"Not a very cheerful prospect, sir," said Frank, quietly.

"I agree with you. However, they haven't caught us yet. We'll give them a hard race."

"Is the vessel armed, sir?"

"It should be, if I have been informed correctly. I'll have a look about. Hold to your course until I return."

He moved away. He was back in a few moments, however, with the announcement that there were four 12-pounders aft, as well as four forward.

"Enough to fight with," he announced gravely.

"But we haven't the men to man them, sir," protested Frank.

"We'll impress our prisoners into service if it's necessary. With a man to guard them they can handle the engine room."

"I am afraid it will come to that, sir," said Frank.

Von Ludwig shrugged.

"What will be, will be," he replied quietly.

And it did come to that, as Frank had predicted As the vessel still flew through the water at full speed, there came a sudden cry from the lookout forward:

"Cruiser off our port bow, sir!"

Von Ludwig sprang forward. He gazed at the vessel quickly and then called to Frank:

"Port your helm hard!"

Frank obeyed without question and the _Bismarck_ swung about sharply.

Von Ludwig sprang to his side.

"They'll pick us up with their searchlight in a minute or two," he cried. "Come with me, Templeton! Chadwick, hold that course till I come back."

Jack sprang after von Ludwig. The latter hurried to the cabin where the German prisoners were confined. He unloosened the bonds of five.

"You men," he said sharply, "will go before us to the engine room, where you will perform the necessary duties."

Under the muzzles of the weapons of Jack and von Ludwig, the men obeyed, for there seemed nothing else to do. In the engine room von Ludwig explained:

"I want you men to put forth your best efforts. Any foolishness and you will be shot, for I will take no chances. Harris, can you guard them?"

"Yes, sir," replied Harris, with a smile. "Give me another gun, sir."

Von Ludwig pa.s.sed a revolver to Harris.

"There must be no half way methods here," he said quietly. "Shoot the first man who makes a false move. Ask questions afterward. Our lives depend upon it."

"I shall obey your instructions, sir."

"Good!" Von Ludwig addressed the former engine-room crew. "Follow me, men," he exclaimed.

No questions were asked and the others followed Jack and von Ludwig from the room, leaving Harris in command of the German crew of five.

These Germans, under the muzzles of Harris' two revolvers, fell to work immediately.

Von Ludwig led the former engine-room crew to the guns forward.

"Man these guns," he said quietly. "There may be fighting to do. When I give the word fire as rapidly and as accurately as possible at the closest enemy vessel."

"Very well, sir," said one of the men.

Von Ludwig called to Jack to follow him and returned to the bridge.

There he gave a slight alteration in course to Frank and the vessel's head turned slightly.

"Funny they haven't raised us with that searchlight," von Ludwig muttered to himself.

The _Bismarck_ was dashing through the water at a rapid gait. Suddenly she became the center of a blinding glare. The searchlight of a German cruiser a half a mile to port had picked them up. Von Ludwig gave a sharp command to the men who manned the forward guns.

"Aim and fire!" he cried.

A moment later one of the guns spoke and a sh.e.l.l screamed across the water toward the German cruiser. Apparently it did not find its mark, however, for nothing happened aboard the enemy to indicate the shot had struck home.

"Again!" cried von Ludwig.

Another gun boomed. Followed a sharp explosion.

"Good work, men!" cried von Ludwig. "Try it again."

But the next shot came from the enemy. A sh.e.l.l screamed overhead.

"They'll do better with the next shot, sir," said Jack, quietly.

"So they will," was von Ludwig's quiet response. "Starboard your helm, Mr. Chadwick."

Frank obeyed immediately, and again the course of the _Bismarck_ was changed quickly; and none too soon.

For another salvo had come from the German cruiser and two sh.e.l.ls flew past the spot where the _Bismarck_ would have been at that moment had her course not suddenly been altered.

"Fire, men!" cried von Ludwig. "Fire as fast as you can. If you can't disable her we are done for!"

The men who manned the _Bismarck's_ guns were working like Trojans.

Once, twice, thrice more they fired; and upon the fourth shot there came a cry of dismay from aboard the enemy cruiser.

"Must have hit something, sir," said Frank.

"Right. I trust it was a vulnerable spot."

Twice more the German cruiser fired at the _Bismarck_, but without result. The smaller vessel was drawing ahead rapidly now.
