Dave Darrin After The Mine Layers Part 26

"You couldn't keep me ash.o.r.e any longer," Darrin declared.

"Good enough!" said the executive officer, heartily. "We need you, sir!

We've been doing our best, but the enemy has been gaining on us. Last night two ships struck mines and went down before rescue could reach them. The Germans are beating us at this mine game, and something must be done, which, of course, sir, is another way of saying that a way must be found to do the right and necessary thing."

"I've been thinking that over for twenty-four hours," Darrin went on. "As soon as we are aboard I want to talk the whole situation over with you.

Will Dalzell be in today?"

"In about an hour, sir, I think. He needs fuel and some food supplies."

"Then we'll hold a council of war in the chart-room," Dave decided, as he b.u.t.toned up his coat. "I'm ready, Fernald."

Dave had already thanked the hospital authorities, and taken leave of them, so the two young naval officers pa.s.sed outside, made their way down to the water front, and soon thereafter stepped aboard the "Grigsby,"

reporting their arrival on board to the watch officer. Dave also saw that the forward gun damaged in the fight with the German destroyers had been replaced by a new one. From the gangway they went direct to the chart-room.

"I'll hear the reports on the work now, Fernald," Dave announced.

Two of the papers that came under Dave's hand especially interested him.

One was a detailed list of the ships that had struck mines during the last week in the waters in which he and Dalzell had been operating. The other doc.u.ment contained a report on the discovery and sinking of one fighting submarine and one submarine mine-layer.

From these reports Dave turned to the charts of the local waters. When Fernald came back with Dan Dalzell, Dave was still poring over the charts.

"From the rapid way in which German mines are being planted in these waters," Dave told his brother officers, "I am satisfied that the enemy submarines do not usually go all the way back to the base port. I believe that the mine-layers are often met by other craft that supply them with mines, and that the submarine mine-layers return quickly to the job of planting mines. Now, the sea area in which the mines are planted leads me to feel certain that the mine-layers rest frequently on these three shoals."

Dave pointed on the chart to the shoals in question.

"How many mine-sweeping craft have we now under our orders?" he inquired.

"Nine," said Dan, promptly.

"How many of them can we spare from mine-sweeping?"

"None," Dalzell replied, positively.

"Either we must spare some, or we must have some sweeper craft added to our fleet," Dave went on. "There are three of these shoals, and hereafter I want two mine-sweepers to spend their time dragging their wires over each shoal. That will take six craft, and these will not have time to do any sweeping in the open sea. We cannot clean up the mines themselves with three craft, can we?"

"Plainly not," Dan agreed, "since, with all nine, we have not been able to find and take up all the mines we should have located."

"Then we shall have to have more craft," Dave nodded. "Yet if we cannot have more craft a.s.signed to this work, we must go ahead with what we have and do more work. But I believe that the hunt over the shoals should be kept up day and night, without rest, for I am satisfied that the enemy mine-layers rest on these shoals more frequently than we have supposed."

After some further conversation Dave had his launch cleared away and went over to a British battleship for a conference with the British admiral in command in those waters. The best the admiral could do was to supply him with three of the hundred-and-ten-foot patrol boats. These, however, were provided with sweepers and possessed good speed.

"I hope you're right, Mr. Darrin," said the admiral, at the close of the interview. "To be frank with you, your predecessor in the work of cleaning up enemy mines in this area was a British naval officer, considerably older than yourself. He is a very capable man in many ways, but we felt that he had been so long on coast work that he was growing much too stale. So, when I decided to transfer him to other duties I thought of trying one of your American officers, a young man, full of spirit, and fresh for this work. So I asked your admiral for some one, and he sent Dalzell and yourself."

"So far," said Dave, "I have not done any better than my English predecessor, sir?"

"Frankly you have not, yet we must remember to deduct your very necessary week in hospital. However, you have done some other excellent things. The capture of the mine-laying neutral, the 'Olga,' for instance, was a splendid bit of work. The fight that you and Mr. Dalzell had with the three enemy destroyers was a fine job. But the mines in these waters continue to be as much of a menace as before."

"They won't be, by this time next week, sir. I promise that," said Dave, rising. "How soon can the commanders of the three patrol boats report to me?"

"At once. All three are here in the harbor, and, I am told, they are ready to put to sea."

"Then, sir, I propose, within a week, to hand you a wholly satisfactory report," Darrin went on. "I had to put in some time on the ground, and it was necessary to study a new problem. Then came a series of adventures that took me out of the work for a while. But now, sir, I hope to show you something new--results!"

CHAPTER XV

DARRIN SUSPECTS THE GERMAN PLAN

THE three shoals selected by Darrin extended over a length of about thirty miles along the coast. It was the center one of these shoals on which he had had previous experience.

Further, it was arranged that Dalzell should, in general, cruise along the lower fifteen miles of this stretch, while the "Grigsby" should cover the upper half. From time to time the two destroyers would meet.

After sending three mine-sweepers and the three patrol boats to the shoals, two craft to each shoal, Darrin saw to it that the other six were a.s.signed to duty in the deeper waters off sh.o.r.e.

Then, with a hearty signal to the "Reed," the "Grigsby" started northward. She steamed by the southernmost shoal, and was pa.s.sing the second when Darrin was called to the bridge by Ensign Ormsby.

"That patrol boat in there signals that she has made a find, sir, so I have changed the course and am heading in."

Dave's eyes gleamed as he made out the next signal from the patrol, which was:

"Soundings show her to be a big craft. Shall we rig the small bombs on the sweep wires?"

"Wait until we arrive," was the answering signal from the "Grigsby."

In a few minutes the destroyer was within hailing distance of the patrol boat, which was lying to in the neighborhood of the find.

"The enemy submarine appears to be at least 275 feet long, sir," reported the patrol boat commander.

"Then a depth bomb should do the business better," Dave shouted back through the megaphone. "Sail over the craft with your sweep, and I'll follow. Signal when you judge us to be squarely over her."

Under bare headway the "Grigsby" fell in behind the now slow-moving patrol boat. Almost at once the wire sweeps discovered the hull of the hiding monster.

Ahead steamed the patrol boat, the destroyer following. Aft two men stood by the depth bomb apparatus. Down came the white flag of the British signalman on the smaller craft.

Dave's hand rested on the telegraph lever to the engine-room. He signalled for full speed ahead, then at the proper moment he shouted:

"Let her go!"

An instant later the bomb splashed into the water.

Immediately following the splash there came a sullen, rending roar under water. A great column of water leaped up from the sea, a heavy volume of it landing on the after deck of the destroyer, all but washing overboard one of the lookouts. The pressure of water fairly lifted the stern of the "Grigsby" until her bow dipped far in.

Ensign Ormsby was thrown flat, almost rolling from the bridge. Dave, fortunately, had taken a grip that saved him from falling.

It seemed as though the destroyer herself had been blown up, but she quickly settled and scooted ahead at a furious rate.
