said d.i.c.k. "If we had known of this before, it would have saved no end of work. There would have been no need to have destroyed every gun singly."

"Can't say I envy the fellow who has to fire the stuff," added Sefton.

"h.e.l.lo, what's that?"

The noise of the detonating charges had ceased. Instead came the unmistakable crackle of rifle-firing.

"Look alive!" ordered the Sub. "Our fellows are being attacked."

Brushing aside the canvas screen the two officers made their way along the tunnel as swiftly as the dancing beams of the midshipman's torch permitted.

Before they reached the rise leading to the open air there was a terrific concussion. A waft of hot, pungent fumes bore down upon d.i.c.k and his companion. They were compelled to stop, almost choking in the stifling atmosphere. The rays from the torch failed to penetrate the dense brownish cloud of smoke and dust.

"Carry on," spluttered d.i.c.k; then noticing that the midshipman seemed on the point of asphyxiation, he seized the torch and, dragging his companion, made for the open air.

Suddenly he came to an abrupt halt. The gap between the crumbling walls no longer existed. They were trapped.

CHAPTER IV

Trapped in the Magazine

For some moments Crosthwaite stood stock-still. His senses were temporarily disorganized by the appalling discovery and by the acrid fumes. It was not until he felt Sefton's shoulder sink under his grasp that he realized the lad had collapsed.

Holding the torch in his left hand, d.i.c.k seized the midshipman by the strap of his field-gla.s.ses. Luckily the leather stood the strain well.

Keeping his lips tightly compressed, the Sub, bending as he made his way through the fumes, dragged his companion back along the pa.s.sage.

He felt like a man who has dived too deeply. He wanted to fill his lungs with air, yet he knew that to attempt to do so might certainly end in disaster. The midshipman's inert body, which at first seemed hardly any weight to drag, now began to feel as heavy as lead. Once or twice the Sub stumbled, the effort causing his lungs to strain almost to bursting-point. It required all his self-control to prevent himself relinquishing his burden and jumping to refill his lungs with air which was so heavily charged with noxious fumes.

At length he reached the canvas screen, that, having teen soaked in water by the Turkish ammunition party, was still moist. With a final effort he thrust the curtain aside and took in a deep draught of air.

It was comparatively fresh. The poisonous gases had failed to penetrate the close-grained fabric. Then, overcome by the reaction, d.i.c.k stumbled and fell across the body of his companion.

How long he lay unconscious he knew not, but at length he was aroused by Sefton vigorously working away at the exercises for restoring to life those apparently drowned. Half-stupefied, the Sub resented. He was under the vague impression that he was in the gun-room of the _Hammerer_ and that the midshipmen were playing some practical joke.

Then he began to realize his surroundings.

The torch was still alight, but already the charge showed signs of "running down". The air, although close, was not heavily impregnated with fumes. No sound penetrated the rock-hewn vault.

"Buck up, sir!" exclaimed Sefton with a familiarity engendered by the sense of danger. "We'll have to get out of this hole as soon as we can. Are you feeling fit to make a move?"

d.i.c.k sat up. His head was swimming. His limbs felt numbed. He wondered why he had been in an unconscious state longer than his companion, until he remembered that throughout that terrible journey along the gas-charged pa.s.sage Sefton had been dragged with his head close to the ground. Consequently, owing to the fumes being lighter than the air, he was not so badly affected. For another reason: when d.i.c.k collapsed, his weight falling across Sefton's body had acted very efficiently in expelling the bad air from the midshipman's lungs, and as the Sub rolled over the subsequent release of pressure had allowed a reflux of comparatively pure air to take the place of that pumped out of Sefton's chest.

"Can't hear any firing," remarked Sefton. "I suppose our fellows have beaten them off."

d.i.c.k did not reply. He did not want to raise false hopes. He remembered the strict orders issued to the officers of the demolition party, that in the event of a counter-attack by the Turks they were to fall back immediately upon the boats, and allow the guns of the fleet to deal with the enemy. Yet it seemed strange that there were no sounds of firing, unless some time had elapsed and during that interval the _Hammerer_ and her consorts had completely dispersed the Turkish infantry.

