If you’re fortunate enough to be in Poland on August 15 you will get to experience a somber national holiday: Polish Army Day. The title sounds vague, but it commemorates the fact that Polish soldiers repulsed an attack from Soviet Cossack units in the 1920 battle of Warsaw during the Polish-Bolshevik war. The Polish 1st Army resisted the Red Army’s direct assault on the capital as well as the attack on the town of Radzymin 23km away. The success of the Polish Army in sending the Soviets packing is often called “the miracle at the Vistula.” Naturally, this holiday didn’t exist while Poland was under communism, but in 1992 the Sejm created the public holiday to coincide with the Assumption of the Blessed Virgin Mary – a two-for-one holiday, if you will. In addition to celebrating past victories, August 15 is also a day of holy masses to honor those who died in battle. Military cemeteries have ceremonies to commemorate the war dead, and in front of the Tomb of the Unknown Soldier in Warsaw the Changing of the Guard of Honor is celebrated with the participation of the Highest State Authorities. In Warsaw celebrations also typically include a speech by the president and parades on Pl. Piłsudskiego (B-2/3) .
