| Operation Yellow and Weimar |
The German Army that was going to carry out Operation Yellow was much better equipped than the Allied Forces. The Allies thought that the German Army would simply march through the flatlands of Belgium to attack France. The Allies prepared by moving their army to an area where the second the Germans violated the Belgian neutrality, they could strike back. Germany had a better plan and was going to move through the Low-Lands of Belgium and meet the Allied Army at the point where Belgium, Germany, and France meet.
On May 10, the Germans moved into the West to battle. Luxembourg put up no resistance and Holland's armies fell in a day. Both governments fled to London. On May 13, the Germans where able to break through the Maginot Line. The border that had so much fortification against the Germans on the France/Germany border did not stretch all the way to the Belgium/France border.
The British and French Armies marched north into Belgium, right into a German trap. Once the Germans broke through, there was nothing to stop them from heading straight towards the British Channel. Germany took full advantage of this. They marched straight up with very little to stop them. On May 20, the German force reached the channel, isolating the Allied army in Belgium from the Allied army of France. The Allied commander-in-chief, General Gamelin, was replaced with General Weygand.
The new commander made a push but was beaten back. Operation Yellow had not only given Germany Belgium, but had defeated the Allied Forces and ended the Battle of France.
