On the 13th of September, Brigadier Dennie arrived from Cabul with reinforcements, which had been despatched on hearing of the Ameer’s advance. The force at Bamian, besides the troop, consisted now of the 35th native infantry, the Goorkah regiment, a resallah of irregular cavalry, and 400 janbaz, or Afghan horse. The Afghan infantry had been disarmed and sent to Cabul. On the 17th, in the evening, the Dost’s piquets entered the Bamian valley at Soorukdhurrah, about four miles distant, and on the following morning the brigadier having received information which led him to believe that merely the advanced guard of the enemy had arrived, took out a small detachment of only eight companies, and engaged the whole Usbeg force, who were completely routed and driven from the field in great confusion. Two guns of the troop, under Lieutenant Mackenzie, were present in this affair. The Usbegs fell back almost immediately when the guns opened on them, abandoning in succession three positions in which they attempted to make a stand, but from which they were instantly dislodged by the guns advancing. Thus in the valley itself, where the main body of the enemy was, the contest was decided by the horse-artillery, but on the heights the infantry were engaged with some other parties of the enemy, mostly foot-men. The cavalry pursued the Usbegs for some miles up the defile of Soorukdhurrah. The enemy has been variously computed at from 5,000 to 10,000 men in the field. Four guns of the troop accompanied Brigadier Dennie in his subsequent pursuit of the enemy, but the movements of the Usbegs had been too rapid to allow it to be effectual; but the results were most happy, as it induced the Ameer to leave the Usbeg camp, and forced the Wallee to abandon his cause. The rest is well known: the Dost threw himself into the Kohistan of Cabul, and the theatre of war being thus changed, the British troops were recalled from Bamian, and on the 8th October (exactly a year and a day after its arrival), the troop marched in progress to Cabul with Colonel Dennie. At the commencement of the following year the troop returned to India with the escort in charge of the captive Ameer. In the expedition to the Kohistan, under Brigadier Sale, Captain A. Abbott and his battery, and Lieutenant Warburton with two of the Shah’s bodyguard guns, were employed. The fort of Tootundurra was carried with little loss, a fact attributed “in a great measure to the dread inspired by the excellent practice of the artillery under the able direction of Captain Abbott, assisted by Lieutenants Maule and Warburton.” In breaching Julga in October, these same guns were again employed, and Captain A. Abbott and Lieutenant Warburton are reported as having distinguished themselves in the service of the artillery.
