After Napoleon's return from Elba on 26 February 1815, the soldiers of this unit were merged into the 30th and 31st infantry regiment, 8th (Russisch-Deutsche Legion) Ulanenregiment and 18th and 19th horse-artillery batteries of the Prussian army. These units took part in the Waterloo campaign, known as the Hundred Days, as part of the III Corps of the Prussian Army. Several Dutch members of the Russo-German Legion had been decorated for valour. Already in 1814, several of them were given permission to wear their medals. In 1821, the members of the Legion were awarded the Russian Service Medal for the wars of 1813–1814, and also given permission to wear this decoration.
