Perry’s victory and Harrison’s defeat of the British virtually decided the war along the Lakes, although, during the following winter, the British prepared to make one more tremendous effort to regain a part of the supremacy they had lost. This effort was to be made on Lake Ontario. During the whole of the winter of 1813-14, both Yeo and Chauncey strained every resource to prepare themselves for this final conflict, and it was during this time that the largest ships of war that ever floated on the Lakes were built, among them being the American ship _Superior_, to carry sixty-two guns, and the British ships _Prince Regent_, fifty-eight, and the _Princess Charlotte_, forty-two. The two fleets were pretty evenly matched, each squadron having eight ships, but with the Americans leading in tonnage, number of men, and guns. Yeo, however, was prepared for battle earlier than Chauncey, and taking advantage of this he prepared to attack Oswego, which was garrisoned by less than three hundred men and was in a wretched state of defence. On the 3d of May he set sail, having on board his squadron a detachment of over a thousand troops. The fire of the fort was drawn on the fifth, but it was not until the following day that the battle began in earnest, when five of the British warships began a terrific bombardment under cover of which eight hundred troops and two hundred seamen were landed. The little garrison fought with desperate valour and when they were finally driven from their position the British had lost ninety-five men, a number a third as great as the American force opposed to them. The Americans lost six men killed and thirty-eight wounded, the remainder escaping to the Falls.
