behind AotW

This somewhat fuzzy photograph is of 2nd Lieutenant Walter Forward Jackson who was in command of his Company, “G” of the 11th Pennsylvania Reserves when he was killed in action at Turner’s Gap on South Mountain on 14 September 1862. He was about 20 years old. The photograph looks to have been printed in a book, but I haven’t yet found the volume. This copy was posted to his Findagrave memorial.
