London government in exile. From 1940, Berling had been involved in efforts to create a Polish division in the Soviet Union, at first within the Soviet Red Army. In September 1942 and during the following months, he and Wanda Wasilewska appealed to Joseph Stalin for permission to establish the Polish division. On 8 April 1943, Berling proposed the establishment of a new Polish army; permission was granted after the break in Soviet-Polish diplomatic relations. In May 1943, the communist-led Polish People's Army was created in the Soviet Union. It was a new formation of Polish Armed Forces in the East. Berling was nominated to be the commander of its first unit, the 1st Tadeusz Kościuszko Infantry Division, and was promoted to general by Stalin. He became the overall deputy commander of the Polish Army on the Eastern Front on 22 July 1944. On 1 August 1944, the underground Polish Home Army, loyal to the Polish government-in-exile in London, began the 63-day long Warsaw Uprising, an attempt to free the city from the occupying German forces before the arrival of the Red Army. On 15–23 September, when the uprising was in its later phase, with his First Polish Army on the east bank of the Vistula River and the Praga district of Warsaw already secured, Berling led a rescue effort that involved crossing the Vistula and establishing a bridgehead on the west bank. The failed operation, possibly not fully consulted with Berling's Soviet military superiors, resulted in heavy Polish Army casualties and may have caused Berling's dismissal from his post soon thereafter. He was transferred to the War Academy in Moscow, where he remained until his return to Poland in 1947. In Poland, Berling organized and directed the Academy of General Staff (Akademia Sztabu Generalnego). He retired from the military in 1953. Government career Zygmunt Berling held a variety of government positions after 1953. Between 1953 and 1956, he was Undersecretary of State in the Ministry of National Agriculture Industries (Ministerstwo Państwowych Gospodarstw Rolnych), between 1956 and 1957 he was Undersecretary of State in the Ministry of Agriculture (Ministerstwo Rolnictwa) and from 1957 to 1970 he was General Inspector of Hunting (Inspektor Generalny Łowiectwa) in the Ministry of Forestry (Ministerstwo Leśnictwa). In 1963, he joined the Polish United Workers' Party. He is buried at Powązki Military Cemetery in Warsaw. Awards and decorations : Order of the Builders of People's Poland Grand
