Louvigny had brought with him two cannon and a mortar; but being light, they had little effect on the wooden wall, and as he was provided with mining tools, he resolved to attack the Outagamie stronghold by regular approaches, as if he were besieging a fortress of Vauban. Covered by the fire of three pieces of artillery and eight hundred French and Indian small-arms, he opened trenches during the night within seventy yards of the palisades, pushed a sap sixty feet nearer before morning, and on the third night burrowed to within about twenty-three yards of the wall. His plan was to undermine and blow up the palisades.
The Outagamies had made a furious resistance, in which their women took part with desperation; but dreading the threatened explosion, and unable to resist the underground approaches of their enemy, they asked for a parley, and owned themselves beaten. Louvigny demanded that they should make peace with all tribes friendly to the French, give up all prisoners, and make war on distant tribes, such as the Pawnees, in order to take captives who should supply the place of those they had killed among the allies of the French; that they should pay, in furs, the costs of the war, and give six chiefs, or sons of chiefs, as hostages for the fulfilment of these conditions.[336]
On the twelfth of October Louvigny reached Quebec in triumph, bringing with him the six hostages.
The Outagamie question was settled for a time. The tribe remained quiet for some years, and in 1718 sent a deputation to Montreal and renewed their submission, which the governor accepted, though they had evaded the complete fulfilment of the conditions imposed on them. Yet peace was not secure for a moment. The Kickapoos and Mascoutins would not leave their neighbors, the Illinois, at rest; the Saginaws made raids on the Miamis; and a general war seemed imminent. "The difficulty is inconceivable of keeping these western tribes quiet," writes the governor, almost in despair.[337]
At length the crisis came. The Illinois captured the nephew of Oushala, the principal Outagamie war-chief, and burned him alive; on which the Outagamies attacked them, drove them for refuge to the top of the rock on which La Salle's fort of St. Louis had been built, and held them there at mercy. They would have starved to death, had not the victors, dreading the anger of the French, suffered them to escape.[338] For this they took to themselves great credit, not without reason, in view of the provocation. At Versailles, however, their attack on the Illinois seemed an unpardonable offence, and the next ship from France brought a letter from the colonial minister declaring that the Outagamies must be effectually put down, and that "his Majesty will reward the officer who will reduce, or rather destroy, them."[339]
