However, for two hours Ensign Adams's division kept closely on the heels of the quarry, now stopping to obtain a "fix," now running full speed to catch up with the fleeing prey. At one o'clock the plotting-room reported that the submerged boat was just about a hundred yards ahead.

The three chasers laid barrages according to pattern, and the three "Y"

guns shot their depth charges; the region of the "fix" was so generously sowed with these bombs that it seemed an impossibility that the German could have escaped.

As soon as the tumult quieted down, the chasers put out their tubes and listened. For twenty minutes not a sound issued from the scene of all this activity. Then a propeller was heard faintly turning or attempting to turn. The noise this time was not the kind which indicated an effort to steal away furtively; it conveyed rather the impression of difficulty and strain. There was a slight grating and squeaking such as might have been made by damaged machinery. This noise lasted for a few seconds and then ceased. Presently it started up again and then once more it stopped. The submarine was making a little progress, but fitfully; she would go a few yards and then pause. A slight wake now appeared upon the surface, such as a submerged U-boat usually left when the water was calm; the listeners at the tube were pleased to note that the location of this disturbance coincided precisely with their "fix," and thus, in a way, confirmed their calculations. One of the subchasers promptly ran ahead and began to drop depth charges on this wake. There was not the slightest doubt that the surface boat was now directly on top of the submarine. After one of the depth charges was dropped, a black cylindrical object, about thirty inches long, suddenly rose from the depths and jumped sixty feet into the air; just what this unexpected visitant was no one seems to know, but that it came from the hunted submarine was clear.

Under such distressing conditions the U-boat had only a single chance of saving itself; when the water was sufficiently shallow--not deeper than three hundred feet--it could safely sink to the bottom and "play dead,"

hoping that the chasers, with their accursed listening devices, would tire of the vigil and return to port. A submarine, if in very good condition, could remain silently on the bottom for two or three days.

The listeners on the chaser tubes presently heard sounds which suggested that their enemy was perhaps resorting to this manoeuvre. But there were other noises which indicated that possibly this sinking to the bottom was not voluntary. The listeners clearly heard a sc.r.a.ping and a straining as though the boat was making terrific attempts to rise. There was a lumbering noise, such as might be made by a heavy object trying to drag its hulk along the muddy bottom; this was followed by silence, showing that the wounded vessel could advance only a few yards. A terrible tragedy was clearly beginning down there in the slime of the ocean floor; a boat, with twenty-five or thirty human beings on board, was hopelessly caught, with nothing in sight except the most lingering death. The listeners on the chasers could follow events almost as clearly as though the inside of the U-boat could be seen; for every motion the vessel made, every effort that the crew put forth to rescue itself from this living h.e.l.l, was registered on the delicate wires which reached the ears of the men on the surface.

Suddenly sharp metallic sounds came up on the wires. They were clearly made by hammers beating on the steel body of the U-boat.

"They are trying to make repairs," the listeners reported.

If our subchasers had had any more depth charges, they would have promptly put these wretches out of their misery, but they had expended all their ammunition. Darkness was now closing in; our men saw that their vigil was to be a long one; they sent two chasers to Penzance, to get a new supply of bombs, and also sent a radio call for a destroyer.

The spot where the submarine had bottomed was marked by a buoy; lanterns were hung out on this buoy; and two units of chasers, six boats in all, prepared to stand guard. At any moment, of course, the struggling U-boat might come to the surface, and it was necessary to have forces near by to fight or to accept surrender. All night long the chasers stood by; now and then the listeners reported sc.r.a.ping and straining noises from below, but these grew fainter and fainter, seeming almost to register the despair which must be seizing the hearts of the imprisoned Germans.

At three o'clock in the morning a British destroyer arrived and presently the two chasers returned from Penzance with more ammunition.

Meanwhile, the weather had thickened, a fog had fallen, the lights on the buoy had gone out, and the buoy itself had been pulled under by the tide. The watching subchasers were tossed about by the weather, and lost the precise bearing of the sunken submarine. When daylight returned and the weather calmed down the chasers again put over their tubes and attempted to "fix" the U-boat. They listened for hours without hearing a sound; but about five o'clock in the afternoon a sharp piercing noise came ringing over the wires. It was a sound that made the listeners'

blood run cold.

