These trawlers were undoubtedly both a valuable protection to the fishermen (who had been repeatedly attacked by the enemy) and a subtle trap for some of the less experienced submarine captains. During May two more trawlers, the _Strathallan_ and _Strathearn_, were similarly commissioned, and even steam drifters such as the _Fort George_ (armed with one 6-pounder) were employed in this kind of work. On the thirteenth of June _Strathearn_ was fishing 19 miles east of the Bell Rock when five shots were fired at her, presumably by a submarine, though owing to the hazy weather nothing could be seen. The enemy then evidently sighted a destroyer and disappeared. On the following day _Fort George_ was fishing about 35 miles east of May Island, when she was attacked by submarine at 2,000 yards. It was ten o’clock at night, and the drifter, after the third round, secured her fishing gear and returned the fire. The enemy was evidently surprised, for after the drifter had fired three shells the German broke off the engagement and submerged, but with his fourth and fifth rounds he had hit _Fort George_, killing two and wounding another couple. But on the following twenty-eighth of January _Fort George_ was about 14 miles east of May Island, with the decoy trawler _W. S. Bailey_ (Lieutenant C. H. Hudson, D.S.C., R.N.R.). The two ships were listening on their hydrophones when a submarine was distinctly heard some distance away, and it was assumed that the enemy was steering for May Island, so the _W. S. Bailey_ after proceeding for a quarter of an hour in that direction listened again, and the sounds were heard more plainly. For an hour and a half the enemy was determinedly hunted, and just after 9 p.m. the sounds became very distinct, so the trawler steamed full speed ahead in the submarine’s direction, dropped a depth charge, listened, and then, as the enemy was still heard on the hydrophone, a second charge was dropped. The trawler then went full speed astern to check her way, and just as she was stopping there were sighted two periscopes not 20 yards away, on the starboard quarter, and going full speed. The trawler then dropped a third depth charge over the spot where the periscopes had disappeared, and nothing further was heard on the hydrophone, but a fourth charge was then let go to make sure, and the position was buoyed, and the disguised craft remained in the vicinity until January 30. A few days later the _W. S. Bailey_ swept with her chain-sweep over the position, and on each occasion the sweep brought up in the place that had been buoyed, and a quantity of oil was seen. Local fishermen accustomed to working their gear along this bottom reported that the obstruction was quite new. In short, the _W. S. Bailey_ had succeeded in destroying UB 63, a submarine about 180 feet long and well armed with a 4·1-inch gun and torpedoes. For this useful service Lieutenant Hudson received a bar to his D.S.C., while Skipper J. H.
