Where did Napoleon keep his armies? In order to concentrate superior combat strength in one place, economy of force must be exercised in other places. Economy of force requires the acceptance of prudent risks in selected areas to achieve superiority at the point of decision. One account has it that Napoleon allowed a subordinate to draw up a plan for the disposition of his troops. Not knowing what the Emperor wanted, the subordinate distributed the forces equally in neat little groups along the border. On seeing it Napolean remarked ""Very pretty, but what do you expect them to do? Collect customs duties?"". Napoleon never encamped or entrenched, it was the general maxim of the war - - where is the enemy ? Let us go and fight him ! ""The strength of an army, like the power in mechanics, is estimated by multiplying the mass by the rapidity; a rapid march augments the morale of an army, and increases its means of victory. Press on!""
