Fall Gelb relied on the right flank of the panzer attack being covered by the infantry of the 6th Army.
This army had to cross the Albert Canal, and Eben Emael was defending the bridges.
The whole German timetable was based on this attack.
The Heer would only begin its attack 5 minutes after the gliders had touched down, and the drops in Holland were scheduled to begin 30 minutes after the start of the Eben Emael attack.
What if, for some reason, the German attack fails, or is cancelled.
How fast could the Germans cross the Albert Canal? How would they neutralise the fort?
What does all this mean for the battle of France (and the Low Countries of course)? Does is have no effect? Does it simply slow the Germans down a little?
Does this make an allied victory more likely?
