On 25 May, 1813, the American fleet and the batteries at Fort Niagara across the river began a devasttating two day bombardment of Fort George. On the 27th a large American force was landed and after a brief engagement in which his out numbered garrison sustained heavy casualties, Brigadier General John Vincent made an orderly withdrawl toward Burlington. The capture of Fort George left the Americans in control of the Niagara frontier, but Vincent's troops a week later won a decisive victory at Stoney Creek, preventing the Americans from gaining the whole peninsula.
