Fort George was taken in May, 1813, by a large American force, under General Dearborn, which compelled Major-General Vincent to withdraw his troops from Fort Erie and Chippewa, and to retreat to Burlington Heights, at the head of Lake Ontario, the British losing 52 killed, besides upwards of 300 wounded and missing. Immediately after the capture of Fort George, General Dearborn pushed forward a body of 3,000 infantry, with nine field pieces and 250 cavalry, for the purpose of dislodging Major-General Vincent from his position. Lieut.-Colonel Harvey,[126] deputy adjutant-general, proposed a night attack on this body, which was approved, and with the 49th, under Major Plenderleath, and five companies of the 8th, under Major Ogilvie, (the whole only 704 firelocks,) he led the attack in gallant style, and completely succeeded in surprising the enemy, who evinced a highly creditable state of order and discipline in repeatedly forming, though compelled as often to disperse before the resistless energy of the British bayonet. Two brigadiers, (Chandler and Winder,) 7 other officers and 116 men, with three guns and one brass howitzer, were taken in this intrepid attack, which, as it reduced the Americans from offensive to defensive operations, was of the greatest importance to the salvation of the Upper Province. The enemy, however, occupied Fort George till the month of December, when they were compelled to evacuate it and retreat across the Niagara.[127] In that month, Colonel Murray surprised, and very gallantly captured by a night assault, Fort Niagara, which was retained by the British till the end of the war.

On the other hand, the necessity of retaining a post so favorably situated, if in the hands of an enemy, for annoying the British north-western trade, pressed itself on Sir George Prevost;
