Naturally, after what had happened and bearing in mind the strange sight Roger and Jimmy had witnessed, there was but one thought in the minds of at least four of the Khaki Boys--Iggy was temporarily out of it. And this thought was that some disaster had overtaken the American forces above ground while much was happening to them below ground, in the dugout and tunnel. Perhaps the Germans had made a counter-attack, retaken the trenches from which they had been driven, and were now about to swarm down into the dugout, where the Khaki Boys were, to capture them. "Don't give up!" cried Jimmy fiercely. "Stand 'em off as long as you can, and then----" Once more he was interrupted by a voice coming from the passage leading from the dugout. "Lively now!" was the command. "There's a bare chance we may get 'em out this way, but we've got to hurry!" "You won't get us out alive!" said Bob fiercely, and he looked around the dugout for some way of escape. There were only two entrances--or exits--whichever one might choose to call them--the one by which the boys had emerged from the tunnel, and the other by which they hoped to leave. But this last was now blocked by an approaching party. "Stand together, boys!" said Sergeant Jimmy in a low voice. "Shall I douse the glim?" asked Franz. He was about to blow out the candle when into the dugout came hurrying a squad of khaki-clad soldiers, and it needed but a glance from the Khaki Boys to show them that they were their own comrades of the 509th Infantry. Lieutenant Morrison was in charge--an officer of whom the five Brothers were very fond. "Here they are!" cried the lieutenant. "How in the world did you boys escape? We saw the place where the big German shell struck, and we didn't think there'd be more than half of you left alive after the dugout caved in, as it must have done. Yet here you all are." "One's missing, sir," said a corporal. "There were five and----" "Here I iss!" exclaimed Iggy. "Part of me is alife, anyhow!" There was a laugh at this--a laugh that told of overstrained nerves being mercifully relieved. "Is he badly hurt?" asked Lieutenant Morrison, as he looked at the Polish lad, his friendly guard moving away from in front of him. "Something fell on one foot when the dugout gave way under pressure from the Hun shell," explained Roger. "I hope it isn't bad." "Well, we'll get him to a dressing station as soon as possible," went on the young officer. "There's been a merry ruction up above, as I suppose you boys have guessed. As soon as I got things a bit straightened out, some one told me about a party being on leave down in the old German dugout, and I at once organized a rescue squad. How did you manage to escape?" Jimmy and his chums related their experience, and, in turn, Jimmy asked: "Have the Huns put one over on us?"