Only one thing in the world could make a sound like that. It was the crack of a revolver. The first report had hardly stilled when another shot was heard; and then there were more in rapid succession. The listeners on two different chasers heard these pistol cracks and counted them; the reports which these two men independently made agreed in every detail. In all, twenty-five shots came from the bottom of the sea. As there were from twenty-five to thirty men in a submarine crew the meaning was all too evident. The larger part of officers and men, finding themselves shut tightly in their coffin of steel, had resorted to that escape which was not uncommonly availed of by German submarine crews in this hideous war. Nearly all of them had committed suicide.

Meanwhile, our subchaser detachment at Corfu was performing excellent service. In these southern waters Captain C. P. Nelson commanded two squadrons, comprising thirty-six vessels. Indeed, the American navy possessed few officers more energetic, more efficient, more lovable, or more personally engaging than Captain Nelson. The mere fact that he was known among his brother officers as "Juggy Nelson" gives some notion of the affection which his personality inspired. This nickname did not indicate, as might at first be suspected, that Captain Nelson possessed qualities which flew in the face of the prohibitory regulations of our navy: it was intended, I think, as a description of the physical man.

For Captain Nelson's rotund figure, jocund countenance, and always buoyant spirits were priceless a.s.sets to our naval forces at Corfu.

Living conditions there were not of the best; disease was rampant among the Serbians, Greeks, and Albanians who made up the civil population; there were few opportunities for entertainment or relaxation; it was, therefore, a happy chance that the commander was a man whose very presence radiated an atmosphere of geniality and enthusiasm. His conversational powers for many years had made him a man of mark; his story-telling abilities had long delighted naval officers and statesmen at Washington; no other selection for commander could have been made that would have met with more whole-hearted approval from the college boys and other high-type civilians who so largely made up our forces in these flotillas. At Corfu, indeed, Captain Nelson quickly became a popular favourite; his mind was always actively forming plans for the discomfiture of the German and Austrian submarines; and all our Allies were as much impressed with his energy as were our own men. For Captain Nelson was more than a humorist and entertainer: he was pre-eminently a sailor of the saltiest type, and he had a real barbaric joy in a fight.

Even in his official communications to his officers and men he invariably referred to the enemy as the "Hun"; the slogan on which he insisted as the guiding principle of his flotilla was "get the Hun before he has a chance to get us." He had the supreme gift of firing his subordinates with the same spirit that possessed himself; and the vigilance, the constant activity, and the courage of the subchasers'

crews admirably supplemented the sailor-like qualities of the man who commanded them.

I have already referred to the sea-going abilities of the subchasers; but the feat accomplished by those that made the trip to Corfu was the most admirable of all. These thirty-six boats, little more than motor launches in size, sailed from New London to Greece--a distance of 6,000 miles; and, a day or two after their arrival, they began work on the Otranto barrage. Of course they could not have made this trip without the a.s.sistance of vessels to supply them with gasolene, make the necessary routine repairs, care for the sick and those suffering from the inevitable minor accidents; and it is greatly to the credit of the naval officers who commanded the escorting vessels that they shepherded these flotillas across the ocean with practically no losses. On their way through the Straits of Gibraltar they made an attack on a submarine which so impressed Admiral Niblack that he immediately wired London headquarters for a squadron to be permanently based on that port.

As already said, the Otranto Strait was an ideal location for this type of anti-submarine craft. It was so narrow--about forty miles--that a force of moderate size could keep practically all of the critical zone under fairly close observation. Above all, the water was so deep--nearly 600 fathoms (3,600 feet)--that a submarine, once picked up by the listening devices, could not escape by the method which was so popular in places where the water was shallow--that of sinking to the bottom and resting there until the excitement was over. On the other hand, this great depth made it very difficult to obstruct the pa.s.sage by a fixed barrier--a difficulty that was being rapidly overcome by a certain Franco-Italian type of torpedo net. This barrage, after the arrival of our chasers, was so reorganized as to make the best use of their tactical and listening qualities. The several lines of patrolling vessels extended about thirty-five miles; there were vessels of several types, the whole making a formidable gauntlet, which the submarines had to run before they could get from the Adriatic to the Mediterranean.

