Large-scale Allied bombings of Bucharest took place in spring 1944, while the Soviet Red Army approached Romanian borders. The Battle for Romania began in late summer: while German commanders Johannes Frießner and Otto Wöhler of the Army Group South Ukraine attempted to hold Bukovina, Soviet Steppe Front leader Rodion Malinovsky stormed into the areas of Moldavia defended by Petre Dumitrescu's troops. In reaction, Antonescu attempted to stabilize the front on a line between Focșani, Nămoloasa and Brăila, deep inside Romanian territory. On 5 August, he visited Hitler one final time in Kętrzyn. On this occasion, the German leader reportedly explained that his people had betrayed the Nazi cause, and asked him if Romania would go on fighting (to which Antonescu reportedly answered in vague terms). After Soviet Foreign Minister Vyacheslav Molotov more than once stated that the Soviet Union was not going to require Romanian subservience, the factions opposing Antonescu agreed that the moment had come to overthrow him, by carrying out the Royal Coup of 23 August. On that day, the sovereign asked Antonescu to meet him in the royal palace building, where he presented him with a request to take Romania out of its Axis alliance. The "Conducător" refused, and was promptly arrested by soldiers of the guard, being replaced as Premier with General Constantin Sănătescu, who presided over a national government.
