‘What had happened? Was it really not the end of us? Was not the water rushing into the boat somewhere, and carrying us down to the bottom? It must have been a mine--a tremendous mine detonation close to the boat. Reports were made automatically from all compartments. “Bow compartment not making water; stern compartment all right; engine-room no water.” No water anywhere! ‘Then the boat inclined itself at a peculiar angle--the bow went down and the stern rose up. The boat was unaccountably trimmed by the bow, although the hydroplanes were hard over in the opposite direction. ‘“There is something wrong, sir,” reported the man at the diving-wheel. “The boat won’t answer to her helm. We must be hung up somewhere, by a rope, or perhaps a net!” ‘The devil! We are in a net, of course, and above us there are mines secured to the net. It is enough to drive one out of one’s mind. ‘“Pay attention!” I shouted from the conning-tower. “We have got to get through! Hydroplanes hard up and hard down, utmost speed ahead with both engines! Don’t let her rise! Whatever happens, keep down! There are mines above us!” ‘The engines started, revolving at their highest revolutions. The boat shot forward, caught in the net, strained against it, bored itself a way downwards, tugged, tore, and finally left the wire net all ripped apart. ‘“Hurrah! We are free! The boat answers to her helm!” cried the helmsman from below. ‘“Go deeper, dive to 50 metres (164 feet),” I ordered. “This is an evil spot hereabouts--it is hell itself.” ‘I sat down on the life-saving apparatus and buried my head in my hands. Everything was going round with me like a mill-wheel. Above my eyes I had a pain as though needles were sticking into my forehead, and I had such a humming in my ears that I stopped them up with my fingers. ‘“This is certainly an evil spot,” I repeated to myself, “but what luck we had, most extraordinary luck, which has saved us!” ‘Some time elapsed before the pains in my head allowed me to fit things together and understand what had happened. Yes, it was pure luck that we had dived just in time. We were at a depth of 17 metres when the explosion occurred, our bows touching the net. Things grew clearer and clearer to me as I thought them over.
