SS and Gestapo. Several Czechs were killed, and the remainder hid in the church's crypt. The Germans attempted to flush the men out with gunfire and tear gas, and by flooding the crypt. Eventually an entrance was made using explosives. Rather than surrender, the soldiers killed themselves. Supporters of the assassins who were killed in the wake of these events included the church's leader, Bishop Gorazd, who is now revered as a martyr of the Orthodox Church. Infuriated by Heydrich's death, Hitler ordered the arrest and execution of 10,000 randomly selected Czechs. But after consultations with Karl Hermann Frank, he altered his response. The Czech lands were an important industrial zone for the German military, and indiscriminate killing could reduce the region's productivity. Hitler ordered a quick investigation. Intelligence falsely linked the assassins to the towns of Lidice and Ležáky. A Gestapo report stated that Lidice, north-west of Prague, was suspected as the assailants' hiding place because several Czech army officers, then in England, had come from there; additionally, the Gestapo had found a resistance radio transmitter in Ležáky. On 9 June, after discussions with Himmler and Karl Hermann Frank, Hitler ordered brutal reprisals. On 9 June, in the village of Lidice 172 boys and men between age 14 to 84 were shot. Thereafter, all adults in Ležáky were murdered. All but four of the women from Lidice were deported immediately to Ravensbrück concentration camp (four were pregnantthey were subjected to forced abortions at the same hospital where Heydrich had died and the women were then sent to the concentration camp). Some children were chosen for Germanization, and 81 were murdered in gas vans at the Chełmno extermination camp. Both towns were burned and Lidice's ruins were levelled. Overall, at least 1,300 Czechs, including 200 women, were killed in reprisal for Heydrich's assassination. Heydrich's replacements were Ernst Kaltenbrunner as the chief of RSHA, and Karl Hermann Frank (27–28 May 1942) and Kurt Daluege (28 May 194214 October 1943) as the new acting Reichsprotektors. After Heydrich's death, implementation of the policies formalised at the Wannsee conference he chaired was accelerated. The first three true death camps, designed for mass murder with no legal process or pretext, were built and operated at Treblinka, Sobibór, and Bełżec. The project was named Operation Reinhard after Heydrich. Service record Heydrich's time in the SS was a mixture of rapid promotions, reserve commissions in the regular
