As part of Hitler's strategy to invade France in 1940, the German Army pretended that they were going to invade through Belgium, similar to 1914. General Maurice Gamlin fell for it and sent his best motorized divisions and the entire British Expeditionary Force to stop the advance

In reality, the Germans invaded France through the Ardennes, previously deemed by French military leaders to be impassable, and attacked the Allied forces from their undefended rear after the German victory at Sedan. The resulting battles weakened the French military significantly and led to the French surrender on 25th June 1940.

But what if General Gamlin was able to realize that the German invasion of Belgium was a decoy and decided, instead, to launch an attack on the German forces in the Ardennes?
