From left to right: Maresciallo d'Italia Ugo Cavallero (chief of the Italian High Command), Generalmajor Alfred Gause (Chef des Generalstabes Panzerarmee "Afrika"), and Generalfeldmarschall Erwin Rommel (Oberbefehlshaber Panzerarmee "Afrika"). No information about date or place, but surely in North Africa after June 1942. Cavallero had a rather conflicting relationship with Rommel, whose advance into Egypt after his success at the Battle of Gazala he opposed, advocating instead the planned invasion of Malta; his opinion, shared by Kesselring and Rintelen, was however discounted by Hitler and Mussolini.
