In London, the Czechoslovak government in exile resolved to kill Heydrich. Two men specially trained by the British Special Operations Executive (SOE), Jan Kubiš and Jozef Gabčík, were chosen for the operation.
On 27 May 1942, Heydrich was scheduled to attend a meeting with Hitler in Berlin. On that date, Heydrich was ambushed while he rode in his open car in the Prague suburb of Libeň. As the car slowed to take the turn, Gabčík took aim with a Sten sub-machine gun, but it jammed and failed to fire. Instead of ordering his driver to speed away, Heydrich called his car to a halt in an attempt to take on the attackers. Kubiš then threw a bomb (a converted anti-tank mine) at the rear of the car. The explosion wounded Heydrich. He had suffered a severe injury to the left side of his body with major damage to his diaphragm, spleen, and lung, as well as a broken rib. Heinrich Himmler ordered Dr. Karl Gebhardt to fly to Prague and take over Heydrich’s care. Despite a fever, his recovery appeared to progress well. After Himmler’s visit, Heydrich slipped into a coma and never regained consciousness. He died on the 4th of June, probably around 4:30 a.m. at the age of 38. The autopsy states that he died of septicemia.
