The Submarine Hunters

"We must sacrifice the lot, Herr Rix," decided Kapitan Schwalbe. "There is no time to lose. Storm or no storm, we must slip and run for it."

It was U75's only chance, but it left her with only a small stockless kedge-anchor and chain, insufficient to withstand a heavy strain.

The compressor was released. With a loud rumble, for every sound was magnified within the confined space, the rest of the cable was allowed to take charge. It did so promptly, the end of the chain giving the hull a defiant smack as it did so. U75, no longer held by her anchor, began to drift with the tide, scraping dismally over the bed of Helwich Channel.

Schwalbe was now back at his post in the conning-tower. He dare not take the submarine to the surface until he had put a safe distance between him and the anchored British warship. Nor did he care to order the ballast tanks to be blown. Rather than allow the "pumping" of the seas to hammer the submerged craft upon the hard sand, he preferred to take the risk of letting her drag.

Fortunately the tide set evenly along the bed of the channel. A cross-current would have set the submarine upon the jagged rocks of the hidden West Helwick Ridge. Nevertheless there was always the danger of being hurled violently against a detached rock, or of fouling a live mine if by chance the British had laid obstructions in the channel.

Both Ross and Vernon knew the danger, but, manfully concealing their misgivings, they watched the faces of those of the crew who were "watch below". Most of the men were Frisians, broad-shouldered, blonde-featured, and generally devoid of fear. Yet the ceaseless strain upon the nerves had already begun to tell. As hardy fishermen, they would not have hesitated to launch their open boats in a storm to go to the rescue of a hapless vessel aground on the grim sand-banks of the Frisian shore. As the conscript crew of the submarine, compelled to keep within the limits of a steel box that almost momentarily threatened to be their tomb, their natural bravery was quenched.

Many of them sat upon their lockers, stolid-faced men who had already tasted of the bitterness of death. Others showed unmistakable signs of excitement, bordering on frenzy. They dreaded their life of modern piracy. The idea of sinking hapless merchantmen was repugnant to them, for they understood the brotherhood of the sea. It would be different if they were called upon to attack an armed British ship of war. They had no option but to obey their junker officers, who in turn were compelled to accept the misguided orders of the arch-pirate, von Tirpitz.

They were disheartened, too, for reports, in spite of the vigilance of the officers to conceal them, had reached them of the losses inflicted upon other unterseebooten. Occasionally they heard of a submarine crew being saved, but generally it was a case of total loss of all on board, by some hitherto unknown means, at the hands of the British Navy.

A hand touched Ross lightly on the shoulder. Turning, he saw Hans Koppe standing in a darkened corner of the compartment.

"Can you tell me this, mein herr?" asked the seaman in a low tone. "Is it true that the English give no quarter to German seamen in submarines?"

"I shouldn't think that they would refuse to do so," replied Trefusis. "Of course, I can quite understand that an opportunity doesn't often occur; but I've heard of several instances in which your U-boats have surrendered, and the crews have been treated exactly the same as other prisoners of war."

"I have heard differently," said Hans, "but I hope it's a mistake. I have a feeling that we won't see Wilhelmshaven again. And I have a wife and six children at Flensburg. Our Kapitan, too, expects that we might be denied quarter, because we have sunk your merchantmen. Believe me, I regret having done so, but we have orders. Do you know why Kapitan Schwalbe took you on board?"

"Because a certain German agent wanted us out of the way, I suppose," replied Ross.

"Perhaps," admitted Hans Koppe. "But in the event of our being captured he thinks that his good treatment of you will be in his favour. We are, I do not mind telling you, in a very tight corner. Our fuel supply is almost run out. We cannot hope to return home by way of the Straits of Dover. Not one of our submarines has tried that passage of late without meeting with disaster—at least, so I heard der Kapitan tell der Leutnant. Ach! It is deplorable, this war."

The rapid ringing of a gong was the signal for the watch below to turn out. A peculiar hissing noise proclaimed the fact that the ballast tanks were being emptied. U75 no longer grated over the bottom; her motors were running almost dead slow.
