Without troubling you with precise figures, I may say that they represented roughly a twenty-five per cent. advance up on the older boats, and were fitted with several auxiliary engines which were wanting in the others. At my suggestion, instead of carrying eight of the very large Bakdorf torpedoes, which are nineteen feet long, weigh half a ton, and are charged with two hundred pounds of wet gun-cotton, we had tubes designed for eighteen of less than half the size. It was my design to make myself independent of my base.

And yet it was clear that I must have a base, so I made arrangements at once with that object. Blankenberg was the last place I would have chosen. Why should I have a port of any kind? Ports would be watched or occupied. Any place would do for me. I finally chose a small villa standing alone nearly five miles from any village and thirty miles from any port. To this I ordered them to convey, secretly by night, oil, spare parts, extra torpedoes, storage batteries, reserve periscopes, and everything that I could need for refitting. The little whitewashed villa of a retired confectioner--that was the base from which I operated against England.

The boats lay at Blankenberg, and thither I went. They were working frantically at the defences, and they had only to look seawards to be spurred to fresh exertions. The British fleet was assembling. The ultimatum had not yet expired, but it was evident that a blow would be struck the instant that it did. Four of their aeroplanes, circling at an immense height, were surveying our defences. From the top of the lighthouse I counted thirty battleships and cruisers in the offing, with a number of the trawlers with which in the British service they break through the mine-fields. The approaches were actually sown with two hundred mines, half contact and half observation, but the result showed that they were insufficient to hold off the enemy, since three days later both town and fleet were speedily destroyed.

However, I am not here to tell you the incidents of the war, but to explain my own part in it, which had such a decisive effect upon the result. My first action was to send my four second-class boats away instantly to the point which I had chosen for my base. There they were to wait submerged, lying with negative buoyancy upon the sands in twenty foot of water, and rising only at night. My strict orders were that they were to attempt nothing upon the enemy, however tempting the opportunity. All they had to do was to remain intact and unseen, until they received further orders. Having made this clear to Commander Panza, who had charge of this reserve flotilla, I shook him by the hand and bade him farewell, leaving with him a sheet of notepaper upon which I had explained the tactics to be used and given him certain general principles which he could apply as circumstances demanded.

My whole attention was now given to my own flotilla, which I divided into two divisions, keeping Iota and Kappa under my own command, while Captain Miriam had Delta and Epsilon. He was to operate separately in the British Channel, while my station was the Straits of Dover. I made the whole plan of campaign clear to him. Then I saw that each ship was provided with all it could carry. Each had forty tons of heavy oil for surface propulsion and charging the dynamo which supplied the electric engines under water. Each had also eighteen torpedoes as explained and five hundred rounds for the collapsible quick-firing twelve- pounder which we carried on deck, and which, of course, disappeared into a water-tight tank when we were submerged. We carried spare periscopes and a wireless mast, which could be elevated above the conning-tower when necessary. There were provisions for sixteen days for the ten men who manned each craft. Such was the equipment of the four boats which were destined to bring to naught all the navies and armies of Britain. At sundown that day--it was April 10th--we set forth upon our historic voyage.

Miriam had got away in the afternoon, since he had so much farther to go to reach his station.
