At length the interchange of gunnery ceased. Towards evening the battery returned, minus one gun, while several of the artillerymen bore traces of being badly knocked about. From six to sunset wounded Turkish troops began to pour into the fort, some hardly able to walk. Yet no attempt was made to alleviate their pain. They were simply ordered to their barrack-rooms, and had to rely upon their own efforts and those of their comrades to attend to their wounds. As soon as it grew dark, Dick and his companion in misfortune threw themselves upon their straw beds. Being unprovided with lights, they generally turned in at sunset and talked until overtaken by sleep. They had not been lying down for more than ten minutes when the door opened, and the German Major, accompanied by a subaltern, entered. They had evidently come straight from the scene of action, for they wore long grey coats bespattered with mud and the yellow stains of lyddite, their faces were grimed with smoke and dust. Each wore a sword under his coat, with the hilt projecting through a vertical slit. The Major also carried a revolver in a holster slung across his left shoulder, and counterbalanced by a sling to which was attached a case containing a pair of binoculars. They were accompanied by a soldier bearing a lamp. This he set down on the floor, and, having saluted, left the room. The subaltern locked the door after him. "Good evening, gentlemen," began the Major in good English which contrasted with the jargon which he had used in his rôle of a Turkish seaman. "We have occasion to do business." "But not with us," added Dick readily. "I think so," corrected the Major. "And you will be glad of it when you hear our proposal. Perhaps you are unaware that to-day the French landed at Kum Kale. We quickly sent them to the right-about, and they had to re-embark in disorder. Unfortunately for us, during the operations two Turkish officers of high rank were taken prisoners and conveyed on board an man-of-war that was covering the re-embarkation of the French troops. I trust I have made myself clear?" "Proceed, then," said Dick. "The loss of these two officers was duly reported to Turkish head-quarters, and Enver Bey immediately telegraphed that we should offer two British in exchange. Would you be willing to sign an undertaking, in the event of your being released, not to take up arms against the Allies?" "That we would not," declared the Sub emphatically. "I thought you would not. A true soldier--whether he be in the Navy or Army--would never do so. Still, the idea occurred to me: a thousand pardons. Now here is a statement for the British Admiral. All you have to do is for both of you to sign your names and add your rank in the space provided, and the exchange will be carried out promptly." The Major produced a folded paper from the breast pocket of his greatcoat, while the subaltern held out a fountain pen. "Why don't you sign?" asked the German.
