Germans ONLY "Little Saturn" No Russians Pls

[Glider]

For the attention of Ratzki:
We are going to fight the battle till the last turn?or
we ll stop it little bit earlier to mantain the FOW?
Currently at the North Battle we are at turn 21 and as we have a good turn rate i think that in a couple of days will reach to the end.

I have been looking for instructions on how to finish the battle and preserve the FOW, I am sure it is here somewhere but I couldn't find it, only the post above. How do we proceed with the last few turns?
