In 1685 he appeared once more at Green Bay, this time holding the position of Commandant of the West, with a little company of twenty soldiers. He now had almost unlimited authority to explore and traffic as he would, for the only salary an official of that sort used to get, in New France, was the right to trade with the Indians. He had already lost money in working for the government as an Indian agent, and his present operations were wholly directed toward getting it back again. He went up the Fox and down the Wisconsin, and then ascended the Mississippi to trade with the wild Sioux tribe. For headquarters, he erected a little log stockade on the east bank of the Mississippi, about a mile above the present village of Trempealeau, and south of the mouth of Black River. In the year 1888, the site of this old stockade was discovered by a party of historical students, and many of the curious relics found there can now be seen in the museum of the State Historical Society, at Madison.
All through the winter of 1685-86, Perrot traded here with the Sioux. He had a most captivating manner of treating Indians; for a long time, few of them ventured to deny any request made by him. Chiefs from far and near would come to the Trempealeau "fort," as it was called, and hold long councils and feasts with the great white chief, and more than once he was subjected to the curious Sioux ceremony of being wept over. A chief would stand over his guest and weep copiously, his tears falling upon the guest's head; when the chief's tear ducts were exhausted, he would be relieved by some headman of the tribe, who in turn was succeeded by another, and so on until the guest was well drenched. This must have been a very trying experience to Perrot, but he was shrewd enough to pretend to be much pleased by it.
In the spring of 1686, the same year in which he gave the silver ostensorium to the Jesuit chapel at De Pere, the commandant proceeded up the Mississippi to the broadening which was, about this time, named Lake Pepin by the French. On the Wisconsin shore, not far above the present village of Pepin, he erected another and stronger stockade, Fort St. Antoine. It was here, three years later, that, after the manner of Saint Lusson at Sault Ste. Marie, he formally took possession, in the name of his king, of all the Upper Mississippi valley.
Several other forts were built by Perrot along the Mississippi, none of them more than groups of stout log houses. These were surrounded by a stockade wall of heavy logs well planted in the ground, sharpened at the top, pierced for musket fire, and sometimes surmounted by a small cannon. The stockade whose ruins were unearthed at Trempealeau, measured about forty-five by sixty feet. One of his stockades, Fort Perrot, was on the Minnesota shore of Lake Pepin; still another, Fort St. Nicholas, was near the "lower town" of the Prairie du Chien of to-day, at the confluence of the Wisconsin and the Mississippi; and it also appears that he had a stockade lower down the Mississippi, to guard a lead mine which he had discovered near Galena, because lead was an important article for both fur traders and Indians. Sometimes traders fought among themselves, for the possession of a lead mine.
Perrot made frequent voyages to the settlements on the St. Lawrence River, and engaged in some of the French expeditions against the hostile Iroquois of New York. While, on the whole, he was successful in holding the Western tribes in friendship to New France, his position was not without grave perils. One time his old friends, the Mascoutins, rose against him, claiming that he had killed one of their warriors. The claim may have been true, for he was a man of violent temper, and ruled the Wisconsin forests after the despotic fashion of an Asiatic prince. The Mascoutins captured Perrot, in company with a Pottawattomie chief, and carrying them to their village, robbed the commandant of all his furs, and decided to burn the prisoners at the stake. But while being conducted to the fire, the two managed by artifice to escape, and at last reached in safety their friends at the mouth of the Fox River. Another time, the Miamis captured Perrot, and would have burned him except for the interference of the Fox Indians, with whom he was friendly.
In 1699, owing to the uprising of the Foxes, the king ordered that all the Western posts be abandoned, and their little garrisons removed to Montreal and Quebec. Thus suddenly ended the career of Perrot, who returned a poor man, for his recent losses in furs had been heavy, and his expenses of keeping up the posts large. Again and again he sought redress from the government, and the Wisconsin Foxes earnestly pleaded that he be sent back to them, as "the best beloved of all the French who have ever been among us." But his star had set, he no longer had influence; and it had just been decided to punish his friends the Foxes. Perrot lived about twenty years longer, on the banks of the Lower St. Lawrence, and died in old age, like Joliet, in neglect and poverty.
During much of the time that Perrot was commandant of the West, several other great fur traders were conducting operations in Wisconsin. The greatest of these was the Chevalier La Salle, the famous explorer, who plays a large part on the stage of Western history, particularly in the history of the Mississippi valley. It has been claimed for La Salle that he was in Wisconsin in 1671, two years before Joliet, and actually canoed on the Mississippi River, but this is more than doubtful. We do know that in 1673 one of his agents was trading with the Sioux to the west of Lake Superior; and that in 1679 he came to Green Bay in a small vessel called the Griffin, the first sailing craft on the Great Lakes above the cataract of Niagara. La Salle was a coureur de bois, most of this time, for he operated in a field far larger than that for which he had a license. Leaving his ship, which was afterward wrecked, he and fourteen of his men proceeded in canoes southward along the western coast of Lake Michigan, visiting the sites of Milwaukee and other Wisconsin lakeshore cities. Finally, after many strange adventures, they ascended St. Joseph River, crossed over to the Kankakee River, and spent the winter in a log fort which they built on Peoria Lake, a broadening of the Illinois River.
At least one priest was thought necessary in every well-equipped exploring expedition. La Salle had quarreled with the Jesuits, and hated them; hence the ministers of religion in his party were three Franciscan friars, one of them being Father Louis Hennepin, who afterward became famous. When La Salle determined to spend the winter at Peoria Lake, he sent Hennepin forward with two coureurs de bois, to explore the upper waters of the Mississippi. These three adventurers descended the Illinois River in their canoe, and then ascended the Mississippi to the Falls of St. Anthony, where now lies the great city of Minneapolis; there they met some Sioux, and went with them upon a buffalo hunt. But the Indians, although at first friendly, soon turned out to be a bad lot, for they robbed their guests, and practically held them as prisoners.
This was in the early summer of 1680. Luckily for Hennepin and his companions, the powerful coureur de bois, Daniel Graysolon Duluth (du Luth) appeared on the scene. Duluth was, next to Perrot, the leading man in the country around Lake Superior and the Upper Mississippi valley. He had been spending the winter trading with the Sioux in the lake country of northern Minnesota, and along Pigeon River, which is now the dividing line between Minnesota and Canada. With a party of ten of his boatmen, he set out in June to reach the Mississippi, his route taking him up the turbulent little Bois Brulé River, over the mile and a half of portage trail to Upper Lake St. Croix, and down St. Croix River to the Mississippi. On reaching the latter, he learned of the fact that Europeans were being detained and maltreated by the Sioux, and at once went and rescued them. The summer was spent among the Indians in company with Hennepin's party, who, now that Duluth was found to be their friend, were handsomely treated. In the autumn, Duluth, Hennepin, and their companions all returned down the Mississippi, up the Wisconsin, and down the Fox, and spent the winter at Mackinac. After that, Duluth was frequently upon the Fox-Wisconsin route, and traded for buffalo hides and other furs with the Wisconsin tribes.
