The Foxes began to make it disagreeable for the French in Wisconsin. They insisted on collecting tolls on fur trade bateaux which were being propelled up the Fox River, and even stopped traders entirely; several murders of Frenchmen were also charged to them. The French thereupon determined to punish these rebellious savages who sat within the chief gateway to the Mississippi. In the winter of 1706-07, a large party of soldiers, coureurs des bois, and half-breeds, under a captain named Marin, ascended the Fox River on snowshoes and attacked the Foxes, together with their allies, the Sacs, at a large village at Winnebago Rapids, near where is now the city of Neenah.
Several hundreds of the savages were killed in this assault, but its effect was to make the Foxes the more troublesome. A few summers later, this same Marin arranged again to surprise the enemy. His boats were covered with oilcloth blankets, in the manner adopted by the traders to protect the goods against rain; only two voyageurs were visible in each boat to propel it. Arriving at the foot of Winnebago Rapids, the canoes were ranged along the shore, and nearly fifteen hundred Indians came out and squatted on the bank, ready to collect toll of the traders. All of a sudden the covers were thrown off, and the armed men appeared and raked the Indians with quick volleys of lead, while a small cannon in Marin's boat increased the effectiveness of the attack. Tradition says that over a thousand Foxes and Sacs fell in this massacre; this is one of the many incidents in white men's relations with the Indians, wherein savages were outsavaged in the practice of ferocious treachery.
Despite the great slaughter, there appear to have been enough Foxes left to continue giving the French a great deal of annoyance. There were fears at Quebec that it might be necessary to abandon the attempt to connect New France and Louisiana by a trail through the Western woods, in which case the English would have a free run of the Mississippi valley. There seem, however, not to have been any more warlike expeditions to Wisconsin for several years. But in May, 1712, the French induced large numbers of the Foxes, with their friends, the Mascoutins, the Kickapoos, and the Sacs, to come to Detroit for the making of a treaty of peace. At the same time the French also assembled there large bands of the Pottawattomies and Menominees from Wisconsin, with Illinois Indians, some camps from Missouri, and Hurons and Ottawas from the Lake Huron country; all of these were enemies of the Foxes.
The records do not show just why it happened; but for some reason the French and their allies fired on the Foxes and their friends, who were well intrenched in a palisaded camp outside the walls of Detroit. A great siege ensued, lasting nineteen days, in which the slaughter on both sides was heavy; but at last the Foxes, worn out by loss of numbers, hunger, and disease, took advantage of a dark, rainy night to escape northward. They were pursued the following day, but again intrenched themselves with much skill, and withstood another siege of five days, when they surrendered. The French and their savage allies fell upon the poor captives with fury and slew nearly all of them, men, women, and children.
The poor Foxes had lost in this terrible experience upward of fifteen hundred of the bravest of their tribe, which was now reduced to a few half-starved bands. But their spirit was not gone. Next year the officers at Quebec wrote home to Paris: "The Fox Indians are daily becoming more insolent." They had begun to change their tactics; instead of wasting their energies on the French, they began to make friends with, or to intimidate, neighboring tribes. By means of small, secret war parties, they would noiselessly swarm out of the Wisconsin forests and strike hard blows at the prairie Indians of Illinois, who preferred to remain their enemies. In this manner the Illinois Indians were reduced to a mere handful, and were compelled to seek shelter under the guns of the French fort at Kaskaskia. At the same time the Foxes were in close alliance with the Sioux and other great western tribes, who helped them lock the gate of the Fox-Wisconsin rivers, and plunder and murder French traders wherever they could be found throughout Wisconsin.
Again it seemed evident that New France, unless something were done, could never maintain its chain of communication with Louisiana, or conduct any fur trade in the Northwest. The something decided on was an attempt to destroy the Foxes, root and branch. For this purpose there was sent out to Wisconsin, in 1716, a well-equipped expedition under an experienced captain named De Louvigny, numbering eight hundred men, whites and Indians. The Foxes were found living in a walled town upon the mound now known as Little Butte des Morts, on the west side of Fox River, opposite the present Neenah. The wall consisted of three rows of stout palisades, reënforced by a deep ditch; tradition says there were here assembled five hundred braves and three thousand squaws and other noncombatants.
The French found it necessary to lay siege to this forest fortress, just as they would attack a European city of that time; trenches and mines were laid, and pushed forward at night, until, at the close of the third day, everything was ready to blow up the palisades. At this point the Foxes surrendered, but they gained easy terms for those days, for De Louvigny was no butcher of men, and appeared to appreciate their bravery. They gave up their prisoners, they furnished enough slaves to the allies of the French to take the place of the warriors slain, they agreed to furnish furs enough to pay the expenses of the expedition, and sent six hostages to Quebec to answer for their future behavior. The next year, De Louvigny returned to the valley of the Fox, from Quebec, and made a treaty with the Foxes, but nothing came of it. Treaties were easily made with Indian tribes, in the days of New France, and as easily broken by either side.
In the very next year, the Foxes were again making raids on the French-loving Illinois, and the entire West was, as usual, torn by strife. It was evident that the Foxes were trying to gain control of the Illinois River, and thus command both of the principal roads to the Mississippi. The French were at this time enthusiastic over great schemes for opening mines on the Mississippi, operating northward from Louisiana; agriculture was beginning to flourish around Kaskaskia; and grain, flour, and furs were being shipped down the Mississippi to the French islands in the West Indies, and across the ocean to France. More than ever was it necessary to unite Louisiana with Canada by a line of communication.
But just now the Foxes were stronger than they had been at any time. Their shrewd warriors had organized a great confederacy to shut out the French, and thereby advance the cause of English trade, although it is not known that the English assisted in this widespread conspiracy. Fox warriors were sent with pipes of peace among the most distant tribes of the West, the South, and the North, and it seemed as if the whole interior of the continent were rising in arms. A French writer of the period says of the Foxes: "Their fury increased as their forces diminished. On every side they raised up new enemies against us. The whole course and neighborhood of the Mississippi is infested with Indians with whom we have no quarrel, and who yet give to the French no quarter."
This condition lasted for a few years. But Indian leagues do not ordinarily long endure. We soon find the Foxes weak again, with few to back them; in 1726, at a council in Green Bay, they were apologizing for having made so much trouble. The French were, however, still afraid of these wily folk, and two years later (1728) a little army of four hundred Frenchmen and nine hundred Indian allies advanced on the Fox villages by way of the Ottawa River route and Mackinac. The Foxes, together with their Winnebago friends, had heard of the approach of the whites, and fled; but the white invaders burned every deserted village in the valley, and destroyed all the crops, leaving the red men to face the rigor of winter with neither huts nor food.
