At certain positions there were what appeared to be openings through the wire, but these were nothing less than man-traps which have been found serviceable in case of an enemy attack. In an assault men follow the line of least resistance when they reach the barbed wire. These apparent openings are V-shaped with the open end toward the enemy. The attacking troops think they see a clear passage-way. They rush into the trap and when it is filled with struggling men machine guns are turned upon them, and, as Shorty said, "You got 'em cold." That, at least, was the presumption. Practically, man-traps were not always a success. The intensive bombardments which precede infantry attacks play havoc with entanglements, but there is always a chance of the destruction being incomplete, as upon one occasion farther north, where, Shorty told me, a man-trap caught a whole platoon of Germans "dead to rights." "But this is wot gives you the pip," he said. "'Ere we got three lines of trenches, all of 'em wired up so that a rat couldn't get through without scratchin' hisself to death. Fritzie's got better wire than wot we 'ave, an' more of it. An' 'e's got more machine guns, more artill'ry, more shells. They ain't any little old man-killer ever invented wot they 'aven't got more of than we 'ave. An' at 'ome they're a-s'yin', 'W'y don't they get on with it? W'y don't they smash through?' Let some of 'em come out 'ere an' 'ave a try! That's all I got to s'y." I didn't tell Shorty that I had been, not exactly an armchair critic, but at least a barrack-room critic in England. I had wondered why British and French troops had failed to smash through. A few weeks in the trenches gave me a new viewpoint. I could only wonder at the magnificent fighting qualities of soldiers who had held their own so effectively against armies equipped and armed and munitioned as the Germans were. After he had finished drugging his trench pets, Shorty and I made a tour of the trenches. I was much surprised at seeing how clean and comfortable they can be kept in pleasant summer weather. Men were busily at work sweeping up the walks, collecting the rubbish, which was put into sandbags hung on pegs at intervals along the fire trench. At night the refuse was taken back of the trenches and buried. Most of this work devolved upon the pioneers whose business it was to keep the trenches sanitary.
