HMS Black Swan (U57): She Gave Her Name to a Class, and Tried to Rescue the Amethyst

The Ship That Named Her Class

HMS Black Swan was laid down by Yarrow Shipbuilders on 20 June 1938, launched on 7 July 1939, and commissioned on 27 January 1940, the name ship of the entire Black Swan class of sloops, one of the most successful anti-submarine escort designs of the war. She carried six 4-inch anti-aircraft guns alongside pom-poms, machine guns, and by war's end up to 110 depth charges, a genuinely formidable submarine hunter for her size.

Bombed, Mined, and Still Fighting

HMS Black Swan's early war service included convoy escort along Britain's east coast and operations during the 1940 Norwegian Campaign, during which she suffered bomb damage on 27 April 1940 and mine damage that November, absorbing a genuinely punishing start to her career. From 1941 she escorted convoys in the Irish Sea and the Mediterranean, and her most significant single action came on 2 April 1943, when, escorting Convoy OS 45 from Liverpool to Freetown, HMS Black Swan and the corvette HMS Stonecrop sank U-124, one of the top-scoring German U-boats of the entire war, a genuinely major kill against one of the most successful and dangerous submarines the Kriegsmarine ever put to sea.

Under Fire on the Yangtze

HMS Black Swan went on to serve in the Far East and Pacific theatres against Japan, and her postwar career brought her into one of the most dramatic diplomatic and military incidents of the immediate Cold War era: the 1949 Yangtze Incident, when the frigate HMS Amethyst became trapped under fire from Communist Chinese forces on the Yangtze River. HMS Black Swan was among the ships that attempted to reach and relieve Amethyst, and came under fire herself in the process, suffering twelve wounded and severe damage to her superstructure, a genuinely dangerous episode that unfolded amid the chaos of the closing stages of the Chinese Civil War and drew international attention to the plight of British ships caught up in it.

A Final Tour Off Korea

HMS Black Swan went on to serve during the Korean War, adding yet another conflict to a service record that already spanned the Second World War and one of the most tense confrontations of the early Cold War. She was finally scrapped in 1956 at Troon in Scotland, closing out the career of a ship that had lent her name to an entire successful class and, in her own right, survived bombs, mines, a major U-boat kill and gunfire on the Yangtze.
