This piece is titled, “A mounted view of Niagara fort taken by Sir William Johnson on the 25th of July 1759.  Drawn on the spot, 1758.” It is a print of the original done by Johnson (1715-1774). In 1736, Johnson began working for Peter Warren, managing his estate which was located in New York’s Mohawk Valley. Since he learned the Mohawk language and customs he was appointed as the British Agent to the Iroquois. In 1756 he became the British Superintendent of Indian Affairs for the Northern Colonies. During the French and Indian War he commanded Iroquois and British militia involved in the battles at Lake George and the capture of Fort Niagara in 1759.
