During these occurrences the battalion companies of the Fifty-second, Seventy-first, and Seventy-second Regiments forced their way across the river to the island, overpowering all that opposed them, when Captain Archdeacon, commanding a battalion of Bengal sepoys, being killed, that battalion was thrown into confusion, falling back upon the Seventy-first. Major Stair Park Dalrymple, wishing to prevent the sepoys intermingling with his men, ordered the regiment to move obliquely to the left, an operation that by chance brought him in contact with the Sultan’s redoubt, which was instantly attacked and carried. The charge of the redoubt was given to Captain Hugh Sibbald, of the Seventy-first, with his company, who on the following morning was killed, nobly defending it against repeated and desperate attacks from the enemy. He was replaced by Major Shelly, under whom the redoubt sustained two serious assaults. The Commander-in-Chief, General the Earl Cornwallis, in compliment to the memory of this officer, had the name of the redoubt changed to “Sibbald.” In the evening of the 7th of February 3,000 of the enemy’s horse attacked the British troops on the island, but were repulsed by the Seventy-first Regiment and the First Coast Sepoys. In the course of these operations the regiment had Captain Sibbald and Lieutenant Daniel Bayne killed; Ensign Duncan Mackenzie was wounded; about 100 rank and file were killed and wounded. The enemy’s loss was very severe, being estimated at 20,000 _hors de combat_. Eighty pieces of cannon were taken by the British. The following general order was issued:— “Feb. 7th. “The conduct and valour of the officers and soldiers of this army have often merited Lord Cornwallis’s encomiums, but the zeal and gallantry which were so successfully displayed last night in the attacks of the enemy’s whole army in a position which had cost him so much time and labour to fortify, can never be sufficiently praised; and his satisfaction on an occasion which promised to be attended with the most substantial advantages has been greatly heightened by learning from the Commanding officers of divisions that this meritorious behaviour was universal through all ranks, to a degree that has been rarely equalled. Lord Cornwallis therefore requests that the army in general will accept of his most cordial thanks for the noble and gallant manner in which they have executed the plan of the attack; it covers them with honour, and will ever command his warmest sentiments of admiration.” On the 9th of February the army took up its final position for the siege of Seringapatam, and on the 15th Major-General Robert Abercromby joined with the Bombay force, consisting of the Seventy-third, Seventy-fifth, and Seventy-seventh regiments, besides native troops, making a total of about 6,000 men.
