Hull’s Invasion

On the morning of July 12, 1812 the Governor of Michigan and revolutionary war hero, William Hull, led the first ever U.S. invasion onto foreign soil. The American army moved into Upper Canada and proceeded to take over the town of Sandwich, without opposition.
Soon after, he issued a proclamation asking the residents of Canada to join the Americans under the threat of “slavery and destruction.”
Hull and his 2000 men set south towards Amherstburg, but on July 26, a messenger delivered news of a native attack on Fort Mackinac. This forced Hull to have second thoughts and halt his forthcoming attack on Amherstburg.
Hull decided to retreat back to Detroit when he received news that Brock and the British army would protect Amherstburg personally.
