Jozef Gabčík (8 April 1912 – 18 June 1942) was a Slovak soldier involved in the British backed assassination of Nazi Reinhard Heydrich in Prague, Czechoslovakia in 1942. He and his friend and partner Jan Kubiš were able to fatally wound Heydrich, and flee. However, they and other anti-German partisans were traced to a church. After a six hour gun battle, Gabčík ended his life with a grenade rather than face capture.
