In the year 1731, he was appointed a runner, to assist in collecting an army to go against the Cotawpes, Cherokees and other southern Indians. A large army was collected, and after a long and fatiguing march, met its enemies in what was then called the "low, dark and bloody lands," near the mouth of Red River, in what is now called the state of Kentucky. [Footnote: Those powerful armies met near the place that is now called Clarksville, which is situated at the fork where Red River joins the Cumberland, a few miles above the line between Kentucky and Tennessee.] The Cotawpes [Footnote: The Author acknowledges himself unacquainted, from Indian history, with a nation of this name; but as 90 years have elapsed since the date of this occurrence, it is highly probable that such a nation did exist, and that it was absolutely exterminated at that eventful period.] and their associates, had, by some means, been apprized of their approach, and lay in ambush to take them at once, when they should come within their reach, and destroy the whole army. The northern Indians, with their usual sagacity, discovered the situation of their enemies, rushed upon the ambuscade and massacred 1200 on the spot. The battle continued for two days and two nights, with the utmost severity, in which the northern Indians were victorious, and so far succeeded in destroying the Cotawpes that they at that time ceased to be a nation. The victors suffered an immense loss in killed; but gained the hunting ground, which was their grand object, though the Cherokees would not give it up in a treaty, or consent to make peace. Bows and arrows, at that time were in general use, though a few guns were employed.

From that time he was engaged in a number of battles in which Indians only were engaged, and that made fighting his business, till the commencement of the French war. In those battles he took a number of Indians prisoners, whom he killed by tying them to trees and then setting small Indian boys to shooting at them with arrows, till death finished the misery of the sufferers; a process that frequently took two days for its completion!

During the French war he was in every battle that was fought on the Susquehannah and Ohio rivers; and was so fortunate as never to have been taken prisoner.

At Braddock's defeat he took two white prisoners, and burnt them alive in a fire of his own kindling.

In 1777, he was in the battle at Fort Freeland, in Northumberland county, Penn. The fort contained a great number of women and children, and was defended only by a small garrison. The force that went against it consisted of 100 British regulars, commanded by a Col. McDonald, and 300 Indians under Hiokatoo. After a short but bloody engagement, the fort was surrendered; the women and children were sent under an escort to the next fort below, and the men and boys taken off by a party of British to the general Indian encampment. As soon as the fort had capitulated and the firing had ceased, Hiokatoo with the help of a few Indians tomahawked every wounded American while earnestly begging with uplifted hands for quarters.

The massacre was but just finished when Capts. Dougherty and Boon arrived with a reinforcement to assist the garrison. On their arriving in sight of the fort they saw that it had surrendered, and that an Indian was holding the flag. This so much inflamed Capt. Dougherty that he left his command, stept forward and shot the Indian at the first fire. Another took the flag, and had no sooner got it erected than Dougherty dropt him as he had the first. A third presumed to hold it, who was also shot down by Dougherty. Hiokatoo, exasperated at the sight of such bravery, sallied out with a party of his Indians, and killed Capts. Dougherty, Boon, and fourteen men, at the first fire. The remainder of the two companies escaped by taking to flight, and soon arrived at the fort which they had left but a few hours before.

In an expedition that went out against Cherry Valley and the neighboring settlements, Captain David, a Mohawk Indian, was first, and Hiokatoo the second in command. The force consisted of several hundred Indians, who were determined on mischief, and the destruction of the whites. A continued series of wantonness and barbarity characterized their career, for they plundered and burnt every thing that came in their way, and killed a number of persons, among whom were several infants, whom Hiokatoo butchered or dashed upon the stones with his own hands. Besides the instances which have been mentioned, he was in a number of parties during the revolutionary war, where he ever acted a conspicuous part.

The Indians having removed the seat of their depredations and war to the frontiers of Pennsylvania, Ohio, Kentucky and the neighboring territories, assembled a large force at Upper Sandusky, their place of general rendezvous, from whence they went out to the various places which they designed to sacrifice.

Tired of the desolating scenes that were so often witnessed, and feeling a confidence that the savages might be subdued, and an end put to their crimes, the American government raised a regiment, consisting of 300 volunteers, for the purpose of dislodging them from their cantonment and preventing further barbarities. Col. William Crawford and Lieut. Col. David Williamson, men who had been thoroughly tried and approved, were commissioned by Gen. Washington to take the command of a service that seemed all-important to the welfare of the country. In the month of July, 1782, well-armed and provided with a sufficient quantity of provision, this regiment made an expeditious march through the wilderness to Upper Sandusky, where, as had been anticipated, they found the Indians assembled in full force at their encampment, prepared to receive an attack.

As Col. Crawford and his brave band advanced, and when they had got within a short distance from the town, they were met by a white man, with a flag of truce from the Indians, who proposed to Col. Crawford that if he would surrender himself and his men to the Indians, their lives should be spared; but, that if they persisted in their undertaking, and attacked the town, they should all be massacred to a man.
