In March 1784 Captain Baird was released, and in July joined his regiment at Arcot. In 1786 the _Seventy-third_ was directed to be numbered the SEVENTY-FIRST regiment. Captain Baird was promoted to the rank of major in the SEVENTY-FIRST regiment on the 5th of June 1787, and in October obtained leave of absence, when he returned to Great Britain. He was advanced to the lieut.-colonelcy of the regiment on the 8th of December 1790, and in 1791 proceeded to India, and joined the army under General the Earl Cornwallis. Lieut.-Colonel Baird commanded a brigade of sepoys, and was present at the attack of a number of droogs or hill forts; also at the siege of Seringapatam in 1791 and 1792; likewise at the storming of Tippoo’s lines and camps on the island of Seringapatam. In 1793 the Lieut.-Colonel commanded a brigade of Europeans, and was present at the siege of Pondicherry. On the 21st of August 1795, he was promoted to the brevet rank of colonel, and in October 1797 embarked at Madras with the SEVENTY-FIRST for Europe, but on arrival at the Cape of Good Hope, in January following, he was appointed brigadier-general, and placed on that staff in command of a brigade. He was promoted to the rank of major-general on the 18th of June 1798, and was removed to the staff in India. Major-General Baird sailed from the Cape of Good Hope for Madras in command of two regiments of infantry and the drafts of the twenty-eighth dragoons, and arrived at his destination in January 1799. On the 1st of February he joined the army forming at Vellore for the attack of Seringapatam, and commanded a brigade of Europeans. On the 4th of May Major-General Baird commanded the storming party with success, and, in consequence, was presented by the army, through Lieut.-General, afterwards Lord Harris, Commander-in-Chief, with Tippoo Sultan’s state sword, and a dress sword from the field officers serving under his immediate command. In 1800 he was removed to the Bengal staff, and on the 9th of May of that year was appointed colonel-commandant of the fifty-fourth, and colonel of that regiment on the 8th of May 1801, in which year he was appointed to command the forces which were sent from India to Egypt, and arrived at Cosseir in June, afterwards crossed the desert, and embarked on the Nile, arriving in the following month at Grand Cairo. He joined the army under Lieut.-General Sir John Hutchinson, afterwards the Earl of Donoughmore, a few days before the surrender of Alexandria, which capitulated on the 2d of September, and terminated the campaign in Egypt.
