The increasing number of British aircraft on the island, at last, prompted the Italians to employ German Junkers Ju 87 dive bombers to try to destroy the airfields. Finally, in an attempt to overcome the stiff resistance put up by these few aircraft, the Luftwaffe took up base on the Sicilian airfields, only to find that Malta was not an easy target. After numerous attacks on the island over the following months, and the arrival of an extra 23 Hurricanes at the end of April 1941, and a further delivery a month later, the Luftwaffe left Sicily for the Russian Front in June that year.
