During the winter of 1812-13 strenuous efforts were made by the American Government in forwarding stores and reinforcements to their Ontario frontier. They massed these men in three divisions for the coming invasion of Canada. General Dearborn was placed in command of the Army of the Centre, and at the opening of the spring of 1813 had collected his forces, 3,000 at Buffalo, 3,300 on the Niagara frontier, and 4,000 at Sackett's Harbour. To the east 5,000 men had been concentrated at Lake Champlain, and to the west 2,000 men were in fortified camp under General Harrison, on the banks of the Miami, immediately to the south of Detroit.

Commodore Chauncey was in control of the naval operations with his headquarters at Sacketts' Har-
bour at the east end of Lake Ontario. [Source]
