English: Newspaper caption "Germans Sneaking Back Underground Bomb This photograph shows German soldiers sneaking back from a tunnel which led them near the French trenches. A score or more of them dug their way in the direction in which their guns pointed, just in front of the hutt of the tree seen in the background, all the way. a quarter of a mile or more, to the French trenches and there planted bombs that could be touched off by electrity when the Frenchmen could lured to the ground. The two men coming from the trenches were the leaders of twenty more, yet in the deep, dark hole. They had to sneak back very quietly, keeping out of sight so the enemy would not see them coming from the hole. Their guns were left in place that the French might think a man was behind each. In fact, this particular trench might have been taken while the Germans were digging underground, had the enemy not known it."
