June 26, 1917

In a concentration of German airpower, the first Jagdgeschwader (fighter wing) is formed. With suitable transportation and tents for aircraft, the Jagdgeschwader concept is a flexible combat organization with four squadrons that is able to quickly relocate along the front as required. JG 1 is commanded by Major (Capt.) Manfred von Richthofen. Three more Jagdgeschwaders – which would be nicknamed “flying circuses” – are formed before the Armistice.
