Fortress construction schedule, appearance of III Ger Panzer

[Celeborn]

Does anyone know when the various fortresses will appear in Germany? The rulebook talks about the Atlantic Wall fortresses but I could find nothing about the "Ostwall"

And while on the topic of schedule, when/where does the III Germanic Panzer Corps arrive in 1943? Welcome also any clarification of what it entails...the rulebook suggests two SS Mech, an SS infantry and some unspecified number of "support troops"

Many thanks!

PS. I am curious only because there are great quantities of Russians in Poland and it is only May 1943. (yes, I plan on having myself taken out and shot)

Ostwall appears around mid '43, July if memory serves.

SS mechanized korps should arrive around same time (again memory's hazy about the correct date). It's just a single corps though, the units mentioned in the rulebook are merely the sub-units of the corps itself.

However, not enough to save you if Red Army is already rampageing in Poland
