A complete change had been achieved in the aspect of affairs beyond the Indus; the chiefs of Cabool and Candahar, who had entertained hostile designs against the British interest, had been deprived of power, and the territories they ruled had been restored to a friendly monarch. These splendid results accomplished, part of the army was withdrawn from the country; but the THIRTEENTH Light Infantry were selected to remain in Affghanistan, to support the government of the restored Shah, against the machinations of the chiefs who had usurped his authority during his exile. The regiment was encamped near Cabool until November, when it marched into garrison at the Bala Hissar, or citadel of Cabool, in which stands the palace, with the thirty-fifth native infantry, and a detail of artillery, and remained there during the winter, which was an unusually severe season. Brigadier Dennie commanded the garrison, and Lieutenant Hamlet C. Wade, who had been selected by Lieut.-General Lord Keane to serve on the general staff of the army, was appointed major of brigade to this force. [Sidenote: 1840] In May, the regiment moved into camp much reduced in numbers, having suffered very severely from disease. On the 24th September it was again called upon to take the field, having been attached to the force, under Sir Robert Sale, directed against Dost Mahomed in the Kohistan of Cabool; and it marched that day. On the 29th September, the regiment under Lieut.-Colonel Tronson assisted in carrying the town and forts of _Tootumdurra_, at the entrance of the Ghorebund Pass, occupied by Ali Khan, a refractory chief of the Kohistan. The loss of the THIRTEENTH was limited to two privates wounded; one mortally.
