Leger’s report only 200 of them escaped. Butler estimated the total American casualties in killed, wounded, and prisoners, at 500, and, according to American accounts, the total was about 400. The white casualties on the British side were very small, but the casualties among the Indians seem to have numbered from 60 to 100. While the engagement was going on, a sortie was made from the fort, and it was probably news of this movement, coupled with the Indian losses, which put an end to the fight at Oriskany. Bird, the commander of the post at the lower landing-place, had been misled by a rumour that Johnson was hard pressed, and led out his men to support him, leaving the post undefended. Meanwhile, Willett at the head of 250 men marched out of the fort, apparently in ignorance of the ambuscade and designing to join hands with Herkimer’s force. Willett found the post practically deserted, mastered it, and carried off its contents, eluding an attempt which St. Leger made to cut him off on his return to the fort.[130] This ended the day’s work. Herkimer’s force had been blotted out, but it must have become increasingly evident that St. Leger’s men and resources were hopelessly inadequate for the task which had been set him, to force his way to Albany. [Sidenote: St. Leger fails to take Fort Stanwix and retreats to Oswego.] After the battle of Oriskany, St. Leger summoned the fort to surrender, but without effect. He continued the siege, but made little or no impression upon the defences. On the night of the 10th of August Willett made his way out of the fort, reached Fort Dayton, and went on to Albany where he met Benedict Arnold who had been charged with the duty of relieving Fort Stanwix. Arnold gathered troops for the purpose and in the meantime, with his usual cleverness, contrived to send on rumours which caused alarm in the British camp. A thousand men were reported to be coming, then 2,000, then 3,000, and Arnold’s own name may well have been a potent source of apprehension. The Indians, already depressed by their losses at Oriskany, and by the prolonging of the siege, became more and more out of hand, deserting, marauding, and spreading exaggerated tales; and at length, on the 22nd or 23rd of August, St. Leger beat a hasty retreat by night, leaving behind him most of his stores and guns, and returned to Oswego, whence he went back to Montreal and on to Lake Champlain in the wake of Burgoyne’s army. Joseph Brant took a less circuitous route. When St. Leger retreated from Fort Stanwix, Brant made one of his marvellous flying marches down the Mohawk Valley: and, after passing for over a hundred miles through the heart of the enemy’s country, which was also his own, in two or three days’ time joined Burgoyne’s force on the banks of the Hudson river.
