Holkar continued his resistance to the British authority, and Scindia evinced a disposition to renew hostilities. These events occasioned the regiment to quit Cawnpore, in October, to pursue the army of Holkar, who was driven from place to place, until the British troops arrived at the banks of the Hyphasis, or Sutlej, where he submitted, and a treaty of peace was concluded in December. Scindia also concluded a second treaty, and the British power and influence in India were thus augmented and consolidated.
From the banks of the Sutlej, the regiment marched to Delhi, where it arrived in February, 1806, and in March it was removed to Muttra, where it received the thanks of General Lord Lake, and of the Governor-General in Council, for its conduct during the war.
On the 30th of October, General Simcoe, who died in 1806, was succeeded in the colonelcy of the regiment by Lieut.-General Sir James Henry Craig, from the Eighty-sixth foot.
Leaving Muttra in July, 1807, the regiment proceeded to Berhampore, where it arrived on the 7th of August.
Major-General the Honorable Edward Finch was appointed colonel of the regiment on the 18th of September, 1809, from the Fifty-fourth foot, in succession to Sir James Henry Craig, K.B., removed to the Seventy-eighth Highlanders.
The regiment remained at Berhampore until August, 1810, when it embarked in boats, and proceeded to Fort William, in order to form part of the expedition against the _Mauritius_, under Major-General the Honorable J. Abercromby. A landing was effected in the bay of Mapou, on the 29th of November, without opposition, and on the following day the troops advanced towards the capital; being exposed to severe heat, and unable to procure water, the soldiers became exhausted, and arriving at the powder-mills, five miles from Port Louis, they halted near the stream. Resuming the march on the 1st of December, the troops were opposed by the enemy in force, and some sharp fighting occurred, in which the TWENTY-SECOND took part and had several men wounded. The French were driven from their ground, and they fell back upon Port Louis; the British took post in front of the position occupied by the French. Being unable to withstand the valour and discipline of the invading army, the governor, General de Caen, surrendered the island to the British arms.
