 As "Pargust" approached the U-boat’s position "UC 29" fired a torpedo which hit "Pargust" in the engine room.Campbell made no attempt to avoid this, as he was convinced the only way to allay the suspicions of a U-boat was to allow his ship to be torpedoed, relying on her buoyant cargo to keep her afloat, and obliging the U-boat to surface to finish her off with gun-fire at which point it would be vulnerable to his guns.He had already employed this strategy with "Farnborough", and would do so again, in one of the epic Q-ship actions, with "Dunraven".
