The cavalry saw much service during the rest of the Ulm campaign. At the Battle of Haslach-Jungingen on 11 October 1805, the 15th and 17th Dragoon Regiments lost their eagles. However, the action was a French victory over a greatly superior force. Murat led his horsemen in a series of actions between 16 and 18 October before securing the surrender of General Franz von Werneck's Austrian corps. In these clashes, Klein's 1st, 2nd, 4th, 14th, 20th, and 26th Dragoon Regiments, the 1st Cuirassier Regiment, and other units were involved. At the Battle of Schöngrabern on 16 November, Klein's troopers were engaged as were the 11th, 13th, and 22nd Dragoons from Walther's division. At the Battle of Austerlitz on 2 December, Murat led approximately 7,400 cavalrymen including Nansouty's 1st Heavy Cavalry Division, Hautpoul's 2nd Heavy Cavalry Division, Walther's 2nd Dragoon Division, General François Étienne de Kellermann's light cavalry division and General Édouard Jean Baptiste Milhaud's light cavalry brigade. Beaumont's 3rd Dragoon Division was attached to the IV Corps while Bourcier's 4th Dragoon Division with 2,500 men and three guns were attached to the III Corps.
