This short describes my moving experience in August 2023 in the Crypt of the Cathedral of Saints Cyril and Methodius, where 7 paratroopers, 2 of whom had been the assissinators of Heydrich under Operation Anthropoid in May 1942, died following betrayal, attack and flooding. I used still shots not video as the crypt of a church is not the right place to film live: out of respect, nor for the experience and inspiration, nor even for recording, as other voices would be picked up too. I did several takes on the later voiceover and actually learnt a lot about the complex art of film making in the while process. Deliberate black screen at end to give some idea of being locked in a crypt!
