Time after time the British guns sounded like distant thunder, and shots fell in the vicinity of the Russian ships. Suddenly, as soon as the men were at their quarters, electric signals rang from the conning-tower of the _Admiral Orlovski_, and one of her 56-tonners crashed and roared from her turret, and a shot sped away towards where the light showed. The noise immediately became deafening as the guns from nine other ships thundered almost simultaneously, sending a perfect hail of shell upon the island fort. In the darkness the scene was one of most intense excitement. For the first time the spy found himself amidst the din of battle, and perhaps for the first time in his life his nerves were somewhat shaken as he stood in a convenient corner watching the working of one of the great guns in the turret, which regularly ran out and added its voice to the incessant thunder. CHAPTER XXIX. LANDING OF THE ENEMY AT LEITH. All the vessels were now under steam and approaching Inchkeith, when suddenly two shells struck the _Admiral Orlovski_ amidships, carrying away a portion of her superstructure. Several of the other vessels were also hit almost at the same moment, and shortly afterwards a torpedo boat under the stern of the flagship was struck by a shell, and sank with all hands. Time after time the Russian vessels poured out their storm of shell upon the fort, now only about a mile and a half distant; but the British fire still continued as vigorous and more effective than at first. Again the flagship was struck, this time on the port quarter, but the shot glanced off her armour into the sea; while a moment later another shell struck one of her fighting tops, and, bursting, wrecked two of the machine guns, and killed half a dozen unfortunate fellows who had manned them. The débris fell heavily upon the deck, and the disaster, being witnessed by the spy, caused him considerable anxiety for his own safety. Even as he looked he suddenly noticed a brilliant flash from one of the cruisers lying a little distance away. There was a terrific report, and amid flame and smoke wreckage shot high into the air. An explosion had occurred in the magazine, and it was apparent the ship was doomed! Other disasters to the Russians followed in quick succession. A cruiser which was lying near the Herwit light-buoy blazing away upon the fort, suddenly rolled heavily and gradually heeled over, the water around her being thrown into the air by an explosion beneath the surface. A contact mine had been fired, and the bottom of the ship had been practically blown out, for a few minutes later she went down with nearly every soul on board. At the moment this disaster occurred, the _Admiral Orlovski_, still discharging her heavy guns, was about half-way between the Briggs and the Pallas Rock, when a search-light illuminated her from the land, and a heavy fire was suddenly opened upon her from Leith Fort.
