Meanwhile the submarine had approached to within 400 yards, being obscured by the _Dunraven's_ smoke; and, for this reason, though every moment's delay added to the risk of her after magazine's being blown up, Captain Campbell decided not to open fire until he could get a clearer view of his enemy. Unfortunately, before this happened, a heavy explosion revealed to the submarine the true nature of thee _Dunraven_ by accidentally starting her fire-gongs, one of her guns, with its gun crew, having been destroyed. There was no alternative, therefore, but to drop the screens--though only one gun could be brought to bear--the enemy submarine, taking alarm, having already begun to submerge. It was now obvious that the _Dunraven_ would be torpedoed, and Captain Campbell took prompt measures. Removing the wounded, and concealing them in cabins, and bringing a hose to bear on the fire, he signalled that all traffic should be kept below the horizon during the final {206} act that was to come. Having been twice torpedoed, he then sent away a second "panic" party, and thus left the ship apparently forsaken, with all her guns unmasked and the White Ensign flying. The fires had now to be left to work their will; ammunition was exploding on all sides; and, for fifty minutes, while Captain Campbell and those remaining with him still lay hidden, the submarine cautiously surveyed the vessel through her projecting periscope. She then came to the surface, astern of the _Dunraven_, where no guns could be trained on her, and, for twenty minutes, proceeded to shell her before steaming past, and again examining her. Captain Campbell then decided to let off a torpedo at her, but this just missed. Apparently unobservant of this, the submarine then turned and steamed slowly down the other side, Captain Campbell loosing a second torpedo, also unhappily without result. This was seen by the enemy, who at once submerged again, Captain Campbell signalling for help; while, as a last resource, he disembarked yet a third "panic" party, leaving but one gun's crew aboard. Nothing more was heard from the enemy, however, and, in a few minutes, British and American destroyers were on the scene; the wounded were transferred; the fires were put out; and the _Dunraven_ was taken in tow. Both Captain Campbell and Lieutenant-Commander Sanders received the Victoria Cross for their _Q_ boat work--the latter being unfortunately lost, with his schooner the _Prize_ a few months after the incident just related.