First came a line of British destroyers; it was their main duty to act as protectors and to keep the barrage from being raided by German and Austrian surface ships--a function which they fulfilled splendidly. Next came a line of trawlers, then drifters, motor launches, and chasers, the whole being completed by a line of kite balloon sloops. Practically all these vessels, British as well as American, were provided with the American devices; and so well did these ingenious mechanisms function that it was practically impossible for any submarine to pa.s.s through the Otranto barrage in calm weather without being heard. In fact, it became the regular custom for the enemy to wait for stormy weather before attempting to slip through this dangerous area, and even under these conditions he had great difficulty in avoiding detection.

From July, 1918, until the day of the armistice, our flotilla at this point kept constantly at work; and the reports of our commanders show that their sound contacts with the enemy were very frequent. There were battles that unquestionably ended in the destruction of the submarines; just how much we had accomplished, however, we did not know until the Austrians surrendered and our officers, at Cattaro and other places, came into touch with officers of the Austrian navy. These men, who showed the most friendly disposition toward their American enemies, though they displayed the most bitter hostility toward their German allies, expressed their admiration for the work of our subchasers. These little boats, the Austrians now informed us, were responsible for a mutiny in the Austrian submarine force. Two weeks after their arrival it was impossible to compel an Austrian crew to take a vessel through the straits, and from that time until the ending of the war not a single Austrian submarine ventured upon such a voyage. All the submarines that essayed the experiment after this Austrian mutiny were German. And the German crews, the Austrian officers said, did not enjoy the experience any more than their own. There was practically no case in which a submarine crossed the barrage without being bombed in consequence; the _moral_ of the German crews steadily went to pieces, until, in the last month of the war, their officers were obliged to force them into the submarines at the point of a pistol. The records showed, the Austrian high officers said, that the Germans had lost six submarines on the Otranto barrage in the last three months of the war. These figures about correspond with the estimates which we had made; just how many of these the British sank and just how many are to be attributed to our own forces will probably never be known, but the fact that American devices were attached to all the Allied ships on this duty should be considered in properly distributing the credit.

We have evidence--conclusive even though somewhat ludicrous--that the American device on a British destroyer "got" one of these submarines.

One dark night this vessel, equipped with the C-tube, had pursued a submarine and bombed it with what seemed to have been satisfactory results. However, I have several times called attention to one of the most discouraging aspects of anti-submarine warfare: that only in exceptional circ.u.mstances did we know whether the submarine had been destroyed. This destroyer was now diligently searching the area of the battle, the listeners straining every nerve for traces of her foe. For a time everything was utterly silent; then, suddenly, the listener picked up a disturbance of an unusual kind. The noise rapidly became louder, but it was still something very different from any noise ever heard before. The C-tube consisted of a lead pipe--practically the same as a water pipe--which was dropped over the side of the ship fifteen or twenty feet into the sea; this pipe contained the wires which, at one end, were attached to the devices under the water, and which, at the other end, reached the listener's ears. In a few seconds this tube showed signs of lively agitation. It trembled violently and made a constantly increasing hullabaloo in the ears of the listener. Finally a huge German, dripping with water like a sea lion, appeared over the side of the destroyer and astounded our British Allies by throwing up his arms with "Kamerad!" This visitant from the depths was the only survivor of the submarine which it now appeared had indubitably been sunk. He had been blown through the conning tower, or had miraculously escaped in some other way--he did not himself know just what had taken place--and while floundering around in the water in the inky darkness had, by one of those providences which happen so frequently in war time, caught hold of this tube, and proceeded to pull himself up hand-over-hand until he reached the deck. Had it not been for his escape, the British would never have known that they had sunk the submarine!

This survivor, after shaking off the water, sat down and became very sociable. He did not seem particularly to dislike the British and Americans, but he was extremely bitter against the Italians and Austrians--the first for "deserting" the Germans, the latter for proving bad allies.

