History

Fall of Detroit

On 16 August 1812, after a short siege, Brigadier General William Hull surrendered Detroit to British, Upper Canadian, and Indigenous forces. ^[1] The reaction of the American public and government officials was that of disbelief and fury. ^[2] For the first time since the American Revolutionary War, British forces occupied American territory.

End of the occupation

On 29 September 1813, the Army of the Northwest under the command of William Henry Harrison arrived in Detroit. ^[3] American control over Michigan was restored. ^{[4] [5]}
