During the War of 1812, American forces were primarily led by General Andrew Jackson. Jackson gained prominence for his leadership in key battles, particularly the Battle of New Orleans, which took place in early 1815 after the war had technically ended. His strategic military decisions and ability to unify troops from various backgrounds contributed to his success. Jackson's actions during the war helped propel him into the national spotlight, ultimately leading to his election as the seventh President of the United States in 1828.
