With the recapture of Dehli in September 1857, British control of the Punjab became easier as the rebellion in lost its momentum. By February 1858, the situation had improved to the point where the regiment could be transferred to the North-West Frontier. The regiment was assigned to Major-General Sir Sydney Cotton's Sittana Field Force. The objective of Cotton's command was to carry out a punitive expedition against Hindustani fanatics who had been instrumental in the mutiny of a native regiment stationed near Peshawar. Crossing through the Daran pass, the regiment participated in the destruction of the stronghold at Mangal Thana. After destroying the fortifications at Mangal Thana, the expedition turned its attention to the main fanatic base at Sittana. Despite resistance from the Fanactics, the upper and lower Sittana villages were captured by the British forces, including the regiment. After burning them to the ground, Cotton's expedition returned to British India. The success of the expedition resulted in a treaty between the various tribes and the British leading to the expulsion of the Hindustani Fanatics as well as an agreement by the various tribes to resist attempts by the Fanatics to return.
