On board the USS Minnesota in action during the assault on Fort Fisher, 15 January 1865. Landing on the beach with the assaulting party from his ship, S/man Bass advanced to the top of the sand hill and partly through the breach in the palisades despite enemy fire which killed and wounded many officers and men. When more than two-thirds of the men became seized with panic and retreated on the run, he remained with the party until dark, when it came safely away, bringing its wounded, its arms, and its colors.
