He engaged more men, left Fort Frontenac on the 23d. day of July, 1680, and, although detained by head winds on Lake Ontario, reached Mackinac during the month of September. By offering brandy in exchange for Indian corn, he soon had enough to satisfy his needs, and, embarking on the rough waters of Lake Michigan, at length arrived at the mouth of the river Miami. The fort which he had left there had been plundered and dismantled! Journeying south, La Salle reached the villages of the Illinois, which he found had been sacked and burned by the Iroquois during his absence. He saw nothing of Tonty and those Frenchmen whom he had left behind him, a proof that they had either been killed or dispersed. So he returned to the Miami River and here spent the winter, visiting the Indian tribes near Lake Michigan. Here he learned that the Iroquois had attacked the settlements of the Illinois with vindictive ferocity, during his absence, driving the red men far westward across the Mississippi. As for the Frenchmen, whom he had left behind him, no one seemed to know what had become of them. Towards the end of May, 1681, the vigorous explorer left the Miami River, and, after a prosperous voyage, once more entered the harbor of Mackinac. What was his joy to here find the Chevalier Tonty and those Frenchmen, whom he had last seen in the wilderness. They had passed through great dangers, but had at length escaped from the bloodthirsty Iroquois and had reached the French fortress, lean, haggard, but praising God that they had escaped with their lives. La Salle embraced them all, gave them presents of firearms and blankets, and begged them to accompany him again into the wilderness. The Chevalier was now determined to journey down the entire length of the Mississippi, and, with this end in view, took into his service a company of Frenchmen, together with a number of eastern Indians, Abenakis, and Loups, or Mahingans, as they were called by the French writers. Putting Fort Frontenac in command of the Sieur de La Forest, he journeyed by canoe to Niagara, where a stockade had recently been built, called Fort de Tonty, and thence embarked with his entire company in canoes for the Miami River, which he reached in safety. Six weeks were now spent in making arrangements for the great trip down the river. There were twenty-three Frenchmen in the party, eighteen savages, ten Indian women, and three children. The redskins insisted on taking these women with them to prepare their food, according to their custom, while they were fishing and hunting. When all was ready the adventurers started for the mouth of the Chicago River, which was found to be frozen.
