Jozef Gabčík in the context of Czechoslovak Army

Reinhard Heydrich, the commander of the German Reich Security Main Office (RSHA), the acting Reichsprotektor of the Protectorate of Bohemia and Moravia and a principal architect of the Holocaust, was assassinated during the Second World War in a coordinated operation by the Czechoslovak resistance. The assassination attempt, code-named Operation Anthropoid, was carried out by resistance operatives Jozef Gabčík and Jan Kubiš on 27 May 1942. Heydrich was wounded in the attack and died of his injuries on 4 June.

The operatives who carried out the assassination were soldiers of the Czechoslovak Army who were prepared and trained by the British Special Operations Executive (SOE) with the approval of the Czechoslovak government-in-exile, led by Edvard Beneš. The Czechoslovaks undertook the operation to help confer legitimacy on the government-in-exile, and to exact retribution for Heydrich's brutal rule. The operation was the only verified government-sponsored assassination of a senior Nazi leader during the war. Heydrich's death led to a wave of reprisals by SS troops, including the destruction of villages and mass killings of civilians, including the Lidice massacre.
