Battles of Pultusk and Golymin: Russian forces hold French forces under Napoleon.

The Battle of Pułtusk took place on 26 December 1806 during the War of the Fourth Coalition near Pułtusk, Poland. Despite their strong numerical superiority and artillery, the Russians suffered the French attacks, before retiring the next day having suffered greater losses than the French, disorganizing their army for the rest of the year.

The Battle of Golymin took place on 26 December 1806 during the War of the Fourth Coalition at Gołymin, Poland, between around 17,000 Russian soldiers with 28 guns under Prince Golitsyn and 38,000 French soldiers under Marshal Murat. The Russian forces disengaged successfully from the superior French forces. The battle took place on the same day as the Battle of Pułtusk.

The French Empire, known retroactively as the First French Empire, was the empire ruled by Napoleon Bonaparte, who established French hegemony over much of continental Europe at the beginning of the 19th century. It lasted from 18 May 1804 to 6 April 1814 and again briefly from 20 March 1815 to 7 July 1815, when Napoleon was exiled to Saint Helena.

Napoleon Bonaparte, later known by his regnal name Napoleon I, was a French general and statesman who rose to prominence during the French Revolution and led a series of military campaigns across Europe during the French Revolutionary and Napoleonic Wars from 1796 to 1815.

He was King of Italy from 1805 to 1814 and Protector of the Confederation of the Rhine from 1806 to 1813.
