Final answer:
The Treaty of Ghent ended the War of 1812, but the Battle of New Orleans occurred after the signing of the treaty.
Step-by-step explanation:
The Treaty of Ghent officially ended the War of 1812. However, due to slow communication, the Battle of New Orleans occurred after the signing of the treaty. The British attacked New Orleans on January 8, 1815, while the treaty was signed on December 24, 1814.
