Hello. I am participating in a school competition with my friend and we are completely unable to find the answer to one of the questions. And here's the content: “Immortalized in this valuable photo, taken in Great Britain, is Josef Stříbrný (standing in front third from the right), born in Lidice. Shortly after this photo was taken, he completed a parachute course and it is not impossible that he could have been sent to the occupied homeland as a member of one of our parachute groups. However, he suffered an injury during further training and was therefore transferred to the Air Force. Along with him, however, are immortalized here men who were indeed sent to the protectorate and are among the legends of the Czechoslovak parachute units. How many future paratroopers are in this photo, who were dropped into the occupied homeland between 1941 and 1945?”. The answers are from 2 to 6. This website is our last hope. I appreciate any form of information.
