Hello
According to official German sources a decision was taken during the summer of 1918 to form BG 9 by
splitting up BG 3...however this was
not done before the EOW because of the War situation..
As for Hildebrandts books which now are available on the net, they basically have
very good information regarding those flyers who served within the German Air Force during the Great War. But in some cases they have wrong information, probably because the information was "collected" during WW2 or after that...
For Fiebig the information are rather vague but he could not have been commander of a unit which never existed..

... However he could have been "nominated" for that job...
I actually have him being the commander of BG 3 at the end of the War....
