On the Eastern Front, the Soviet Red Army (including the Polish Armed Forces in the East under Soviet command) simultaneously with the Western Allies, had taken most of Poland and began their offensive into Eastern Germany in February 1945, and by March were within striking distance of Berlin. The initial advance into Romania, the First Jassy–Kishinev Offensive in April and May 1944 was a failure; the second Offensive in August succeeded. The Red Army also pushed deep into Hungary (the Budapest Offensive) and eastern Czechoslovakia and temporarily halted at what is now the modern German border on the Oder–Neisse line.
