Adventures are to the adventurous. In less than a month from this event _Farnborough_ was again engaged with a submarine, under circumstances more difficult than the last. One who was present at the engagement described it to me, and though the submarine managed afterwards to reach Germany, she was wounded, and only just escaped total destruction. However, this in no way detracts from the merits of the story, which is as follows: The scene was similar to that of the previous incident, the exact position being Lat. 51.57 N., Long. 11.2 W.—that is to say, off the west coast of Ireland. The time was 6.30 in the afternoon of April 15, 1916, and _Farnborough_ was proceeding northward, doing 5 knots, for Commander Campbell was hoping to intercept a German submarine which had been reported off the Orkneys on the 13th, and was probably coming down the west Irish coast. At the time mentioned the sea was calm and it was misty, but about two miles off on the starboard quarter could be seen a steamer. Suddenly, without warning, between the two ships a submarine broke surface, but Commander Campbell pretended to ignore her until she hoisted the international signal TAF (‘Bring your papers on board’). Owing to the mist it was impossible to distinguish the flags clearly enough to read them. However, Commander Campbell stopped his ship like a terrified tramp, blew off steam, but quietly kept her jogging ahead so as to edge towards the enemy and avoid falling into the trough of the heavy Atlantic swell. There was the submarine lying full length on the surface, about 300 feet long, with a very large conning-tower amidships, one gun forward, one aft, and most of the hull painted a light grey. In reply to the German’s signal _Farnborough_ now kept her answering pennant at the dip and hoisted ‘Cannot understand your signal.’ All this delay was valuable to the Q-ship, for it allowed her to close the range stealthily; and now the submarine also came closer, with her foremost gun already manned. In the meantime, the ‘tramp’ did what she was expected to do—hoisted the signal ‘I am sending boat with ship’s papers,’ and at the same time the bridge boat was turned out (again in command of Sub-Lieutenant J. S. Smith, R.N.R.), and Commander Campbell was seen to hand his papers to this officer to take over to the submarine. It was now 6.40 p.m., and the German fired a shot which passed over the ship, doing no direct harm, but incidentally spoiling the whole affair. The best laid schemes of Q-ship captains, and the most efficient crews, occasionally go astray. One of _Farnborough’s_ people, hearing this gun, thought that _Farnborough_ had opened fire, so accordingly fired also. It was unfortunate, but there it was. This mistake forced Commander Campbell’s hand; he at once hoisted the White Ensign and gave the general order to fire. The range was now about 1,000 yards, and he proceeded at full speed so as to bring his after
