In Poland the 15th of August is the Polish Army Day, connected with the anniversary of the Battle of Warsaw in 1920, also known as the Miracle upon the Vistula. The day is also the Day of Assumption.
The victorious Warsaw Battle, fought on 12-25 August 1920, during the war between Poles and the Bolsheviks, is considered a breakthrough in the history of the world. It was decisive not only for the independence of Poland, but it also protected the entire Europe from the spread of communism and soviet totalitarianism.
To celebrate the day, garrison churches hold masses on behalf of soldiers, who fell in the fields of glory, and readings of the roll of the dead take place in cemeteries. The Change of Guards takes place before the Tomb of the Unknown Soldier in Warsaw, attended by the Polish State authorities.
The Day of Assumption, also known in Poland as the Day of Blessed Mother of Herbs, is celebrated in the Catholic Church throughout the world. It is usually combined with the tradition of blessing and making an offering of herbs, crops, vegetables and flowers. Blessed crops are to secure safe and harmonious home all year long.
On the 15th of August ceremonious masses are held in all churches. The Sanctuary of Jasna Góra in Częstochowa is the point of destination of pilgrimages from all over Poland. The pilgrims pray and sing while walking hundreds of kilometres for more than a dozen days.
