In the first unqualified defeat of a British naval squadron in history, U.S. Captain Oliver Hazard Perry leads a fleet of nine American ships to victory over a squadron of six British warships at the Battle of Lake Erie during the War of 1812.
The battle was closely contested for hours, and Perry's flagship Lawrence was reduced to a defenseless wreck. He then transferred to the Niagara and sailed directly into the British line, firing broadsides and forcing the British to surrender. Perry had won a complete victory at the cost of 27 Americans killed and 96 wounded; British casualties were 40 dead and 94 wounded. After the battle, Perry sent a famous dispatch to U.S. General William Henry Harrison that read, "We have met the enemy, and they are ours." The Battle of Lake Erie forced the British to abandon Detroit, ensuring U.S. control over Lake Erie and the territorial northwest.
