BOB a mistake ? --- The Battle of France

[Bobb4]

The reason why France was lost is simple.
1) The French army failed to used its tanks units correctly.
2) No attempt was made to slow the German's down, especially in Paris. Look how the Russians took it, fighting in every street of every city till the last.
3) The French allowed most of it's airforce to be destroyed on the ground.

So did the British withdrawing cause the collapse, the answer is no, the collapse begand in the Ardenne Forrest. French troops spent their time falling back to form a line of defence.
As they fell back the troops on the ground developed the retreat mentality which is devastating to an army unless properly explained and can easily turn into a rout.

A similair example can be seen with the staged withdrawal of ARVN forces in Vietnam in 1975.
The ARVN generals wanted to group their forces to stage a massive counter attack.
But all the troops on the ground knew was they were withdrawing, retreating...
This led to the total collapse of a superior army in both numbers and firepower.
The fault being poor communication.
The same goes for why France was lost.
