Five companies embarked in February, 1799, for the continent of India, to take part in the war with the ruler of the province of _Mysore_, the celebrated Tippoo Saib, whose adoption of French counsels, and hostility to the British interests, proved his ruin. The Mysore was invaded by the British troops, under Lieut.-General (afterwards Lord) Harris, in March, 1799, and the army advanced by triumphant marches to the capital, the strong and splendid city and fortress of _Seringapatam_, which was captured by storm on the 4th of May, when Tippoo fell, mortally wounded, in the defence of the place. The capture of the capital having terminated the war in the Mysore, the five companies of the regiment afterwards returned to Ceylon. [Sidenote: 1800] From Columbo, the regiment marched, in October, 1800, to Point de Galle, where the head-quarters were stationed several months. [Sidenote: 1801] In April, 1801, the regiment embarked for the harbour, town, and fortress of Trincomalee, situate in a barren tract of country on the north-east side of the island of Ceylon, from whence detachments were sent to various posts in the interior. The centre of the island appeared to be defended against the approach of Europeans by the unhealthy climate of the district, through which it was necessary to pass to enter the inland provinces, which were governed by a native chief called the King of Candy. [Sidenote: 1802] In 1802 a treaty of peace was concluded between England and France and Holland; but the island of Ceylon was retained by the British. [Sidenote: 1803] War with France and Holland was resumed in 1803, and, at the same time, it was found necessary to commence hostilities with the Candians, inhabiting the interior of the island of Ceylon, with whom attempts had been made to establish a treaty of amity and commerce, but without success.
