Jagdgeschwader 134 (JG 134) "Horst Wessel" was a Luftwaffe fighter-wing prior to World War II. JG 134 was formed on 4 January 1936 with III. Gruppe in Döberitz. The Geschwader was given the honorific name Horst Wessel on 24 March 1936. II Gruppe was formed on 15 March 1936 in Werl and was followed by the Geschwaderstab and I. Gruppe on 1 April 1936 in Dortmund. It would later become one of the premier Zerstörer wings of the Luftwaffe, as Zerstörergeschwader 26.
On 7 March 1936, Hptm. Oskar Dinort, the Kommandeur of III/JG 134, was tasked with a mission to assist Hitler in the reoccupation of Germany's western border states. At noon on 8 March two Staffeln from the III Gruppe were to circle the cathedral of Köln, and then land at the Köln civil airport. With no resistance or push-back from the allies the Gruppe settled in at the airport with their He 51 fighters.[1]
