This from my JGr. 200 research:
Further north, II. Jagdkorps told JG 27 that the four JGr. 200 men who had arrived with the Geschwader the day before should instead report to II./JG 2 at "Airfield 409" (this was probably Baron, 18 km. south east of Creil, where that Gruppe was based).
The 18 km distance (a little different from Snautzer's) was a measurement taken with the line tool on Google Earth.
