The Submarine Hunters by Percy F. Westerman (books for students to read txt) 📕

The only response from the chase was the hoisting of the red ensign, for previously she had shown no colours. Slowly, defiantly, the bunting was hauled close up, and ironically "dipped" three times.

Again and again the submarine's bow-chaser fired. The shells were well aimed as regards direction, but all fell short. Imperceptibly the merchantman had increased distance.

"Look at the fools!" Ross heard the Kapitan remark, as he kept his binoculars focused on his intended prey. "They are trying to snapshot us. Are all Englishmen so blind to peril?"

"Are you sure they haven't a couple of quick-firers mounted aft, sir?" asked the Unter-leutnant. "There are several men gathered round something on the poop."

"Himmel, I hope not!" ejaculated Schwalbe. "But no; had they any guns they would have opened fire before now. What is the matter with our gun-layer? It is about time he got a shell home."

The Unter-leutnant lowered himself on the foredeck, and shouted angrily at the seaman whose duty it was to "lay" the bow-chasers. The man again bent over the sights.

This time the shell pitched ahead of the chase, but slightly to port. Some of the spray thrown up by the projectile fell on board.

"Is that the best you can do, you brainless idiot?" shouted Schwalbe wrathfully. Now that he was in pursuit he was loath to be baffled, but at the same time he realized that the submarine was using a lot of precious fuel and a prodigious amount of ammunition without any definite result.

In the midst of his torrent of abuse directed upon the luckless gun-layer, Kapitan Schwalbe suddenly stopped. Gripping the rim of the oval hatchway he gazed, horror-stricken, at two objects bobbing in the water directly in the path of the submarine. Then, recovering his voice, he shouted to the quartermaster to port helm.

The fellow obeyed promptly, but it was too late. Practically simultaneously, two barrels swung round and crashed alongside the submarine's hull.

Officers and men, expecting momentarily to find themselves blown into the air, stood stock-still. Then, as nothing so disastrous occurred, Schwalbe gave orders for easy astern.

The barrels, connected by a span of grass rope, had been thrown overboard from the pursued vessel, in the hope that the submarine would foul her propellers in the tangle of line. Once a blade picked up that trailing rope, the latter would coil round the boss as tightly as a band of flexible steel.

The plan all but succeeded; only the metal guards protecting the propellers saved them from being hopelessly jammed. Yet the attempt was attended with good results as far as the British ship was concerned, for by the time U75 had lost way and had cautiously backed away from the obstruction, the swift cargo-vessel had gained a distance that put her beyond all chance of being overhauled.

Infuriated by his failure, Kapitan Schwalbe went aft and descended into his cabin. He was hardly conscious of the presence of his two involuntary guests as he passed. He was thinking of the fate that had consigned him to a perilous and uncongenial task. Without doubt the vessel he had been pursuing was equipped with wireless, and by this time a number of those dreaded hornets would be tearing towards the spot. To add to his discomfiture it was reported to him that the reserve of fuel on board had seriously dwindled. In order to remain effective it was necessary that U75 should replenish her tanks before another forty-eight hours had passed.

According to his customary tactics, Schwalbe ordered the submarine to dive to sixty feet. At that depth she would be safe from any possibility of being rammed. Provided she could avoid the under-water obstructions with which the British naval authorities had sown the bed of the sea at almost every point likely to be frequented by lurking hostile submarines, she was in no actual danger.

Gaining his diminutive cabin, Schwalbe by sheer force of habit consulted the aneroid. The mercury was falling rapidly. Since he last looked, barely two hours previously, it had dropped 764 to 734 millimetres, or an inch and two-tenths. That meant that the anti-cyclone was rapidly breaking up, and that a severe gale was approaching with considerable swiftness.

U75 must submerge and seek shelter. It was impossible for her to keep at a uniform depth unless she maintained steerage-way; that meant a great demand upon her storage batteries. She could not remain on the bottom of the sea in a heavy gale, owing to the constant "pumping" or up-and-down movements caused by the varying pressure of passing waves, unless she sought a sheltered roadstead—and sheltered roadsteads were generally mined, or guarded by some ingenious device that had already accounted for several of U75's consorts.

Producing a chart of the Bristol Channel, Schwalbe unfolded and spread it upon a table. Then, in conjunction with a translation of the latest British Admiralty guide to the west coast of England, he proceeded to select what he hoped would be a snug shelter during the coming storm.

"Herr Rix!" he shouted. "I'll make for this anchorage. There's every indication of a strong blow from the nor'-east."

"This" was Helwick Channel, a deep, almost blind passage between the Glamorgan coast and an outlying submerged reef known as the East and West Helwick. In fine weather it was a short cut for traders plying between Llanelly and Swansea. In bad weather it was a place to be avoided, as far as sailing vessels were concerned. Sheltered by the bold outlines of Worm's Head, it ought to prove an ideal lurking-place until the gale had blown itself out, for there was little danger of the place being used as an anchorage, since vessels preferred to give the rock-bound coast a wide berth. On this account, it was also highly probable that the Helwick channel had not been safe-guarded by the British naval authorities.

Just before sunset, U75, having made the passage unobserved, brought up in twelve fathoms of water, resting evenly on the firm, hard sands at the bottom.

