To one thing they had made up their minds. There would be no going back to their old hiding place. That meant either starvation or surrender. Besides, if they turned back on being discovered, the Germans would know that they were hiding somewhere in the ruined town and they would not leave one stone on another until they found them. But if they made a break for the open country they would have their chance of escaping in the darkness. On they went like so many spectres, until, on reaching a shattered doorway, they crept close together for a whispered parley.
"So far so good," murmured Frank.
"Luck's been with us," agreed Bert.
"We can stand a whole lot of luck in this business," whispered Tom.
"It's a long, long way yet to our own lines," said Billy. "We haven't got more than a couple of blocks away from our old hangout, and there's no telling how much further it is before we strike the open country."
Just then a stone toppled from a wall and fell with a crash only a few feet away. In their tense state of alertness the unexpected sound made them jump.
"Just as well we weren't under that," remarked Frank, with a sigh of relief.
"Let's hope it won't bring some German sentry along to see what's making the racket," responded Bart.
"Just what it is doing," whispered Tom, as he heard a step approaching.
"Quick, fellows, get further back and lie down flat."
They almost ceased to breathe as a dim form passed by so close that they could almost have reached out and touched him. But the dust still rising from the shattered stone convinced the visitor that nature and not man was responsible for the disturbance, and, with a grunt of satisfaction that it was nothing worse, the sentry returned to his former post.
