A plan of Oswego and Lake Ontario, 1756. French and Indian War (1754-63). Oriented with north to top. 

The name of ‘M.r McKeller’ appears to have been written in a different hand to that in which the map is drawn, and does not resemble the known signature of Patrick Mackellar. However, the map does appear to be in Mackellar's hand. 

Forts Oswego, George and Ontario are noted on the map as being above the level of Lake Ontario. The traders' houses, Hospital, Bolting House and Bake House, Carpenters' houses and Smith's shop are shown outside Fort George and the positions of the batteries and parallels outside the forts are marked. The ‘Road to the French Camp’ is marked running east of Fort Ontario. Numerous soundings are given for the mouth of the Ondaga River and for the area where it enters Lake Ontario.
