They include: In 1919, he joined as a volunteer in the capture of Fiume by d'Annunzio, and was placed by the latter at the helm of the 'Fleet of Carnaro', and he operated providing food to the city, until the start of 1920.

The following year he founded Calatimbar in Genoa, a company of shipowners, exporters and shippers, which was intended to board all goods departing from that port.

On 10 June 1940, at Italy's entry into World War II, he asked to return to active duty and he dealt with the anti-submarine warfare in the Sicilian Channel; he was discharged from service in January 1941, assuming the post of President of Lloyd Triestino.

On 20 February 1942, he was appointed President of the Adriatic Shipyards; after the Italian armistice on 8 September 1943, he ordered the sabotage of ocean liners and steamers so that they would not fall into German hands.

For this initiative, he was transferred by the Gestapo to Austria, first to Klagenfurt prison and later to the obligatory stay in Hirschegg, where he was reached by his daughter Maria Guglielmina.
