Battle
Snow, staggered reinforcements, an elusive decision
Military history
Eylau unfolds in two stages: contact on 7 February fixes the French centre around the town, then the battle on 8 February unsuccessfully seeks to turn local advantages into a breakthrough. Snow disorients Augereau's attack, Murat's charge prevents the centre from collapsing, Davout weighs on the Russian wing, and Lestocq supports it before Ney's late arrival. The French hold the field, but the Russian army is not destroyed, and both casualty totals and the claimed victory remain disputed.
On 7 February, fighting at Ziegelhof delays the French entry. Murat and Soult then take Eylau and its cemetery while the Russian army forms on the neighbouring heights. The town becomes a strongpoint to hold; the battle's decision remains open.
During the night, the French centre remains around Eylau while Davout approaches from the southeast and Ney from the northwest. The sequence is a relational reconstruction: the sources give axes and arrival times, but the maps do not justify an exact pre-dawn position for every corps.
On 8 February, the cannonade and Russian attacks begin before all French components have assembled. Davout advances towards Serpallen; Augereau's attack drifts in the snow, loses direction, and leaves a gap that the Russians exploit before Murat's charge.
Davout threatens the Russian wing, Lestocq arrives from the west late in the day, and Ney reaches the sector at nightfall. Bennigsen orders a withdrawal; the French hold the ground but cannot pursue. Possession of the field, losses, and the battle's political significance must be kept separate.
