The repercussions of the revolt at Meerut and Delhi were soon felt at Peshawar, on the North-West Frontier of India. The regiments of Purbiah Sepoys stationed there were suspected of disloyalty and four of them were disarmed on 22 May 1857. At Mardan, the men of the 55th Native Infantry revolted and fled towards Swat. They were pursued by John Nicholson and forty of the Sepoys, out of those who were captured were blown from guns on 11 June at the parade ground of Peshawar. On 28 August the disarmed 51st Native Infantry revolted. Of the 870 men of this Regiment only about 70 survived. Those who were captured were tried by a court-martial and executed at Peshawar.
