Which French privateer assisted Andrew Jackson at the Battle of New Orleans?

Jean Lafitte was the French privateer who assisted Andrew Jackson at the Battle of New Orleans. Lafitte and his Barataria-based men supplied valuable artillery expertise, weapons, ammunition, and manpower to the American defense in Louisiana.

Lafitte had operated a profitable smuggling and privateering network in Barataria Bay, near New Orleans. In September 1814, U.S. forces attacked his base and seized much of his fleet. When British agents later offered him money and a position if he supported their campaign against New Orleans, Lafitte instead warned American authorities and negotiated with Jackson.

In exchange for a pardon, many of Lafitte’s men joined the defense. Some served in artillery units, while others entered the militia or helped man vessels. Their battlefield experience was especially useful because New Orleans initially lacked trained defenders and adequate military organization.

The battle was fought on January 8, 1815, after the Treaty of Ghent had already been signed but before news of the treaty reached the armies. Jackson’s victory made Lafitte a famous, though controversial, ally rather than a conventional officer.
