Two brothers, František (1891-1956) and Alois (1897-1992) came from the family of a small farmer in the village of Senetářov in the Drahany Highlands. The older František was in the second year of his military service when the First World War broke out, the younger Alois was conscripted. Gradually they were both taken captive, and later got into the legions, with which they went along the whole Siberian railway. They met in Siberia as late as on Christmas Eve 1919. They were demobilized at the turn of the year 1920-1921. Several letters by František addressed to his chosen one and later wife have been preserved; the younger Alois wrote fresh memoirs immediately after his return describing not only war events, the situation in Russia where Soviets were assuming power, but also the relationships among legionnaires. These are unique sources offering authentic personal testimonies of WW1 participants.