"How do you get on with the Italians?" he asked the British officer.

"Very well indeed," the latter replied, giving a very flattering account of the Italian allies.

"I guess the Italians are about as useful to you as the Austrians are to us," the German sea lion replied.

In writing to our officers about this episode, the British commander said:

"We have found a new use for your listening devices--salvaging drowning Huns."

On September 28, 1918, Captain Nelson received the following communication from the commander of the Allied naval forces at Brindisi, Commodore W. A. H. Kelly, R.N.:

"Can you hold twelve chasers ready to leave Corfu to-morrow (Sunday) for special service? They should have stores for four days. If unavoidable, barrage force may be reduced during their absence. Request reply.

Further definite orders will be sent Sunday afternoon."

To this Captain Nelson sent an answer which was entirely characteristic:

"Yes."

The Captain well knew what the enterprise was to which this message referred. The proposed undertaking was one which was very close to his heart and one which he had constantly urged. The Austrian port of Durazzo, on the Adriatic, at that time was playing an important part in the general conflict. It was a base by which Germany and Austria had sent supplies to their ally Bulgaria; and in September the Entente had started the campaign against Bulgaria which finally ended in the complete humiliation of that country. The destruction of Durazzo as a base would greatly a.s.sist this operation. Several ships lay in the harbour; there were many buildings used for army stores; the destruction of all these, as well as the docks and military works, would render the port useless. The bombardment of Durazzo was, therefore, the undertaking for which the a.s.sistance of our subchasers had been requested. It was estimated that about one hour's heavy sh.e.l.ling would render this port valueless as an Austrian base; and to accomplish this destruction the Italians had detailed three light cruisers, the _San Giorgio_, the _Pisa_, and the _San Marco_, and the British three light scout cruisers, the _Lowestoft_, the _Dartmouth_, and the _Weymouth_. According to the plan agreed upon the Italian ships would arrive at Durazzo at about ten o'clock on Wednesday morning, October 2nd, bombard the works for an hour, and then return to Brindisi; when they had finished, it was proposed that the British cruisers should take their places, bombard for an hour, and likewise retire. The duty which had been a.s.signed to the subchasers in this operation was an important one. The Austrians had a considerable force of submarines at Durazzo; and it was to be expected that they would send them to attack the bombarding warships. The chasers, therefore, were to accompany the cruisers, in order to fight any submarine which attempted to interfere with the game. "Remember the life of these cruisers depends upon your vigilance and activity," said Captain Nelson in the instructions issued to the officers who commanded the little vessels.

At nine o'clock that Sunday evening twelve chasers slipped through the net at Corfu and started across the Adriatic; they sailed "in column,"

or single file, Captain Nelson heading the procession in subchaser _No.

95_, his second in command, Lt.-Comdr. Paul H. Bastedo, coming next in chaser _No. 215_. The tiny fleet hardly suggested to the observer anything in the nature of military operations; they looked more like a group of motor launches out for a summer cruise. The next morning they arrived at Brindisi, the gathering place of all the Allied vessels which were to partic.i.p.ate in the operation--that same Brindisi (or Brundisium) which was one of the most famous ports of antiquity, the town from which Augustus and Antony, in 42 B.C., started on the expedition which, at the battle of Philippi, was to win them the mastery of the ancient world. Upon arriving Captain Nelson went ash.o.r.e for a council with Commodore Kelly, who commanded the British cruisers, and other Allied officers. When he returned Captain Nelson's face was glowing with happiness and expectation.

"It's going to be a real party, boys," he informed his subordinate officers.

Two days were spent at Brindisi, completing preparations; on Tuesday evening Captain Nelson called all his officers for a meeting on board the British destroyer _Badger_, to give them all the details of the forthcoming "party." If there had been any flagging spirits in that company when the speech began--which I do not believe--all depression had vanished when "Juggy" had finished his remarks; every officer left with his soul filled by the same joy of approaching battle as that which possessed his chief.

