Captain Jonathan Carver, a colonial officer, puts the killed and captured at 1500.

A French writer, whose work was published at Montreal, says that they were all killed, except seven hundred who were captured; but this is, of course, a gross exaggeration.

General Levis and Roubaud, who were certain to have made the best of the matter, acknowledged that they saw some fifty corpses scattered on the ground, but this does not include those murdered in the fort and camp.
Probably the total number killed was about two hundred, and besides these must be counted the two hundred prisoners carried off to be tortured by the Indians.

The greater portion of these were purchased from the Indians, in exchange for rum, by Vaudreuil, the governor at Montreal; but to the eternal disgrace of this man, he suffered many of them to be carried off, and did not even interfere when, publicly, in the sight of the whole town, the Indians murdered some of the prisoners, and, not content with eating them themselves, forced their comrades to partake of the flesh.

Bougainville, one of the aides-de-camp of Montcalm, was present, and testified to the fact, and the story is confirmed by the intendant Bigot, a friend of the governor.
The ferocity of the Indians cost them dear.
