In the month of September, 1811, Sir George Prevost arrived in Canada, and in the same month, proceeding from Quebec to the district of Montreal, he inspected the different forts and military positions in that neighbourhood, and on the American frontier. Soon after his return to Quebec in the November following, he communicated confidentially with the Adjutant-General of the forces in England, upon the apprehended hostilities with America. In December he proposed to Lord Liverpool, then Secretary of State for the Colonies, the raising a corps of Fencibles, from the Glengarry settlement in Upper Canada; and in his correspondence with Admiral Sawyer, who commanded on the Halifax station, he requested that a ship of war might be sent, on the opening of the navigation, to the St. Lawrence. In the month of February, 1812, another communication was made to the Secretary of State's Office, in which Sir George Prevost expressed a hope, that the proceedings in Washington would justify him, in making preparations to repel the threatened attack. Those preparations had been commenced as early as November, 1811, by forwarding arms and ammunition to the Upper Province. During the winter of 1811 and 1812, and the spring of the latter year, frequent communications passed between the Commander of the forces and Major-General Brock, who commanded in Upper Canada, respecting the preparations which would be necessary in the event of a war. It was proposed to reinforce Amherstburgh, and Fort George; and supplies of provisions, cavalry-arms, accoutrements and money, were directed to be conveyed to Upper Canada. Accoutrements and clothing for the militia in the Canadas, were requested from the British Government. Another schooner was directed to be built, to increase our marine on Lake Erie. Captain Gray, Deputy Assistant-Quarter-Master-General, was despatched to the Upper Province, in order to assist in forwarding these defensive preparations; and Captain Dixon, of the Royal Engineers, was directed to proceed to Amherstburgh, to inspect the works of that fort, which the Commander of the forces had ordered to be put in a tenable state. The propriety of strengthening and fortifying York was submitted to Government; and the commanding engineer was directed to make the repairs, which his report on the different forts and posts in Upper Canada, had stated to be necessary. In addition to these measures, a reinforcement from the 41st regiment, and five companies of the Newfoundland Fencibles, left Quebec in the month of May for the Upper Province.
