Adam Dollard des Ormeaux, (July 23, 1635 – May 21, 1660), also known as Adam Daulaut, Daulac, or simply as Dollard des Ormeaux, was a colonist and soldier of New France. As garrison commander, in 1660 he led his companions and native (mostly Huron) allies from the fort at the town of Ville-Marie (later to be known as Montreal), with its population of 600 colonists, to an area up the Ottawa River known as Long Sault (near present-day Carillon, Quebec). The exact nature or purpose of Dollard's 1660 expedition is uncertain, but it is believed that they intended to ambush a larger force of Iroquois warriors that were rumoured to be approaching from the west to attack the French colonists.
