Maginot line ruled, tad outdated but could do it's job very well.
Politics made it worthless with the open gap of Belgium. Why the Belgians didn't co-op with them and also made a wall and why the Dutch didn't think 'Oh shit then they'll get us too' and also made one. I don't know.. Political incorrect I guess.
Our fortresses where not build for WW2. We all made mistakes. First of all, The Belgian goverment gave the order to a german company to build Eben Emaul. So ye, Germany knew everything about the fortress.
If the Fortresses did their job, they would have severly slowed down the germans. If the Maginot line stretched towards Belgium, and we Belgians did the same, it would have been far difficult for the germans.
The germans where very lucky aswel. Just as we attempt to blow up the Vital bridges, they knock out our cannon. When we sended 8 Fairy battle's to destroy the bridge, the germans JUST had aircover and AA fire.
We Lower countries dint do bad though. We Belgians lacked tanks. The Dutch, while very well motivated, dint had much equipment at all. And the French army dint had good communication and Tactics.
Still, we won the war in the end.Thats all that matters
