Czech Army Paratrooper and resistance fighter. Assassin of SS Obergruppenfuehrer Reinhard Heydrich.
Together with six other parachutists (Jan Kubis, Josef Bublik , Jozef Gabcík , Adolf Opalka , Jaroslav Švarc , and Jan Hruby), during and after the assassination of Reinhard Heydrich they hid in the crypt of the Orthodox Church of Saints Cyril and Methodius in Prague. Sgt. Valcik and his fellow paras fought it out in prague before being overwhelmed. As a last ditch effort, they killed themselves instead of surrendering to the Nazis. They were betrayed by two of their own fellow soldiers, Sgt. Maj. Karel Curda and Cpl. Viliam Gerik.
