New Orleans soon became a major source of troops, armament, and supplies to the Confederate States Army. Among the early responders to the call for troops was the "Washington Artillery," a pre-war militia artillery company that later formed the nucleus of a battalion in the Army of Northern Virginia. In January 1862, men from the free black community of New Orleans formed a regiment of Confederate soldiers called the Louisiana Native Guard. Although they were denied battle participation, the Confederates used the Guard to defend various entrenchments around New Orleans. Several area residents soon rose to prominence in the Confederate States Army, including P.G.T. Beauregard, Braxton Bragg, Albert G. Blanchard, and Harry T. Hays, the commander of the famed Louisiana Tigers infantry brigade which included a large contingent of Irish American New Orleanians.
