In the first half of February 1656, an unknown account by Father Augustyn Kordecki about the siege of Jasna Góra by the Swedes in November-December 1655 was published in Vienna in the publishing house of the famous imperial typographer and publisher of court newspapers, Stanisław Mateusz Kosmerowiusz. An account by the prior of the Pauline monastery, written On December 31, 1655, she initiated the so-called anonymous Viennese-Polish newspaper series, published under the inspiration of Queen Louise Maria and Primate Andrzej Leszczyński in the publishing house of S. M. Kosmerowiusz in the years 1656-1658. The series was devoted exclusively to reporting on the course of the Polish-Swedish war in the period in question. It had a decidedly pro-Catholic character and was addressed primarily to Catholic circles in the Habsburg Monarchy and the German Reich, successfully fulfilling the function of an organ exposing the practices of fighting the Catholic Church in Poland by Charles Gustaf and his Protestant and Arian supporters. The publication of a Viennese-Polish serial newspaper in the Habsburg capital was an important achievement of the Polish royal court and the episcopate, on whose initiative similar newspapers appeared at the same time and earlier in Paris, Brussels and the Netherlands. The newspaper became an important historical source for the history of Poland. It published, among others: files of the Łańcut-Zambrów Confederation, the text of the famous Lviv vows of King John Casimir, reporting letters of the Polish king, Fr. T. Bronowski, outstanding Polish generals S. Czarniecki, J. Lubomirski and W. K. Gosiewski, Primate A. Leszczyński, Vice-Chancellor Bishop A. Trzebicki, the Queen's secretary P. Des Noyers and many other personalities from various state, military and church circles. Almost exclusively military, political and religious events in Poland were reported, some of which are unknown in historiography.
