All the same de Callières inaugurated his government by an honourable and successful piece of statesmanship. Seeing that there was now by the treaty of Ryswick (September 20, 1697), a temporary peace, at least, between the English and the French, he desired to make all the Indians of the north of America share in it—a no easy task, since the English desired to keep the Iroquois in hostility toward the French still. It was not for nearly two years after the overtures had commenced that peace was definitely settled. In March, 1699, three Iroquois deputies had arrived at Montreal before the death of Frontenac, and besides desiring an exchange of prisoners, asked de Callières to conclude peace at Albany. According to La Potherie, they asked for the Jesuits Bruyas and Lamberville, for whom they had great esteem, to be sent with M. de Maricourt for this purpose.

But de Callières, seeing through their ruse, that they wanted their prisoners while they still would keep the French captives with the Five Nations, firmly told them that the peace had to be signed at Montreal and nowhere else. On July 18, 1700, a further embassy came to Montreal with six Iroquois ambassadors, two from the Onondagas and four from the Senecas, to pray the governor to send Father Bruyas and de Maricourt, and in place of Father Lamberville, then in France, the interpreter, Joncaire, who had married an Iroquois squaw and whose valour was much respected by them, so that they might seek the French prisoners themselves. The governor consented on condition that they should bring back with the prisoners the ambassadors from Onneyout and Gogogouen, with full powers to treat of peace. He did not speak of the others of the Five Nations, e. g. the Agniers (Mohawks), who living near Albany, were under English influence. The mission of Father Bruyas, de Maricourt and Joncaire was successful, and towards the beginning of September they returned with nineteen deputies from the country, and but ten French prisoners, the rest either not being able to secure their liberty, or preferring to adopt the Indian life.

On September 8th de Callières received the embassy in solemn audience, when a provisional treaty of peace was signed by all the chiefs of the tribes present. It was witnessed by the governor, intendant, the ecclesiastical, civil and military authorities, the Hurons, the Ottawas, the Abenakis and the Christian Iroquois from the missions of the Mountain and of Sault St. Louis. The month of August of the following year was appointed by de Callières for the final treaty to be signed at Montreal, for he aimed at a general alliance with all the Five Nations, to be preceded by a complete exchange of prisoners. But would they ever return? The governor with his calm confidence determined that they should and for this purpose he made use of the missionaries. To prepare the minds of the people for peace, Father de Bruyas, de Maricourt and Joncaire were again sent to Onondaga; Father Enjalran and M. de Courtmanche to the nations above. Among the Abenakis, Father Vincent Bigot, the Recollect Fathers in Acadia, and Father Carheil at Michillimackinac, and others, were also to promote the same great universal peace.

At last the great assembly opened at Montreal on July 25, 1701. Never had there been seen such a representative union of the Five Nations. There were present the Abenakis with Father Vincent Bigot; the Iroquois with Father Bruyas; the Hurons with Father Garnier; the Ottawas with Father Enjalran, and the Illinois and Miamis with the intrepid voyageur, Nicolas Perrot. There were also the Christian Indians from the mission settlements of Sault St. Louis, the Mountain, Lorette, Sillery, of the River St. Francis and St. Francis de Sales with the Algonquins, the Micmacs and many tribes from the west.

But all was not harmony; there were mutual recriminations and disputes and it looked as if the treaty would never be signed, had not the Rat, the Huron Chief Kondiaronk, swayed the minds of the assembly with his eloquence and saved the peace. It was he who had formerly broken the peace between Denonville and the Iroquois, but now he was to win the undying gratitude of the French by his masterly and tragic espousal of their cause. The historian Charlevoix speaking of Kondiaronk (Vol. 2, p. 278) says: "Never had savage more merit than he, a more noble character, more valour, more prudence and more discernment in knowing how to treat with others." He was so eloquent that he aroused the plaudits even of his enemies and those jealous of him; since he had so much intelligence and animation, he made such lively and witty repartees, and had ever such ready reply, that he was the only man in Canada who could cope with the Count de Frontenac. When the latter wished to divert his officers he invited the Rat to his table. On his side the Rat knew how to esteem his French contemporaries. "Among the French," he said, "I know only two men of sense, the Count de Frontenac and Father Carheil," the latter being the Jesuit missionary who had converted him, and for whom he had the tenderest veneration.

Amid the havoc of dissentient voices at the great assembly, the Rat, though suffering from great feebleness of health, demanded to be heard. He was accorded an arm chair in the middle of the assemblage and all drew near to hear him. "He spoke long," says Charlevoix, "and was listened to with infinite attention. He explained the necessity of peace, of the advantages accruing therefrom for the country in general and each tribe in particular." The emotion he aroused was great and he drew forth unanimous applause. But the brave orator had outpassed his strength and his once vigorous constitution was now broken. At the end of the discourse he was taken, a dying man, to the Hôtel-Dieu, where he died the following night with sentiments of religious fervour and fortified by the sacraments of the church.

His funeral obsequies were magnificent. He was buried in the parish church and over his tomb was inscribed:

"Ci-gît le Rat, Chef Huron"
(Here lies the Huron Chieftain, the Rat.)

Four days after his death, on August 14th, the ceremony of the signing of the peace took place. High placed on a dais sat the representative of France, her lieutenant governor, M. de Callières, having by his side the intendant, Champigny, the governor of Montreal, de Vaudreuil, and principal officers of the county. Before him passed in single file all the contracting nations. Then took place the exchange of prisoners. The customary calumet of peace, was offered the Governor de Callières, who after smoking it passed it on till it had circulated among the encircling throng of Indian deputies. Thirty-eight of these then signed singly, each his own peculiar mark, a bear for the Agniers (Mohawk), a spider for the Onnontagues (Onondagas) and the Tsonnontouans (Senecas), a beaver for the Hurons, a caribou for the Abenakis, for the Ottawas a hare, etc. Then resounded the Te Deum of thanksgiving and the assemblage dispersed to be regaled by a grand and monstrous banquet, with salvos of artillery and fireworks, to terminate this auspicious day.
