HMS Pasley was an Admiralty M-class destroyer built on the Tyne by Swan Hunter & Wigham Richardson for the Royal Navy and launched on 15 April 1916.

The ships carried a maximum of 237 long tons (241 t) of fuel oil that gave them a range of 2,100 nautical miles (3,900 km; 2,400 mi) at 15 knots (28 km/h; 17 mph).

[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 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.

Commander Ramsey later rose to the rank of admiral; he retired in 1942, and was appointed aide de camp to King George VI.
