Janowa Dolina massacre
The Janowa Dolina massacre took place on 23 April 1943 in the village of Janowa Dolina, (now Bazaltove, Ukraine) during the occupation of Poland in World War II. Before the Nazi invasion of the Polish Second Republic, Janowa Dolina was a model settlement built in the Kostopol County of the Wołyń Voivodeship by workers of the Polish State Basalt Quarry. The town was inhabited by 2,500 people. Its name, which translates as the "Janow's Valley" in Polish, came from the Polish king Jan Kazimierz, who reportedly hunted in the Volhynian forests, and after hunting — rested on the shore of the Horyń (Horyn) River. The town was destroyed during World War II by the Ukrainian Insurgent Army who murdered most of its Polish population including women and children.
