Battle of New Orleans, April 24, 1862


Before the Civil War, Louisiana was a major slave state. In 1860, 47% of the population was in slavery. However Louisiana also had one of the largest free black populations in the United States.[1] 

On January 26, 1861, Louisiana seceded from the United States. However sections of the state were strongly Union, so the U.S. Congress made those parts a state and allowed it to have a governor and U.S. Congressmen.[1] 

Louisiana formed 265 military units for the Confederacy[2] and 23 for the Union.[3] [4]
