What were the results of the Battle of Eylau?

The Battle of Eylau, fought on February 7–8, 1807, resulted in a bloody tactical stalemate that marked the first major deadlock for Napoleon during the Napoleonic Wars.1

The engagement concluded with both sides suffering heavy losses—at least 15,000 casualties for the French and 15,000 for the Allied Russian-Prussian forces, though some estimates place the figures higher. Following the exhaustion of both armies, the Russian commander Leonty Leontyevich Bennigsen withdrew from the battlefield during the night. However, the French were in no condition to pursue their opponents, and Napoleon himself remarked that the Russians had done his army great harm.12

Ultimately, both sides claimed victory before retreating to winter quarters, effectively halting major combat operations until the spring. The battle is also remembered for the horrific conditions, as the extreme winter weather caused many of the wounded to freeze to death in the aftermath.12
