Early in February, three hundred men under Dorvilliers were sent by Frontenac to surprise the Iroquois in their hunting-grounds. When they were a few days out, their leader scalded his foot by the upsetting of a kettle at their encampment near Lake St. Francis; and the command fell on a youth named Beaucour, an officer of regulars, accomplished as an engineer, and known for his polished wit. The march through the snow-clogged forest was so terrible that the men lost heart. Hands and feet were frozen; some of the Indians refused to proceed, and many of the Canadians lagged behind. Shots were heard, showing that the enemy were not far off; but cold, hunger, and fatigue had overcome the courage of the pursuers, and the young commander saw his followers on the point of deserting him. He called them together, and harangued them in terms so animating that they caught his spirit, and again pushed on. For four hours more they followed the tracks of the Iroquois snow-shoes, till they found the savages in their bivouac, set upon them, and killed or captured nearly all. There was a French slave among them, scarcely distinguishable from his owners. It was an officer named La Plante, taken at La Chine three years before. "He would have been killed like his masters," says La Hontan, "if he had not cried out with all his might, 'Miséricorde, sauvez-moi, je suis Français'" [18] Beaucour brought his prisoners to Quebec, where Frontenac ordered that two of them should be burned. One stabbed himself in prison; the other was tortured by the Christian Hurons on Cape Diamond, defying them to the last. Nor was this the only instance of such fearful reprisal. In the same year, a number of Iroquois captured by Vaudreuil were burned at Montreal at the demand of the Canadians and the mission Indians, who insisted that their cruelties should be paid back in kind. It is said that the purpose was answered, and the Iroquois deterred for a while from torturing their captives.
