Cause

Germany's Fall Gelb plan called for Army Group A to advance through the Ardennes, a hilly and forested region considered difficult for large armored forces. The intent was to strike at the weak hinge of the Allied line near Sedan, cross the Meuse, and swing northwest to the Channel coast, thereby encircling the Allied armies advancing into Belgium under the Dyle Plan.

Event

Between 12 and 15 May 1940, German forces captured Sedan and crossed the Meuse in strength. Luftwaffe bombing and low French morale prevented the destruction of the bridgeheads. On 14 May, a combined RAF and French air attack failed to eliminate the crossings, with Allied bombers suffering severe losses in ensuing air battles. French counter-attacks from 15 to 17 May were undone by delay and confusion.

Consequence

By 20 May, German forces had reached the English Channel, completing the encirclement of the British Expeditionary Force and the strongest Allied armies. The successful Meuse crossing fulfilled the core objective of Fall Gelb. Subsequent fighting in June destroyed the remaining French army as an effective force, expelled the British from the continent, and culminated in the defeat and occupation of France.
