The American plan of campaign was to invade Canada with three armies. One was to cross at Detroit, a second at the Niagara frontier, and the third by the way of Lake Champlain. These were the armies of the West, the Centre, and the North respectively, General Dearborn being the Commander-in-Chief.
The first blow was struck at Fort Michillimackinac at the entrance of Lake Michigan. This post was held by the Americans, and was important on account of its trade with the western Indians. Acting under orders from General Brock, Captain Roberts with a small body of men from St. Joseph, took the fort by surprise, and by so doing secured the support and confidence of the Indian tribes of the West and North-west. On the 12th of July, the American general, Hull, crossed over from Detroit, and by a proclamation invited the Canadians to throw off the yoke of England; but the invitation met with no response. General Brock immediately sent Colonel Proctor with a few regulars to Fort Malden, near Amherstburg. Here Proctor was joined by the famous Indian chief, Tecumseh, who brought a number of warriors to help the English in the struggle against the Americans. Tecumseh was a Shawnee, and for years had sought to unite the various Indian tribes against the Americans, for he saw very clearly that the Indians were being pushed back, farther and farther, by the steady encroachments of the white people. At this time, Tecumseh was in the prime of his noble manhood, and wielded a great influence over the Indian tribes, who believed him to be of supernatural birth.
For a short time, Hull remained in Canada, and then getting afraid of Indian attacks, returned to Detroit and shut himself up in that strong fort. On the 5th of August, Brock set out for Detroit with a small force of regulars and York militia. A week later he reached Amherstburg, and there met Tecumseh with seven hundred warriors. Tecumseh sketched for Brock, on a piece of birch bark, the plan of Detroit, and it was resolved to attempt its capture, although Brock had only fourteen hundred men, half of them Indians, while Detroit was defended by over two thousand. Brock demanded the surrender of the fort, and the demand being refused, crossed the river and made preparations for an attack. Greatly to the surprise of the English and the Indians, and to the garrison itself,
