For Davout, 13 miles away at Auerstädt, that same day defeated Frederick William and Brunswick, the former escaping only after many hours in the saddle, and the latter dying of his wounds shortly after the battle. With 30,000 men and 46 guns, Davout had performed a double envelopment on the 52,000 Prussians with their 163 guns, losing 7,000 French soldiers killed and wounded in that bloody engagement, but inflicting almost twice as many casualties on the Prussians.
