Hello,
On 18 March 1917 Jasta 6 was still assigned to german 2. Armee and was stationed on the aerodrome Ugny-l'Equipée, ca 8 km N of Ham. The next day Jasta 6 had to change the aerodrome because of the beginning of the german retreat to the "Hindenburg Line", some 30 km to the east (Siegfried-Stellung).
In most of the well known publications it is said that Jasta 6 moved on 19 March 1917 from the aerodrome Ugny-l'Equipée within german 2.Armee to the german 4. Armee on 20 Mar 1917 and was stationed at the aerodrome Aulnoye.
But the only Aulnoye I could find on the map is located 28 km SE of Valenciennes within german 1. Armee area and ( at least I think so...) too far away from the front lines. On the other hand all the Jasta 6 claims between the end of March 1917 and the end of May 1917 were claimed in the area around St.Quentin - Cambrai (within german 1. and 2 Armeen) but obviously not within german 4.Armee in Flanders

So can anyone tell me the exact location and the propper assignement of Jasta 6 between 20 March 1917 - 9 June 1917?
Immo
