The army advanced out of the fortress in March, and the 83rd was involved in a number of the skirmishes fought with the retreating French army through the spring of 1811. In May, it fought at the Battle of Fuentes d'Onor, where its defence of the village was mentioned in Wellington's despatches, and the regiment was awarded Fuentes d'Onor as a battle honour. It was then deployed at the siege of Badajoz and the siege of Ciudad Rodrigo, where on 25 September it helped drive off a large French relief force. The siege of Ciudad Rodrigo ended when the fortress was stormed on 19 January 1812. The light company of the 83rd led the attack on the right flank, while the main body of the battalion provided covering fire for the central attack. The battalion lost four dead and fourteen wounded, and was awarded the battle honour Ciudad Rodrigo.
