Known as "Merrells Black horse". My g-g-g-grand father was in the 2 MSM Cav. I have a image of a soldier in the 2nd. He is wearing a shell jacket with fancy piping on the front. I believe he was in comapany D. His family owns his pistol and holster. The holster is stamped "MH" in the place of the regulation "U.S."on the closing flap. Some companies in the 2nd carried two Colt navy pistols. The sword was also stamped with the unit desegnation It was a "Solgien " made blade and was an early issue. They sold the sword. The soldier I believe named William Jackson is buried in a cow path on the family farm in Clarence Mo.
