Some descriptions of tortures done by Iroquois against their enemies in French documents: Jesuit Relations.

"...the first thing they did was that one of them cut with a knife around his scalp, which he stripped off in order to carry away the hair...

After such treatment one would hardly believe that there could remain any sensation of life... He suddenly rises, he takes in his hands, which [68] were all in shreds, a firebrand, that he might not die as a captive, and that he might defend the brief liberty he had recovered a little while before death. The rage and the cries of his enemies redouble at this sight; they rush towards him with pieces of red-hot iron in their hands. His courage gives him strength; he puts himself on the defensive; he hurls his firebrands upon those who come nearest him; he throws down the ladders, to cut off their way, and avails himself of the fire and flame,

The blood that streamed down from his head over his entire body would have rent with pity a heart which had any remnant of humanity...

Some throw upon him coals and burning cinders...
his enemies pounce upon him, burn him anew, then throw him upon the fire. This invincible spirit, rising again from the midst of the flames, — all covered with cinders that were imbued in his blood, two flaming firebrands in his hands, — turns towards the mass of his enemies, to inspire them with fear once more before he dies. Not one is so hardy as to touch him; he makes a way for himself, and walks towards the Village, as if to set it on fire."
