On the 31st of March part of the Bengal army, consisting of 2,200 native troops, with 22 pieces of heavy ordnance, commanded by Brigadier-General Watson, joined the besieging force; and these guns were soon placed in battery, and opened on the fort. The storm of war now raged round _Asseerghur_ with awful fury; the shot and shells from the numerous British batteries flew in showers, a dozen shells sometimes exploding within the area of the upper fort at the same moment, and a breach was soon effected in the outer retaining wall at the only assailable part of the fort; at the same time two batteries of 18 and 24-pounders were directed against the inner wall. This unremitting fire was continued until the 6th of April, when the garrison, apprehending the consequences of having to sustain an attack on the works by storm, forced the Killedar to sue for terms, namely, "liberty to preserve their arms and to depart with their personal property." These conditions being refused, hostilities recommenced; the Killedar, however, accepted the terms offered on the 8th, and agreed on his part to surrender the fort on the morning of the 9th, and the firing ceased; but, as he said he could not answer for the garrison, the control of which he had lost, preparations were made for renewing operations in case of refusal. The garrison, however, submitted; a British guard took possession of the gates at the appointed hour; and a union flag was sent, with an escort of 100 Europeans and the like number of native infantry, to the upper fort, and hoisted under a royal salute from all the batteries. The garrison, amounting to 1200 men, marched out at noon and grounded their arms. Their loss was inconsiderable, from having such good cover from the fire of the British batteries, being only 43 killed, and 95 wounded; and this was chiefly occasioned by the bursting of shells. The loss of the besieging army was 11 European and 4 native officers, and 95 European and 213 native soldiers killed and wounded, including the loss at the explosion of the magazine on the 21st of March. Of this number the ROYAL SCOTS had only 7 rank and file killed and wounded in addition to the loss on the 18th of March. The force employed against Asseerghur amounted to about 20,000 men; the ordnance of all calibre to 61 guns and 40 mortars and howitzers: the enemy had 119 guns and mortars mounted on the works, and some of the guns were of immense calibre--one a 384-pounder.[137] In a general order, dated Madras, 28th April, 1819, the conduct of the five companies of the regiment was spoken of in the following terms:-- "The conduct of the detachment of His Majesty's ROYAL SCOTS under the command of Captain Wetherall, and of His Majesty's 30th Foot, under Major Dalrymple, during the siege of Asseer, has been most exemplary, and such as to reflect the most distinguished credit on their several commanding officers, as well as on the whole of the officers and men composing those detachments."
