Civil War photographic history books lot, old photos of forts, cavalry, navy, battles

Lot of four volumes from the Photographic History of the Civil War - not a complete set here, though each book seems to be complete in itself. Four books in this lot - The Opening Battles (book one) - The Cavalry (book four) - Forts and Artillery (book five) - The Navies (book six).

These have wear, and worn dust jackets. Former owner's name is marked inside. All are complete, text not marked up. So many interesting old photos here, I had no idea that there were so many photos from the Civil War period!
