The insurrection in the Canadas, headed by Papineau, induced the Government to send a company to that colony. Captain Colin Mackenzie with one sergeant and thirty-seven rank and file went out in the ‘Hastings,’ seventy-four, as a guard of honour to Lord Durham when his lordship was appointed Governor-General in Canada. The remainder, three sergeants and forty-five rank and file, sailed in the steamer ‘Dee.’ The guard of honour landed at Quebec on the 29th May, and the ‘Dee’ detachment on the 14th June. A proportionate quantity of intrenching tools and engineer stores were landed with the company. At the celebration of Her Majesty’s coronation on the plains of Abraham in June, 1838, the Earl of Durham minutely inspected the company, and in the presence of several general officers, noticed the steadiness with which the company marched past. This expression the Governor-General repeated at the chateau of St. Louis on the 28th June, and added, that the soldier-like appearance of the sappers and their steadiness under arms exceeded his expectations. The good conduct of the company also elicited his lordship’s approbation. While at Niagara, on the 11th September, the company was reviewed by Major-General Sir George Arthur, with the King’s dragoon guards and 43rd regiment, and his Excellency spoke in praise of the appearance of the company, its marching and manœuvring. Soon after, the head-quarters of the company were removed to the Niagara frontier to place it in a state of defence. The work of reparation commenced with Fort Mississaqua. About this time twelve non-commissioned officers and men were removed, for engineer services, to Amherstburg, and another party of twenty-two of all ranks was detached to Montreal. The latter was detained at Cornwall for a few days by Major Phillpotts of the corps, and, under Lieutenant Roberts, formed the advanced guard with a detachment of the 71st light infantry, in a successful attack on the rebels at Beauharnois on the 10th November, 1838. The good conduct of this party was acknowledged by Colonel Carmichael who commanded the attack.
