The troops destined for the final capture of Seringapatam were placed under the command of General Harris, the Commander-in-Chief at Madras. All three Presidencies were represented.
The cavalry division was under Major-General Floyd (an officer well versed in Indian warfare), who had commanded the 19th Hussars in the previous capture of the fortress in 1792. It consisted of the 19th and 25th Light Dragoons and four regiments of Madras cavalry, organized in two brigades, each consisting of one British and two native regiments.
The Madras Column was distributed in three brigades, one composed entirely of British regiments—the 12th (Suffolks), 74th (Highland Light Infantry), and the Scots Brigade (now 2nd Connaught Rangers). Major-General David Baird was in command of this brigade. The six regiments of Madras sepoys were formed in two brigades, under Colonels Gowdie and Roberts, of the Company's service, the Madras Division being under Major-General Bridges, an officer of the Company's service.
The Bengal Column was commanded by Major-General Popham, a Company's officer, and consisted of three brigades. The First, under Colonel Sherbrooke, comprised the 73rd (Royal Highlanders) and a regiment of Swiss mercenaries (de Meurons); the Second Brigade was made up of three battalions of Bengal sepoys, under Colonel Gardiner; and the Third Brigade was composed of three battalions of Madras sepoys, under Colonel Scott, of the Scots Brigade.
The Bombay Column was commanded by General J. Stuart, and consisted of the 75th (Gordon Highlanders), the 77th (Middlesex), and the 1st Bombay Europeans (now the Royal Dublin Fusiliers), under Colonel Dunlop, with six battalions of Bombay sepoys in two brigades, under Colonels Montresor and Wiseman. A fourth column was under the command of Colonel Arthur Wellesley, and comprised two regiments of Bengal and four of Madras infantry, with his own regiment, the 33rd Foot (West Riding Regiment), to stiffen the whole. Wellesley also was given the supervision of the Nizam's troops, numbering some 6,000 irregular cavalry and 3,000 infantry, trained and organized by French officers. In round numbers, the force at General Harris's disposal numbered 7,000 British and 27,000 native troops, with a well-equipped siege-train of forty-seven pieces of heavy ordnance.
Early in February the Commander-in-Chief received his final orders to advance from Madras, and on April 14 he joined hands with Stuart's column in the immediate vicinity of Seringapatam. Three days afterwards the siege commenced, and on May 3 the breach was declared practicable. Baird claimed the privilege of leading the stormers (a privilege his by right). He had been a prisoner in the fortress for over four years as a young Captain, and he had been present in command of a brigade of Madras sepoys at Cornwallis's capture of the fortress seven years before. Taking into consideration the strength of the work and the immense numerical superiority of the enemy, the fortress was carried with marvellously slight loss, the killed numbering 69 English and but 12 sepoys, the wounded 248 and 32 respectively, that of the Mysoreans being estimated at 1,000 killed alone. The total casualties during the siege, however, testified to the stubborn stand made prior to the assault, as the following figures show:
