Cool find. Obviously Not the same horse in question in the ongoing thread ...but he probably rode quite a few horses during the duration. A horse still 'reliable' in 1878 would probably be a youngster in 1864-65 so maybe one he rode when not in the active front but would still qualify as one he rode 'during the war'. Great find though! Newspapers.com find?
