"All right, sir. And you?"

"Everything shipshape. Now for the crew. First, however," he said, addressing Jack and Frank, "don the clothing of these two officers. You shall be my second and third in command."

The lads returned to the cabin they had just quitted and stripped the prisoner. Jack donned the uniform, for the German was a big man. Then they hurried into the second cabin and performed a similar operation and Frank soon was attired in the uniform of a German lieutenant.

"Now," said von Ludwig, "have the crew report here and keep your guns ready."

Frank made his way aft, and in German, called:

"All hands forward!"

The crew came tumbling from their bunks and hurried forward, most of the men no more than half dressed. Jack, Frank and Harris, on either side of von Ludwig, confronted them.

"Men," said von Ludwig, "I am the new commander of this ship and we shall get under way immediately. Fearing that you will not always obey my commands, I have brought along these little persuaders."

A pair of automatics flashed in his hands and covered the ten sailors.

"Hands up!" he cried.
