This documentary film is based on reconstructed and colorized archival materials from the Polish-Soviet war of 1920, which ended with one of the greatest military successes of the Polish nation. The “War of the Worlds” also uses radio recordings, reports of participants and witnesses of events, as well as archival material testimonies that have survived to our times: photos, military orders, and records of secret reports. TVP did digital reconstructions of hundred-year-old, unpublished, archival films, including from Russia, France, Great Britain, the Czech Republic, Hungary, and the USA. In August 1920, one of the most important battles for Poland was fought – the Battle of Warsaw, known as the Miracle on the Vistula. The Polish-Soviet war, however, started much earlier, ended much later and was not limited to the defense of Warsaw; on the contrary, it took place in the area from Smoleńsk to Warsaw, from Płock to Lviv. It was not a miracle, but the effect of the perfect synchronization of command, intelligence, and bravery of soldiers.
