HMS Boreas (H77)
Résumé
HMS Boreas was a destroyer built for the Royal Navy around 1930. Initially assigned to the Mediterranean Fleet, she was transferred to the Home Fleet in 1936. She then patrolled Spanish waters, enforcing the arms blockade during the first year of the Spanish Civil War of 1936–1939. She spent most of World War II on convoy escort duties in the English Channel and the North Atlantic, based at Dover, Gibraltar, and Freetown, Sierra Leone. Boreas also participated in Operation Husky and was later loaned to the Royal Hellenic Navy the next year after conversion into an escort destroyer. She was renamed Salamis and served in the Aegean for the rest of the war. Salamis became a training ship after the war until she was returned to Britain and scrapped in 1952.

For anti-aircraft (AA) defence, Boreas had two QF 2-pounder Mk II single-mounted AA guns on a platform between her funnels. She was fitted with two above-water quadruple torpedo tube mounts for torpedoes. One depth charge rail and two throwers were fitted; 20 depth charges were originally carried, but this increased to 35 shortly after World War II began in September 1939. The ship was fitted with a Type 119 ASDIC set to detect submarines through sound waves beamed into the water that would reflect off the submarine.
