Augusto Riboty was one of three Mirabello-class scout cruisers built for the Italian Regia Marina (Royal Navy) during World War I.

She was in commission from 1917 to 1950, taking part in the Adriatic Campaign of World War I, and during the interwar period she was at Split during postwar unrest there.

[2] The ships carried enough fuel oil to give them a range of 2,300 nautical miles (4,300 km; 2,600 mi) at a speed of 12 knots (22 km/h; 14 mph).

[3] Augusto Riboty's main battery consisted of a single Cannone da 152 mm (6 in)/40 A Modello 1891 gun forward of the superstructure.

After getting underway from Brindisi on 4 November, Augusto Riboty arrived at the island of Lastovo (known to the Italians as Lagosta) at 14:00 that day and took possession of it for the Kingdom of Italy.

As the Italian consul Marcello Roddolo, serving aboard Augusto Riboty, observed, "Our troops, who are gradually occupying the borders of the [territory promised to Italy after the] armistice, and therefore are approaching Split, make the Yugoslavs believe that our occupation of that land [i.e., Split itself] is imminent, an occupation which the Serbian units would almost certainly oppose with weapons.

"[13] After the protected cruiser Puglia arrived to relieve her on station, Augusto Riboty departed Split on 12 January 1919, thus missing the worst of the violence there, which lasted until 1920.

Her growing obsolescence — her maximum speed had dropped to 27 knots (50 km/h; 31 mph), and she lacked a fire-control center[15] — led the Regia Marina to make plans to decommission her by 1940.

Tasked with occupying Corfu, the force, commanded by Ammiraglio di squadra (Squadron Admiral) Vittorio Tur, also included the light cruiser Bari (Tur's flagship), the light cruiser Taranto, the torpedo boats Altair, Andromeda, Angelo Bassini, Antares, Aretusa, Giacomo Medici, and Nicola Fabrizi, and the tankers Garigliano, Sesia, and Tirso.

[17][18] On 18 December 1940, as the Greco-Italian War continued, Augusto Riboty, the light cruisers Eugenio di Savoia and Raimondo Montecuccoli, and the destroyers Antonio Pigafetta, Emanuele Pessagno, and Nicoloso da Recco bombarded Greek positions near Corfu.

On the morning of 12 September 1943, Augusto Riboty and the submarines Atropo, Jalea, and Fratelli Bandiera got underway from Taranto and headed for Malta.

Augusto Riboty reached Malta on 13 September, moored at St. Paul's Bay that afternoon, and handed herself over to the Allies[22] in accordance with the armistice agreement.

On 6 October 1943 she left Malta with the torpedo boats Ariete and Orione, six submarines, and two smaller vessels to return to Italy.

[23] Augusto Riboty subsequently fought on the Allied side as a unit of the Italian Co-belligerent Navy through the end of World War II in Europe in May 1945.

She escorted U.S. convoys and took part in the transportation of men and materials to the battleships Italia and Vittorio Veneto, which were interned in the Great Bitter Lake in the Suez Canal in Egypt.

[9] Credited with participation in 365 operations and having steamed 70,350 nautical miles (130,288 km; 80,957 mi), Augusto Riboty was the most active Italian destroyer of World War II.
