CHAPTER XVI CAPTIVES IN A SUBMARINE ON being hauled on board the German submarine Fuller and Kirkwood were sternly ordered to go below, their captors indicating a small hatchway fifteen feet for'ard of the conning-tower. The prisoners had no option. They descended the almost vertical steel ladder and found themselves in practically the bow compartment of the vessel. It was the crew space of the submarine mine-layer, for the craft, on which was painted the number UC49, was not fitted with torpedo tubes, nor did she carry guns of the "disappearing mountings" type. Her part was to sneak out of the Elbe, cruise on the surface whenever practicable, diving only when any strange vessel hove in sight. Her cargo had consisted of forty metal cylinders stowed aft--mines of the most recent type--but having sown her harvest of death and destruction, regardless whether an enemy or a neutral vessel fell a victim to the deadly peril, she was on her way back to the Fatherland. The compartment in which Fuller and his companion found themselves was about thirty feet in length and fifteen at its maximum diameter, which was at the after end. For'ard it tapered, at first gradually, then sharply, until it terminated at a bulkhead close to the bows. In the lower part of the recess were the anchors and cables, capable of being lowered or hauled by means of elaborate mechanism which was controlled from within. The upper portion of the bow compartment consisted of a large fresh-water tank. Round the crew space were lockers that served a double purpose: besides containing the effects of the men they were used as seats. Hooks were bolted to the cambered deck-beams in order to sling hammocks--in fact, half a dozen hammocks were at that time occupied--and mess-tables. Against the after bulkhead was a small partitioned-off place that served as the cook's galley, the stove being heated by electricity. While running awash the fumes were carried off by means of a funnel that projected a few inches above the deck, which was fitted with a watertight cover that could be operated from the conning-tower when the submarine was trimmed for diving. Yet in spite of the ventilation the place reeked vilely of a variety of odours. Fuller wondered what the atmosphere must be like when UC49 was submerged. In addition to the sleeping occupants of the hammocks, who by their restlessness even in slumber showed signs of the mental strain, the crew space was occupied by three fairhaired, fresh-featured Frisians, who regarded the captives with scant curiosity and, after the first five minutes, seemed to ignore the Englishmen entirely. "May as well make the best of things," remarked Fuller. "I know the ropes a bit--been through it before. Take your wet clothes off, old man. Keep a tight hold of your personal gear. We'll see if we can't persuade that fat chap in the galley to put our things to dry." "They would dry on us in this hot show," observed Kirkwood. "Suppose we are sent for?"
