There was no firing in this particular sector of the battlefield for the moment, but to the north and south Hal and Chester could hear the rumble of the big guns as the artillery duel continued on each flank.

“Where are you going to take us, lieutenant?”

“None of your business,” was their captor’s response.

“You’re not a very civil sort of a fellow, are you?” demanded Hal.

“Hold your tongue, if you know what’s good for you,” was the response. “We don’t have time to bother with a pair of American pigs. You’ll be lucky if you are not ordered shot at once.”

“Oh, I guess they won’t shoot us,” said Hal quietly. “We’re prisoners of war, you know.”

“Well, you wouldn’t be the first to be shot offhand,” said the German lieutenant.

“I’ve heard that you’re a rather barbarous lot,” returned Hal, “but I didn’t know you were as bad as that.”

The German stepped close to Hal and shook his fist in the lad’s face.

“That’s enough out of you,” he cried angrily.
