AWARDS FOR MINESWEEPING
DSC: Distinguished Service Cross. DSM: Distinguished Service Medal. MID: Mention in Despatches.

British Yard Mine Sweeper
BRITISH YARD MINE SWEEPERS
BYMS’s were built in the United States and transferred the Royal Navy under the Lend-lease Programme. “British Yard Mine Sweepers” are so called because they were built to the same design as the US Navy’s “Yard Mine Sweepers”.
Crews for the BYMS’s would sail to the United States, often on the Queen Mary, which could sail unescorted because of her greater speed, to collect their vessel. They would then have the formidable task of sailing their small vessel back across the Atlantic Ocean, often in winter.
26 August 1943 the USA Cargo ship John Bell was sunk by a torpedo from German submarine U-410, in the Mediterranean off La Calle, Algeria with the loss of one of her 72 crew. Survivors were rescued by BYMS 2023.
