"After defeating the Prussian army in the autumn of 1806, Emperor Napoleon entered partitioned Poland to confront the Russian army, which had been preparing to support the Prussians until their sudden defeat. Crossing the River Vistula, the French advance corps took Warsaw on 28 November 1806. The Russian army was under the overall command of Field Marshal Mikhail Kamensky, but he was old and becoming infirm. The Russian First Army of some 55,000 to 68,000 men, commanded by Count Bennigsen, had fallen back from the Vistula to the line of the River Wkra (Ukra), in order to unite with the Second Army, about 37,000 strong, under General Friedrich Wilhelm von Buxhoeveden (Buxh\u00F6wden), which was approaching from Russia and was still several days march from the First Army. However, realising his mistake in allowing the French to cross the Vistula, Kamensky advanced at the beginning of December to try to regain the line of the river. French forces crossed the Narew River at Modlin on 10 December, and the Prussian Corps commanded by General-Leutnant Anton Wilhelm von L'Estocq failed to retake Thorn (Toru\u0144). This led Bennigsen on 11 December to issue orders to fall back and hold the line of the River Wkra. When this was reported to Napoleon, he assumed the Russians were in full retreat. He ordered the forces under Marshal Joachim Murat \u2013 the 3rd corps of Marshal Louis Nicolas Davout, 7th Corps of Marshal Pierre Augereau, 5th Corps under Lannes, and Murat's 1st Cavalry Reserve Corps \u2013 to pursue towards Pu\u0142tusk. Meanwhile, Marshal Michel Ney's 6th Corps, Marshal Jean-Baptiste Bernadotte's 1st Corps, and Marshal Jean-Baptiste Bessi\u00E8res's 2nd Cavalry Reserve Corps turned the Russian right. Marshal Nicolas Soult's 4th Corps linked the two wings of the French army. Kamensky reversed the Russian retreat, and he ordered an advance to support the troops on the River Wkra. On the night of 23 and 24 December, Davout's corps forced a crossing of the lower Wkra in the Battle of Czarnowo. After engagements at Bie\u017Cu\u0144 on 23 December with Bessi\u00E8res and Soldau (Dzia\u0142dowo) on 25 December with Ney, the Prussian corps under L'Estocq was driven north towards K\u00F6nigsberg. Augereau's corps seized a second crossing of the Wkra on the 24th at Ko\u0142oz\u0105b. Realising the danger, Kamensky ordered a retreat on Ostro\u0142\u0119ka. At this time the old field marshal appears to have had a mental breakdown and returned to Grodno. Bennigsen decided to disobey his superior's orders by standing and fighting on 26 December at Pu\u0142tusk. He had available the 2nd Division of Lieutenant General Alexander Ivanovich Ostermann-Tolstoy, the 6th Division of Lieutenant General Alexander Karlovich Sedmoratski, part of Lieutenant General Dmitry Golitsyn's 4th Division, and part of Lieutenant General Fabian Gottlieb von Osten-Sacken\u2019s 3rd Division. To the north-west, most of the 4th Division commanded by Golitsyn and the 5th Division under Lieutenant General Dmitry Dokhturov fought the Battle of Go\u0142ymin on the same day."@en .
