Operation Autonomous was a clandestine operation carried out on the territory of Romania by the Special Operations Executive (SOE) set up by Churchill for the duration of the war to assist local Resistance movements.


In 1943, three secret agents were parachuted into Romanian territory:

Operation aims and outcomeEdit

The aim of the operation was primarily political:

  • to persuade Romanian politicians, especially Iuliu Maniu, the leader of the National Peasant Party, to negotiate an armistice with the Allied Powers.
  • in case they were captured by authorities loyal to the Antonescu government, to convince the Romanian secret during their interrogation, that the allies were preparing to land in the Balcans, hoping that this would induce a concentration of German troups to the east, reducing their firepower in Normandy.

On the night of 22 December 1943 the three agents were parachuted into thick fog and some distance away from the target. They were captured by Romanian gendarmerie almost immediately near the locality of Plosca parish, Teleorman county. They were held as well-treated prisoners of war at the Gendarmerie headquarters in Bucharest under the care of gen. Constantin Tobescu, major Constantin C. Roșescu and of major Eugen Dobrogeanu. Churchill promptly sent a message to Marshal Antonescu warning him that should the British prisoners fall into German hands he would be held personally responsible. The Prime Minister had been told that de Chastelain had information which in German hands could change the outcome of the war.

On 23 August 1944, the young King Michael of Romania, at considerable personal risk, carried out his well prepared coup d'état which took Hitler completely by surprise and so Romania entered the war against the Axis. The British prisoners were released and that evening the King arranged for de Chastelain to fly to Istanbul from where he could go to Cairo and London to report. Meţianu stayed on for a time and then returned to England. Porter remained to maintain a radio link with SOE Headquarters until the British mission arrived. He later worked at the Legation and in 1948 returned to London to the Foreign Office.


After the start of the Cold War, Soviet authorities alleged that de Chastelain was keeping contacts with Iuliu Maniu, the leader of the National Peasants' Party; the latter had opposed both Antonescu's regime and the Soviet occupation of Romania. During Maniu's trial for treason in 1947, the Minister of the Interior, Teohari Georgescu, was handed a report which indicated Maniu's alleged contacts with de Chastelain as proof that the politician was a British spy.

Reportedly, Cpt. Meţianu visited Romania at least once during the Cold War and visited major Constantin C. Roșescu at home.

In 1989, Porter's book Operation Autonomous: With SOE In Wartime Romania was published by Chatto and Windus. The translation of this book in Romanian was published by Humanitas in 1991.
