When the Kingdom of Holland was incorporated into France in 1810, Daendels returned to Holland. In November 1811 he lived in Paris. He was appointed a Divisional General (Major General) and commanded the 26th Division of the Grande Armée which was formed of troops from Baden, Hesse-Darmstadt, and Berg. Mid March 1812 he seems to have been appointed as commander of the 26th division and served as part of IX Corps under Marshal Victor intended as a reserve. In August Victor was told to assist and to march the East according to . On 8 and 15 September Daendels arrived in Vilnius, then in Minsk. On 11 October this division went to Babinovichi. On 20 October he was ordered to go to Vitebsk and on 27 October they occupied nearby Beshankovichy. The temperatures dropped below zero on the next day. The supplies in Vitebsk were lost when the Russian army captured the city. On 29 October it began to snow. On 11 November the rearguard with Daendels arrived in Chashniki, about 90 km SW. On 14 November in the battle of Smoliani the French lost 3,000 men against General Peter Wittgenstein; about 1.5 meter of snow fell on that day. Four days later the supplies in Minsk were lost when Pavel Chichagov captured the city. On 24 November he was jostled by Russians but succeeded to join the rest of the French army near Bobr. All the French corpses went on to Borisov where a strategic bridge to cross the Berezina was destroyed by the Russian army. Daendels' division of 4,000 men was involved in the Battle of Berezina and seems to have been decisive. Polish forces under general Daendels defended the Modlin Fortress (NW of Warsaw) from February 1813 until December 1813. It was the last of the French fortresses along the Vistula to capitulate.
