, the German auxiliary submarine chaser UJ-2213/Heureux, the Italian auxiliary minesweepers No. 61/ Costante Neri, V 131/Amgiola Maria C. and No. 164/ Rosa Madre, and the German escort vessel SG-10/Felix Henri. The former fruit transport ship Felix Henri had been modified into an auxiliary cruiser by the French in 1940. She was captured by German troops on 14 December 1942 in Marseilles, modified into the fast escort vessel SG-10, commissioned on 1 May 1943 and attached to the 3rd escort flotilla. Sickle also sank ten sailing vessels and the German merchant Reaumur. Sickle also attacked and damaged the Italian merchants Oriani and Giovanni Boccaccio. The Giovanni Boccaccio was later beached to prevent her from sinking. The Italian merchant Mauro Croce, the German submarine U-755, the German auxiliary submarine chaser UJ 2210 and the German transport Lola were also attacked, but unsuccessfully.

 on 31 May 1944. She was in action on 4 June when she fired upon shipping in Mitylene Harbour and later engaged in a gun battle with two German patrol vessels. During the fight, one member of the crew was washed overboard and taken prisoner. Sickle escaped the engagement and continued on her patrol. On 12 June she spotted a convoy in the approach to Steno Pass. The convoy suspected the presence of a submarine and dropped two depth charges. Shortly after this, contact with Sickle was lost, and it is thought that she had probably struck a mine in the Kythera Channel.
