Zerstörergeschwader 1 (ZG 1—1st Destroyer Wing) (lit. destroyer wing) was a Luftwaffe heavy/destroyer Fighter Aircraft-wing of World War II. Formation Zerstörergeschwader 1 (ZG 1—1st Destroyer Wing) was formed with two Gruppen (groups) before the war. Initially, no Geschwaderstab (headquarters unit) nor III. Gruppe (3rd group) was formed. I. Gruppe (1st group) was formed by renaming II(s). Gruppe (2nd group) of Jagdgeschwader 132 "Richthofen" (JG 132—132nd Fighter Wing) to I. Gruppe of Zerstörergeschwader 141 (ZG 141—141st Destroyer Wing) on 1 November 1938 flying the Messerschmitt Bf 109 single engine fighter. On 1 May 1939, I. Gruppe of ZG 141 became I. Gruppe of ZG 1. During this entire time, the Gruppe was commanded by Major Joachim-Friedrich Huth. This unit was initially based at Jüterbog-Damm until it was moved to Mackfitz, present-day Makowice in north-western Poland, on 24 August 1939. The II. Gruppe was formed on 15 May 1939 at Fürstenwalde and was also equipped with the Bf 109. The Gruppe had originally been formed as II(l). Gruppe of Jagdgeschwader 135 (JG 135—135th Fighter Wing). It was then renamed to I. Gruppe of Jagdgeschwader 333 (JG 333—333th Fighter Wing) on 1 November 1938 which was then briefly given the designation I. Gruppe of Jagdgeschwader 54 (JG 54—54th Fighter Wing) on 1 May 1939. During this creation process, the Gruppe was cammanded by Major Rudolf Stoltenhoff, who turned over command to Major Hellmut Reichard on 15 May 1939. World War II Invasion of Poland and Phoney War On the outbreak of World War II the unit was based with 1. Fliegerdivision in Central Germany. During the German invasion of Poland ZG 1 was part of Luftflotte 3. Only the I. Gruppe was fit for action at Mühlen Eichsen. The group operated the Bf 110 C. The division and air fleet supported the 4th army on most northern part of the line as it advanced to capture Danzig and Bydgoszcz. Only three of the ten Zerstörergruppen were genuine units (I./ZG 1, I./ZG 76, I(Z)./LG 1). The rest were given Bf 109s and nominated Jagdgruppen (for example II./ZG 1 was renamed II./JGr 101). Among the operational Bf 110 units there were barely 100 aircraft available. Little is known of I./ZG 1's activities other than the fact that they were the least successful of all the fighter units in Poland. In one long-range fighter escort mission I./ZG 1 claimed two Polish fighters but lost Hauptmann von
