"Hardly," returned von Ludwig; "but I have discovered that there is a high-powered motor boat aboard. We can launch that and move off."
"And as soon as the Germans break out here, they'll come after us and shoot us full of holes," said Harris.
"Well, that's true enough, too," agreed von Ludwig. "Of course, if we had an hour's start we might get through. But the door won't hold that long."
Harris had been turning a plan over in his mind.
"If you please, sir," he said slowly at last, "I have a plan that may work."
"Let's hear it," said Frank.
"Yes; let's have it," said von Ludwig.
"Well," said Harris, "one man, with a couple of revolvers, should be able to guard this passageway for an hour without trouble. He can shoot the Germans down as fast as they come up. My plan is this. Let one man stay behind on guard. The others can put off in the motor boat."
"But the one man will die," said Frank.
"Of course," said Harris, simply. "That shall be my job."
