In 1851 two officers of the British Customs department in a place called Tanawal were killed. The British believed they were killed by the Hasanzai sept of the Yusufzai tribe, so the British then sent an army led by Colonel Mackeson, which destroyed a number of tribal strongholds. In 1868 the Yusufzai helped by the Khan of Agror, who was upset that the British had set up a police post at Oghi in the Agror valley, attacked that post with many men. But he was forced to move back.
