Three nurses talking with the Luftwaffe’s ace “Heinz” Bär (Oskar-Heinrich Bär nicknamed “Heinz”) and another German pilot at Comiso, Sicily, likely Summer 1942. Notice the rudder of the Bär’s airplane, the Messerschmitt Bf-109F WNr-13376, showing, with the number 100 (100th kill), the insignia of the "Ritterkreuz des Eisernen Kreuzes mit Eichenlaub und und Schwertern” (Knight's Cross with Oak Leaves and Swords) awarded precisely for the 100th victory. At the time of the photo “Heinz” Bär, which finished the war with 220 kills (221 or 222 according other sources), were, from 11 May 1942, the leader of the Stab I./JG 77 deployed in Sicily for the air offensive against Malta before the move to Tunisia.

Messerschmitt Bf 110 of the Luftwaffe’s Zerstörergeschwader 26 (ZG 26) "Horst Wessel" in maintenance on a Sicilian airfield. Notice the nose compartment weapons open and, in background, a multi-engine Italian aircraft (S.81?). The aircraft is a Bf 110C/D of the 9. Staffel of the III Gruppe (III./ZG 26). The III./ZG 26, as part of X. Fliegerkorps (10th German Air Corps), was the Bf 110 unit deployed in Sicily. The X. Fliegerkorps order of battle 12 January 1941 specify the III./ZG 26 based at Palermo with 34 Bf 110D-3 on strength, 16 of them completely serviceable. On 22 February 1941 the strength of III./ZG 26, again at Palermo, is increased to 40 Bf 110D-3, full serviceable 31. On 22 March 1941 the 9. Staffel, 15 aircraft, 11 full serviceable, is the only unit of the “Horst Wessel” in Sicily, while the entire III./ZG 26 is already in North Africa. The III./ZG 26, except the 7. Staffel still in North Africa, will return in Sicily, at Trapani, on January 1942 as part of the Luftfotte 2. Victor Sierra
