An important support of the Czechoslovak resistance movement during the First World War were the Czechoslovak Legions, which originated abroad (Italy, France and Russia). The Legions in Russia began to form from the beginning of the war, and the wider recruitment of war prisoners was gradually allowed.
However, recruitment among Slovak prisoners was not as successful as in the Czech case. The paper deals with how the representatives of the resistance movement ( The Branch of Czechoslovak National Council in Russia) tried to solve this situation and what problems they had to deal with.
