On 25 December 1940, whilst part of the escort to convoy WS-5A, a troop convoy to the Middle East, Berwick was in a surface engagement with the German heavy cruiser Admiral Hipper about 700 nautical miles west of Cape Finisterre, Spain 43°39'N, 25°08'W.
Despite being thoroughly ready for combat Berwick got the worst of the encounter.
During a 35 Minute engagement she scored no hits on Admiral Hipper, and sustained a fair amount of damage, being hit by several 8-inch (which for the most part passed right through the ship) and 4.1-inch shells.
The action did however, drive off Admiral Hipper, and saved the convoy from any losses. Four of her complement a Royal Marines gun crew were killed and she had to return to Britain for repairs, which lasted until June 1941
