The Battle of France, also known as the Fall of France, was the German invasion of France and the Low Countries. In the six weeks from 10 May 1940, German forces defeated Allied forces by mobile operations and conquered France, Belgium, Luxembourg and the Netherlands, bringing land operations on the Western Front to an end until 6 June 1944.
The German plan for the invasion consisted of two main operations. In Fall Gelb (Case Yellow), German armoured units pushed through the Ardennes and then along the Somme valley, cutting off and surrounding the Allied units that had advanced into Belgium, to meet the expected German invasion. When British, Belgian and French forces were pushed back to the sea by the mobile and well-organised German operation, the British evacuated the British Expeditionary Force (BEF) and several French divisions from Dunkirk in Operation Dynamo.
After the withdrawal of the BEF, the German forces began Fall Rot (Case Red) on 5 June. The sixty remaining French divisions made a determined resistance but were unable to overcome the German air superiority and armoured mobility. German tanks outflanked the Maginot Line and pushed deep into France. German forces occupied Paris unopposed on 14 June, after the flight of the French government and the collapse of the French army. German commanders met with French officials on 18 June to negotiate an end to hostilities.
