Gruppe Kdr's KG53 8.40

[steve sheridan]

Hi, im trying to tabulate the Order of Battle for KG53 13.8.40

Looking at a number of sources, there appears to be a descrepancy with II/ KG53. I have the following:

Mjr Fritz Winkler Grp Kdr, listed on various sites on the net and listed in Francis K Mason's Battle of Britain book, until replaced by a Mjr Max Gruber who in turn was captured on 15.9.40
I also have seen an ObstLt Kohlbach in charge of II/KG53 during this period!

My information leads me to think that Mjr Reinhold Tamm was the Grp Kdr
until his demise on the 18.8.40.
According to Michael Holm's site, and the Chronik of KG53 by Heinz Kiehl,
Tamm wasn't replaced until 18.9.40 as Grp Kdr by Mjr Hans Steinweg.
Could it be Winkler replaced Tamm, and also Gruber until he was captured 3 days before Steinweg's appointment??

Also there is uncertainty over the III/KG53 Kommandeur!
various sources claim Mjr Friedrich Edler von Braun was c/o of III/KG53,
again Mason's work states this, where as i believe the correct Kdr was
Mjr Willi Rohrbacher!!

Can anybody confirm these positions, as every publication i look at there
is varying information.

Best regs,
Steve.
