I have a combined volume of "The Decisive Battles" and "The Cavalry", and yes, the pictures are wonderful. They were written only 45 years after the war so the original photographs were still in really great shape.
“You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live.” - John Galt
