How Napoleon Turned Roads Into a Weapon

At Ulm in 1805, the decisive advantage was not simply marching faster. The French army used several roads, a cavalry screen, messages and a turn toward the Danube to change the map before Austrian command had an easy answer. But the plan also jammed at crossings, exposed its supply trains, and left one route north open. Question for the map: if you were watching the French screen from the Austrian side, would you retreat early—or wait for confirmation?
