A National Democrat Sejm deputy, Stanisław Stroński, coined the phrase, "Miracle at the Vistula" (Polish: ""Cud nad Wisłą""), to underline his disapproval of Piłsudski's earlier "Ukrainian adventure." In response, Poland's Prime Minister Wincenty Witos commented, "Whatever you want to write and say – whoever you want to dress in laurels and merits – this "is" 1920's 'Miracle at the Vistula.'" Diaries from many participants of the battle attribute the outcome to the Blessed Virgin Mary citing multiple reasons, including widespread national prayer beforehand and subsequent reports of her appearance on the battlefield. The date of the turn of the battle is believed to coincide with the Solemnity of the Assumption of the Blessed Virgin Mary as celebrated by Roman Catholics.
