60 years ago this morning on 31st July 1949, HMS AMETHYST sent this signal after her dramatic journey down the Yangtse River following the attack and subsequent detention by Communist Chinese forces in April.
AMETHYST was completed by Alexander Stephen's Linthouse yard in Glasgow in 1943. She had a good war service and was present at the formal U- boat and Japanese surrenders.
She also served during the Korean War before she went into reserve and relived her Yangtse Incident in the film of the same name before going to breakers at Devonport in 1957.
The current Navy News has a special supplement with cutaway drawing of her.
Her full signal read "Have rejoined the Fleet South of Woosung. No damage or casualties.God save the King."
This old picture shows her in the immediate period after the breakout.
