The siege of Fort Meigs took place in late April to early May 1813 during the War of 1812 in northwestern Ohio, present-day Perrysburg. A small British Army unit with support from Indians attempted to capture the recently constructed fort to forestall an American offensive against Detroit, and its Fort Detroit in the Great Lakes region which the British from the north in Canada had captured the previous year. An American sortie and relief attempt failed with heavy casualties, but the British failed to capture the fort and were forced to raise the siege.
