Look up HMS Starling BadAim and you will see they were more than a match for any U Boat packs. Walker's tactics changed the face of the war against the U Boats. When sailing into battle he used to play "A-Hunting we will go" on a gramophone miked up to the ship's message system!

I just did, and what a boat she was!!! More U-Boats sunk then any other ship in WWII, that is impressive!!! Your father must be/have been proud to serve on such a ship, and I thank him for his service.
