''Vettor Pisani'', and in August 1940 was in command of submarine
''Sciré'', which was modified to carry the new secret Italian weapon, the
human torpedo. Known as "slow speed torpedoes" (''siluri a lenta corsa'', or SLC), and nicknamed "pigs" (''maiali'') for their poor maneuverability, these were small underwater assault vehicles with a crew of two.
These were part of the ''1ª Flottiglia Mezzi d'Assalto'' (MAS), the "First Assault Vehicle Flotilla" (later called ''
Decima Flottiglia MAS''), an elite naval sabotage unit of the Royal Italian Navy (''
Regia Marina Italiana'').
As commander of ''Sciré'' Borghese took part in several raids using SLC. The first of these, in September and October 1940,
were directed at Gibraltar. The September raid was abandoned when the harbour was found to be empty. In the October raid, Borghese took ''
Sciré'' deep into
Gibraltar Bay, making a difficult submerged passage in order to release the SLC as close to the target as possible. For this he received the
Medaglia d'Oro al Valor Militare (MOVM), despite the mission's overall lack of success.
In May 1941 a further attempt ended in failure, but on 20 September 1941, a successful mission damaged three merchant ships in the harbour. After this last attack, he was promoted to ''Capitano di Fregata'', and named commander of the ''Decima MAS sub-surface unit.
On 18 December 1941, he reached

Political activism after the war
With his record as a war hero and his support of Fascism, he became a figurehead for pro-fascist, anti-communist groups in the immediate post-war period, acquiring the nickname ''Black Prince''.
Borghese wrote a supportive introduction, affirming his political ideology of an idealistic
neo-fascist new aristocracy meritocratically based purely on character, to
far right revolutionary-conservative theorist
Julius Evola's book ''
Men Among the Ruins'
He later wrote a memoir of his wartime exploits, published as ''Sea Devils'' in 1954. He was associated with the

Golpe Borghese, he was forced to cross the border to avoid arrest and interrogation. In 1984, ten years after Borghese's death, the
Supreme Court of Cassation ruled that no ''coup d'état'' attempt had happened, in the sense that it was just a "meeting of four or five sixty-year-olds".

Nevertheless, the attempt is well known in Italy and film director

Final years and death
Latterly regarded as a political outcast and shunned by his ancestrally
blue blood social connections for his "heretical" political extremism and disregard for the external norms of modern aristocratic etiquette and behaviour, Borghese died under mysterious circumstances in

, Spain, on 26 August 1974, aged 68. The death certificate records the cause of death as "
acute hemorrhagic pancreatitis"; however, since Borghese was visited by a physician who found him in good shape just a few days before, it has been suggested that the circumstances of his death, characterized by a sudden onset of abdominal pain immediately after supper, could be compatible with
arsenic poisoning.
He is buried in the Borghese family chapel in the
Basilica di Santa Maria Maggiore, Rome.
