OK. When the Civil War Started in 1860 most of the states had volunteer militia units. These where call Lincoln's 90 day wonders for the North. The uniforms that they started the war with where the standard 1858 uniforms with the long coat for the regular Army and the Hardee Hat. Volunteer units where very different. They ranged from Zouaves, Chasseurs, Highlanders . Uniforms ranged from Gray for the Union to blue for Confederacy. At the first Bull Run you could not tell who was who on the battle field. By late 1862 uniforms where becoming the standard civil war uniform. The short sack coat, the forage cap. I would recommend the follow books. I hope these will help and you did good on those uniform.
