Built in the
Stabilimento Tecnico Triestino in
Trieste,
Fiume was
laid down on 29 April 1929, the first member of the class to be laid down. She was
launched nearly a year later on 27 April 1930, the same day as her
sister ship .
Fitting-out work lasted another year and a half, and the new cruiser was
commissioning into the
Regia Marina (Royal Navy) on 23 November 1931. In January 1935, tests with
autogyros were conducted aboard
Fiume; a wooden platform was built on the stern of the ship to support the aircraft. The experiments proved to be successful, although the autogyros themselves had very limited range and were unreliable.
Fiume took part in a lavish ceremony held for the visit of
Adolf Hitler, the dictator of
Nazi Germany, in May 1938. She and
Zara conducted a gunnery demonstration while Hitler and the dictator of Italy,
Benito Mussolini, observed from the
battleship .
World War II When Italy formally joined the
Second World War by declaring war on France and Britain on 10 June 1940,
Fiume was assigned to the 1st Division with
Zara and the four destroyers of the 9th Destroyer Flotilla. The unit was assigned to the 1st Squadron, under the command of Admiral
Inigo Campioni. Two days later,
Fiume and the rest of the 1st Division, along with the 9th Division, sortied in response to British attacks on Italian positions in
Libya. While they were at sea, the British
submarine unsuccessfully attacked
Fiume and her sister . On 6 July, a convoy left Naples, bound for North Africa; the following day, Italian reconnaissance reported a British cruiser squadron to have arrived in
Malta. The Italian naval high command therefore ordered the 1st Division and several other cruisers and destroyers to join the escort for the convoy. The battleships
Conte di Cavour and provide distant support. Two days later, the Italian fleet briefly clashed with the British
Mediterranean Fleet in an
inconclusive action off Calabria. In late September, the Italian fleet, including
Fiume, made a sweep for a British troop convoy from
Alexandria to Malta, but it made no contact with the British ships.
Fiume was present in the harbor at Taranto when the British fleet launched the nighttime carrier
strike on Taranto on the night of 11–12 November, but she was not attacked in the raid. Another attempt to intercept a British convoy in late November resulted in the
Battle of Cape Spartivento. The Italian fleet left port on 26 November and clashed with the British fleet the next day, in an engagement that lasted for about an hour. Campioni broke off the action because he mistakenly believed he was facing a superior force, the result of poor aerial reconnaissance. The British heavy cruiser
HMS Berwick was hit twice by 203 mm rounds during the engagement, either fired by
Fiume or her sister
Pola.
Battle of Cape Matapan The Italian fleet, now commanded by Admiral
Angelo Iachino, made another attempt to intercept a British convoy in late March 1941. The fleet was supported by the
Regia Aeronautica and the German
10th Air Corps. This operation resulted in the
Battle of Cape Matapan; early in the battle,
Fiume and the rest of the 1st Division were to the northeast of the rest of the Italian fleet, which had encountered the British to the southwest. The battleship was torpedoed by British aircraft and forced to withdraw during this phase of the battle. The 1st Division remained on the port side of the Italian fleet as it began its return to port to screen against another possible British attack. A second British airstrike later in the day failed to locate the retiring
Vittorio Veneto and instead torpedoed
Pola, which left the cruiser immobilized.
Fiume,
Zara, and four destroyers were detached to protect
Pola. The British fleet, centered on the battleships , , and , was at this point only away. Guided by radar, the British fleet closed in on the crippled
Pola in the darkness while
Fiume,
Zara, and the destroyers approached from the opposite direction. At 10:27, the searchlights aboard
Warspite, the leading British battleship, illuminated
Fiume at a range of , followed immediately by a salvo of six shells from her main battery; five struck
Fiume and caused serious damage. Her superfiring rear turret was blown overboard before a second salvo from
Warspite struck the ship. Shortly thereafter,
Valiant fired four 15-inch shells into
Fiume, causing further devastation.
Fiume, now a burning wreck, was spared further destruction as the British battleships turned their attention to
Zara.
Fiume fell out of line, listing badly to starboard, as
Zara was similarly hammered by 15-inch broadsides.
Fiume remained afloat for about 45 minutes before she capsized and sank stern first at 23:15. Two of the destroyers,
Alfieri and
Carducci, were also sunk, as were
Zara and
Pola. The action had lasted a mere three minutes. 812 men were lost with
Fiume, among them her commanding officer Capt. Giorgio Giorgis; the survivors were picked up by British destroyers on the following morning, Greek destroyers in the evening of 29 March and the Italian hospital ship
Gradisca between 31 March and 3 April. == Footnotes ==
