In the article I explore the circumstances of the origins and evaluate Bronisław Kocowski's book titled "Tatars campaingn on Hungary trough Poland in 1594". The book was written in unusual circumstances - the author began his archival work before World War II and continued it during german occupation of Lviv. Finally the book was published in October 1948 when the political discourse in the Republic of Poland was getting tighten. "Tatars campaign on Hungary trough Poland in 1594" was the second book about military history of the early modern age published after World War II.
