"Impossible!" he exclaimed. "There is no United States Army in France."
Despite himself, the American officer could hardly suppress a smile.
"Just listen to him!" exclaimed Frank, who was within hearing distance.
"Didn't I tell you the Germans would believe anything their generals told them?" replied Bart.
"My, but this is rich!" chortled Tom.
"I wouldn't have believed it if I hadn't heard it," chuckled Billy, in a tone too subdued for the lieutenant to notice.
"I assure you," said the lieutenant, "that there is an army of the United States in France, despite your unbelief. Why should it seem so strange?"
"But you couldn't possibly have gotten over here," persisted the prisoner.
"Why not?" asked the American.
"Because our U-boats would have stopped you," was the reply.
