there were a lot problems under the Allies, that help the Nazi
the Belgiums Forts were a extention of the Maginot Line to North

but the belgium Goverment made Budgets cuts in artillery !!!
in Orginal plan the Forts Fort Eben-Emael, Battice, d'Aubin-Neufchâteau and Tancrémont
destroy near key bridges and give each support in case of assault (they artillery fire on next fort !)
but Battice, d'Aubin-Neufchâteau, Tancrémont got low range artillery
also was the Fort Telephon line bury low under ground, easy to find by Wehrmacht and cut
so the Fort had no communications to HQ or another forts.
the main fort Eben-Emael was used by Belgium army as a Boot camp for convicted soldiers !
mainly netherland speaking soldiers under only french speaking Officer (and no Elite soldiers)
wat ended in total chaos as the Wermacht invade Belgium

the Netherlands relied on their neutrality
also was poor Coordination of the British Expeditionary Force and French and Belgium force
also French had no trained crews for Tanks !
and they Generals gave order that French Tanks single attack German tank
if they had gave to order the French Tanks groups attack a singel German tank
things had look very different
Belgium Army had only TEN (10) light Tanks
i think it was better they had never build those Forts
and put the Money in Tank massproduktion at FN Herstal
