Reinforced with elements of 7th Regiment of Light Horse Lancers, the 2nd Regiment of Light Horse Lancers was renamed Queen's Regiment of Lancers "(Régiment Lanciers de La Reine)". After the Bourbons returned to France, the 2nd Regiment of Light Horse Lancers was reintegrated into the 3rd Dragoon Regiment. Then, Napoleon returned from exile and the 2nd Regiment of Light Horse Lancers was the title again. Serving the Belgian Campaign, they fought at the Battle of Waterloo, but were repulsed.
