One of my favorite period accounts – from Adair, page 392-395.
A party of the Senekah Indians came to war against the Katahba, bitter enemies to each other. In the woods, the former discovered a sprightly warrior belonging to the latter, hunting in their usual light dress; on his perceiving them, he sprung off for a hollow rock, four or five miles distant, as they intercepted him from running homeward. He was so extremely swift, and skilful with the gun, as to kill seven of them in the running fight, before they were able to surround and take him. They carried him to their country in sad triumph: but, though he had filled them with uncommon grief and shame, for the loss of so many of their kindred, yet the love of martial virtue induced them to treat him, during their long journey, with a great deal more civility, than if he had acted the part of a coward. The women and children, when they met him at their several towns, beat and whipped him in as severe a manner as the occasion required, according to their law of justice, and at last he was formally condemned to die by the fiery tortures. It might reasonably be imagined that what he had for some time gone through, by being fed with a scanty hand, a tedious march, lying at night on the bare ground, exposed to the changes of the weather, with his arms and legs extended in a pair of rough stocks, and suffering such punishments on his entering into their hostile towns, as a prelude to those sharp torments for which he was destined, would have so impaired his health, and affected his imagination, as to have sent him to his long sleep out of the way of any more sufferings. Probably, this would have been the case with the major part of white people, under similar circumstances; but I never knew this with any of the Indians: and this cool-headed brave warrior did not deviate from their rough lessons of martial virtue, but acted his part so well, as to surprise and sorely vex his numerous enemies. For, when they were taking him unpinioned, in their wild parade, to the place of torture, which lay near to a river, he suddenly dashed down those who stood in his way, sprung off, and plunged into the water, swimming underneath like an otter, only rising to take breath till he made the opposite shore. He now ascended the steep bank; but though he had good reason to be in a hurry, as many of the enemy were in the water, and others running every way, like blood-hounds, in pursuit of him, and the bullets flying around him, from the time he took to the river, yet his heart did not allow him to leave them abruptly, without taking leave in a formal manner, in return for the extraordinary favours they had done, and intended to do him. He first turned his backside toward them, and slapped it with his hand; then moving round, he put up the shrill war whoo whoop, as his last salute, till some more convenient opportunity offered, and darted off in the manner of a beast broke loose from its torturing enemies. He continued his speed so as to run by about midnight of the same day, as far as his eager pursuers were two days in reaching. There he rested, till he happily discovered five of those Indians, who had pursued him — he lay hid a little way off their camp, till they were found asleep. Every circumstance of his situation occurred to him, and inspired him with heroism. He was naked, torn, and hungry, and his enraged enemies were come up with him. But there was now every thing to relieve his wants, and a fair opportunity to save his life, and get great honour, and sweet revenge, by cutting them off. Resolution, a convenient spot, and sudden surprize, would effect the main object of all his wishes and hopes. He accordingly creeped towards them, took one of their tomohawks, and killed them all on the spot. He then chopped them to pieces, in as horrid a manner, as savage fury could excite, both through national and personal resentment, — he stripped off their scalps, clothed himself, took a choice gun, and as much ammunition and provisions as he could well carry in a running march. He set off afresh with a light heart, and did not sleep for several successive nights, only when he reclined as usual a little before day, with his back to a tree. As it were by instinct, when he found he was free from the pursuing enemy, he made directly to the very place where he had killed seven of his enemies, and was taken by them for the fiery torture.
He digged them up, scalped them, burned their bodies to ashes, and went home in safety with singular triumph. Other pursuing enemies came on the evening of the second day to the camp of their dead people, when the sight gave them a greater shock, than they had ever known before. In their chilled war council, they concluded, that, as he had done such surprising things in his defence, before he was captivated, and since that, in his naked condition, and was now well armed, if they continued the pursuit, he would spoil them all, for he surely was an enemy wizard. And therefore they returned home.
