A division of four drifters--_Young Fred_, _Pilot Me_, _Light_, and _Look Sharp_--under Lieutenant Thomas Kippins, R.N.R., was patrolling one afternoon in April, when at 5.25 P.M. Skipper Andrew Walker, R.N.R., sighted a periscope about 150 feet away on the starboard quarter of his ship, _Pilot Me_. He immediately altered course to starboard, and the submarine thereupon submerged entirely. Skipper Walker passed over the spot where she was last seen and dropped a depth-charge, altered course rapidly and dropped another, fired a red rocket to warn the division, dropped a third and fourth depth-charge, and hoisted the signal asking his commander to come north at full speed. He then stopped his engines and listened on his hydrophone. Hearing no sound, he made for _Young Fred_, who had altered course and was now closing him. When the two boats were only 300 yards apart, the submarine came to the surface right between them. She rose at an angle of 45°, bows up, and hung so for about two minutes, during which _Pilot Me_, _Light_, and _Look Sharp_ all opened fire, and the two last claim to have hit her. At any rate she went down again, stern first; but Lieutenant Kippins, who was steaming straight for her in hope of ramming, was not disposed to take any chances. He took _Young Fred_ exactly over her, dropped two depth-charges and passed on. The explosion which followed was a very heavy one; the fountain of water which rose was mast high and completely hid the drifter flagship from her companions, who thought for a moment that she ‘had gone.’ The Chief Skipper was far from gone. The spray was hardly off his deck, and the _Young Fred_ was still rocking, when he turned again and then again, dropping two more depth-charges, and ordered _Pilot Me_ to put down a Dan buoy to mark the position. This was done, but it was but marking a grave. H.M.S. _Express_, who had received a wireless signal and hurried to the spot, reports that she found the sea covered with oil, which had extended in a long stream to the northward on the ebb tide. Thick oil was still rising to the surface, and there were streaks of dark brown colour, very noticeable, and distinct from oil. Even when four miles to leeward, whilst approaching, the new comers had been struck by a very strong smell of petrol, which naturally gave them hopeful expectations.
