10 May Battle of France. The Germans invaded the Netherlands and Belgium (bypassing the Maginot Line). Britain and France moved to counter this attack.

German bombers hit air bases in France, Luxembourg, Belgium, and the Netherlands, destroying large numbers of Allied planes on the ground and crippling Allied air defenses After months of nervous speculation, Germany brought war to western Europe on May 10, 1940, with the primary goal of conquering France

On the ground, German forces advanced in two directions: 1.Through the Netherlands and northern Belgium (where Britain and France had expected) 2.The larger force to the south, through Luxembourg and into the Ardennes Forest on a path that led directly into the French heartland Unaware of the German advance to the south, Britain and France sent the bulk of their troops to Belgium. Elite squads of German paratroopers were dropped onto fortified Allied points along the front, neutralizing a key element of France’s defense strategy
