Pouchot went with an officer to the bastion next to the river and listened anxiously to the firing which told him that his reinforcements were in conflict with the English and trying to cut a way through to the beleaguered stronghold. For a time he heard the sound of battle and then all was still. At length a friendly Indian who had passed unnoticed through the lines of the English came to the French commander. “Your men are defeated,” he said in substance. Pouchot would not believe him. Nevertheless it was true and this fact was the death-blow to French hold of Fort Niagara. In the articles of surrender shortly afterward drawn up, it was specially stipulated that the French should be protected from the Indians as they feared that the massacre of Fort William Henry would be avenged upon them. Johnson was able to restrain his lawless allies and, though the fort was given to pillage, no French lives were taken after the surrender.
From this time until the close of the American War of Independence the post remained in English hands. During the Pontiac War of 1763 the Indians made an unsuccessful attack upon it and its garrison frequently took part in small skirmishes with lurking unfriendly Senecas in the woods around the post. Heavily garrisoned by the English during the Revolution, it served as a base for the war parties which frequently devastated the State of New York. Both the expedition led by Colonel Butler, which culminated in the massacre at Wyoming, New York, in 1778, and that which laid waste Cherry Valley in the same year, started from Fort Niagara.
That the American forces were not unaware of the evil dominance of this post on the far western border of New York, we cannot doubt, as one of the objects of the expedition led by General Sullivan against the Indians in 1779 was the destruction, if possible, of Niagara; but this campaign ended only with the destruction of Indian villages. Subsequent to the declaration of peace between England and America, the point was held by English troops until it was taken over by an American garrison in 1796, probably having the distinction of being the last post surrendered by the English to the Americans in the United States. In 1799, in anticipation of another Indian war, the post was heavily reinforced.
