In terms of impact on events, it was more than Napoleon's personality that took effect. He reorganized France itself to supply the men and money needed for great wars. Above all he inspired his men—Wellington said his presence on the battlefield was worth 40,000 soldiers, for he inspired confidence from privates to field marshals. He also unnerved the enemy. At the Battle of Auerstadt in 1806, King Frederick William III of Prussia outnumbered the French by 63,000 to 27,000; however, when he mistakenly was told that Napoleon was in command, he ordered a hasty retreat that turned into a rout. The force of his personality neutralized material difficulties as his soldiers fought with the confidence that with Napoleon in charge they would surely win.
