CAPTAIN LOUIS A. SNAER, Co. B., 73rd U.S.C.T., holds the distinction of being the sole Black Officer on the Blakeley Battlefield. Snaer was considered a free person of color in New Orleans upon his joining the Louisiana Native Guards in 1862. At the final charge at Blakeley he received a shell wound in his left foot and was treated for six days in the Field Hospital near Fort Blakeley. Colonel Merriam said about Snaer, "Captain Snaer fell with a severe wound at my feet as I reached the line. He refused to sheathe his sword or to be carried off the field . . . No braver officer has honored any flag." Snaer moved to California and died there in 1917 at the age of 75.
