of this ship, but it was quite impossible to see where her big 4-inch and two 12-pounders were located. That being so, it was not surprising that a submarine never suspected on September 9, 1916, that this was another ‘trap-ship.’ It was just before 6.30 in the evening that this steamer was sixty miles south-west of the Lizard, when a submarine was sighted about 2,000 yards off on the starboard bow. The enemy had hoisted some flag signals, but they were too small to be read. It was presumed that it was the usual order to stop, so the steamer hove-to and the captain called up the stokers who were off watch to stand by the lifeboats, for all this time the submarine, who had two guns, was firing at the ship. Having lowered the starboard lifeboat halfway down to the water, the Q-ship pretended to try and escape, so went full speed ahead, turned to port, and brought the enemy right astern. The German maintained a rapid fire, many shots coming unpleasantly across the bridge, one entering the forecastle and wounding two men, of whom one afterwards died. Another shell entered the engineers’ messroom and slightly injured Temporary Engineer Sub-Lieutenant James Purdy, R.N.R. This same shell also cut the leads to the wireless room just above. As several shells fell within a few feet of the ship, Commander Herbert decided to feign surrender, hoisted the International Code pennant close up, turned eight points to port, but with the real intention of firing on the submarine, which had now risen to the surface with complete buoyancy and presented a good target. But in turning to port, _Carrigan Head_ was thus brought broadside on to the swell, so that the ship began to roll heavily and helm had to be altered to get her head on to the sea. At 6.50 p.m. the enemy was about 1,500 yards away, and while both lifeboats were being lowered the submarine kept up an intermittent fire. Three minutes later Commander Herbert decided to reveal the character of his ship and attack; therefore, going full speed ahead, he fired seven rounds, one of which seemed to hit. The submarine was considerably surprised and at once dived, so having arrived near the spot _Carrigan Head_ dropped depth charges. The enemy was not sunk, but she did not reappear, such was her fright, until an hour and a half later when she sank the Norwegian S. S. _Lodsen_ off the Scillies. The enemy’s behaviour was typical: as soon as he was attacked he broke off the engagement and took to flight by submerging, and it was only on the rarest occasions that he was willing to fight, as were the Q-ships, to a finish.
