Step-by-step explanation:
The famous quote attributed to Commodore Oliver Hazard Perry after the Battle of Lake Erie, during the War of 1812, is, "We have met the enemy and they are ours." This battle was a pivotal moment as it gave the United States control of Lake Erie.
The victory also enabled General William Henry Harrison to defeat the British and Indian forces at the Battle of the Thames, where the Indian confederation leader Tecumseh was killed, thus weakening Native American resistance.
