Bundlecund still continued the seat of war; Gopal Sing, availing himself of the natural fastnesses of the country, evaded our troops continually. He was overtaken near Perereea in February (and Lieutenant Timbrell is mentioned on this occasion), but escaping, he fled to the hills, from whence he came out the following month, and before assistance could be sent, burned the cantonment of Tiroha, maintaining a harassing and desultory warfare, which, without producing any marked events, kept the troops constantly on the move during that and the following year; and it was only brought to a close by the siege of Callingur, in February, 1812; after which, Gopal Sing returned to his allegiance. Callingur is a fort situated on one of those detached rocky eminences abounding in Bundlecund, and which require little aid from art, as they are almost natural fortifications. The rock at the summit forms a natural scarp, of from ten to twenty feet high, and the whole side of the hill is very difficult of access. The only entrance is in the centre of the northern wall, and the approach to it is by a steep pathway winding up the face of the hill; this gained, a succession of gates bar the entrance to the fort. The force under Colonel Martindell assembled on the 19th January; on the 21st occupied a small hill, within 800 yards, which promised to be the most favourable point for attack. The 22nd, 23rd, and 24th were employed in clearing the jungle and making a road for the guns, and, on the 25th, two 18–pounders were, with great labour, got up. In the night, two more guns and two mortars followed, and were placed in battery: two other batteries were erected at the foot of the hill, against the main gateway, and the whole being ready by the 28th, opened with great effect. The enemy’s guns were immediately dismounted, and the bastion opposed to the guns on the hill demolished. The town was taken this day; and the batteries continuing to play till the 2nd of February, the breach was supposed practicable, and a party advanced to storm it, but finding a perpendicular ascent of twenty feet, their ladders crushed and broken by the showers of large stones the enemy rolled down, the party were forced to retire with heavy loss: the killadar, however, was glad to come to terms, and capitulated on the 8th February. Major Fuller commanded the artillery in this siege, and their exertions were acknowledged in General Orders:—“The Governor-General deems it his duty to express his concurrence in the honourable testimony borne to the distinguished services of the artillery and engineer departments by Colonel Martindell.”
