The regiment joined in the German Campaign of 1813. It fought in the siege of Königsberg, the Battle of Leipzig of 16–19 October, and the Battle of Hanau of 30–31 October. In late 1813 it was assigned to the French corps d'observation in Bavaria, and then the V Corps when the corps was sent to reinforce the garrison of Danzig, then under a siege by a Russo-Prussian army. During the Campaign of France in early 1814, the 2nd Dragoon Regiment fought in an action at Rambervillers, at the Battle of Brienne on 29 January, and at the Battle of Saint-Dizier on 26 March. That year, the regiment incorporated 25 survivors from the "Compagnie des Guides-interprètes" (the predecessors of the later French corps of "Interprètes Militaires" or military interpreters), which was first formed at Boulogne in 1803 in preparation for Napoleon's planned invasion of the United Kingdom.
