The Warsaw uprising was a resistance operation by the Polish Home Army during World War II. The goal of the operation was the liberation of the Polish capital, Warsaw, from German hands. The uprising was timed to coincide with the Red Army’s approach to the city. The Red Army however stopped its advance before entering the city, therefore enabling the Wehrmacht to regroup and defeat the uprising. The uprising began as part of a nation-wide anti-Nazi operation called Operation Tempest, or Plan Burza in Polish.
