A few words are needed in further explanation of the "camp volant" above alluded to.
"In 1642," according to Benjamin Suite, Canadian Antiquarian and Numismatic Journal, 1879, "there were no less than seventy soldiers at Three Rivers whose duty it was, not only to defend that place against the Iroquois, but to patrol Lake St. Peter also. The same year only fifteen soldiers were quartered at Quebec--a much less exposed position than Three Rivers. In the year 1644 some troops were sent to Canada by Anne d'Autriche. Twenty-three of these soldiers accompanied the Hurons, the missionaries and a few Frenchmen, who went to the Georgian Bay that summer. M. Ferland says that the garrison of Montreal numbered thirty men in 1647; but he evidently means the thirty men placed under the orders of Jean Bourdon for reconnaissance purposes on Lake St. Peter." These were "soldiers" from 1642; from 1649 there were volunteers, and from 1651, if not before, a sedentary militia was established.
About 1647 Montmagny had considered a project for forming an active militia to be on the lookout against the Iroquois, but his resources were too slender. In the spring of 1649 the "camp volant" was organized under the command of Charles J. d'Ailleboust de Musseaux, nephew of the new governor general, M. d'Ailleboust. It numbered forty men and its duty consisted in patrolling on the St. Lawrence between Montreal and Three Rivers.
After the slaughter of Sieur Duplessis Kerbodot, nephew of M. Lauson, now governing and the successor of de Musseaux, on August 19th, together with fifteen Frenchmen, the "camp volant" became disorganized for the winter, but it was apparently reformed in the summer of 1653. After that it seems to have been neglected during the government of D'Argenson and D'Avaugour. In fact a body of regular troops was required to check the Iroquois, and not mere militia, whose men could not attend to their farm and other business and at the same time keep beating the country nearly all the year round. Hence the request for troops, of Father Lejeune in 1660, and Pierre Boucher in 1661. In 1663 a body of militia was organized at Montreal.
The next spring, 1640, the "camp volant" of forty men was sent to Montreal under the command of the nephew of the new governor, Charles d'Ailleboust des Musseaux, to help to repulse the Iroquois. About the same time the new governor went to pay his first official visit to Ville Marie.
