In May, 1843, the regiment was ordered to Khytul, and formed part of a force under Major-General Fast, which was sent to reduce the city and state of Khytul to British subjection. The force arrived at Khytul after about a week’s march, and the enemy, after a slight show of resistance, evacuated the city, which was occupied by the British troops. All the objects of the expedition having been fulfilled, the regiment returned to its cantonments at Umballa. All, however, remained under canvas, exposed to most intense heat, until July, 1843, when the men were housed, and a few of the officers got shelter. In October, 1843, an outbreak occurred at Lahore, and the Maharajah, Shere Singh, was shot at a review by his brother-in-law, Ajeet Singh; after this event the youthful Dhuleep Singh, a reputed son of the late Runjeet Singh, was placed on the throne. The THIRTY-FIRST regiment was in consequence ordered to the frontier, and marched for Ferozepore on the 16th of November, where it arrived on the 1st of December, 1843, and remained as a corps of observation. [Sidenote: 1844] The THIRTY-FIRST, commanded by Colonel Bolton, C.B., continued at Ferozepore, where the regiment was joined by ninety-three recruits from England. On the 16th of January, 1844, the regiment was inspected, and elicited great praise from Major-General Hunter of the Company’s Service, and again on the 16th of February, by Major-General Sir Robert Dick, K.C.B., who expressed great praise as well of the soldierlike and gallant bearing as of the high state of discipline of the regiment. The weather becoming extremely hot, the regiment marched from Ferozepore on the 19th of April, 1844, _en route_ to Umballa, where it arrived on the 2nd of May. On the 30th of December, 1844, his Excellency General Sir Hugh Gough, Bart., Commander-in-Chief in India, inspected the THIRTY-FIRST, in review order, on which occasion he expressed himself highly satisfied with the soldierlike appearance of the regiment. [Sidenote: 1845] On the 12th of March, 1845, a detachment of recruits and volunteers, consisting of one major, one captain, three lieutenants, two ensigns, one assistant-surgeon, with four hundred and seventy-one rank and file, joined the regiment from the lower provinces, under the command of Major Spence. Many men continued to die from the effects of the Cabool campaign, but the station in itself proved healthy until July, when it was visited by cholera in a most fearful manner. On the 26th of July the regiment was ordered into camp, about two miles from the barracks, at a few hours’ notice, with orders for one officer per company, as well as the medical officers, constantly to remain in camp under Major Spence, where they continued until the 5th of August. In one month the regiment lost by cholera eighty-nine men, women, and children.
