Using specialized sources such as legionary literature (a vast sub-genre of Czech fi ction between the two world wars), memoirs, diaries, photographs, and personal effects, the author seeks in this article to portray the everyday life of the Czechoslovak legionaries in Russia from 1918 to 1920. To a considerable extent their lives were linked to their being moved about by train. At the centre of this were the tepluskas, furnished and heated box cars, part of the eshelons (troop trains), which served as the makeshift homes in which they spent most of their time. The Czechoslovak volunteers boarded the tepluskas in the spring of 1918, after retreating from the troops of the Central Powers in Ukraine. They then headed for Vladivostok, where they were meant to board ship and sail to France. As things turned out, however, the legionaries remained in Russia far longer, and fought in battles against the Bolsheviks, at fi rst to save themselves, but later, on the side of the Entente, in support of Masaryk’s foreign policy and the creation of an independent Czechoslovakia. The author concentrates more on the living conditions, activities, and customs of the legionaries in tepluskas. He discusses the furnishings of them, the way they were decorated, and their adaptation to the current needs of the legionaries. Last but not least, he attempts to describe how the legionaries experienced their milieu and how it infl uenced their lives together. The author seeks to provide a vivid picture of the “army” on wheels, which changed considerably over time.
