Between January 1942 and May 1945, II.Gruppe Jagdgeschwader 1 "Oesau" would have fourteen Gruppenkommandeure (group commanders).
The most famous of these Gruppenkommandeure would be Major Heinrich "Pritzl" Bär. Credited with 220 aerial victories, Bär is the 8th ranking aerial "Ace" of all time, and he would go on to serve as Geschwaderkommodore (wing commander) for all of JG 1. Other notable commanders: Oberleutnant Georg-Peter Eder, who would become a quintuple "Jet Ace", scoring at least 24 victories in a Messerschmitt Me 262 while serving with Kommando Nowotny and JG 7. Oberleutnant Fritz Wegner would later become a Generalleutnant within the post-war Luftwaffe, retiring in 1981.
Despite the notable successes, the losses for the II./JG 1 Kommandeure were high. Six of the fourteen Gruppenkommandeure would be killed during the Second World War: Rohwer, Kijewski, Wikcop, Hoeckner, Segatz and Dähne.
