CHAPTER XX

DARRIN TURNS THE TABLES

BOTH commanding officers were asleep when the "Grigsby" and the "Reed"

pa.s.sed each other that morning, the "Grigsby" proceeding on to her station.

Dave would have gone back on the same water route he had hunted over the day before, but the dirigible, which had reached England safely, had not yet been put in shape for further service, and there was at present no other dirigible that could be spared for his service.

Therefore it was a matter of back to the shoals for temporary duty, yet of a kind that was very important.

At ten o'clock he was called, as that was the hour he had named for relieving Lieutenant Fernald.

The executive officer had come into the chart-room to call him, and remained while Darrin performed his hasty toilet.

"What's the weather?" Darrin asked.

"Misty, sir," replied the executive officer. "There's a fine drizzle, mixed with some fog. For the last half hour it has been impossible to see more than six hundred yards. That is why we are running at half speed. We're close to the middle shoal and I was afraid we'd run down one of our own mine-sweepers."

"The kind of weather every ship's master dreads," Dave remarked.

"Yes, sir, and the weather bites you through to the marrow. The temperature isn't very low, but I think you'll find yourself more comfortable if you dress warmly. I found it so cold as to be necessary to wear the sheepskin under my heaviest rain-coat."

In finishing his dressing Darrin bore this suggestion in mind. In a few minutes he stepped out on deck. The weather proved to be as unpleasant as Fernald had a.s.serted, and Dave was glad that he was warmly clad, for the wind, though not strong, was piercing.

"Sighted any mine-sweeper on the shoal?" Dave asked of Ensign Ormsby, the watch officer, as soon as he reached the deck.

"Only on the first shoal, which is in the 'Reed's' station, sir," Mr.

Ormsby replied. "Those belonging to our station must be farther north.

And we've sighted none out in deeper water. We couldn't in this thick weather, anyway."

"The view is so limited that this doesn't look like a promising day for us," Dave mused aloud, as he gazed around at as much of the water as he could see.

"It really doesn't, sir."

"Better reduce to one-quarter speed. The less speed the less chance there will be of the enemy hearing us."

Accordingly the "Grigsby" rolled along slowly, the splash and ripple of the water along her sides being a soothing accompaniment.

For an hour they proceeded thus, without sighting a ship. They had pa.s.sed the middle shoal, and were somewhat north of it when the two officers on the bridge observed that the sun was struggling feebly through the clouds and mist. A minute later, as if by magic, it burst out brightly, and the mist began to fade away.

"By Jove, sir, look at that!" almost whispered Ensign Ormsby.

Some seven hundred yards away from them, motionless on the water, her deck fully exposed, lay a submarine.

Neither deck gun was above decks. At least a dozen of the crew stood near the conning tower, and, of all things in the world, fishing.

"Quick work, there!" Dave called through the bridge telephone to the gunners forward. "Let number one gun send a sh.e.l.l over the craft. Don't hit her at the first shot. We'll capture that fellow, if possible!"

So quickly did the shot come that it was the first intimation the German seamen had of enemy presence.

From aloft the signal broke out:

"Don't try to fire a shot, or to turn, or we'll sink you!"

An officer's head popped up through the manhole of the conning tower, then almost as quickly was withdrawn.

As the "Grigsby," obeying her engines, leaped forward, the men behind both forward guns stood ready to fire at the word.

For the submarine crew to bring either gun into place would be the signal for the destroyer to open fire at a range constantly decreasing. Nor could the enemy craft employ her torpedo tubes without turning, which would have been instant signal for Darrin to order his gunners to fire on the submarine.

Through the manhole of the enemy craft leaped a signalman, flags in hand.

Using the international code he wigwagged rapidly this message:

"We will make a grace of necessity and surrender."

"That doesn't necessarily mean that they do surrender," Dave 'phoned to the officer in charge of the forward gun division. "If the enemy makes a move to bring a gun into view, or to swing so that a torpedo tube could be used, fire without order and fire to sink!"

The German commander evidently understood that this would be the course of the Yankees, for as the "Grigsby" bore down upon the submarine not a threatening move was visible.

Instead, the Hun crew, unarmed so far as the watchers on the destroyer could see, emerged from the conning tower and moved well up forward.

"Prepare to lower two boats," Dave called, and added instructions for a large crew for each launch. As the "Grigsby" came about and lay to, the launches were lowered. In the bow of each small craft was mounted a machine gun ready for instant action. The double prize crew was permitted to board the submarine without sign of opposition. At the command, German seamen began to file past two petty officers, submitting to search for hidden weapons, then pa.s.sing on into the launches alongside.

Last of all four officers came through the manhole, preparatory to enduring the same search. When all the prisoners had been taken aboard, the launches started back to the "Grigsby."

Dave Darrin caught sight of the officers, as the launches approached the destroyer, and felt like rubbing his eyes.

"The ober-lieutenant and von Sch.e.l.ling!" he exclaimed with a start. "They haven't recognized me yet. When they do that ober-lieutenant is going to wish that he had voted for going to the bottom of the sea!"

Not, indeed, until the officers came up over the side of the "Grigsby,"

and found Dave Darrin waiting on the deck, did the quartette of officers discover who their captor was.

"_You?_" gasped the ober-lieutenant! "Impossible!"

"Yes; you didn't expect to see me again, did you?"

"I--I--I thought you were----"

The German checked himself.

"You thought you had sent me to the bottom of the sea," Dave went on. "It wasn't your fault that you didn't, but you missed your guess."

Dave then gave the order for housing the prisoners below.

"Are you sending the officers to the same place of detention that you are sending my men?" demanded the ober-lieutenant, a spark of a.s.sertiveness in his manner.

"Unfortunately, I am obliged to do so," Dave answered. "I am aware that German officers consider themselves to be of a brand of clay much superior to that used in making their men."
