The major portion of the casemate was taken up by the gun and its mountings, while a little to the rear of the weapon, and protected by a canvas screen, was the ammunition hoist, by which projectiles weighing 100 pounds each were sent up from the fore magazine. Around the walls were the voice tubes communicating with the conning-tower, the magazine, and other portions of the ship, while in addition was a bewildering array of switches and cased wires in connection with the lighting of the casemate and the firing mechanism of the gun. Buckets of water, for use in case of a conflagration, stood on the floor in close company with a tub full of barley water, at which the parched men could slake their thirst. What little space remained was fully occupied by the gun's crew, who, stripped to their singlets, were coolly speculating as to the chances of "losing the number of their mess". Strangely enough, no one imagined that he was to be one of the unlucky ones; it is always his pal or some of his shipmates. It is an optimism that is shared equally alike by the Tommies in the trenches and the Jack Tars at their battle-stations. Craning his neck, the Sub looked through the gun-port. It was an operation that required no small amount of manoeuvring, for the aperture was barely sufficient to allow the chase of the gun to protrude, while the armoured mounting left very little space between its face and the curved wall of the casemate. The _Hammerer_ was third ship of the port column, for the older battleships were steering in double column, line ahead. Preceding the squadron were the mine-sweepers, covered on either flank by strong patrols of destroyers. Ten or twelve miles to the north could be discerned a mountainous and rocky coast terminating abruptly to the west'ard. Part of the highland was in Europe, part in Asia, but where the line of demarcation existed the Sub was unable to determine. Somewhere in that wall of rock lay the entrance to the Dardanelles, but distance rendered the position of the hostile straits invisible. Away on the port hand lay the island of Imbros. Under its lee could be seen the misty outlines of the _Queen Elisabeth_, _Agamemnon_, _Irresistible_, and the French battleship _Gaulois_, ready to open a long-range bombardment of the Turkish batteries. "Think the beggars will fight when they see this little lot?" asked Midshipman Sefton. "Why not?" asked the Sub. "I hope they will," continued the midshipman. "Especially after all this trouble. The Turk is a funny chap. See how he crumpled up against the rest of the Balkan States in 1912." "On the other hand, the Turkish infantryman in '78 was reckoned one of the best 'stickers' in Europe," said Dick. "Under European officers these fellows will fight pretty gamely, and from all accounts there's a good leavening of German officers and artillerymen in these forts. Anyhow, we've got to get through. We've done it before, you know."
