In 1815 the Nepaulese were brought to submission, and the regiment marched from the camp in the mountains to the banks of the Ganges, where it embarked in boats and proceeded down the river to Berhampore, where it landed on the 30th of August, and was joined by a strong detachment from the second battalion, under the command of Major Giles. On the 20th of October the regiment again embarked in boats, and proceeded to Calcutta, where it remained until December, when it embarked for Madras. [Sidenote: 1816] In January, 1816, the first battalion marched from Madras to Wallajahbad; but in March three companies returned to Madras, and seven proceeded to the Naggery Pass, to keep in check the plundering bands of _Pindarees_, who infested the British territory in India at this period. These marauding tribes having been driven from British India with severe loss, the seven companies marched to Bangalore, where they were joined by the detachment from Madras in June; also by a detachment from Europe. In November the battalion commenced its march for Trichinopoly, where it arrived on the 12th of December, after a march of two hundred and seven miles. [Sidenote: 1817] On the 14th of February, 1817, Lieut.-General Sir John Abercromby, G.C.B., died at Marseilles, in the south of France, at which place he had resided some time for the benefit of his health. The high military character and private virtues of this distinguished officer, with his attachment to, and the lively interest he took in every thing connected with, the FIFTY-THIRD regiment, occasioned his death to be much regretted. He was succeeded by Lieut.-General Rowland Lord Hill, G.C.B., from the ninety-fourth regiment. Colonel Mawby commanded the regiment in cantonments at Trichinopoly; and in June the flank companies were detached, under the command of Major Giles, to join a flank battalion forming at Darwah, to serve with a division of the army under Colonel Pritzler, which was called to take the field in consequence of several native chiefs having prepared to wage war against the British power in India. While the flank companies were in the field, the strength of the regiment was augmented by the detachment from the second battalion, and a number of volunteers from the eightieth regiment. [Sidenote: 1818] In 1818 the regiment sustained great loss from the cholera. [Sidenote: 1819] The flank companies were actively employed with the field force under Brigadier-General Pritzler, who reduced several fortified places to submission to the British authority, and among others the fort of _Copaul Droog_, the garrison of which place made a desperate defence. The excellent conduct of the troops employed in this service was made known in general orders dated the 22nd of June, 1819. The flank battalion led the assault of the place; and the conduct of Captain Cuppage, and Lieutenant Silver of the FIFTY-THIRD regiment, was particularly noticed. Lieutenant Silver was wounded.
