Mr. Jehan might well have been taken by surprise by this sudden meeting at close quarters in the dusk; but he was not. In an instant the White Ensign was hoisted, and he himself was firing his revolver at the officer steering the enemy boat. This was his pre-arranged signal for his mates to open fire, and it was obeyed with deadly quickness and precision. The gun was a mere pop-gun, a 3-pounder, but at the range it was good enough. Of the first three rounds fired, the first and third pierced the centre of the enemy’s conning-tower and burst inside, while the second struck the after part of the same structure and carried it away, ensign and all. The officer fell overboard on the starboard side. The submarine was now out of hand. The tide brought her close round _Inverlyon’s_ stern, within ten yards, and the gun was instantly slewed on to her again. This time, six rounds of extra-rapid fire were got off. The first hit the conning-tower, the second and fourth went over, the third, fifth and sixth hulled the U-boat dead. She sank, with the same ominous nose-dive, her stern standing up at an angle of 80°. The swirl was violent, and in it three bodies were flung to the surface. A shout was heard from one of them--a pirate, but a man in agony. Skipper Phillips stripped, took a lifebuoy in his arms and leaped overboard. He swam strongly, but vainly, in that rush of wild water and oil, and at last had to be dragged home on his own buoy. The smack meantime was drifting over the dead submarine, and brought up when her trawl got fast upon it. The trawl was even more useful in another action, where it actually brought on the fight at close quarters and made victory possible. One day in February, H.M. Trawler _Rosetta_, Skipper G. A. Novo, R.N.R., had gone out to fish, but she had on deck a 6-pounder gun concealed in an ingenious manner which need not be described. She joined a small fleet of four smacks and two steam trawlers some forty-five miles out, and fished with them all night. Before dawn next morning a voice was heard shouting out of the twilight. It came from one of the steam trawlers: ‘Cut your gear away! there’s a submarine three-quarters of a mile away; he’s sunk a smack and I have the crew on board.’
