Re the messgaes Kiel\Konigsberg
Am putting together a 2.1 bugfix to cure that and a few other errors but you can alter the files yourself

C:\Program Files\Ubisoft\SilentHunterIII \data\Cfg and open Flotilla cfg in notepad
Change to look like below specifically the Konigsberg exit date IIRC

Base2_0=765;Königsberg
Date2_0_0=1939
Month2_0_0=7
Date2_0_1=1939
Month2_0_1=8
DeparturePointLong2_0=2446551.000000
DeparturePointLat2_0=6560480.000000
Heading2_0=335.051331
Base2_1=750;Kiel
Date2_1_0=1939
Month2_1_0=9

As to Poland well that was a done deal already

Message from Fdu 31\8\39

Supreme Command of the Navy radioed Atlantic boats as follows in message T.O.O. 1743.
1) Start of hostilities against Poland 0445/1/9.
2) Attitude of Western powers uncertain.
3) No attacks against English etc. forces, except in self defense or by special order.
4) Boats to remain in waiting positions for the present.

The radio station was just an excuse
