This chain of allies, with Du Luth's fort at Detroit and a partial control over Niagara, had given New France nearly all the fur trade of the Great Lakes. The English Governor Dongan, of New York, dared not to fight openly for it, but he armed the Iroquois and set them against the French. Menard had laughed when the word came, in 1684, from Father de Lamberville, whose influence worked so far toward keeping the Iroquois quiet, that Dongan had pompously set up the arms of his king in each Iroquois village, even dating them back a year to make his claim the more secure. Every old soldier knew that more than decrees and coats of arms were needed to win the Five Nations. When La Barre succeeded Frontenac, lacking the tact and firmness which had established Frontenac's name among foes and allies alike, he fell back upon bluster (to say nothing of the common talk in Quebec that he had set out to build up his private fortune by the fur trade). Learning that, by his grant of Fort Frontenac, La Salle was entitled to a third of the trade that passed through it, he seized the fort. He weakened La Salle's communications so greatly that La Salle and Tonty could not make good their promises of French protection to the Illinois. This made it possible for the Iroquois, unhindered, to lay waste the Illinois country. By equally shortsighted methods, La Barre so weakened the ties that bound the northern allies, and so increased the arrogance of the Iroquois, that when Governor Denonville took up the task, most of the allies, always looking to the stronger party, were on the point of going over to the Iroquois. This would give the fur trade to the English, and ruin New France. Governor Dongan seized the moment to promise better bargains for the peltry than the French could offer. It remained for the new governor to make a demonstration which would establish firmly the drooping prestige of New France.
