The regiment was detached from Cudalore, with other troops amounting to about fifteen thousand men, under the command of Colonel Fullerton, and, marching southward, was employed in reducing to obedience several refractory chiefs. The colonel afterwards purposed penetrating the country of Mysore, and advancing upon Seringapatam; but he halted during the armistice with Tippoo Saib. Negociations for peace having been broken off, and hostilities resumed, Colonel Fullerton pursued his original design of penetrating into the Mysore, and he resolved to take the fortress of _Palacatcherry_, which commanded a pass between the coasts, and secured a communication with a great extent of fertile country. This place he designed to occupy as an intermediate magazine, and a stronghold upon which to retreat in case of a repulse. During the march the army encountered much difficulty from woods and heavy rains, and a detachment under Captain Hon. Thomas Maitland of the SEVENTY-EIGHTH (now SEVENTY-SECOND) Highlanders performed valuable service by acting on the flanks, and preserving a communication through thick woods and a broken country. After taking several small forts, the army arrived, on the 4th of November, before Palacatcherry, and on the 13th two batteries opened their fire against the works. At night a heavy storm of wind and rain occasioned the Mysoreans to take shelter, and leave the covered way exposed, when Captain Hon. Thomas Maitland of the regiment dashed forward with his flanking corps, surprised and overpowered the Mysoreans, who fled into the fortress, leaving the first gateway open. Captain Maitland pursued, but was stopped at the second gateway; but he defended the post he had captured until additional troops arrived; and the garrison, becoming alarmed at the apprehension of a general assault, surrendered a fortress capable of a long defence under more resolute troops. After this success the army marched to _Coimbetore_, where it arrived on the 26th of November, and the garrison surrendered before a breach was made. Preparations were then commenced for further conquests, and the capture of Seringapatam, with the subversion of Tippoo’s power, was in full view; but at the moment when arrangements were made for an advance, the commissioners appointed to treat with Tippoo, sent orders for a retrograde movement.
