Regarding this, why did Germany attack the Netherlands?
The Germans wanted to secure their borders and northern flank. They wanted to make Europe into a closed fortress. That is why the Allied forces were unable to attack Germany from the air or over land. The Germans wanted to use the Dutch airfields to bomb France and England and to support their own troops.
Also, why did Germany invade France? When the Germans attack came through the Ardennes, they caught the French and their British allies by surprise because the French believed it was impassable to tanks. Having successfully made their way into France, German forces then employed a tactic known as the 'sickle stroke'.
In this regard, why did Germany invade the Low Countries?
The Germans decided to invade France through the Low Countries (this operation was called Fall Gelb by the Germans) in order to avoid the heavily fortified Maginot Line along the French-German border. Luxembourg fell first, with the Netherlands surrendering on May 14 after the devastating German bombing of Rotterdam.
Why did Germany invade Luxembourg?
