“All right, you can let him go now, sir,” the marine said.

Hal released his hold and stepped back, at the same time covering the German with the Luger.

“Sit down,” said Bowers.

It is doubtful if the young German understood Bowers’ words, but he certainly caught their import, for he sat down in front of the tank.

Bowers turned to Hal.

“You see, they’re all alike, sir,” he said. “They’re not to be trusted.”

“So I see.” said Hal. “Well, I won’t be caught napping again. And this is the second one that has tried that ‘Kamerad’ trick on us in the same day.”

“Almost within the same hour, you might say,” replied Bowers. “But what are we going to do with him?”

“That’s a hard question,” was Hal’s reply. “We can’t make him prisoner and I’m not disposed to let him go scott-free in view of his actions. Guess we might as well tie him up and leave him here.”

“Suits me, sir.”
