After fourteen hours of fighting, either army occupied the same position as in the morning.

Twelve of Napoleon's eagles were in the hands of Bennigsen, and the field between was covered with 50,000 corpses, of whom at least half were French.
Either leader claimed the victory; Bennigsen exhibiting as proof of his success the twelve eagles which his army, admitted to be inferior in numbers, bore off the field: Buonaparte, that he kept possession of the field, while the enemy retired, the very night after the battle, from Eylau towards Konigsberg.

It was, in truth, a drawn battle; and to have found an equal was sufficient bitterness to Napoleon.

The Russian general-in-chief had retreated, in opposition to the opinion of most of his council, out of anxiety for the personal safety of the King of Prussia at Konigsberg, and desire to recruit his army ere another great action should be hazarded.

The French, triumphant as was the language of their bulletins, made no effort to pursue.
