"Ammunition hoist damaged, sir," replied the Sub.

"Any casualties?"

"No, sir."

"Then stand by."

Dick heard the whistle replaced in the tube as the officer completed his enquiries. Then hard-a-port the Hammerer described a semicircle, in order to bring her as yet unengaged starboard battery into action.

By this time the Turkish reply was but a feeble one. Pounded by the direct fire from the pre-Dreadnoughts; shattered by the long-range high-angle fire of the Queen Elizabeth and the Invincible, the forts were little better than mounds of rubbish.

Already the British warships had penetrated more than two miles up the formidable Straits, the mine-sweepers performing their difficult task with the utmost coolness and bravery. Night was coming on. All that could be done was to make sure of the complete reduction of the southernmost forts, and continue the sweeping operations as a prelude to a farther advance on the morrow.

Two British seaplanes, hovering at a height of nearly a thousand feet above the hostile positions, reported by wireless that the Turks were abandoning their shattered forts. The opportunity had arrived to consummate the day's work. A signal was made from the flagship to land armed parties. Joyfully the order was received, for the British seaman is not content with doing a lot of damage from afar; he must needs see for himself the result of his efforts.

Still maintaining a steady fire with their secondary batteries, the ships proceeded to hoist out their boats. Into these dropped seamen and marines, armed with rifles and bayonets, Maxims were passed into the boats, and charges of gun-cotton carefully stowed away for future use in completing the destruction of the Turkish guns.

"At this rate we'll be through in less than a week," remarked Midshipman Sefton to Dick, as they sat in the stern-sheets of a launch packed with armed seamen. The launch was in tow of a steam pinnace, while astern of her were two more boats, equally crowded.
