"There is not a single day when those responsible for Czechoslovakia’s destinies have not to consider the possibility of an assault on the most frivolous excuse with the object, as German military experts in Berlin boast, of wiping out the Czechoslovak defense forces within two or three days."

Seems to me, the Czech and German forces were not quite as mis-matched as this report suggests. In 1938 Hitler's forces still had a long way to go to match the fierce image of military power that Hitler was projecting to the world.

Here’s a link to a comparison of military power in the autumn of 1938. The Germans had the Czechs outnumbered about 2:1, leaving out their Polish and Hungarian allies. Germany itself had their most productive region, Bohemia, almost completely surrounded, and the entire country was surrounded by the allies. No foreign help could arrive.

It seems likely the Czechs could have fought for more than two or three days, perhaps for much longer. But it also seems likely the end result would have been exactly the same.

The Czechs didn’t really know yet that fighting to the death was far preferable to being under Nazi rule.
