“True,” said the general, when this was conveyed to him by Beth.  “Nevertheless, he is a prisoner of war, and must not be allowed to escape to his own people.”

Beth answered the Frenchman herself, looking him straight in the face.

“That strikes me as unfair, sir,” said she.  “The German must henceforth be a noncombatant.  He has been unable, since he was wounded and brought here, to learn any of your military secrets and at the best he will lie a helpless invalid for weeks to come.  Therefore, instead of making him a prisoner, it would be more humane to permit him to return to his home and family in Germany.”

The general smiled indulgently.

“It might be more humane, mademoiselle, but unfortunately it is against the military code.  Did I understand that your captain will guarantee the German’s safety?”

“Of course,” said Carg.  “If he escapes, I will surrender myself in his place.”

“Ah; but we moderns cannot accept Pythias if Damon runs away,” laughed the general.  “But, there; it will be simpler to send a parole for him to sign, when he may be left in your charge until he is sufficiently recovered to bear the confinement of a prison.  Is that satisfactory?”

“Certainly, sir,” replied the captain.

Elbl had remained silent during this conversation, appearing not to understand the French and English spoken.  Indeed, since his arrival he had only spoken the German language, and that mostly in his intercourse with Carg.  But after the French officer had gone away Beth began to reflect upon this reticence.

“Isn’t it queer,” she remarked to Uncle John, “that an educated German—­one who has been through college, as Captain Carg says Elbl has—­should be unable to understand either French or English?  I have always been told the German colleges are very thorough and you know that while at Ostend we found nearly all the German officers spoke good English.”

“It is rather strange, come to think of it,” answered Uncle John.  “I believe the study of languages is a part of the German military education.  But I regret that the French are determined to keep the poor fellow a prisoner.  Such a precaution is absurd, to my mind.”

“I think I can understand the French position,” said the girl, reflectively.  “These Germans are very obstinate, and much as I admire Lieutenant Elbl I feel sure that were he able he would fight the French again to-morrow.  After his recovery he might even get one of those mechanical feet and be back on the firing line.”

“He’s a Uhlan.”

“Then he could ride a horse.  I believe, Uncle, the French are justified in retaining him as a prisoner until the war is over.”

Meantime, in the captain’s room the two men were quietly conversing.

“He wants you to sign a parole,” said Carg.

“Not I.”

“You may as well.  I’m responsible for your safety.”
