«According to various sources, including ex-member of Ordine Nuovo Vincenzo Vinciguerra, ex-OSS officer Peter Tompkins (1995; 2005), and an official American history of couterintelligence (Rafalko 1998), Prince Junio Valerio Borghese, the Commander of the X MAS for the Republic of Salò, was one of the fascists who agreed to collaborate with the Americans and for this reason was saved from reprisal by the partisans. On the basis of the testimony of Carlo Digilio, Vinciguerra and others, as we saw, it was alleged that many members of Ordine Nuovo were in the pay of America intelligence structures. Among these were Carlo Digilio himself, Delfo Zorzi and Marcello Soffiati.
