This action was perhaps the finest feat amongst the very many gallant deeds performed by decoy ships during the war. It displayed to the full the qualities of grim determination, gallantry, patience and resource, the splendid training and high standard of discipline, which were necessary to success in this form of warfare. Lieutenant Charles G. Bonner, R.N.R., and Petty-Officer Ernest Pitcher, R.N., were awarded the V.C. for their services in this action, and many medals for conspicuous gallantry were also given to the splendid ship's company.
Captain Campbell, as will be readily realized, met with great success in his work, and he was the first to acknowledge how this success was due to those who worked so magnificently under his command, and he also realized the magnitude of the work performed by other decoy ships in all areas, since he knew better than most people the difficulties of enticing a submarine to her doom.
On September 17, 1917, in position Lat. 49.42 N., Long. 13.18 W., the decoy ship Stonecrop, a small steamer commanded by Commander M. Blackwood, R.N., armed with one 4-inch, one 6-pounder gun and some stick-bomb throwers and carrying four torpedo tubes, sighted a submarine, which opened fire on her at long range, the fire being returned by the 6-pounder mounted aft. After the shelling had continued for some time the usual order was given to "abandon ship," and a little later the periscope of the submarine was sighted some distance away. The submarine gradually closed, keeping submerged, until within about a quarter of a mile, when she passed slowly round the ship, and finally came to the surface at a distance of about 500 yards on the starboard quarter. She did not close nearer, so the order was given to open fire, and hitting started after the third round had been fired and continued until the submarine sank stern first. No survivors were picked up, but all the indications pointed to the certainty of the destruction of the submarine.
PATROL GUNBOATS
Mention may here be made of another vessel of a special class designed in 1917. In the early summer, in consequence of the shortage of destroyers, of the delays in the production of new ones, and the great need for more small craft suitable for escorting merchant ships through the submarine zone, arrangements were made to build a larger and faster class of trawler which would be suitable for convoy work under favourable conditions, and which to a certain extent would take the place of destroyers. Trawlers could be built with much greater rapidity than destroyers, and trawler builders who could not build destroyers could be employed for the work, thus supplementing the activities of the yards which could turn out the bigger craft.
Accordingly a 13-knot trawler was designed, and a large number ordered. Great delays occurred, however, in their construction, as in that of all other classes of vessel owing to the pressure of various kinds of war work and other causes, and only one was delivered during 1917 instead of the twenty or so which had been promised, whilst I believe that by July, 1918, not more than fourteen had been completed instead of the anticipated number of forty. I was informed that they proved to be a most useful type of vessel for the slower convoys, were excellent sea boats, with a large radius of action, were a great relief to the destroyers, and even to light cruisers, for convoy work. It is understood that some fifty were completed by the end of the war.
NET PROTECTION FOR MERCHANT SHIPS
This idea originated in 1915 or 1916 with Captain Edward C. Villiers, of the Actaeon Torpedo School ship. Experiments were carried out by a battleship at Rosyth, in the first instance, and later at Scapa. They were at that time unsuccessful.
At the end of 1916 I gave directions for a reconsideration of the matter, and fresh trials were made; but early in 1917 there seemed to be no prospect of success, and the trials were again abandoned. However, Captain Villiers displayed great confidence in the idea, and he introduced modifications, with the result that later in the year 1917 directions were given for fresh trials to be undertaken. At the end of the year success was first obtained, and this was confirmed early in 1918, and the device finally adopted. A curious experience during the trials was that the vessel carrying them out was actually fired at by a German submarine, with the result that the net protection saved the ship from being torpedoed. It is not often that an inventor receives such a good advertisement.
