The delays inseparable from the transportation of necessary supplies through an uninhabited country, infested by an active enemy peculiarly skilled in partisan war, unavoidably protracted the opening of the campaign until near midsummer. Meanwhile several sharp skirmishes took place, in one of which a few white men were stated to be mingled with the Indians.

On the 8th of August (1794) General Wayne reached the confluence of the Au Glaize, where he threw up some works of defense and protection for magazines. The richest and most extensive settlements of the western Indians lay about this place.

The mouth of the Au Glaize is distant about thirty miles from the post occupied by the British, in the vicinity of which the whole strength of the enemy, amounting, according to intelligence on which General Wayne relied, to rather less than 2,000 men, was collected. The Continental legion was not much inferior in number to the Indians, and a reinforcement of about 1,100 mounted militia from Kentucky, commanded by General Scott, gave a decided superiority of strength to the army of Wayne. That the Indians had determined to give him battle was well understood, and the discipline of his legion, the ardor of all his troops, and the superiority of his numbers, authorized him confidently to expect a favorable issue. Yet, in pursuance of that policy by which the United States had been uniformly actuated, he determined to make one more effort for the attainment of peace without bloodshed. Messengers were dispatched to the several hostile tribes who were assembled in his front, inviting them to appoint deputies to meet him on his march, in order to negotiate a lasting peace.

On the 15th of August (1794) the American army advanced down the Miami, with its right covered by that river, and on the 18th arrived at the rapids. Here they halted on the 19th, in order to erect a temporary work for the protection of the baggage and to reconnoiter the situation of the enemy.

The Indians were advantageously posted behind a thick wood, and behind the British fort.

At 8 in the morning of the 20th the American army advanced in columns, the legion with its right flank covered by the Miami. One brigade of mounted volunteers, commanded by General Todd, was on the left; and the other, under General Barbee, was in the rear. A select battalion, commanded by Major Price, moved in front of the legion, sufficiently in advance to give timely notice for the troops to form in case of action.

After marching about five miles Major Price received a heavy fire from a concealed enemy, and was compelled to retreat.

The Indians had chosen their ground with judgment. They had advanced into the thick wood in front of the British works, which extends several miles west from the Miami, and had taken a position rendered almost inaccessible to horse by a quantity of fallen timber which appeared to have been blown up in a tornado. They were formed in three lines, within supporting distance of each other; and, as is their custom, with a very extended front. Their line stretched to the west, at right angles with the river, about two miles, and their immediate effort was to turn the left flank of the American army.

On the discharge of the first rifle, the legion was formed in two lines, and the front was ordered to advance with trailed arms and rouse the enemy from his covert at the point of the bayonet; then, and not until then, to deliver a fire, and to press the fugitives too closely to allow them time to load after discharging their pieces. Soon perceiving the strength of the enemy in front, and that he was endeavoring to turn the American left, the general ordered the second line to support the first. The legion cavalry, led by Captain Campbell, was directed to penetrate between the Indians and the river, where the wood was less thick and entangled, in order to charge their left flank; and General Scott, at the head of the mounted volunteers, was directed to make a considerable circuit, and to turn their right flank.

These orders were executed with spirit and promptitude, but such was the impetuosity of the charge made by the first line of infantry, so entirely was the enemy broken by it, and so rapid was the pursuit that only a small part of the second line and of the mounted volunteers could get into action. In the course of one hour the Indians were driven more than two miles through thick woods, when the pursuit terminated within gunshot of the British fort.
