Dollard des Ormeaux, Adam (ädäNˈ dôlärˈ dāzôrmōˈ) [key], 1635–1660, garrison commander of the fort at Ville-Marie (Montreal), b. France. He probably went to Canada in 1658. In the spring of 1660 he led a small party of Frenchmen up the Ottawa River to wage war on the Iroquois. At Long Sault Rapids he and his companions were killed after a week's defense in an improvised fort against a large band of Iroquois. Their resistance, however, probably delayed an Iroquois plan to attack New France.
