"Good! Then there is no need to delay. Let us go."

Hal and Chester followed the Germans from the tent.

Straight to the airplane in which Hal had piloted the Germans to their own lines from Hirson the Germans led the way. Beside the machine, they came to a stop.

"This trip," said the spokesman to Hal, "you shall carry a more distinguished personage."

"Very well, sir," said Hal with a slight bow. "Who, sir?"

"Chancellor Ebert," was the reply. "However, it is not desired that his departure be known; besides which, he will go incognito, his identity to be revealed only to Marshal Foch, and to be kept secret after that."

"I see," said Hal. "I shall never mention the matter, sir."

"I was sure I could depend on you. And your brother officer?"

"I can answer for him, too, sir."

"It is well. Then we may as well move."
