Vincenzo Vinciguerra

Vincenzo Vinciguerra was an Italian neofascist militant, a member of Ordine Nuovo and Avanguardia Nazionale, who carried out the Peteano bombing on May 31, 1972, and whose subsequent confessions provided the most detailed firsthand account available of how the strategy of tension functioned operationally. He was sentenced to life imprisonment and remained incarcerated in Italy.¹

Early Political Activity and the Peteano Attack

Vinciguerra was active in the Italian neofascist milieu from the late 1960s, moving between Ordine Nuovo and Avanguardia Nazionale. He carried out the Peteano attack on May 31, 1972: a booby-trapped Fiat 500 left near the village of Peteano in Friuli, which killed three Carabinieri - Donato Poveromo, Franco Dongiovanni, and Silvio Bellini - when they opened the hood to investigate.¹

After the attack, Vinciguerra fled to Spain, where he was sheltered within the network of expatriate neofascists and their protectors. The Peteano investigation was deliberately misdirected by SID (Italian military intelligence), which falsified forensic reports to conceal that the explosive used was military-grade C4 from Gladio weapons caches. The original investigation attributed the bombing to the far left and led nowhere. Vinciguerra lived in Spain for several years before returning to Italy, where he surrendered voluntarily on September 20, 1979.¹

The 1984 Confessions

In 1984, facing a life sentence, Vinciguerra made a voluntary confession to the Peteano bombing and provided testimony that went significantly beyond an admission of personal responsibility. His account described a functioning network in which neofascist operatives provided deniable capacity for violent attacks while receiving operational support, weapons, and protection from prosecution through elements of Italian military intelligence.

His testimony was explicit: the attack had been carried out with the knowledge of elements of SID, using weapons from Gladio stay-behind caches, with the expectation of intelligence service protection afterward. He described the relationship between the neofascist groups and the intelligence services not as direction from above but as a structured symbiosis - the neofascists wanted to act; elements of the intelligence services wanted attacks that could be attributed to the left or that created justification for authoritarian measures; both parties understood the arrangement.¹

Vinciguerra was convicted of the Peteano bombing and received a life sentence.

Continued Testimony

After conviction, Vinciguerra continued to provide testimony and make public statements about the strategy of tension. His statements were unusual in the Italian context for their directness: he did not minimize his own actions, and he named the institutional relationships that had made his activities possible. His account of the Peteano attack's political logic - that it was intended to create fear and political conditions favorable to reaction - was consistent with the overall pattern of strategy of tension violence documented by the Commissione Stragi.²

Felice Casson's reinvestigation of the Peteano case beginning in 1984, which eventually uncovered the Gladio documents, built directly on Vinciguerra's testimony. The chain from Vinciguerra's confession to Casson's investigation to Andreotti's 1990 parliamentary disclosure constituted the primary path by which the Gladio network was exposed.¹
