HMS Amethyst (F116): Trapped on the Yangtze for One Hundred Days
A Capable Wartime Escort
HMS Amethyst was a Modified Black Swan-class sloop built by Alexander Stephen and Sons at Govan, laid down on 25 March 1942, launched on 7 May 1943, and commissioned on 2 November 1943. Armed with six 4-inch anti-aircraft guns and a dozen 20mm cannon, she was originally designated a sloop with the pennant U16, later modified and redesignated a frigate under the new number F116 after the war. Her wartime complement ran to 192 crew, plus, in the great tradition of Royal Navy ships, one ship's cat.
Amethyst proved a genuinely effective escort during the war, carrying out anti-submarine patrols in the Atlantic. Her finest moment came on 20 February 1945, when she attacked and sank the German submarine U-1276 with depth charges, all 49 of the U-boat's crew lost. The kill carried a particular edge of justice to it: U-1276 had only shortly before sunk the corvette HMS Vervain, at the cost of 60 of her crew. She was also credited for a time with sinking U-482 in January 1945, though the Admiralty later withdrew that credit on postwar reassessment of the evidence.
Trapped on the Yangtze
Amethyst's true claim to lasting fame came four years after the war ended. On 20 April 1949, sailing up the Yangtze River from Shanghai toward Nanjing to relieve the British embassy guard ship, she was fired on by artillery of the Chinese Communist People's Liberation Army, then in the final stages of the Chinese Civil War and crossing the Yangtze in force. The shelling killed and wounded a significant number of her crew, drove her aground, and left her stranded, unable to proceed in either direction, in the middle of a warzone she had no part in creating.
What followed became one of the most dramatic stories in postwar Royal Navy history. Amethyst remained trapped on the river for more than three months, subject to prolonged and difficult negotiations between British and Communist Chinese authorities, while her crew endured cramped conditions, dwindling supplies, and the constant tension of being effectively hostages aboard their own ship. Command eventually passed to Lieutenant Commander John Kerans, who took charge of planning a way out.
The Dash for Freedom
On the night of 30 July 1949, Amethyst made her escape, slipping her cable and running downriver under cover of darkness, using the cover of a passing merchant vessel and her own careful navigation to avoid Communist shore batteries along the way. It was a genuinely nerve-wracking journey through more than a hundred miles of hostile, closely watched river, and when she finally reached open water and signalled the message that would become famous back home, that she was safely away, it was reported as a national good-news story at a time when Britain badly needed one.
The escape made Amethyst, and Kerans, household names, and cemented her place in naval folklore as the ship that had defied a trap most observers had assumed she would never escape.
A Film Role, and a Final Scrapping
Amethyst's fame outlived her active service. In 1957 she was brought out of reserve to play herself in the film Yangtse Incident: The Story of H.M.S. Amethyst, a fitting bit of casting for a ship whose real story needed no embellishment. Since her engines were by then inoperable, her sister ship HMS Magpie stood in for the moving shots. Shortly after filming wrapped, Amethyst was scrapped, her final disposal recorded on 19 January 1957, bringing to a close the career of a ship that had gone from sinking U-boats in the Atlantic to becoming, quite literally, a story that Britain told about itself on screen.
