I realize this is an unpleasant subject, but thinking of battles like Gettysburg, with 50,000 killed in three days, it occurs to me to ask how on earth did they bury all those bodies? Plus, it would have to be done quickly to avoid the spread of disease. Who buried them? Did they use prisoners, free slaves, or did they hire locals? Correction: deleson1 pointed out to me that the 50,000 number I cited above was in error. That total includes wounded and captured. Here is a breakdown from Military History Online: Union: Killed - 3, 155Wounded 14, 530Missing: 5, 365Total: 23,040 Confederate:Killed: 2,600 - 4,500Wounded: 12,800Missing: 5,250Total: 20,650 - 25,000 Total Confederate casualties have been estimated to be as great as 28,000. It is usually agreed that total Confederate casualties numbered at least 1/3 of Lee's army. Casualties generally included anyone who deserted, was captured, missing, wounded, or killed. In essence, if a soldier was not present during muster, he could likely be counted as a casualty.
