HMS Pasley (1916)

On commissioning, Pasley joined the Thirteenth Destroyer Flotilla, part of the Grand Fleet.^[5] On 18 August 1916, the German High Seas Fleet launched an attempt to draw out and destroy a section of the British Fleet. The British were aware of the German plan owing to radio intercepts, and the Grand Fleet set out to engage the German force, with the Thirteenth Destroyer Flotilla sailing with the Battlecruiser Force.^[6][7] No engagement between the opposing fleets occurred, but during the return voyage, at about 16:45 on 19 August, the light cruiser Falmouth was torpedoed twice by the German submarine U-66. Pasley, along with sister destroyers Negro and Pelican, was ordered to assist the stricken cruiser. Falmouth, escorted by the three destroyers, limped homeward under her own power, with the escort being reinforced by four more destroyers from the Fourth Destroyer Flotilla at about 23:00, with two tugs arriving from Immingham early on 20 August. The force had almost reached safety when the submarine U-63 hit Falmouth with two more torpedoes. Falmouth eventually sank about 5 miles off Flamborough Head.^[8]

In foul weather on the night of 16 September 1917, whilst escorting a convoy from Aspö Fjord^[9] 100 km (62 mi) north of Bergen, Norway, to Lerwick, Pasley rammed and sank the submarine HMS G9, after G9 fired two torpedoes at her, believing her to be a German U-boat; one torpedo missed, the second failed to explode. Pasley stopped to pick up survivors, but only one member of G9's crew was saved, after Able Seaman Henry Old jumped from the destroyer into the sea to attach a running bowline around him, enabling him to be hauled aboard.

Pasley suffered extensive but not critical damage to her bows, and was able to continue her voyage to Lerwick; she was later repaired and returned to the fleet. At the Court of Inquiry held four days after the incident aboard HMS Indomitable at Scapa, it was decided no blame could be attached to Pasley, concluding "that the process of reasoning which led the captain of HM Submarine G9 to mistake HMS Pasley for a U-boat is, and must remain, unexplained".

Their Lords Commissioners of the Admiralty later directed the captain of Pasley, Commander Charles Gordon Ramsey, to inform the Officer of the Watch at the time of the incident, Midshipman Wallis, that in the opinion of the Court of Inquiry the action taken by him "was the right action to take under the circumstances, and that its result, so deeply to be regretted, is evidence that it was taken with commendable promptness and precision....". Commander Ramsey later rose to the rank of admiral; he retired in 1942, and was appointed aide de camp to King George VI. His portrait by Bassano is held by the National Portrait Gallery, London.^[10]

In November 1917, Pasley transferred to the Fourth Destroyer Flotilla, based at Devonport;^[11][12] she was sold for scrap on 9 May 1921.
