American Civil War.
Here is a description of the state of things in the Confederate internment camp at Andersonville during the American Civil War, which, after all, did not happen so very long ago. “Over 30,000 prisoners were cooped up in a narrow space; there was no shelter from the sun or cold but what the men could improvise for themselves; every possible disease was rampant; the prisoners were largely naked; the dead were pitched into a ditch and covered with quicklime; the smell of the dreadful stockade extended for two miles.... The state of affairs was known, or might have been known, at Richmond, for Colonel Chandler, inspector-general of the Confederate army, inspected the camp, and reported upon its administration in no halting terms. ‘It is a place,’ he said, ‘the horrors of which it is difficult to describe—it is a disgrace to civilisation.’”
Of the prisoners returning from the South, Whitman writes: “The sight is worse than any sight of battlefield or any collection of wounded, even the bloodiest. There was (as a sample) one large boat load of several hundreds—and out of the whole number only three individuals were able to walk from the boat. Can those be men—those little, livid, brown, ash-streaked, monkey-looking dwarfs?” (Cambridge Magazine, August 26, 1916, Supplement “Prisoners,” p. iv.) In spite of such appalling horrors (worse than the atrocities of rage and fear and drink) the North and South became reconciled, and with the passing of war bitterness passed too. The South was hard pressed, supplies often ran out, and there was indifference at Richmond. And so the military bullies often got the upper hand, and their appetite for bullying grew with what it fed on. The North refused all exchanges. “The prisoners at Richmond, Belle-Isle, and Andersonville were the pawns in a great match, and had to be sacrificed to the rigour of the game.” (Spaight, l.c., p. 270.)
