Napoleon had many qualities that made him perhaps history’s greatest general, but the one that raised him to the heights and kept him there was his boundless energy. During campaigns he worked eighteen to twenty-hour days. If necessary, he would go without sleep for several days, yet sleeplessness rarely reduced his capacities. He would work in the bath, at the theater, during a dinner party. Keeping his eye on every detail of the war, he would ride endless miles on horseback without tiring or complaining.
