It is still a matter of debate among philosophical historians, whether war, trade, or missionary effort has done the more toward opening the strange, wild places of the world. Each, doubtless, has done its part, but we shall find in the story of the Great Lakes, that the war canoes of the savages were followed by the Jesuit missionaries, and these in turn by the bateaux of the voyageurs employed by the Hudson Bay Company. After the Iroquois had learned the way, trips of war canoes up and down the lakes, were annual occurrences, and warfare was almost perpetual. In 1680 the Iroquois, 700 strong, invaded Illinois, killed 1200 of the tribe there established, and drove the rest beyond the Mississippi. For years after the Iroquois nation were the rulers of the water-front between Lake Erie and Lake Huron. While this tribe was in undisputed possession, commerce had little to do with the navigation of the Great Lakes. The Indians went up and down the shores on long hunting trips, but war was the principal business, and every canoe was equipped for a fray at any time. A story is told of a great naval battle that was fought on Lake Erie, nearly two centuries before the first steamer made its appearance on that placid water. A Wyandot prince, so the tale goes, fell in love with a beautiful princess of the Seneca tribe, who was the promised bride of a chief of her own nation. The warrior failed to win the heart of the dusky maiden, and goaded to desperation, entered the Senecas country by night, and carried off the lady. War immediately followed, and was prosecuted with great cruelty and slaughter for a long time. At last a final battle was fought, in which the Wyandots were worsted and forced to flee in great haste. The fugitives planned to cross the ice of the Straits (Detroit) River, but found it broken up and floating down stream. Their only alternative was to throw themselves on the floating ice and leap from cake to cake; they thus made their escape to the Canadian shore, and joined the tribes of the Pottawatomies, Ottawas, and Chippewas. A year later the Wyandots, equipped with light birch canoes, set out to defeat the Senecas, and succeeded in inducing them to give combat on the water. The Senecas made a fatal mistake and came out to meet the enemy in their clumsily-constructed boats hollowed out of the trunks of trees. After much maneuvering the birch canoe fleet proceeded down Lake Erie to the head of Long Point, with the Senecas in hot pursuit. In the center of the lake the Wyandots turned and gave the Senecas so hot a reception that they were forced to flee, but could not make good their escape in their clumsy craft, and were all slain but one man, who was allowed to return and report the catastrophe to his own nation. This closed the war.
