In the closing phase of the struggle by land and sea the fortunes of war may, with the single exception of Plattsburg, be most conveniently followed territorially, from one point to the next, along the enormous irregular curve of five thousand miles which was the scene of operations. This curve begins at Prairie du Chien, where the Wisconsin joins the Mississippi, and ends at New Orleans, where the Mississippi is about to join the sea. It runs easterly along the Wisconsin, across to the Fox, into Lake Michigan, across to Mackinaw, eastwards through Lakes Huron, Erie, and Ontario, down the St Lawrence, round to Halifax, round from there to Maine, and thence along the whole Atlantic coast, south and west--about into the Gulf of Mexico. The blockade of the Gulf of Mexico was an integral part of the British plan. But the battle of New Orleans, which was a complete disaster for the British arms, stands quite outside the actual war, since it was fought on January 8, 1815, more than two weeks after the terms of peace had been settled by the Treaty of Ghent. This peculiarity about its date, taken in conjunction with its extreme remoteness from the Canadian frontier, puts it beyond the purview of the present chronicle. All the decisive actions of the campaign proper were fought within two months. They began at Prairie du Chien in July and ended at Plattsburg in September. Plattsburg is the one exception to the order of place. The tide of war and British fortune flowed east and south to reach its height at Washington in August. It turned at Plattsburg in September. Neither friend nor foe went west in 1813. But in April 1814 Colonel McDouall set out with ninety men, mostly of the Newfoundland regiment, to reinforce Mackinaw. He started from the little depot which had been established on the Nottawasaga, a river flowing into the Georgian Bay and accessible by the overland trail from York. After surmounting the many difficulties of the inland route which he had to take in order to avoid the Americans in the Lake Erie region, and after much hard work against the Lake Huron ice, he at last reached Mackinaw on the 18th of May. Some good fighting Indians joined him there; and towards the end of June he felt strong enough to send Colonel McKay against the American post at Prairie du Chien. McKay arrived at this post in the middle of July and captured the whole position--fort, guns, garrison, and a vessel on the Mississippi.
