Juliusz Konstanty Ordon[1][2] (born in Warsaw, 16 October 1810, died in Florence, 4 May 1887) was a participant of the Polish November Uprising in 1830-1831.
Ordon distinguished himself as a commander of one of the reduta strongholds in Wola during the storm of Warsaw by Russian Army in September 1831. In the last moments of its defence the reduta was blown up by one of the defenders, who was mistakenly identified as Ordon. He was immortalized in the poem of Adam Mickiewicz, Reduta Ordona.
Apparently this was not the case since he survived the assault and was taken war prisoner by Russians. Later on, Ordon always denied such bravery.
