After the Soviets won back their own country, they pushed westward to release Romania, Bulgaria, Hungary, Czechoslovakia, Albania and Yugoslavia from German occupation. One of the bloodiest battles was for Budapest. The Hungarians had attempted to rise up against the Nazis, but the Germans brutally repressed them as the Soviet forces approached the city. The Russians then fought their way into the ancient Hungarian capital. More than one million Red Army men and women gave their lives in a savage battle to drive the Nazis out of Eastern Europe. The final victory was not won until the Soviet forces freed Vienna, as U.S. troops entering from the west and the Red Army entering from the east liberated Czechoslovakia.
