Fort Drummond
This small redoubt, or square fortification, and the U-shaped advance battery, named in honour of Sir Gordon Drummond, were built in the late spring of 1814 to defend the main portage road from Chippawa to Queenston. The earthworks enclosed a blockhouse which sheltered 100 men. After the British defeat at the battle of Chippawa, these men abandoned Fort Drummond and joined Major-General Riall's forces retiring to Fort George on 10 July 1814. For two weeks the fort and surrounding heights were held by American forces. When they retreated to Lundy's Lane, the British reoccupied Fort Drummond.
