Adam,
Does Obstlt.Aue preceed Beckmann as Gr Kdr, or is Beckmann incorrect?
Holm gives Beckmann as Gr Kdr from Nov 1939.
de Zeng/Stankey in their Careers Summaries give this for Beckmann's early career
"BECKMANN, Theodor. (DOB: 24.09.97 in Everswinkel/Westfalen). (R, DKG). 10.11.39 Maj., trf
from LKS 2 Berlin-Gatow to KG 3 for instruction as a Verbandsführer. 27.11.39 trf to
Stab/KGr.z.b.V. 10 Burg as Kdr. 01.04.40 Hptm., appt Kdr. IV./KG.z.b.V. 1 (to 12.42)."
Just curious....
