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.
