Romania surrenders to the Soviet Union

The Red Army renewed its attack on Romania on 20 August, occupying Iasi on 23 August. In an anti-fascist rebellion, King Michael arrested Marshal Ion Antonescu, overthrew his regime and formed a new government under the leadership of General Sanatescu. By the end of August, the Soviets had decimated a large percentage of the German troops in Romania, and occupied main cities including Bucharest, and King Michael had declared war on Germany. With the surrender of Romania to the Soviet Union, Germany lost most of its oil supply, and all the Romanian produce.
