British and American forces fought outside New Orleans, Louisiana, on 8 January 1815, although the Treaty of Ghent had been signed in Belgium on 24 December 1814. News crossed the Atlantic too slowly to prevent the battle, and the treaty had not yet been ratified. Andrew Jackson's victory nevertheless transformed American politics and memory.

The apparent victory after peace produced legends, broadside ballads and patriotic verse that often obscured the chronology. Later songs and poems turned Jackson and the frontier riflemen into national symbols, demonstrating how delayed information can become more culturally powerful than diplomatic fact.