"Light won't last much longer," declared Sefton laconically. "What's the move, sir?"

d.i.c.k moved aside the curtain. The air in the pa.s.sage was now almost normal. There was no longer any danger of asphyxiation.

Retracing their way along the pa.s.sage, the two young officers made the disconcerting discovery that the tunnel was completely blocked for the last twenty feet towards the entrance. They stood in silence, till d.i.c.k flashed the light upon his companion's face. The midshipman's features were perfectly calm.

"A pretty mess up!" he exclaimed, and the two laughed; not that there was cause for mirth, but merely to show each other that they were not going to accept their misfortunes in fear and trembling. "Let's try shouting."

They shouted, but beyond the mocking echo of the voices no rea.s.suring call came to them in return.

"Our fellows have been over-zealous with the gun-cotton," observed Sefton. "They'll miss us presently, and then they'll have a job to dig us out."

But Crosthwaite had other views on the situation, and these were much nearer the mark.

The rifle-firing he had heard that of the demolition party, who in the course of their operations had been attacked by overwhelming numbers of Ottoman troops.

Acting upon instructions the Lieutenant-Commander in charge ordered a retirement. Leaving a section in reserve to cover the retrograde movement, the bluejackets with very little loss descended the steep side of the hill and re-embarked. Then, covered by the guns of the fleet, the rear-guard successfully retired, in spite of a galling fire from a battery of field-pieces that the Turks, under German officers, had brought up.

One of the sh.e.l.ls from these guns had resulted in the subsidence of the already tottering masonry, and had effectively imprisoned Sub-lieutenant Crosthwaite and Midshipman Sefton in the magazine.

It not until the _Hammerer's_ men fell in on the beach that the two officers were missed. Someone suggested that they might be with the rearguard, now descending from the demolition fort, but inquiries proved that this was not so.

As one man the landing-party of the _Hammerer's_ crew volunteered to return and search for their missing officers. Reluctantly the Lieutenant in charge had to refuse their request. Orders had to be carried out to the letter. Grave consequences might ensue if the devoted bluejackets returned to the scene of action. Not only would they risk their lives in an attempt that might be futile, but the fire of the fleet might be seriously interfered with.

So the boats returned to their respective ships, and Sub-lieutenant Richard Crosthwaite and Mr. Midshipman Sefton were duly reported as missing.

"Let's explore," suggested d.i.c.k. "It's no use sitting down and killing time. Let's make ourselves useful and explore while the torch lasts.

I suppose you haven't another refill?"

"Half a dozen in my chest, but that's not here," replied the midshipman. "By Jove, I do feel stiff! Why, my jacket's torn, and I've grazed my knee."

"I'm afraid I must plead guilty to that, Sefton," replied d.i.c.k. "I had to get you along somehow, and there wasn't time for gentle usage."

"I wondered how I got there," declared the midshipman. "Everything seemed a blank. By Jove, sir, you saved my life!"

"I may have had a hand in it," admitted d.i.c.k modestly. "Now, suppose we bear away to the left?"

They had regained the central portion of the subterranean works, and were confronted by two small pa.s.sages, one leading to the left and the other to the right, both diverging slightly. The one the officers followed was not zigzagged, showing that it did not communicate with the open air. d.i.c.k proposed that they should abandon their efforts in this direction and explore the right-hand pa.s.sage.

"I'm game," a.s.sented Sefton. "Yes, this looks promising; it twists and turns as if it were intended to stop the splinter of any sh.e.l.l that happened to burst at its mouth."

"No go here!" exclaimed the Sub after traversing about twenty yards.

"This has been bashed in. We must thank our 12-inch guns for that.

The magazine evidently served the quickfirers both of the north and south bastions. The question is, what is the third pa.s.sage for?"

"We'll see," replied the midshipman, regarding the rapidly failing light with considerable apprehension.

The tunnel ran in an almost horizontal direction for fifty paces, then gradually descended in a long, stepless incline.

"Steady!" whispered Crosthwaite, laying his hand on Sefton's shoulder and at the same time switching off the torch. "I hear voices."

The officers listened intently. At some considerable distance away men were talking volubly in an unknown tongue. More, there was a cool current of refreshing air wafting slowly up the incline.
