The authors have edited and prepared for publishing an unknown letter by the Przemyśl lawyer, politician and social activist Leonard Tarnawski of 19 November 1914. In the letter Tarnawski appeals to the authorities in Vienna in defense of his unjustly imprisoned brother Apolinary,owner of a clinic in Kosiv in Pokuttya. The letter was written during the First World War, a poorly researched period in the history of the Tarnawski family, and had remained an unknown historical source.
