Adam Dollard des Ormeaux, (1635 – May, 1660), usually known simply as Dollard des Ormeaux, was a colonist of New France who, as garrison commander, led his companions from the fort of the newly founded town of Ville Marie (also known as Montreal) in 1660 to ambush a larger force of Iroquois.
At the time, Ville Marie (which would later become Montreal), had a population of about 600. Through the Indian allies of the colonists, rumours were heard that the Iroquois would soon come in force from the west to exterminate the new settlement.
Nothing is known of Dollard’s activities prior to his arrival in Canada. Having come to Montreal as a volunteer, very probably in 1658, he continued his military career there. In 1659 and 1660, he was described as an officer or garrison commander of the fort of Ville-Marie, a title that he shared with Pierre Picoté de Belestre. It is not known what his particular responsibility was. Dollard was perhaps contemplating becoming a settler. At the end of 1659, Chomedy de Maisonneuve gave him a piece of land comprising 30 arpents (10 hectares). In 1661, the sum that Dollard had devoted "to having work done on the aforementioned grant" was calculated at 79 livres, 10 sols, "for 53 days’ labour." Although first-hand evidence is rare, Dollard had an excellent reputation in Montreal.
