In 1923, a group of unknown Varsovians placed, before Warsaw's Saxon Palace and the adjacent Saxon Garden, a stone tablet commemorating all the unknown Polish soldiers who had fallen in World War I and the subsequent Polish-Soviet War. This initiative was taken up by several Warsaw newspapers and by General Władysław Sikorski. On April 4, 1925, the Polish Ministry of War selected a battlefield from which the ashes of an unknown soldier would be brought to Warsaw. Of some 40 battles, that for Lwów was chosen. In October 1925, at Lwów's Cemetery of the Defenders of Lwów, three coffins were exhumed: those of an unknown sergeant, corporal, and private. The coffin that was to be transported to Warsaw was chosen by Jadwiga Zarugiewiczowa, mother of a soldier who had fallen at Zadwórze and whose body had never been found.
