Can you understand that you can't conduct a large-scale partisan movement in a densely populated area without appropriate natural conditions? The Czechoslovak government in Britain obviously didn't have any clue about the situation in the Protectorate either. Furthermore, the country was infiltrated by Czech-speaking German agents recruited from Sudeten Germans. The average survival time of a parachutist sent from Britain was not much longer than 6 months.
