Battle of Zadwórze

Battle of Zadwórze (sometimes referred to as the "Polish Thermopylae") took place during the Polish-Soviet War. It was fought on 17 August 1920, near the railway station of Zadwórze, a small village located 33 kilometres from the city centre of Lwów (now Lviv). The battle, lasting roughly 24 hours, resulted in the complete destruction of the Polish forces but at the same time halted the Soviet advance, preventing the forces of Siemion Budionnyi from seizing Lwów and so contributing to the successful defence of Warsaw. The battle has been called a Polish Thermopylae.
