The Lidice massacre was the complete destruction of the village of Lidice, in the Protectorate of Bohemia and Moravia, now the Czech Republic, in June 1942 on orders from Adolf Hitler and Reichsführer-SS Heinrich Himmler.
In reprisal for the assassination of Reich Protector Reinhard Heydrich in the late spring of 1942, all 173 men from the village who were over 15 years of age were executed on 10 June 1942. A further 11 men from the village who were not present at the time were later arrested and executed soon afterwards, along with several others who were already under arrest. Out of a total 503 inhabitants, 307 women and children were sent to a makeshift detention center in a Kladno school. Of these, 184 women and 88 children were deported to concentration camps; 7 children who were considered racially suitable and thus eligible for Germanisation were handed over to SS families, and the rest were sent to the Chełmno extermination camp, where they were gassed.The Associated Press, quoting German radio transmissions which it received in New York, said: "All male grownups of the town were shot, while the women were placed in a concentration camp, and the children were entrusted to appropriate educational institutions." Approximately 340 people from Lidice were murdered in the German reprisal (192 men, 60 women and 88 children). After the war ended, only 143 women and 17 children returned.
