The Battle of New Orleans (8 January 1815) was the final major engagement of the War of 1812, fought between American forces under Major General Andrew Jackson and a British expeditionary force under General Sir Edward Pakenham. The battle took place southeast of New Orleans along the Mississippi River at Chalmette Plantation. American forces repelled a frontal assault by the British, inflicting disproportionate casualties and forcing a British withdrawal. The engagement occurred roughly two weeks after the signing of the Treaty of Ghent (24 December 1814), though neither side had received word of the peace settlement before the fighting began.

The outcome of the battle is not in dispute: American forces won a decisive tactical victory. British forces suffered approximately 2,000 casualties killed, wounded, or captured; American losses numbered fewer than 100. General Pakenham was killed in the assault. The British withdrew from the Louisiana coast within weeks.

Historical interpretation centers on several questions: the degree to which the battle influenced the final terms of the Treaty of Ghent (which had already been signed), the role of the victory in shaping American national mythology, and Jackson's conduct before and during the campaign - including his imposition of martial law in New Orleans and his use of irregular forces. Historians have also examined the contributions of free black soldiers, Native American allies (notably the Choctaw), and the privateer Jean Lafitte's men, whose roles are sometimes minimized or exaggerated depending on the account.

- Decisive moment in American history - Some historians and popular accounts treat the battle as having secured American sovereignty over the Louisiana Territory and the Mississippi River valley, arguing that a British victory could have reopened territorial questions despite the treaty. See battle-of-new-orleans-decisive-moment-viewpoint.

- Militarily irrelevant, symbolically formative - Others argue the battle had no effect on the war's outcome, since the treaty was already signed, but that it became foundational to Jacksonian-era American identity and nationalist mythology. See battle-of-new-orleans-symbolic-significance-viewpoint.

- Jackson's conduct as problematic - A distinct line of criticism focuses on Jackson's declaration of martial law, his arrest of a federal judge, and his treatment of some militia units, framing these as early evidence of authoritarian tendencies. See battle-of-new-orleans-jackson-conduct-viewpoint.

- Multicultural coalition emphasis - Some accounts center the battle as an example of effective multiracial and multi-ethnic military cooperation, highlighting the contributions of free black soldiers, Choctaw fighters, Creole militia, and Baratarian privateers. See battle-of-new-orleans-coalition-forces-viewpoint.

- Martial law and civil liberties - Jackson's imposition of martial law in New Orleans before the battle, and his refusal to lift it immediately after, resulted in the arrest of a Louisiana state legislator and a federal judge; the episode remains a documented legal and civil-liberties dispute. See battle-of-new-orleans-martial-law-controversy.

- Credit for the victory - The relative contributions of Jackson's regular troops, the free black battalions, the Choctaw allies, and Lafitte's privateers have been disputed in both popular and scholarly literature, with different accounts emphasizing different groups.
