Tochi Valley, (also known as Dawar), is one of the main routes into Afghanistan from the Khyber-Pakhtunkhwa of Pakistan.
The Tochi Valley leads from Bannu District through tribal areas, and is inhabited by the Dawari tribe. The valley is divided into two parts, known as Upper and Lower Dawar, by a narrow pass called the Taghrai Tangi, some three miles long. Between Dawar and Bannu is the low range of uninhabited hills, which skirt the Bannu district. It was by this route that Mahmud of Ghazni effected several of his raids into India and the remains of a road flanking the valley and of defensive positions can still be traced. After the Waziristan Expedition of 1894, the Tochi was garrisoned by British troops; but when Lord Curzon reorganized the frontier in 1901, the British troops were withdrawn, and their place supplied by tribal militia. The chief posts are Saidgi, Idak, Miranshah, Datta Khel and Sheranni. The valley was the scene of action for the Tochi or Dawari Expedition under Brigadier-General Keyes in 1872, and the Tochi Expedition under General Corrie Bird in 1897. Tochi Valley is also one of the few places where inscriptions of the Bactrian language have been found.[1]
