The turn of events that became known as the War of 1812 was America's second armed conflict with Britain. Following the success of the American Revolution and the establishment of the United States as an independent nation, the former colony again found itself at war with the powerful European nation. The conflict centered on infringements of American sovereignty at sea and the British navy's search, seizure, and attack of certain American merchant ships.
A local connection
In an effort to take control of the Great Lakes, and thereby cut off reinforcements and the flow of supplies to American forces, the British forces captured forts on Mackinac Island and later military forces in Detroit. Monroe's location (Known then as Frenchtown) in the Great Lakes made it vulnerable to attack given that the British and their allies had control over this waterway system, and left it the site of two major battles.
