 March and Napoleon retreated to Fontainebleau where he agreed to abdicate on 13 April, bringing the war to a close.
