Among their friends the five Khaki Boys numbered the "Twinkle Twins," otherwise John and Gerald Twinkleton, two aviators, whose cousin, Emile Voissard, was known as the "Flying Terror of France." He was more than an ace, and it was in helping him that Jimmy won the reward. There was, too, Jimmy's friend Margaret, of Buffalo, but he had small hope of seeing his "girl" in those strenuous war days. Of course boys like the five Brothers could not progress as they had and not make enemies. The very fact that Jimmy, Roger and Franz were sergeants, while Bob and Ignace were corporals was enough to cause some jealous feelings among the squads they often commanded. And even in camp this had been shown, before they were promoted. There was one young soldier, Private Bixton, who acted very despicably toward the five friends until he was sent to a military prison, mainly through the instrumentality of Jimmy and his chums. For Bixton was a scoundrel, as well as a deserter. So, it can be seen, the five friends did not have it altogether easy. They fought hard, and they were wounded more than once, but not seriously enough to keep them long away from the firing line. And now, after having fought hard and been given a short leave of absence, part of which they had spent in the old German dugout, the Khaki Boys are again in trouble, caused by the collapse of the underground place when the big shell or the bomb exploded. Putting aside, for the moment, all thought of trying to dig their way out of their underground prison, the Khaki Boys proceeded to do what they could for the unfortunate Iggy. Their flashlights gave considerable illumination to the otherwise dark hole, and by looking around Jimmy and the others saw what had happened. The shell, bomb, or whatever it was, must have landed squarely on top of the dugout. And though this top proper, being made of concrete, was some distance underground, it had been made to collapse as one might push in the end of an egg. The roof of the dugout was depressed while the walls still stood upright, though much cracked. The place was filled with débris. It was owing to the fact that the strong, thick walls held that the boys' lives were not at once crushed out. They had been along the edges, and not standing in the middle, when the crash came. "Lift him over to one side, and we'll see if we can tell what's the matter with him," suggested Roger. Accordingly they scraped as much dirt and débris off the Polish lad as possible, and then half lifted and half dragged him over to a pile of blankets. "Feel any better?" asked Jimmy, as he gave his friend another drink from a canteen. "Yes, of a little betterness am I," was the answer. "But do not of mind me. I can get alongs. Look for a way out of these place if you can find him. Do not mind me."
