How is it done? Simply a matter of training and careful preparation. Every man is rehearsed in his work until he can do it perfectly, quickly and without noise. Materials are carefully checked up and distributed and, each man having a certain specified task and no other, there is no confusion or blundering. They all know that, when a flare goes up near by, they must "freeze" in whatever position they may be. Movements of any kind would be sure to discover them to the enemy lookout, but lacking that movement it is a hundred-to-one shot they will be undetected.
There have been a good many instances where a flag has been planted by the enemy, on his parapets or inside his wire, with a challenge to any one to come over and get it. There was one such opposite our position. Many stories had been told about that flag: The Brandenburgers had it first, then the French got it and passed it along to the English, who relieved them; then the Prussians took it away from the British and had held it ever since; for about a year, in fact. We could see it, plainly enough; a dark blue affair with some sort of a device in yellow in the center. I often noticed it from our position back at Sniper's Barn and had some rather hazy ideas about going over after it.
One dark rainy night in November, a man in the section named Lucky announced that he was going over to Fritz's line to try to locate a new machine-gun emplacement which we had reason to believe had been recently constructed. He slipped over the parapet where a road ran through our lines and those of the enemy. It was only about seventy yards across at this point.
Working his way through our wire, he crawled along the side of the old disused road, there being a shallow ditch there which afforded a little concealment. The flares were going up frequently and progress was, of course, very slow. At one place the body of a soldier was lying in the ditch and, in trying to roll it out of the way, he pulled off one of the feet. By creeping along, inch by inch, he finally reached the enemy's wire and spent about an hour working through it. Then crawling along the outside of the parapet, stopping often to listen, he soon found the loophole of the new gun emplacement. Taking a sheet of paper which he had brought for the purpose, he fastened it directly below the loophole where it would be in plain sight from our lines but invisible to the occupants of the place. His work done, he was about to start back when he happened to think of that flag and concluded to have a try for it. It was probably a hundred yards or more down the trench from where he then was and it required the utmost care to avoid making a noise as the front of the parapet, as is always the case, was thickly strewn with tin cans and rubbish of all sorts. Lucky had been a big game hunter in Canada, however, and had even stalked the wily moose which is about the last word in "still hunting," so he managed to negotiate the distance without detection and finally reached the flag.
