Silently the five Brothers, again united and ready to fight to the death, gazed at one another as they lined up in the trench. That is they were silent as regards conversation, for they could not talk with their gas masks on, and the warning given by the lieutenant--the warning and the admonition to stand fast--had been the last words he uttered before he, too, donned the protecting device. And no sooner had the five Brothers and those about them begun to breathe through the chemicals that destroyed the terrible chlorine, than over it came rolling in a deadly, yellowish cloud. And yet it was far from silent in that hideous storm, for the very ground shook and trembled with the intensity of the gun-fire--the gun-fire not only of the Germans but the Allies as well. It was an attack in force, and the fire was of the fiercest. Protected somewhat by the trench, in which they were, nevertheless the members of the company to which our heroes belonged sustained several casualties. At one place a high explosive shell struck on the very edge of the trench, caving it in, and burying beneath tons of earth and stone the unfortunate Sammies stationed there. And the worst of it was that no adequate revenge could be taken just then--at least no revenge that was visible to the enraged comrades of the killed and wounded. For the orders were to stay in the trenches and repel the attack at first. Later the counter-attack on the part of the Americans would take place, and then it might be that the Huns would be made to pay dearly for their work. Jimmy looked through the grotesque goggles of his gas mask at his chums. If appearances went for anything they were on the alert and ready to jump over the top at the signal and fight to the death. But the word was delayed, for what, doubtless, were good military reasons. There was little that could be accomplished in firing one's rifle over the top of the trench. This was all right in the case of sniping, but for a general attack the work had to be done by the artillery, big and little. Later would come the rush in the open, or the standing fast to repel the attack of the gray hordes. And then the rifle fire of the infantry would tell. It was hard waiting--to be stuck down in what was, literally, a "mud hole," and stay there while, over one's head, shrilled and screamed the big shells, that must create untold havoc, damage and death in the rear. Fortunately, however, as was learned later, the Germans did not have the range accurately. They wasted much of their fire on unoccupied ground in the immediate rear of the American position, and it was only an occasional shell that landed near the trenches. So the position of our heroes was not as bad as at first they imagined.
