1810
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.
1811
After the capture of the Mauritius, the regiment was stationed a short time at that island, and in January it sent a detachment of five officers and seventy men to Tamatave, in the Island of Madagascar. In March and April the regiment was removed to the island of Bourbon, where it was joined by the survivors of the detachment from Madagascar, reduced in number, by disease, to two officers and twenty-five men: they had been made prisoners by the enemy, and re-captured by the British ships of war.

1813
In July, 1812, the regiment returned to the Mauritius; but again proceeded to Bourbon, in August, and was removed to the Mauritius a second time in May, 1813.
1814
1815
A number of men having volunteered from the militia to the TWENTY-SECOND regiment, His Royal Highness the Prince Regent was pleased to approve of a second battalion being formed, and it was placed on the establishment of the army on the 10th of February, 1814. The war in Europe being terminated soon afterwards, by the abdication of Napoleon Bonaparte, and the restoration of the Bourbon dynasty to the throne of France, the second battalion was disbanded at Chester, on the 24th of October, transferring the men fit for duty to the first battalion, which they joined at the Mauritius, in April, 1815, in so good a state, as to be specially noticed in general orders, and Captain Thomas Poole, commanding the party, received the thanks of the governor.
On the 1st of June, 1815, the rifle company of the first battalion of the Twelfth regiment, together with the first battalion of the Eighty-seventh regiment, and the flank companies of the TWENTY-SECOND regiment, were formed into a field brigade, and on the 16th of June embarked from the Mauritius to join the army in Bengal. The troops arrived at Bengal on the 2nd and 3rd of August; re-embarked on the 23rd of September, and landed at the Mauritius on the 14th of November, 1815. The light company of the TWENTY-SECOND regiment, while on passage to Bengal, was wrecked in the Straits between Ceylon and the opposite continent. The conduct of the flank companies, while in India, was highly commended in general orders issued before they embarked from Fort William,—on their return to the Mauritius.
While the flank companies were thus employed, the remainder of the TWENTY-SECOND regiment was placed under canvas at Pamplemousse, seven miles from Port Louis, as it was suffering severely from a prevailing disease at the Mauritius. There being but a small force left on the island, and this reduced in numbers and efficiency by disease, a meditated insurrection had nearly attained an outbreak, but for timely information.
