In these days, the Lakes were already playing a part in commerce as well as in war. Great fleets of Indian canoes made annual voyages from the Upper to the Lower Lakes, and war fleets were common spectacles from almost every coast. The greatest of these fleets, so far as is known, was that of the Iroquois, which in 1680 carried six hundred selected braves across Lake Erie, up the Detroit River, through Lake St. Clair, Lake Huron, the Straits of Mackinaw, and down to the foot of Lake Michigan, where the adventurous navigators were utterly repulsed by the warriors of the Illinois. Another Iroquois fleet was annihilated near Iroquois Point, in Lake Huron. In 1600, according to stories told by the Indians, a fierce naval battle in which several hundred war canoes were engaged was fought in the middle of Lake Erie by the Wyandots and the Senecas. Only one Seneca canoe escaped. It was at this time, when the Lake country and the Lakes themselves were the stage upon which were being played the most thrilling dramas of aboriginal history, that the Inland Seas were first visited by their white discoverers. In 1615, the Franciscan friar, Joseph Le Caron, in company with three other Franciscans and twelve Frenchmen, invaded the seat of the Huron nation on Matchedash Bay, where Champlain joined him a few days later. The Hurons were preparing to attack their old enemies, the Iroquois, and Champlain accompanied them on their expedition. The campaign was unsuccessful but it led to the Frenchman’s discovery of Lake Ontario. Stephen Brule, an unlettered and reckless adventurer, was the first white man to rest eyes upon Lake Superior, his voyage up Lake Huron being made some time in 1629. Brule, however, was more interested in ingots of copper which he found than in the greatest body of fresh water on the globe, and he returned south almost immediately, while it was left for Raymbault and Jogues, two hopeful missionaries in search of a passage to China, to make the first navigation of Superior. This they did in 1641. Five years after Brule’s discovery, another adventurer, Jean Nicolet, paddled in a birch canoe from Georgian Bay across Lake Huron and through the Straits of Mackinaw, and thus discovered Lake Michigan. As surprising as it may seem, Erie was the last of the Great Lakes to be found by white men, and although its existence was known to the French as early as 1640, it was not until 1669 that Joliet, its discoverer, made his voyage upon it.
