The chase of the Austrian submarine had been long and it was after nightfall when the D-16 again drew up in the shelter of the French fleet and Lord Hastings went aboard the flagship.

“Well, we got her,” were Lord Hastings’ first words to the French admiral.

“Good!” was the reply. “Tell me about it.”

Lord Hastings did so, and the admiral was loud in his praises of the D-16 and her crew.

Then Lord Hastings bethought himself of the blowing up of the French cruiser.

“Were all members of the crew saved?” he asked.

“All but ten,” was the reply. “They went down with the ship.”

“Poor fellows,” said Lord Hastings; “still it might have been worse.”

“Yes, it might have been worse,” replied the admiral, “and there might have been more sent to join them by the Austrian submarine had it not been for the gallant Lord Hastings and his crew.”

Lord Hastings waved aside this praise.

“Come, come,” he said, “we are too old in the service for such words. We do our duty as we see it, and that’s all there is about it. Now if it comes to praise, I can remember the time when you——”

“Enough!” cried the admiral, laughing. “As you say, we are too old in the service, you and I, for such words. Take the young fellows, now, and a word or two of praise, rightly spoken in the proper place, is an impetus to added bravery.”

“And ultimate death for their foolishness,” said Lord Hastings slowly.

“True; but what would you? Young blood, you know.”

“Well,” said Lord Hastings, “I must be going. I shall leave you in the morning.”

“Headed which way?” asked the admiral.

“For the Dardanelles, to join the allied fleet.”

“Mon Dieu! I envy you,” said the old admiral. “Here I sit with nothing to do while you have all the fun.”

“And what was it you said about young blood?” asked Lord Hastings with a laugh.

The admiral smiled.

“Oh, well,” he said. “We sailors never grow old.”

The two old friends shook hands affectionately, and Lord Hastings took his leave.

All was quiet on the submarine when he went on board, and he turned in at once. Not a man aboard the D-16 that night but slept a well-earned sleep, for the chase of the Austrian submarine, while not so long in itself, had, nevertheless, sapped the energy of all. The strain under which they worked—never knowing when a torpedo would send them all to their deaths—was tremendous.

All were up bright and early the following morning, however, and shortly after 7 o’clock the D-16 got under way. As she swung round and pointed her nose toward the Mediterranean there was a booming of guns from every ship of the French fleet and a cheer from the crews, for word of what the submarine had accomplished had spread rapidly, and officers and men alike joined in a parting ovation.

Through the Adriatic and into the Mediterranean went the British submarine D-16, speeding rapidly upon the surface of the water. Then she turned her head toward the east and Lord Hastings laid a course that, barring accidents, would quickly bring her to the entrance of the Dardanelles, where the allied fleet was still shelling the Turkish fortifications.

As they sped swiftly along, they talked of the war, of past adventures, of what lay in store for each in the future, and of many other things.

“And so Russia is to be given Constantinople,” said Frank.

“Why not?” asked Jack.

“Why, no reason,” replied Frank, “except that England has, heretofore, always opposed Russia’s obtaining an outlet into the Mediterranean.”

“War makes strange bedfellows,” said Lord Hastings sententiously.

“It does,” agreed Jack, “as is evidenced by the alliance of Germany and Turkey.”

“How about England and Japan?” asked Frank.

“Oh,” said Jack, “that’s different.”

“In what way?”

“Well, the Japanese are civilized. You can’t say so much for the Turk. Besides, England’s and Japan’s interests in the far east are so closely allied that an alliance is not to be wondered at.”

“Well, here is something I want to know,” said Frank. “If Japan were to go to war with the United States, what would England do? Help her?”

“Why, no,” said Jack. “Of course not.”

“But the alliance?”

“In that event,” said Lord Hastings slowly, “the alliance would be put aside. It is as though a man, who had formed an alliance with another, were asked to work against his own son or daughter. He wouldn’t do it, and America is a child of England, after all.”

“Well,” said Frank, “I have heard many theories advanced. I just wanted to know yours.”

No incident marred the peaceful progress of the D-16 as she made her way through the sunny waters of the Mediterranean. The weather was beautiful and Lord Hastings, Frank and Jack spent many pleasant hours upon the little bridge.

