1757
In 1757 the regiment was formed in brigade with the Forty-third, Forty-eighth, and fourth battalion of the Sixtieth, under Major-General Lord Charles Hay, with the view of being employed in the attack of Louisburg, the capital of the French island of Cape Breton, situate in the Gulf of St. Lawrence; but the expedition was deferred until the following year, and the regiment was stationed in Nova Scotia during the winter. Major-General O'Farrell died in the summer of this year, and the colonelcy of the regiment was conferred on Brigadier-General Edward Whitmore, from the lieut.-colonelcy of the Thirty-sixth regiment.
1758
Embarking from Halifax, in May, 1758, under the command of Lieut.-Colonel Andrew Lord Rollo, the regiment proceeded with the expedition commanded by Lieut.-General (afterwards Lord) Amherst, and a landing was effected on the island of Cape Breton, on the 8th of June, when the British troops evinced great gallantry. The TWENTY-SECOND had Lieutenants Pierce Butler, John Jermyn, and William Hamilton wounded; also several private soldiers killed and wounded.[6]
The siege of Louisburg, the capital of the island, was afterwards commenced; and in carrying on the approaches the troops underwent great fatigue with cheerful alacrity. By their perseverance, and the co-operation of the fleet, the town was taken in July, and two other islands in the Gulf were surrendered. The troops received the thanks of Parliament, and the approbation of the Sovereign, for their conduct on this occasion.
1759
During the year 1759 the TWENTY-SECOND regiment was stationed at Louisburg. Major-General James Wolfe proceeded up the river St. Lawrence, with a small armament,[7] and Quebec was captured; but the nation sustained the loss of Major-General Wolfe, who was killed in the battle on the heights of Abraham, in front of Quebec, on the 13th of September, 1759.
1760
In the spring of 1760 the TWENTY-SECOND and Fortieth regiments proceeded from Louisburg, under Colonel Lord Rollo, of the TWENTY-SECOND, up the river St. Lawrence, to Quebec, from whence they advanced upon Montreal, with the troops under Brigadier-General the Honorable James Murray. The French possessions in Canada were invaded at three points, and the Governor concentrated his forces at Montreal; but he was unable to withstand the valour and discipline of British troops, commanded by officers of talent and experience; he therefore surrendered Montreal, and with it all Canada, the French battalions becoming prisoners of war. The TWENTY-SECOND had thus the honor of taking part in the conquest of the two fine provinces of Upper and Lower Canada, which have since continued to form part of the possessions of the British Crown.
