Not that I can add much after 1800 posts. Conduct their funeral under the Confederate Naval Ensign, or at least drape their caskets with it. That flag was well enough recognized on the Confederate Blockade runner Alabama--an ocean away--for the Union Navy to sink her. During WWI fallen enemy pilots were accorded their full military honors when buried by their opponents, extend that last touch of chivalry to these men killed in action.
The writer makes several errors in fact regarding the war, which I will leave for others to discuss, as I am sure they have. I will only make the observation that a neo-Yankee is far, far worse than any neo-Confeerate could be.
