Poland don't surrender like this

[zzmzzm]

Because a poland army take a city of Slovakia?

It might be the Slovakia unit.

Did you take Danzig? I once found myself wondering why a shattered Poland hadn't surrendered and found out that my clever invasion plans omitted the physical liberation of Danzig

[Hartmann]

Is the "Freie Stadt" Danzig considered part of Poland in the game? Anyway, I would think it likely that the Polish AI might be scripted to not give in when it has units on enemy territory.

There is a chance that Poland (or any country) may not surrender right away depending upon how many surviving Polish units there still are after you capture the capital. It is typically a very small chance and can vary from game to game for variety.

Hope this helps,

Now Poland Army come into bratislava in 1939 November, Slovakia surrender. Now I besiege it， let's see how long will Poland surrender.

Danzig starts the game as a separate state but once Poland surrenders it will become part of Germany.

Ok, Poland has surrender. German liberate Slovakia, but has lost the corp of Slovakia.
