The Phony War- WTH?!

Yes, I included the BEF and Belgian army, since they were supposed to operate together.

And my count, from your link, is 72 divisions on the Belgian border vs 29+10=39 along the Maginot line, which is much of the border, so it’s a vastly higher concentration of troops.

Too late to edit : ETA : don’t have time to check what the discrepancy is right now.
