After General Mansfield was mortally wounded, Gen. Alpheus Williams commanded the US Twelfth Corps and rode the battlefield after the fighting had ceased. In a letter to his daughters on September 22, 1862, he wrote that the number of dead horses was high and that they lay, like the men, in all attitudes. He singled out one beautiful milk-white horse that had died in so graceful a position that he wished for its photograph, with its legs doubled under and its arched neck turned to one side as if looking back to the ball-hole in its side, so lifelike that until one got to it, it was hard to believe the horse was dead. Alexander Gardner captured the photograph Williams wanted. The officer who rode this mount into combat was Colonel Henry B. Strong, commander of the 6th Louisiana Infantry. Strong was killed in this field and buried in a hollow south of the Dunker Church, where his men marked his grave with a wooden headboard. In the 1870s, his remains were reinterred in Washington Confederate Cemetery, ten miles north in Hagerstown, Maryland.
