In retaliation against this betrayal, the "Luftflotte" bombed Bucharest and "Casa Nouă", the main residence of the sovereign and his mother since 1940, which was largely destroyed (24 August 1944). Nevertheless, the Romanian forces gradually managed to push the Germans out of the country and also attacked Hungary in order to liberate Transylvania (Siege of Budapest, 29 December 1944 – 13 February 1945). However, the Allies did not immediately recognize the reversal of Romania and the Soviets entered the capital on 31 August 1944. An armistice was finally signed with Moscow on 12 September 1944, which forced the kingdom to accept the Soviet occupation. A climate of uncertainty swept the country while the Red Army increased their demands.
