In July 1813, the British advanced to Pyrenees. Most of the French army retreated back to France to be organized by Soult. Soult launched 2 assaults on Spain on 25 July. After marching between Pamplona and Mt Achiola the regiment, with the Inglis's brigade, attacked the French on a hill near Urroz. With the help of Chasseurs Britanniques, they pushed the French from the hill. On 2 August, the 7th Division, with the 4th and part of the Light Division, attacked the weak centre of the remains of Soult's Corps. At the end of the month, Soult tried to take back San Sebastian. When they learned of the failure of the main attack, the French retired.
