German intervention over Malta was more a result of the Italian defeats in North Africa than Italian failures to deal with the island. Hitler had little choice other than to rescue his Italian ally or lose the chance of taking the Middle Eastern oilfields in Arabia. The "Deutsche Afrika Korps" (DAK or Africa Corps) under Erwin Rommel was dispatched to secure the Axis front in Africa in February 1941. Operation Colossus signalled a dramatic turn around. The Germans launched Operation Sonnenblume, which reinforced the Italians in North Africa. They then began a counter-offensive and drove the British back into Egypt. But operating overseas in Africa meant most of the supplies to Axis forces would come via the sea. This made Malta a dangerous threat to Axis logistical concerns. In response, the "Oberkommando der Luftwaffe" (OKL or Air Force High Command) sent "Fliegerkorps X" (Flying Corps Ten) to Sicily, which arrived in January 1941, to strike at naval forces in and around Malta, and RAF positions on the island, to ease the passage of supplies.
