Battle of Pułtusk

Battle context

The Battle of Pułtusk was fought on 26 December 1806 during the War of the Fourth Coalition, pitting a French force of roughly 25,000–27,000 men under Marshal Jean Lannes against a Russian army of 40,000–45,000 under General Levin von Bennigsen. Despite their numerical superiority and artillery advantage, the Russians absorbed heavy French attacks before withdrawing the following day. Casualties on both sides were substantial and roughly comparable—approximately 3,300 French and 3,500 Russian—leaving the Russian force disorganized for the remainder of the year. The battle denied Bennigsen the ability to exploit his numerical edge and disrupted Russian cohesion at a critical moment in the winter campaign, limiting Russian operational effectiveness in the weeks that followed.
