are you talking about this or something else:
The trumpet call "Hejnal Mariacki" ("Hymn to our Lady")-is played daily from the tower of St. Mary's Basilica in Krakow. This signal, known and dear to every Pole, resounds all over the city's Old Town historical district. The song dates back to the Middle Ages when it announced the opening and the closing of the city gates. It was also played to alarm citizens of fires or approaching enemy forces. The call always ends abruptly to commemorate a bugler shot through his throat by a Tatar archer in 1241.
The lyrics of "Boze Cos Polske" ("God Save Poland"), which became Poland's national hymn in 1830, were changed to the prayer "Serdeczna Matko" ("Beloved Mother"), when singing of the anthem was outlawed by Poland's occupying powers.
And in 1920, when Russian forces were assembling on the banks of the Wisla in preparation for an attack on Warsaw, an image of Mary was seen in the clouds. "Cud na Wisla" ("The Miracle on the Wisla") is a story known by every Pole.
