The definitive end of the Polish Legions came with the conclusion of Napoleon's career and the abolition of the Duchy of Warsaw. The Duchy was occupied by Prussian and Russian troops following Napoleon's retreat from Russia. The Polish troops remained loyal to him until the bitter end, with Polish units holding their ground at his last battles at Leipzig (15–19 October 1813) and Hanau (30–31 October 1813), where they sustained major losses. The Legion was recreated at Sedan in early 1814, and fought at Soissons, Reims, Arcis-sur-Aube and St-Dizier. After Napoleon's defeat in the War of the Sixth Coalition, when Napoleon was forced into exile on Elba, the only unit he was allowed to keep as guards were the Polish Lancers. While many Poles returned to the Polish territories, a unit of about 325 men under Colonel Golaszewski fought in Napoleon's final 1815 campaign, the "Hundred Days", participating in the Battle of Waterloo. After Napoleon's second and final defeat, some are said to have accompanied him to his exile on Saint Helena.
