The path Dick had indicated was the one by which the field-pieces had been lowered from the higher ground. It was obstructed in several places by craters torn by the explosion of the British shells, but these afforded no difficulty to the bluejackets.

Wellnigh breathless with their exertions, they reached the fort only to find, to their chagrin, that they had been forestalled by their friendly rivals, for the British flag floated proudly on the captured position.

So devastating had been the fire from the ships that the fort was little better than a shattered heap of brickwork and masonry. Armour-plated shields had been rent like paper, guns of immense size been dismounted and hurled aside like straws. Bodies of the devoted Ottoman garrison lay in heaps. Everything was smothered with a yellowish hue from the deadly lyddite and melanite. Yet several of the huge 80-ton guns were seemingly serviceable. These had to be rendered totally useless by means of slabs of gun-cotton placed well within the muzzle and fired electrically.

Sub-lieutenant Crosthwaite was studiously engaged in making a rough plan of the fort when Sefton, his soot-grimed face red with excitement, approached him.

"I believe I've found a magazine or something, sir," he exclaimed. "It's a funny sort of shop—like a tunnel. There are half a dozen Turks there——"

"Eh?" ejaculated Dick incredulously.

"Dead as door-nails," Sefton hastened to explain. "They look as if they had been suffocated. But the air's pure enough down there now."

Placing his notebook in his pocket, the Sub walked with Sefton across the littered open space in the centre of the fort till they came to a salient angle that faced the northern or landward side. Here the rubble rose to a height of about twenty feet. In places the wall, composed of armour-plate and concrete, had been riven from top to bottom, huge slabs of masonry being held up only by mutual support. On the top of the debris were half a dozen bluejackets, taking advantage of the daylight that still remained in flag-wagging a message to one of the destroyers.

"Here's the show," announced Sefton, pointing to a narrow passage between two immense artificial boulders.

At one time the opening had been much wider, and had been provided with stone steps, but the irresistible shock had contracted the passage, and had buried most of the steps under a heap of rubble.