“How long before we shall reach the entrance to the Dardanelles?” asked Frank during one of these siestas.

“At the rate we are going,” was the reply, “we should be there tomorrow morning. Of course, we might even do better than that, but I am in no particular hurry. There will not be much action before daylight.”

“I suppose by this time,” said Frank, “that progress in reducing the Turkish fortifications is swifter than before.”

“It’s hard to say,” was the reply. “The outer forts are, of course, not so strong as the inner fortifications. As you know, having been there, the strait is very narrow, less than a mile in some places, and it is absolutely impossible for warships to force their way through without first destroying all guns on either side.”

“But you remember our prisoner told us the Queen Elizabeth was wreaking great havoc with these. What do you know of her, sir?”

“Not as much as I should. She is the newest of Great Britain’s dreadnoughts; and, without the shadow of a doubt, the most powerful sea-fighter afloat today. She carries the heaviest guns and outranges anything afloat. Shore batteries, powerful as they may be, are no match for her, for she can stand off at a distance of twenty miles and pound them with perfect safety to herself.”

“She must indeed be a terrible engine of destruction,” said Frank.

“She is,” replied Lord Hastings calmly, “and eventually, mark me, she, and ships of her class, will be the means of bringing the Germans to terms, land victories of the most gigantic scale notwithstanding.”

“Well, the sooner the better,” said Frank.

“I agree with you,” declared Jack.

“And I, too,” remarked Lord Hastings.

It was just after daylight on the following morning that Frank, who was on the bridge, made out in the distance huge clouds of smoke and heard the faint sounds of booming guns.

“They are at it again,” he told himself.

He went below and aroused Jack and Lord Hastings.

They were soon dressed and joined Frank on the bridge.

Every few seconds, above the sounds of the distant guns, one roared louder than the rest.

“The Queen Elizabeth,” Lord Hastings explained. “Her voice is one that already must have carried terror to the heart of Constantinople and her people.”

The speed of the submarine was increased, for Lord Hastings wished to arrive upon the scene as soon as possible. Gradually the forms of the huge ships of the allied fleet could be distinguished.

“Eighteen, nineteen, twenty,” counted Frank. “I thought there were more than that. Where are the others?”

“Those you see now,” said Lord Hastings, “have been left to guard the entrance to the strait. The others, the outer fortifications having been put out of commission, undoubtedly have progressed two or three miles into the strait.”

“More than that, sir,” said Jack. “You remember the prisoner told us they were reported to have progressed twelve miles.”

“True, I had forgotten. I am willing to predict, then, that they have progressed farther by this time.”

Lord Hastings’ prediction proved correct; for when the D-16 drew up under the shelter of one of the largest of the battleships, and Lord Hastings went aboard, he learned that the Queen Elizabeth, leading the fleet, had progressed all of twenty miles and her great guns were now busily engaged in hurling huge projectiles miles farther.

From the commander of the British vessel which he boarded, Lord Hastings learned some of the details of the fighting up to date. He learned how, when it had been decided to attempt a passage of the Dardanelles, the Queen Elizabeth, fearless and powerful, had taken the lead, and had made short work of the outer defenses.

Her terrible projectiles had wreaked havoc upon the fortifications, and, when she had all but dismantled one, she moved on to another, leaving the smaller vessels to complete the work of destruction. And so on along the strait for twenty miles.

Word had just been received that the Turks were massing huge land forces, with heavy artillery, along the banks of the Dardanelles to attempt to check the onward movement of the allied fleet. Several of these forces had already been put to rout by the powerful and accurate fire of the warships, but now, it was said, a greater and more powerfully armed force was advancing to give battle.

Other than the success attained in the Dardanelles itself, the attempted passage had done two other things of benefit to the British cause. First it had forced the Turks to give up their proposed invasion of Egypt, and, second, it had caused the abandonment of the attempt to capture the Suez canal from the British troops, although it is doubtful if either would have terminated successfully for the Turks.

Lord Hastings returned aboard the D-16 and explained the situation to the lads.

“And what shall we do now, sir?” asked Jack.

“Well,” said Lord Hastings slowly, “I see no use waiting outside and letting the other fellows do all the work. Guess we might as well go along after them.”

“Good!” cried both lads in a single voice.
