What if an EF5 tornado crossed the Ardennes just as the German army entered in 1940?
Short answerIt could seriously disrupt horse-drawn logistics along its damage path. The effect on the offensive would depend on where it struck and how the Germans responded.
NotesAn EF5 tornado crossing the advancing German army could damage the horse-drawn transport on which much of its logistics depended. The storm used for comparison lasts only about 16 minutes, but its track is described as roughly 12 miles long and a mile wide. That would expose a substantial stretch of the advance to disruption despite the short duration. The operational consequences would depend on how the Germans reacted. The answer even allows that the storm might clear a path while causing serious problems elsewhere.
