This sixth-plate tintype features a seated cavalry trooper wearing Union blue, his hat seated on the table next to him. He is attributed as being a member of the 7th Iowa Cavalry regiment based on the hat badge marked "7/crossed swords/L" (mirrored) for L Company of the 7th regiment. The trooper is armed with what appears to be a British 1821 Pattern heavy cavalry saber and a Colt Dragoon revolver. The 7th Iowa Cavalry was mustered in Davenport, Iowa in 1863 and served most of its time in the west, taking part in the battles of Killdeer Mountain and the Badlands against Native Americans. The tintype is mounted in a thermoplastic case molded with patriotic and floral motifs.
