On 29 November 1830 the Poles began the November Uprising against their Russian occupiers. On 10 February 1831 Łubieński was made commander of the 2nd Cavalry Corps, made up of 33 battalions and 16 cannon. After the First Battle of Wawer, he and his corps did not fight despite receiving orders to do so, due to what he felt was the overwhelming numerical superiority of the Russian forces. Józef Chłopicki and Ignacy Prądzyński accused him of treason and ruining the last chance of a victory by refusing to obey an order to attack with his cavalry at Olszynka Grochowska. Historians have justified his disobedience as a good decision since sacrificing his cavalry could not have changed the course of the battle.
