It was not until some time in May, 1681, that Du Lhut arrived at Montreal, and although he protested that his journey had only been in the interest of discovery and of peace-making with the tribes, the Intendant of Justice accused him of violating the King’s edict against trading with the Indians, and Frontenac held him for a time in the castle at Quebec, more as a friend than as a prisoner. It was but a little while before an amnesty came from the King of France to all suspected of being “_coureurs des Bois_,” and authorizing Governor Frontenac to issue yearly twenty-five licenses to twenty-five canoes, each having three men, to trade among the savages. Duchesneau, the Intendant of Justice, still complained that the Governor winked at illicit trade, and on the 13th of November, 1681, he wrote to Seignelay, who had succeeded his father as Minister for the Colonies:— “But not content with the profits to be derived within the countries under the King’s dominion, the desire of making money everywhere has led the Governor, Sieurs Perrot, Boisseau, Du Lhut, and Patron, his uncle, to send canoes loaded with peltries to the English. It is said that sixty thousand livres’ worth has been sent thither; and though proof of this assertion cannot be adduced, it is a notorious report.... Trade with the English is justified every day, and all those who have pursued it agree that beaver carried to them sells for double what it does here, for that worth fifty-two sous, six deniers, the pound, duty paid, brings eight livres there, and the beaver for Russia sells there at ten livres the pound in goods.” On grounds of public policy Frontenac in 1682 was recalled, and De la Barre, his successor, in October of this year held a conference with the most influential persons, among whom was Du Lhut, who afterward sailed for France, and early in 1683[504] there wrote the letter to Seignelay from which extracts have been made. The Iroquois having found it profitable to carry the beavers of the northwest to the English at Albany, determined to wage war against the tribes of the upper Lakes, seize Mackinaw, and drive away the French. Governor de la Barre, to thwart this scheme, in May, 1683, sent Oliver Morrel, the Sieur de la Durantaye, with six canoes and thirty good men, to Mackinaw, and the Chevalier de Baugy was ordered to the fort established by La Salle on the Illinois River, in charge of Tonty. As soon as Durantaye reached Mackinaw, he immediately sent parties to Green Bay to take steps to humble the Pottawattamies for the hostility exhibited toward the French. He afterward went down the west side of Lake Michigan, and Chevalier de Baugy proceeded on the other side, hoping to meet La Salle, who was expected to go to Mackinaw by following the eastern shore.
