The regiment entered Haguenau on 2 August, then Reichshoffen, where it fought in the Battle of Wörth. There it took part in the great cavalry charge. The remains of the regiment withdrew in good order and arrived at Saverne on 7 August and after a short period of recovery there joined the "Army of Châlons" on 20 August 1870. After passing through Floing the regiment took part in the Battle of Sedan on 1 September. Together with the rest of its division, the regiment then became prisoners of the Prussian army.
