King Michael of Romania led a successful coup with support from opposition politicians and the army, successfully deposing the Antonescu-led governemtn. In a proclamation broadcast on the radio, the King issued a cease-fire just as the Red Army was penetrating into Romanian territory, proclaimed Romania's loyalty to the Allies, announced the acceptance of the armistice offered by Great Britain, the United States, and the USSR, and declared war on Germany. This, however, did not stop the rapidly advancing Soviet force, which captured more than 100,000 Romanian soldiers who were then sent to the Soviet Union's prison camps, where most of them perished. It has been suggested that the coup may have shortened World War II by six months.
