Final answer:
Major General Andrew Jackson led the U.S. forces to victory at the Battle of New Orleans, which took place on January 8, 1815, after the Treaty of Ghent had been signed. This battle highlighted Jackson's military leadership and significantly raised his national profile.
Step-by-step explanation:
At the Battle of New Orleans in 1815, Major General Andrew Jackson led U.S. forces to a decisive victory, showcasing his military prowess. Despite the Treaty of Ghent signifying the end of the War of 1812, the news had not yet reached the battlefield due to slow communication. Facing Jackson's well-prepared defenses, the British force, composed of Napoleonic War veterans, suffered a devastating defeat on January 8, with over 2,000 casualties.
Jackson's triumph at New Orleans solidified his status as a national hero, contributing to his later role as the head of the new Democratic Party and ultimately propelling him to become the seventh President of the United States. The battle's impact extended beyond its military significance, shaping the political landscape and Jackson's legacy in American history.
