In the face of nature, humans are fragile. The battle of the Rhine River is still ongoing, but the intensity of the war was limited by the heavy snowfall.
It's not that the attacking French Army wasn't trying hard, but the snowy weather was too much to handle. It affected not only the offensive on the front line but also increased the difficulty of logistical transportation.
An army of two million, even if idle, consumes astronomical amounts of supplies every day, not to mention when they are engaged in combat.
It was once again proven, combat deep in enemy territory is not that simple.
Indeed, Belgium and the Rhineland region are areas with convenient transportation and a well-established railway network, but the problem is, the Allied Forces had damaged the roads during their retreat!
Destruction is always easier than construction, and the first task for the French Army after occupying these areas was road repair.
