1796
The regiment continued to be actively employed until the whole of the Dutch settlements in Ceylon were reduced, which was accomplished in February, 1796, when the governor, John Geraud Van Angelbeck, surrendered the fortress of Colombo to the British arms. The people in the interior of the island had not been deprived of their independence by the Dutch, and they were not interfered with by the British so long as they preserved a peaceful demeanour.
Major-General Gerard Lake was removed from the colonelcy of the fifty-third to that of the SEVENTY-THIRD regiment on the 2nd of November, 1796, in succession to Lieut.-General Sir William Medows, K.B., who was appointed colonel of the seventh dragoon guards.
1797
In April 1797, the regiment proceeded from Colombo to Point Pedro, in Ceylon, and shortly afterwards embarked for Madras. It was removed from Fort St. George to Wallajahbad in October, but returned to Fort St. George in January, 1798.
1798
The regiment proceeded from Fort St. George to Poonamallee in September, 1798, and continued at that station during the remainder of the year.
The reduction of the power and resources of Tippoo Saib, effected by the treaty of Seringapatam in 1792, had weakened, but not extinguished, the evils consequent on his inveterate hatred of the British. The Sultan had entered into a negociation with the Governor of the Isle of France in 1798, and sent an embassy to Zemaun Shah, sovereign of Cabool, for the purpose of exciting him to an attack on the British possessions. Having also derived encouragement from the successes of Napoleon Bonaparte in Egypt, from which country the French Directory intended to act against the British dominions in India, Tippoo commenced augmenting his military force, and his hostile designs became every day more apparent. The Governor-General the Earl of Mornington (afterwards the Marquis Wellesley), seeing a rupture inevitable, resolved to anticipate the attack, and ordered the British army to take the field, and march into the heart of the dominions of the Sultan Tippoo Saib.
1799
In conformity to these orders, Major-General George (afterwards Lord) Harris, who was serving with the local rank of lieut.-general, advanced with the army under his command, on the 11th of February, 1799, and entered the Mysore territory on the 5th of March. The SEVENTY-THIRD formed part of the second brigade under Colonel John Coape Sherbroke, Lieut.-Colonel of the thirty-third regiment.
