It is always a good deal easier to march when the men sing, as it helps to keep time and puts pep into a column and makes the packs seem lighter. The officers see to it that the mouth organs get tuned up the minute a hike begins. At the end of each hour we came to a halt for the regulation ten minutes' rest. Troops in heavy marching order move very slowly, even with the music--and the hours drag. The ten minutes' rest though goes like a flash. The men keep an eye on the watches and "wangle" for the last second. We passed through two ruined villages with the battered walls sticking up like broken teeth and the gray moonlight shining through empty holes that had been windows. The people were gone from these places, but a dog howled over yonder. Several times we passed batteries of French artillery, and jokes and laughter came out of the half darkness. Topping a little rise, the moon came out bright, and away ahead the silver ribbon of the Souchez gleamed for an instant; the bare poles that once had been Bouvigny Wood were behind us, and to the right, to the left, a pulverized ruin where houses had stood. Blofeld told me this was what was left of the village of Abalaine, which had been demolished some time before when the French held the sector. At this point guides came out and met us to conduct us to the trenches. The order went down the line to fall in, single file, keeping touch, no smoking and no talking, and I supposed we were about to enter a communication trench. But no. We swung on to a "duck walk." This is a slatted wooden walk built to prevent as much as possible sinking into the mud. The ground was very soft here. I never did know why there was no communication trench unless it was because the ground was so full of moisture. But whatever the reason, there was none, and we were right out in the open on the duck walk. The order for no talk seemed silly as we clattered along the boards, making a noise like a four-horse team on a covered bridge. I immediately wondered whether we were near enough for the Boches to hear. I wasn't in doubt long, for they began to send over the "Berthas" in flocks. The "Bertha" is an uncommonly ugly breed of nine-inch shell loaded with H.E. It comes sailing over with a querulous "squeeeeeee", and explodes with an ear-splitting crash and a burst of murky, dull-red flame. If it hits you fair, you disappear. At a little distance you are ripped to fragments, and a little farther off you get a case of shell-shock. Just at the edge of the destructive area the wind of the explosion whistles by your ears, and then sucks back more slowly.
