"Badsworth" began her career on convoy duty in the North Western Approaches. However, in June 1942 she took up the role of close escort in Convoy Harpoon, aiming to deliver vital supplies to the beleaguered island of Malta. The convoy met fierce attacks from the besieging Italian and German forces with only two out of the initial six merchant ships reaching Malta. Whilst entering the Grand Harbour "Badsworth" struck a mine, sustaining heavy damage. She was towed back for temporary repairs, afterwards leaving the island and heading towards Tyne for further repairs. In November 1942 "Badsworth" rejoined the "Londonderry Escort Force" by escorting a convoy headed to Murmansk. In March 1943 she returned to the Mediterranean for another Malta convoy, striking another mine on 22 April 1943. Towed to Liverpool for repairs, the "Badsworth" was then transferred to the exiled Royal Norwegian Navy under the name HNoMS "Arendal".
