Kageneck claimed his last two aerila victories against British Commonwealth fighters on 12 December. That day, he claimed a Hurricane and Curtiss P-40 Warhawk fighter shot down near Timimi. On 24 December, Kageneck was seriously wounded in combat with several Desert Air Force (DAF) P-40 and Hurricane fighters south of Agedabia. Both Sergeant Maxwell of No. 94 Squadron and Pilot Officer Thompson No. 229 Squadron made claims for a fighter shot down in the same action. Many years later, some sources, including Kageneck's brother, August von Kageneck, claimed that the shots which hit Erbo were fired by the pre-eminent Australian ace of the war, Clive Caldwell. The main reason for this was that Caldwell favoured attacks from beneath his opponents, which was precisely the fashion in which Kageneck's wounds were sustained.
