There appears to be some confusion here over regimental designations. The 5th U. S. Colored Heavy Artillery originated as the 9th Louisiana (Colored) Regiment Infantry. The latter became the 1st Mississippi (Colored) Heavy Artillery, then the 4th U. S. Colored Heavy Artillery, and finally the 5th USCHA. That sounds clear enough, but if you check Dyer’s “Compendium,” it will tell you that the 9th Louisiana became both the 1st Mississippi CHA and the 63rd U. S. Colored Infantry. It is possible that elements of the 9th Louisiana became the 63rd USCT, but the bulk of the former served in the 5th USCHA. Thus the casualty figures for the 5th include losses at Milliken’s Bend, which were 4 officers and 124 enlisted men killed or died of wounds. The regiment’s battlefield losses during the remainder of the war were very small.