Ross and his chum turned in early. There was nothing for them to do. They held aloof from the crew; there were no books to entertain them, no games to amuse them. The submarine was now motionless, sufficient water ballast having been taken in to allow her to settle firmly upon the bottom; but, in order to be prepared, the anchor was let go. Thus not the slightest movement of the hull was apparent. The rest, after hours of erratic movement on the oily swell, was a welcome one.

The lads had set their joint watch by the submarine's time, which, being mid-European standard, was one hour fast of Greenwich.

For several hours they slept soundly and undisturbed. Suddenly they were both awakened by the muffled tramp of men in heavy sea-boots. The solitary light in the alley-way was switched off; the water-tight doors were firmly closed. Already the air in the confined space was stifling.

"What has happened?" asked Vernon anxiously, for the vessel, instead of resting immovably upon the bed of the channel, was now rolling sluggishly. Yet she could not be under way, for the motors were silent.

Springing from his bunk, Ross felt for the switch of the electric light. It was already down, yet the flow of current was interrupted.

"Let's find out," he said. "Come along."

The lads, before turning in, had carefully laid out their clothes, so as to be ready to slip into them at a moment's notice, yet it was a matter of considerable difficulty to dress in the dark.

"The door's closed," announced Ross as the lads groped their way to the end of the alley-way.

"I believe the submarine's holed," suggested Haye.

"No; she wouldn't lift as she's doing. Besides, the crew are moving about. Let's bang on the door with our boots."

For several minutes they hammered, but without result. The air, never very fresh, was now almost unbearable, owing to lack of ventilation. The imprisoned youths began to get desperate.

Then, without warning, the door slid back. The alley-way was flooded with brilliant light.

"Make haste!" shouted a voice which the lads recognized as that of Hans Koppe. At the same time he grasped Ross by the shoulder and literally dragged him across the steel threshold. Vernon followed quickly, but barely had he gained the compartment beyond than the massive steel door shot back again.

"Didn't you hear the order all hands for'ard?" asked Hans, not unkindly, for the white faces of the English lads told their own tale.

"No," replied Ross. "Besides, we are not included in the 'hands', are we?"

"You'll have to bear the consequences if you don't obey," rejoined Koppe. "I'm supposed to be looking after you, but how was I to know you hadn't turned out? Fortunately for you, I heard your knocking, and asked Herr Kapitan to open the doors. He was angry, but did so."

"What has happened then?" asked Trefusis, for the seaman seemed in a communicative mood.

"A shift of wind. It's blowing great guns up aloft, and there's a terrific tumble into this channel. We've dragged, or, rather, swung round our anchor."

"But we are safe enough?" asked Vernon.

"Yes, safe," replied Hans. "Too safe; we cannot break out our anchor. They are sending a diver to see what is amiss."

Evidently the diving arrangements on board were not considered to be of a confidential nature, for Hans led the way to the compartment under the fore-hatch, without the lads being sent back by the significant word "verboten".

A man was preparing for a submarine walk. He was already dressed in an india-rubber suit, with leaden weights attached to his chest, back, and boots. Two others were standing by, ready to place the helmet over his head, when Leutnant Rix had finished giving him minute directions.

The officer spoke rapidly and in a low tone. Ross could not catch all he said, but the words "gefährliche Strömungen" (dangerous currents) and "Der Wendepunkt der Flut" (slack water) and "Drei Viertel funf" (a quarter to five) occurred frequently.

Vernon glanced at his watch. It was then a minute after four. Apparently Rix was impressing upon the man that he must clear the anchor at slack water, which occurred at a quarter to five.

The two attendants then proceeded to place the diver's helmet on his head. The lads noticed that it had neither air-tube nor telephone wire. Nor was there a life-line attached to his waist. Fresh air was obtained from a metal case strapped to his back. The man was able to work independently, and without having to rely upon his air supply from the submarine.

The oval door in the diving-chamber was thrown open. The diver entered, and the water-tight panel was quickly replaced. One of the seamen thrust over a short lever, and immediately water rushed into the small compartment. As soon as the space was filled the diver was able to open a similar door in the outer plating of the submarine, and thus gain the bed of the sea.

Presently Leutnant Rix turned, and saw for the first time that Ross and Vernon were discreetly standing in the background.

"Go away. It is forbidden!" he shouted angrily.

They obeyed promptly, retreating to the space allotted to the crew, since it was neither desirable nor possible to return to their bunks.

For some minutes the luckless Hans Koppe was subjected to a severe dressing-down by his hot-headed officer, and when at length the seaman rejoined the lads he was in no humour to resume conversation.

Slowly the minutes sped. The submarine was still rolling sluggishly, in spite of the fact that more water had been admitted into the ballast tanks.

The men were talking seriously amongst themselves. From scraps of conversation that drifted to the lads' ears, it was evident that they had grave doubts concerning the ability of the diver to perform his task, and even of his chances of regaining the submarine, owing to the violent disturbances of the water.

Presently the motion of the anchored submarine became more acute. A weird grating sound—the noise made by the hull rasping over the bed of the sea—was distinctly audible.

One of the seamen produced
