Before Pargust could be ready for sea again much would have to be done to her at Devonport, so Captain Campbell proceeded to look for a new ship, and this was found in the collier Dunraven. She was fitted out at Devonport under his supervision, just like her predecessor, and her crew turned over en bloc from Pargust. She was commissioned on July 28, and within a fortnight Captain Campbell, now already promoted to post-captain at an age which must certainly be a record, was engaged in the most heroic Q-ship fight of all the long series of duels only a few days after leaving Devonport.

Just before eleven on the forenoon of August 8 Dunraven was in the Bay of Biscay, about 130 miles west of Ushant, doing her 8 knots and disguised as a defensively armed British merchantman, for which reason she had a small gun aft. In order to conform further with merchant-ship practice of this time, she was keeping a zigzag course. On the horizon appeared a submarine, about two points forward of Dunraven’s starboard beam. The German was waiting, you see, in a likely position for catching homeward-bound steamers making for the western British ports, and on sighting this ‘tramp’ he must have felt pretty sure she was bringing home a cargo of commodities useful for winning the war. Pursuing the more cautious tactics of the time, the enemy, having apparently ascertained the ‘tramp’s’ speed and mean course, submerged, but at 11.43 she broke surface 5,000 yards off the starboard quarter and opened fire. In order to maintain the bluff, Captain Campbell replied with his defensive gun, made as much smoke as possible, reduced to 7 knots, and made an occasional zigzag in order to give the enemy a chance of closing. Dunraven was now steaming head to sea, and the enemy’s shots were falling over, but after about half an hour of this the submarine ceased firing, came on at full speed, and a quarter of an hour later turned broadside on, and reopened fire.

In the meantime the decoy was intentionally firing short, and sent wireless signals en clair so that the enemy could still further be deceived. Such messages as ‘Submarine chasing and shelling me,’ ‘Submarine overtaking me, help, come quickly ... am abandoning ship,’ were flashed forth just as were sent almost daily by stricken ships in those strenuous days. Dunraven’s next bluff was to pretend his engines had been hit; so Captain Campbell stopped his ship, which now made a cloud of steam. The next step was to ‘abandon ship,’ and the ‘tramp’ had enough way on to allow of her being turned broadside on and let the enemy see that the vessel was being abandoned. Then, to simulate real panic, one of the boats was let go by the foremost fall, an incident that somehow seems to happen in every disaster to steamers. Thus, so far, everything had been carried out just as a submarine would have expected a genuine ‘tramp’ to behave. Not a thing had been omitted which ought to have been seen by the enemy, who had already closed and continued his shelling. From now ensued a most trying time. To receive punishment with serene stoicism, to be hit and not reply, is the supreme test; but these officers and men were no novices in the Q-ship art, and none had had greater or more bitter experience. However, not all the tactics and devices could prevent the enemy’s shells hitting if the German insisted, and this had to be endured in order that at length the submarine might be tempted inside the desired range and bearing.

Thus it happened that one shell penetrated Dunraven’s poop, exploding a depth charge and blowing Lieutenant C. G. Bonner, D.S.C., R.N.R., out of his control position. This was rather bad luck, and two more shells followed, the poop became on fire, dense clouds of black smoke issued forth, and the situation was perilous; for in the poop were the magazine and depth charges, and it was obvious that as the fire increased an explosion of some magnitude must soon occur. But the main consideration was to sink the submarine, and it mattered little if the Q-ship were lost; so Captain Campbell decided to wait until the submarine got in a suitable position. It was exactly two hours to the minute since the submarine had been first sighted when, just as he was passing close to Dunraven’s stern, a terrific explosion took place in the poop, caused probably by a couple of depth charges and some cordite. The result was that the 4-inch gun and the whole of its crew were blown up into the air, the gun vaulting the bridge and alighting on the well deck forward, while the crew came down in various places, one man falling into the water, and 4-inch projectiles being blown about the ship in the most unpleasant manner.

“Dunraven” Doomed
This picture shows the Q-ship in her last hours. She has been through an historic duel, she has been torpedoed and shelled, her poop has been blown up, and the Atlantic seas are breaking over her deck.
