and six months' pay to spot one this journey. It would be some find."
The observer did not reply immediately. He was keenly searching the opposite shore to find the breakwater at the entrance to Boulogne harbour.
"Can you see it yet?" called the pilot, noting an anxious look on Jock's face. "Yes," replied the latter. "Better give her another two points south, and then we shall just about hit the canal below the town. Our instructions were to follow it to the main aerodrome."
"Aye, aye," answered the pilot, altering the controls slightly, and bringing her head round upon a more southerly course.
Shortly after this, the town and harbour of Boulogne came into full view to the naked eye. Their intention was to leave it a little on their left, and, then making a landfall of a certain railhead and canal, take a short cross-country flight to the big aerodrome behind the British lines. They now began to regard themselves as nearly at the end of their journey, and had no expectation of a still greater adventure before them–an adventure which would prevent them reaching their destination, at any rate, that day.
Only some five or six miles of sea now lay between them and the land, and they were right over the track of the transports, which made a continuous line of traffic between the two shores, when Fisker, who had taken up his glasses again in order to watch a batch of troopships, escorted by a couple of destroyers, suddenly turned them on to a large four tunnelled hospital ship, which, coming out of the harbour, crowded with wounded and war-worn men, was ploughing its solitary way towards Old Blighty, without any other escort or protector than the Red Cross flag.
Suddenly, as he watched the stately vessel moving along at twenty-five knots, with the huge combers falling away from her bow, and a long milk-white trail from her stern, he started suddenly, and lowered his glasses, almost shrieking at the top of his voice:–
"See there, Dastral! Quick!"
"Where away?" cried the pilot, turning round sharply, and catching a glimpse of Fisker's horrified face.
"There!" exclaimed the observer, laconically, pointing with his hand in the direction of the hospital ship.
Dastral looked in the direction indicated.
"The brutes!" he gasped. "Not if I can prevent it."
That which had called forth these horrified expressions was nothing more or less than a lurking German submarine, hidden beneath the water, but with a few inches of periscope above the surface, manoeuvring to bring the huge hospital ship within its range. It had evidently watched the procession of transports pass by, but, fearing that it might be rammed by one of the destroyers if it revealed its presence, it had waited for some other tasty morsel to come along. Unfortunately, there was nothing she could touch but this hospital ship.
With any other nation, a vessel flying the sacred emblem of humanity, which floated from the masthead of the ship, would have been immune from attack. But to the Hun no code of morals seems to hold good. Nor was any crime to be regarded as such if only some damage could be inflicted upon the enemy.
"Ach, wohl, mein herr!" the German ober-lieutenant in the submarine was remarking to his superior officer at that moment. "The verdomt transports are gone, and there's nothing but a big 'hospital ship steaming by. Shall we loose a leetle tin fish at her? You can't trust these English; they're probably transporting materials of war. There are sure to be some staff officers on her decks anyhow. What say you, mein herr?"
"Sink the blamed hooker, Fritz! We can say that she tried to ram us, when we make out our report. No one will be any the wiser, for dead men can't tell tales. He, he! Ho, ho!"
And already the commander's hand was upon the lever in the conning-tower which controlled the torpedo tubes in the bow. Hesitating just for a second, as though battling with the last shreds of a lingering conscience, he pulled the lever.
"Swiss-s-s-h!" came the sound as the deadly missile left the tube and entered the water.
"Good heavens! She's fired!" exclaimed both the aviators, as, in the very middle of a dangerous nose dive they saw what had transpired, and followed for an instant, even in that downward dive, the wake of the deadly torpedo.
Fortunately, at that very moment the captain of the Galicia, the big four-funnelled boat, having had his attention attracted to the spot by the nose-dive of the warplane, saw the periscope of the enemy's submarine, and, starboarding his helm, swung the huge vessel just sufficiently to port for the first torpedo to miss his stern by a few feet.
Then commenced a stern chase, for the Galicia, seeing the imminent danger that she was in, sought refuge in flight. Placing her stern towards the oncoming submarine, she fled down Channel, hoping thereby to save her precious cargo of wounded heroes.
"Donner and blitz!" exclaimed the commander to his lieutenant. "We have missed her. That will never do. We must sink her now at any cost, or the American cables will be full of the affair, and the anger of the neutral world will be turned against us once more."
"What shall we do, mein herr?" asked the lieutenant of the submarine. "She can do twenty-five knots and we can only do seventeen while we are submerged."
"We must run her awash, and give her three-inch shells with the deck guns. The transports and patrols are some distance off now."
"She will be calling back the destroyers by now with her wireless, mein herr."
"Gott in Himmel! but we must risk it. There may just be time. I wish we had let the blamed hooker go by."
Then, with a few round oaths, he switched down the periscope, pulled over the lever that drove the water out of the ballast tanks, and, as the boat came to the surface, he had the hatch unshipped, and ordered his gun crew to stations, calling them dachshunds, and a few more vile names.
As soon as the submarine came to the surface, the electric motors were stopped, and the surface engines started so that every knot could be got out of them.
"All clear!" had been reported to him by the lieutenant, and as regards the narrow horizon which can be surveyed from the periscope of a submerged vessel, all was indeed clear, for they had not seen the hornet which was buzzing overhead, silently dipping and nose-diving with her engines shut off, and rapidly manoeuvring like an angry wasp, waiting but an opportunity to get at its victim.
So intent was the submarine commander upon his prey, with one eye on the hospital ship and another on the horizon, watching for the patrol boats, which he knew would be sure to return, that he had even got his deck-gun to work, and was firing rapidly at the Galicia, when to his dismay he heard, just over his head, the whir-r-r-r-r of the aeroplane, as Dastral started his engine again.
"Mein Gott, was ist das?" he cried.
"Ach, Himmel, but we are lost!" came the cry from the gunners and the ober-lieutenant.
"Dachshunds!–you verdomt fools, turn the gun on the aeroplane!" yelled the irate commander, but he realised that he had lost the game.
Nearer and nearer came that dreaded enemy, with its angry buzz, till but a hundred feet above the broad, whale-like back of the submarine, for Dastral, having but the two twenty-pound bombs in his carrier, determined not to miss his chance.
"Be careful, Jock!" he shouted. "Drop it right on her conning-tower. Take no risks."
"Right-o, old fellow!" Jock had replied, his hand on the bomb release. "She's giving us shrapnel, though. Look out!"
"Spit . . . Bang! Spit . . . Bang!"
