Of the five great portage routes used by the French,[3] the Maumee-Wabash was the last to be exploited, for, unlike the more northern routes, it was along the line of “most resistance”. The Iroquois warfare in this region and as far west as the Illinois country made it virtually impossible for the French to use the routes extending through southern Lake Erie. With the establishment of the French posts along the lower Mississippi, however, the Maumee-Wabash portage gained importance, as it proved to be the shortest route connecting the settlements of New France (Canada) and Louisiana. The first white man to use this portage may have been some unknown French “coureur de bois”, pursuing his lawless life of adventure and fur-trading. There is some claim that LaSalle used the Maumee-Wabash portage in his explorations of 1670 or later, but it is based, for the most part, on conjecture and is still open to various interpretations.[4] In any event, LaSalle’s description of the territory between Lake Erie and Lake Michigan indicates a familiarity with the region, and it was he who first directed the attention of the French to this portage by pointing out the way to shorten the route to the lower Ohio river.[5] Whatever LaSalle’s plans were for opening up this easy channel of communications[6] they had to be abandoned because of the failure of the French to appease the Iroquois. This powerful confederacy had all but annihilated the Erie Indians earlier in the century and were now pressing their attacks upon the western tribes south of Lake Michigan. Out of fear of the Iroquois the area of Indiana was largely abandoned by the Miamis and other related tribes. Therefore by the 1670’s, when LaSalle set out to achieve his great objective, control of the Mississippi for the French, he found it necessary “to go to the Illinois [river] through the lakes Huron and Illinois [Lake Michigan] as the other routes which I have discovered by the head of Lake Erie and by the southern shore of the same, have become too hazardous by frequent encounters with the Iroquois who are always on that shore.”[7] That this route had become “too dangerous” is indicated by the letter of Jean de Lamberville to Count de Frontenac on Sept. 20, 1682, in which he expressed his fears that “an Iroquois army, twelve hundred strong ... would completely annihilate the Miamis and their neighbors the Siskakon [Kiskakon] and Ottawa tribes on the headwaters of the Maumee.”[8]