At 2.30 Wednesday morning the chasers left Brindisi, steering a straight course to Durazzo. The night was very dark; the harbour was black also with the smoke from the cruisers and other craft which were making preparations to get away. After steaming a few hours the officers obtained with their gla.s.ses their first glimpse of Durazzo; at this time there were no fighting ships in sight except the chasers, as the larger ships had not yet arrived. Captain Nelson knew that there were two or three Austrian destroyers at Durazzo, and his first efforts were devoted to attempts to persuade them to come out and give battle. With this idea in mind, the chasers engaged in what they called a "war dance" before the port; they began turning rapidly in a great circle, but all to no purpose, for the Austrian ships declined to accept the challenge. After a time the smoke of the Italian cruisers appeared above the horizon; this was the signal for the chasers to take their stations. Durazzo is located in an indentation of the coast; at the southern extremity of the little gulf the land juts out to a point, known as Cape Laghi; at the northern extremity the corresponding point is Cape Pali; the distance between these two points is about fifteen miles. Two subchaser units, six boats, were a.s.signed as a screen to the Italian cruisers while the bombardment was under way. One unit, three boats, was stationed at Cape Pali, to the north, to prevent any submarines leaving Durazzo from attacking the British cruisers, which were to approach the scene of activities from that quarter, and another unit, three boats, was stationed off Cape Laghi. Thus the two critical capes were covered against submarine surprises, and the attacking vessels themselves were effectively screened.

The Italian cruisers sailed back and forth for about an hour, blazing away at Durazzo, destroying shipping in the harbour, knocking down military buildings, and devastating the place on a liberal scale, all the time screened in this operation by our chasers. Meantime, unit B, commanded by Lieutenant-Commander Bastedo, had started for its station at Cape Pali. The Austrian sh.o.r.e batteries at once opened upon the tiny craft, the water in their neighbourhood being generously churned up by the falling sh.e.l.ls. Meanwhile, the British cruisers, after steaming for a while east, turned south in order to take up the bombarding station which, according to the arranged programme, the Italian warships were about to abandon. The three screening chasers were steaming in column, _No. 129_, commanded by Ensign Maclair Jacoby, U.S.N.R.F., bringing up the rear. Suddenly this little boat turned to the right and started scampering in the direction of some apparently very definite object. It moved so abruptly and hastily that it did not take the time even to signal to its a.s.sociates the cause of its unexpected manoeuvre.

On board _No. 215_ there was some question as to what should be done.

"Let's go," said Commander Bastedo. "Perhaps he's after a submarine."

_No. 215_ was immediately turned in the direction of the busy _No. 129_, when the interest of its officers was aroused by a little foamy fountain of spray moving in the water slightly forward of its port beam. There was no mystery as to the cause of that feathery disturbance. It was made by a periscope; it was moving with considerable speed also, entirely ignoring the subchasers, and shaping its course directly toward the advancing British cruisers. Commander Bastedo forgot all about subchaser _No. 129_, which apparently was after game of its own, and headed his own boat in the direction of this little column of spray. In a few seconds the periscope itself became visible; Commander Bastedo opened fire at it with his port gun; at the second shot a column of water and air arose about six feet--a splendid geyser which informed the pursuer that the periscope had been shattered. By this time the third chaser, _No. 128_, was rushing at full speed. The submarine now saw that all chance of attacking the British ships had gone, and turned to the south in an effort to get away with a whole skin. But the two subchasers, _215_ and _128_, quickly turned again and started for their prey; soon both were dropping depth charges and shooting their "Y" guns; and a huge circle of the sea was a ma.s.s of explosions, whirling water, mighty eruptions of foam, mist, and debris--and in the ma.s.s, steel plates and other wreckage flew from the depths into the air.

"That got him!" cried the executive officer from the deck of _No. 215_, while the crew lifted up its voices in a shout that was reminiscent of a college yell.

It was not until this moment that Commander Bastedo and his a.s.sociates remembered the _129_, which, when last observed, was speeding through the water on an independent course of her own. In the midst of the excitement there came a message from this boat:

"Submarine sighted!"

Then a second afterward came another message.

"My engines are disabled."

In a short time Bastedo had reached the boat.

"Where is the submarine?"
