A German voice broke in.

“You can have but ten minutes,” it said. “After that you must take your chances.”

“Fair enough, Fritz,” called an American. “Hey! You in the shell hole, come on in here.”

“It’s safer here,” was the reply.

Again a German voice interrupted.

“If the Yank is afraid,” it said, “we will allow two of your number to go and get him.”

Half a dozen men would have leaped from the trench had Hal not stayed them.

“You stay here and cover us,” he said. “Lieutenant Crawford and I will go. At the first sign of treachery, fire without hesitation.”

“Very well, sir,” said Private McHugh.

Hal and Chester leaped down and advanced into the darkness of No Man’s Land.
