At 17:00, Mussolini, escorted by agents of the "presidenziale", arrived at the Villa Savoia where the King was waiting for him. He brought a copy of the law of the Grand Council, the OdG Grandi, and the letter of Cianetti. The Duce tried to convince Victor Emmanuel that the OdG had no legal value and that many of its supporters had changed their minds. The King told him that the country was broken, and the situation required him to quit his post; the new President of the Council of Ministers would be Marshal Badoglio. Mussolini feared for his future, but the King assured him that he would personally take care of his security and that of his family. Victor Emmanuel accompanied him to the door where he met Captain Vigneri. The Duce went to his car, but Captain Vigneri told him to go to a nearby ambulance for his security. Mussolini said there was no need for that, but followed him to the ambulance where the policemen were waiting. The ambulance left the park and rushed through Rome until reaching the "Podgora" army barracks in Trastevere before ultimately being moved to the "Legnano" Carabinieri barracks in Prati. The Duce received a kind letter from Badoglio the same night, explaining the necessity of his custody and asking him where he wanted to be brought. Mussolini asked to go to his summer residence, the Rocca delle Caminate, in Romagna, and he wrote to Badoglio that he was gladly willing to help him and his government. A transfer to his summer residence was not an option, and two days later he was accompanied to Gaeta, where the corvette "Persefone" brought him to the island of Ponza. He was transferred to the island of La Maddalena, and finally to Campo Imperatore, where he remained until 12 September 1943 when a German commando unit led by Otto Skorzeny freed him.
