On 31 March, Pollock completed restoring the morale of the sepoys at Peshawar and forced his way through the Khyber Pass. He sent his troops up the heights on either side of the pass to outflank the defenders, and succeeded with very few casualties. He reached Jalalabad on 14 April, to find the siege already lifted. After wavering for some weeks, Sale had led a sortie by the garrison of Jalalabad on 19 February, to capture grazing sheep to replenish his supplies of food. He repeated the sortie on 7 April, defeating the besiegers and forcing them to raise the siege.
