After returning from France in 1814, the Legion was received by Prussia, where collaborators were viewed critically, and so on 2 June 1814 it was renamed the German Legion.
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.
