The author of the published study deals with the fate of the officer engaged in the Three Aldermen (or just Aldermen) group within the anti-Nazi resistance. However, his life was much more colourful and gradually affected perhaps by all the breakthrough moments of our new history. As an 18-year-old young man, he got to the Eastern front as the private of the Austrian-Hungarian Army, where he later fell into captivity and enrolled into the forming Czechoslovak Legions. After fighting in the units of the 8th Rifle Regiment and return to the Free State, he remained in the Army. He completed the military education at the Military Academy in Hranice na Moravě and towards the end of the 1930’s was involved in the search group of the considerably exposed 2nd (intelligence) department of the Headquarters in Prague. Here, he met his future colleagues and friends from the anti-Nazi resistance, in particular the Staff Captains Alois Čáslavka and František Fárek. They were the men he was working with in the Three Aldermen resistance group, specialised mainly in the intelligence activity and significantly cooperating with the exile reporters around the Col. of the Gen. Staff František Moravec. After the group was revealed by the Gestapo, Longa spent the rest of the war in German prisons. In April 1945, he lived to see the liberation, nevertheless, never returned home to his family. Since his liberation practically, he became missing and his fate remain shrouded in mystery until this day.
