Skipwith was elected to serve in the Louisiana State Senate where he served as that body's second President. In December 1814, during the War of 1812, Magloire Guichard and Skipwith sponsored a legislative resolution to grant amnesty to "the privateers lately resorting to Barataria, who might be deterred from offering their services for fear of prosecution." This led to Jean Lafitte and his men joining in the defense of New Orleans during the Battle of New Orleans, when the city was attacked by British forces.
