During the Second World War she participated in several distant escort missions of important convoys, and in some of the major surface actions in the Mediterranean, e.g. Punta Stilo, Cape Teulada (Spartivento), Cape Matapan and Operation Pedestal. During the latter, on 13 August 1942, she is torpedoed and severely damaged by submarine HMS Unbroken, but manages to stay afloat. She is towed back to Naples, and then to La Spezia, where the armistice in September 1943 stops repair work on her, due to fears that the Germans may use her as block ship to prevent entry into the harbour of La Spezia. On 22 June 1944 she is attacked by Italian frogmen of the Free Italian forces, riding British mini-subs, and sunk. When Allied forces enter La Spezia in April 1945 she is found capsized and sunk at her moorings. She is recovered and then immediately broken up.
