(Mass aboard the USS Ronald Reagan - photo in public domain taken by by Photographer's Mate 3rd Class Dominique M. Lasco - Feb/2006)
(NY 69th Regiment, taken some time during the US Civil War)
It strikes me how even 140 some odd years apart, the composure on the faces of the congregants is about the same. There seem to be some Confederate soldiers (prisoners I expect) in the foreground. There are also some ladies present, I expect wives of the commanding officers. But if anyone knows more about this latter photo, please tell me. I expect it might be a Matthew Brady.
