Through the door at the end of the hall, Bushrod could see daylight. Gray and sullen it was, but daylight all the same. Through the years Bushrod had seen the dawn come to many fields, after many hard fights, and it was always a sacred moment to him--proof that the universe was still intact in spite of the blood on the ground, the hosts of Departed beginning their first day in eternity, the dead horses and broken gun carriages and scattered equipment--in spite of all the panoramic ruin of the battlefield so brutal and grotesque that it was a wonder God did not bury it in darkness forever--and with it the guilty living, who crept from their holes or their stiff blankets and looked about with astonishment on what they had done. But God never would bury it. He always seemed to want to start over again, whether out of anger or pity Bushrod could not say. And now here was another dawn, after another great fight, and once more God had permitted Bushrod Carter to live.

They had three cadences, these spectral drummers, which they called First Kings, Second Kings, and Revelations. Going into a fight, they went from one cadence to another with no apparent signal until the officers began to shout commands and men began to fall. Then the drummers began a solemn drill beat that Bushrod believed would be the muttering undertone of every nightmare he would ever have.

Then as Anna listened another sound began to rise within the first. It began as a low keening, like the wind in a bottle tree, almost indiscernible amid the guns. Yet it was there, and it grew and grew, gaining strength and timbre until suddenly a new note broke away and was taken up: a high weird quavering like nothing that Anna had ever heard, that peopled the smoke with an army of mourning phantoms. Anna had heard the men talk of this, too—the uncanny demon cry of the Rebel army going into the attack—and now here it was for real, echoing across violence and death for the last time in a wild crescendo that seemed to peak and yet peak again: descanting blood, crying lost youth and the loss of all dreams. One last time it shrilled out of the rolling smoke, then collapsed all at once into a maelstrom of voices—the deep snarling utterance of thousands of men in hell.
