In January 1863, the Polish January Uprising broke out. Among local Polish insurgents were many young people and Poles conscripted into the Russian army, who were stationed in the city. The Russians established a prison for captured insurgents in Piotrków. Thousands of Poles passed through the prison, were subjected to flagellation and tortures, and then either deported to the Warsaw Citadel or to Siberia, or executed in Piotrków. Two insurgents, wanting to escape from torture, committed suicide by jumping out of the prison windows. As punishment for supporting the uprising, the Russians closed down the Bernardine monastery in 1864, and the last Bernardine monks were expelled in 1867.
