The Battle of Eylau (7–8 February 1807) during the Napoleonic Wars involved the French troops of Napoleon Bonaparte, the Russian troops of General Bennigsen, and the Prussian troops of General Anton Wilhelm von L'Estocq. Only 3 inhabitants of Eylau died in the battle, but 605 persons died due to hunger and diseases in 1807 (with the average death rate in "normal" years being around 80-90). Napoleon used the local courthouse as his headquarters in Eylau on 7–17 February 1807.
