Career

Wartime

Upstart spent most of her wartime career operating off the south coast of France, where she sank the French fishing vessels Grotte de Bethlehem and Torpille, the German auxiliary minelayer Niedersachsen (the former French Guyane) and the German merchant Tolentino (the former French Saumur). She also launched failed attacks against the French merchant Medjerda and the Italian merchant Pascoli.

Greek service
For other ships with the same name, see Greek submarine Amfitriti.

Upstart survived the war and was loaned to the Greek Navy in 1945, where she was renamed Amfitriti. She served with the Greek Navy for seven years, and was returned to the Royal Navy in 1952. She was subsequently sunk as an ASDIC target off the Isle of Wight on 29 July 1959.
