NEW ORLEANS – Inside Louisiana’s Civil War Museum, battle flags line the walls. Uniforms, swords and long-barreled guns fill museum cases beside homespun knapsacks, dented canteens and tiny framed pictures of wives that soldiers carried into battle. In the back, there’s a collection devoted to Jefferson Davis, one-time president of the Confederacy formed by the Southern states which seceded from the United States in 1861, complete with his top hat and fancy shoes at the spot where his body once lay in state.
