Or, upon entering the trench, they may meet the enemy's soldiers running out of their dugouts for hand-to-hand battle. The traverses are so narrow that the length of the rifle makes it a clumsy weapon, and the adversaries in modern war, whose guns carry twenty miles, engage hand to hand, using knives, bombs and even their fists. With discarded rifles and bombs lying about a trench, it is difficult to give quarter. For a prisoner who is down may pick up a rifle or a bomb and turn on his captor. It is not human savagery so much as conditions that has made the fighting so grim. Having established themselves in a certain section or sections of the trench, naturally the new occupants have the enemy on their right and left. That is, on one side of one of the winding traverses will be a German, and say on the other side a Frenchman. Neither sees the other's head, for both are hidden behind these walls of earth. If one starts around the corner, it means a bayonet or a bullet for him. To gain ground in a trench requires a superior supply of bombs. Any small package that will contain a high explosive would serve the purpose. Early in the war, bombs were made out of jam tins and bottles or any other receptacle which could be filled with an explosive and set off by a fuse. Later on, different varieties of manufactured bombs in great quantities appeared. There have been instances of five thousand being used in a single day over two hundred yards of trench. After throwing a bomb from the traverse, the offensive follows up the explosion by rushing along the traverse and catching the defender with a bayonet while he is _hors de combat_ from the effect of the explosion. While this orgy--characteristic of cave dwellers battling on a precipice in its ferocity--is proceeding, all is precision at the rear. As the caissons bring up the supplies of ammunition, the green-curtained motor ambulances speed on to the hospital with the wounded and the military police direct the congested traffic and keep watch for spies. VITAL LESSONS War is force, violence, killing. Whoever tries to disguise its character is a poor soldier and a poorer citizen. If you would avoid it, and if you would prepare for it, you must look at it as a fact, squarely in the face. Never has war been so savage as it is in this most progressive age in history. We had popular education, aseptic surgery, the wireless, and antitoxin, but war came nevertheless, and in the wake of Hague conferences and much preaching of internationalism. It came when the nations were supposed on account of the press and the telegraph to have been farther removed from parochialism than ever before, when more people in every nation in Europe knew the language of their neighbors than ever in history.
