The French began mobilization on 24 August 39.

The French did attack Germany with in the first week (4 days). They met light resistance at first. Then they came to the Siegfried line, where the offensive was halted with loss of armor and men, while they were few, this still caused the French to retreat back to France.

The Siegfried line was not just trenches and barricades in 39. There were bunkers, gun positions, minefields, and tank traps.

Are you trying to say that the Czechs had more artillery pieces than the Germans?

The French had 100+ divisions mobilized by week two. The Poles were lied to and left to their own devices.

I also believe that it would have been an interesting battle in 38, Germany new how to use what mobile forces it had, and as you state the Czechs were well trained. How their doctrine would match against the German would be interesting. We also have to assume that Germany would have pushed for war if Czechoslovakia had with stood, Germany could have just moved on and waited till 39.
