In case the above update was a bit dull: in OTL, by may 13 the germans were crossing the Meuse in Sedan, and the german panzers arrived to the sea in May 21, trapping the allied armies and winning the campaign for Germany. This is hailed as the first ever blitzkrieg. In TTL, the german change of plans and the presence of reinforcements in Sedan mean that by the end of May, the germans have not been able to cross the Meuse. which means that the Battle of France, instead of the lighting campaign that astonished the world, is becoming a sluggish positions battle. The germans will win it in the end, but not until after the allies have bled them white.
