So, Fort Wayne was not the fort that existed and played such a part in the War of 1812. It was built after the war. But, its site did play a role.
The one from the War of 1812 was known as Fort Detroit and later its name was changed to Fort Shelby.
The site of Fort Wayne consisted of a high sand mound with freshwater springs along the marshy waterfront of the Detroit River.
The opening shots of the War of 1812, however, were fired in the vicinity of the future Fort Wayne. Although war had not yet been declared, Michigan militiamen bombarded the town of Sandwich, Upper Canada (later annexed to Windsor).
Later in the war, British General Isaac Brock crossed the narrowest part of the Detroit River with troops and landed on the future Fort Wayne site before marching on Detroit. In the ensuing Siege of Detroit, American General William Hull, believing himself completely surrounded and outnumbered, surrendered Fort Detroit to the British without offering much resistance.
