The Trumpeter of Krakow, a young adult historical novel by Eric P. Kelly, won the Newbery Medal for excellence in American children's literature in 1929.
Centered on the historical fire that burned much of Kraków in 1462, The Trumpeter of Krakow tells the fictional story of a family of Joseph Charnetski, a Polish noble family from Kresy, who fled to Kraków, Poland, in 1461 after their home is burned to the ground by the Cossack-Tartars of Bogdan Grozny, commonly known as "Peter of the Button Face" because of the button-shaped pockmark on his cheek.
