On 2 and 8 June, they were received in audience by the King where they pressed for the arrest of Mussolini and the nomination of a military government, but they were left frustrated by the monarchical inaction.[31][32][33] On 30 June, Bonomi met Crown Prince Umberto and proposed three generals (Ambrosio, Marshal Pietro Badoglio and Enrico Caviglia) as Mussolini's potential successors.[34] On 4 July, Badoglio was received by Umberto, who implied that the Crown was no longer opposed to a change in government.[35] The following day, Ambrosio proposed that the King appoint Badoglio or Caviglia to head any government that replaced Mussolini.[36][37] Caviglia, a high-ranking freemason, was considered too old for such a difficult task despite his anti-fascist stance.[38] Badoglio, who resigned as Chief of the General Staff after the Greece debacle in 1941, had become a bitter enemy of Mussolini and wanted revenge.
