They used U-boats
From what I know, they used the Blitzkrieg technique. (Possibly Incorrect)
They wanted to defeat the British and French before American troops could be used.
It was a tactical defeat but a strategic success, because allowed about 400,000 British and French soldier of being evacuated to England, thus preventing them of being captured by the Germans.
The outcome was the liberation of many French villages and the defeat of the Germans in that area and capture of many Germans. They went on to conquer the Germans in the rest of France, Belgium and Germany. Russia mounted an invasion in the Eastern European nations too.
No.
According to the findings of a diary the defeat of the Germans was brought on by when Hitler decided to take his men out by fear of losing them.
Because the Germans invaded them.

The French were focused on the French-German border, meanwhile, the Germans entered France through Belgium. The Germans were able to quickly flank the French forces, and kept the French pinned until they retreated to England.
it was the first defeat for the germans
Because. That is the right answer.
For four years, yes. Read the history. Yeah, they surrendered very quickly and easily to the Germans. This meant that they gave up contol of their government and Germans picked pro-NAZI French (who were allies of the NAZIs) or French-speaking Germans to fill all the positions in the French government. The French people were told to obey this new Vichy government, and most of them did (but not all). The advantage to the French is that their cities were not all blown to bits, which would have happened if they put up a strong fight against the Germans.
