On the 31st of December, 1844, a wing of the regiment arrived at Susseedroog from Kolapore, and joined the first brigade of the Field Force in the Sawunt-Warree country, and was employed in investing the forts of Monuhurr and Monsentosh, and participated in all the operations for driving the enemy out of their stockades in the densely wooded country between Susseedroog and the Forts. [Sidenote: 1845] The regiment had several skirmishes with the enemy; on the 17th of January, 1845, part of the wing descended the Elephant rock with other troops, and took the village of Seevapore, in the Concan, close under Fort Monuhurr, where one man was killed and seven wounded. The whole of the soldiers were employed, part in the Deccan or heights above, and part in the Concan close under the forts, investing them from the 17th to the 26th of January, during which period the forts were constantly shelled by the British artillery, the enemy from the forts firing their great guns and musketry. On the night of the 26th of January the enemy vacated the forts unperceived, and escaped through a dense jungle, leaving the forts in the possession of the Anglo-Indian army. The wing joined the regiment at Kolapore on the 6th of February, escorting prisoners taken during the insurrection. The regiment was employed in doing duty over about six hundred prisoners until its recall to Poonah, for which place it marched on the 16th of April, and arrived on the 2nd of May, 1845. A wing of the regiment, consisting of four hundred rank and file, under the command of Captain Souter, marched from Poonah for Bombay on the 25th of December, 1845. [Sidenote: 1846] The head-quarters of the regiment, under the command of Lieutenant-Colonel Samuel Brandram Boileau, consisting of five companies, marched from Poonah to Bombay on the 15th of August, 1846, and joined the wing of the TWENTY-SECOND at that station. The march was performed in the middle of the monsoon, in eight days, rain consequently falling nearly the whole of the way. The regiment remained together at Bombay, having six companies at Colaba, and three at Fort George, until the 14th of November, 1846, when the head-quarters, with five of the companies which were stationed at Colaba, were ordered to Poonah, in consequence of fever of a malarious nature having attacked the men, nearly every soldier at Colaba having been admitted into hospital in less than two months; the casualties were very numerous. [Sidenote: 1847] [Sidenote: 1848] The left wing, consisting of four companies, marched from Bombay on the 12th of January, 1847, and arrived at Poonah on the 21st of January. During the year 1848 the regiment continued to be stationed at Poonah. [Sidenote: 1849] On the 25th of January, 1849, the regiment proceeded to Bombay, and was subsequently stationed at Colaba. The left wing, consisting of four companies, embarked for Kurrachee on the 24th of January.
