But swiftly now we are on the march again, pressing toward the sound of the Song. And soon the wounded begin to appear, making their way past us toward the rear by the side paths of the road on which we march; every moment their numbers increase until we find ourselves marching between two ghastly lines of wounded men: only a detachment from the growing company of the victims of the Song, only those who can walk. But there were gruesome sights in that procession of pain. Here a man holding up his hand across which a bullet has ploughed a bloody track; there one with a ragged hole through his cheek; then an officer leaning on two other men, both wounded, the ashy hue of death on his face and the blood streaming from his breast. This is no picture of the imagination. I am telling things that I saw, things that burned themselves into my memory; and I remember that every one of those wounded men whether his hurt were great or small, was pale as death and wore a fixed expression, not of terror but of stony despair. They all walked slowly and wearily and if you asked one of them, "How is the battle going?" you got the invariable answer, "Our regiment is all cut to pieces;" and they said it in a tone of tired reproach as though you ought to know and had insulted them by asking, or else with an inflection which meant, "Presently you will catch it yourselves." It was a procession of spectres and cold cheer it furnished for us, hurrying forward toward the ever-nearing and now frightful tones of the Song; yet I think the emotion uppermost in our minds was not precisely fear but a sort of awful curiosity: we burned to see as well as hear the dreadful mystery beyond the pines; the Song seemed to come from a deadly but luring siren whose call we must obey. But night was now coming fast and all the ways began to darken; and just when we expected to emerge into the heart of battle, as though an invisible conductor had suddenly raised his wand, as abruptly as it began the Song ceased and there was a great silence. We had heard though we had not seen the fight at Salem Church, a bitterly contested but drawn battle in which many hundreds of brave men fell. The Sixth Corps had begun to feel the weight of Lee's army.
