The Second battle of Wawer (Polish: Druga bitwa pod Wawrem) was an armed engagement between Polish and Imperial Russian troops. It happened on 31 March 1831 during the November Uprising^[1] and was one of the first battles of a successful Polish offensive planned by General Ignacy Prądzyński. On March 31, during the period of the Polish operational initiative along the Siedlce road, the Polish grouping nominally commanded by General Jan Skrzynecki (15 battalions, 8 squadrons, 14 cannons) fought a victorious battle with the Russian corps of General Fyodor Gejsmar (6 battalions, 6 squadrons, 7 hundred, 10 department).^[1] The lack of vigorous pursuit meant that the Russians, despite significant losses, managed to maintain combat value. An earlier clash in the same area occurred on February 20, 1831. The Polish success led to another victorious battle of Dębe Wielkie later that day.^[2][3]
