It is not to our purpose to enumerate successful shots of the simple and easy kind; one or two examples will stand for a number of these. C. 15, for instance, sighted an enemy submarine at 2.43 on a November afternoon, dived and flooded tubes; sighted the U-boat again in the periscope at 3.12; at 3.15 fired at 400 yards. The noise of the explosion was slight, but the enemy--U.C. 65--sank immediately, and C. 15 picked up five survivors. D. 7, Commander C. G. Brodie, sank U. 45 only twenty-two minutes after sighting her, at a range of 1,200 yards. Lieutenant A. W. Forbes, in C. 7, sighted a large U-boat on his port quarter, at 3.32 A.M. of a dark and misty April night. He immediately attacked on the surface, and sank her with a single shot at 400 yards. These prompt and successful shots deserve full credit; but every now and then some exceptional circumstance will add a special reason for satisfaction. For example, it is always good to catch a pirate red-handed. Lieut.-Commander G. R. S. Watkins, in E. 45, was beginning his day’s patrol at 6.15, on a dim October morning, when he observed flashes on his starboard bow. He altered course in that direction, and after five minutes sighted an unhappy merchantman under fire from a U-boat. He dived at once and approached. At 6.37, he was near enough to see through his periscope that the vessel was a steamer with Dutch colours painted on her side. She was a neutral, and of course unarmed, but such considerations meant nothing to the U-boat pirate, who had ceased fire and was coolly waiting for his victim to sink. He was a large submarine, partially submerged, and by way of further caution he was steering about in figures of 8, with his gun still manned. But, for all his caution, just retribution was upon him. Lieut.-Commander Watkins fired his first shot at 400 yards, and missed--altered course instantly, and in little more than three minutes fired again, from a new angle, two shots in rapid succession. Thirty seconds afterwards, justice was done in full; a loud explosion was heard and there was a tremendous convulsion in the water. For the moment, E. 45 was blinded--her periscope was submerged. With a rebound she came to the surface, saw in one quick glance that her enemy was destroyed, and sank again to 60 feet. When she had reloaded, and returned finally to the surface, both pirate and Dutchman had disappeared into the depths. [Illustration: ‘Was steering about in figures of 8, with his gun still manned.’]
