 On 11 November, Morrison's force, aided by three gunboats under Mulcaster, defeated the Americans at the Battle of Crysler's Farm.The last event of the year was the transport of William Henry Harrison's troops from the Niagara to Sackett's Harbor, to replace Wilkinson's army.However, this left the Niagara frontier denuded of regular troops, and the British took advantage of this in the Capture of Fort Niagara and the Battle of Buffalo.
