Battle of Poznań (1945)
The Battle of Poznań (Battle of Posen) during World War II in 1945 was a massive assault by the Soviet Union's Red Army that had as its objective the elimination of the Nazi German garrison in the stronghold city of Poznań (Posen) in occupied Poland. The defeat of the German garrison required almost an entire month of painstaking reduction of fortified positions, intense urban combat, and a final assault on the city's citadel by the Red Army, complete with medieval touches.
