They were about to fail their invasion in France, The only tank brigade France had push them back because the P3 was too weak compare to French tanks, it could barely pierce the armor.
What make them finally won: of course, competent Head of Army than French ones (not difficult at this time), Tank radio on every tank (only the tank battalion leader had a radio on French side) and Stukas. Germamy won the early war with a better airforce (well French airforce was barely inexistent, it goes in peer with the HQ level of competency) and lost it when they lost they're air superiority.
France army could also have retreat over the Seine and hold here, but they decided to surrender...
You and Braicharados are correct about the superiority of French and British tanks in a head on armour clash (rather than the fast moving armour group tactic the Germans were exploiting). Luckily there was a line of 88mm guns in the French's way which the Germans found vaporised the 'superior' French tanks. Then you say the superior German tank communications and superior leadership backed by a well trained air-force with their superior aircraft swung it with the help of poor French morale and leadership
You make it sound like the German army was better than everyone else in most respects.
I am a little more hazy on the French surrender but know that Rommel and Guderain had gone through the French lines like butter, and were rampaging across France at an astonishing speed (200 miles on one day)
I don't really want to argue or derail the thread I would simply say that anyone who like Bracharadas who tells people that they should learn their history (though he has many excellent points) is playing with fire on these forums - there is a lot of knowledge and no-ones is complete plus there can be differing opinions on its interpretation.
