ort Niagara was not always an American fortification. Located at the mouth of the Niagara River on Lake Ontario, it was originally built by the French in 1749 and then captured by Sir William Johnson for the British in 1759. By 1796 Fort Niagara was in the hands of the Americans as the result of negotiations settled by Jay's Treaty. This view is of Sir William Johnson's restored Council chamber at Fort Niagara (C.J. Humber Collection)

.The population of Upper Canada in 1792 was upwards of 20,000. On the Grand River in the Niagara region stood Mohawk Village. Elizabeth Simcoe's 1793 sketch of this quaint Indian community depicts the now famous Mohawk Chapel, which stands today as the oldest Protestant church in Ontario (courtesy/The Weir Foundation/Queenston, Ontario); 2.Following the Treaty of Paris, 1783, Fort Detroit fell into American hands but was held by the British for some thirteen years as security for safe treatment of the Loyalists. Jay's Treaty unconditionally returned Fort Detroit, viewed in this 1796 sketch, to the United States (NMC/ ).
