On 1 April 1942 they sank British submarines P36, and " Pandora". A mine sweeper was also sunk and three other ships damaged. On 9 April the destroyers "Gallant" and "Lance" were sunk. Two days later "Kingston" was severely damaged. The cost of these operations, to 13 May, was 17 Ju 87s, four on 10 May alone. The majority of the losses were in combat with RAF fighters. Over 21–24 May the group replaced the losses and moved to Derna, Libya. The successes against British naval units cost it half of its pre-operation strength. The group carried a last bombing raid on 13 May against RAF Hal Far.
