Sergeant Hyman Ginsburg, going along at the head of his squad, got this notion quite well fixed in his mind. Then, though, he saw smoke jets issuing from bushes and trees on ahead of him where the ridges of the slope sharpened up acutely into a sort of natural barrier like a wall; and likewise for the first time he now heard the tat-tat-tat of machine guns, sounding like the hammers of pneumatic riveters rapidly operated. To him it seemed a proper course that his squad should take such cover as the lay of the land afforded and fire back toward the machine guns. But since the instructions, so far as he knew them, called for a steady advance up to within a few rods of the enemy's supposed position and then a quick rush forward, he gave no such command to his squad. Suddenly he became aware that off to the right the forward movement of the battalion was checking up. Then, all in an instant, men on both sides were falling back. He and his squad were enveloped in a reverse movement. It seemed too bad that the battalion should be driven in after suffering these casualties and without having dealt a blow in return for the punishment it had undergone. But what did it matter if, after all, they were being sacrificed vainly as the result of a hideous mistake at divisional headquarters? Better to save what was left. So far as he could tell, nobody gave the word to retire. He found himself going back at the tail of his squad where before he had been its head. Subconsciously he was surprised to observe that the copse from which they had emerged but a minute or two earlier, as he had imagined, was a considerable distance away from them, now that they had set their faces toward it. It did not seem possible that they could have left it so far behind them. Yet returning to it the men did not perceptibly hurry their steps. They retreated without evidences of disorder--almost reluctantly--as though by this very slowness of movement to signify their disgust for the supposed fiasco that had enveloped them, causing them to waste lives in an ill-timed and futile endeavour. Ginsburg reentered the covert of birches with a sense of gratitude for its protection and let himself down into the trench. He faced about, peering over its rim, and saw that his captain--Captain Griswold--was just behind him, returning all alone and looking back over his shoulder constantly. Captain Griswold was perhaps twenty yards from the thicket when he clasped both hands to the pit of his stomach and slipped down flat in the trampled herbage. In that same moment Ginsburg saw how many invisible darting objects, which must of course be machine-gun bullets, were mowing the weed stems about the spot where the captain had gone down. Bits of turf flew up in showers as the leaden blasts, spraying down from the top of the ridge, bored into the earth.
