Commemoration
After the war, the village of Trigubovo was renamed Kostyushko, a Russian rendering of the name of Tadeusz Kościuszko, the name-sake of the Polish division. On October 7, 1950, the anniversary of the battle was declared the official "Day of the Polish Army" by the authorities of the People's Republic of Poland. In 1989, when Poland quit the Warsaw Pact and Soviet sphere of influence, the day was replaced by the pre-war Day of the Polish Army date of August 15, which commemorates the Battle of Warsaw in 1920.
