The Battle of the Lake of Two Mountains (French: Bataille du Lac-des-Deux-Montagnes) took place during the Beaver Wars between the colony of New France and the Haudenosaunee Confederacy that occurred on October 16, 1689.
The battle occurred in response to the Lachine massacre of August 1689. In October, Governor General of New France, the Marquis de Denonville dispatched a scouting party of 28 coureur des bois, under the command of Daniel Greysolon, Sieur du Lhut and Nicolas d'Ailleboust de Manthet, to search for Haudenosaunee warriors that posed a threat to residents on the Island of Montreal. The coureur des bois came across a group of 22 Haudenosaunee at the Lake of Two Mountains. The French suffered no casualties, while the Haudenosaunee suffered 18 deaths, 3 captured, and 1 fled. The French victory restored the confidence of the local French inhabitants.
