Italian battleship Giulio Cesare

Giulio Cesare was one of three Template:Sclass dreadnought battleships built for the Royal Italian Navy (Template:Lang) in the 1910s. Completed in 1914, she was little used and saw no combat during the First World War. The ship supported operations during the Corfu Incident in 1923 and spent much of the rest of the decade in reserve. She was rebuilt between 1933 and 1937 with more powerful guns, additional armor and considerably more speed than before.

During World War II, both Giulio Cesare and her sister ship, Template:Ship, participated in the Battle of Calabria in July 1940, when the former was lightly damaged. They were both present when British torpedo bombers attacked the fleet at Taranto in November 1940, but Giulio Cesare was not damaged. She escorted several convoys to North Africa and participated in the Battle of Cape Spartivento in late 1940 and the First Battle of Sirte in late 1941. She was designated as a training ship in early 1942, and escaped to Malta after the Italian armistice the following year. The ship was transferred to the Soviet Union in 1949 and renamed Novorossiysk (Template:Lang). The Soviets also used her for training until she was sunk in 1955, with the loss of 617 men, by an explosion most likely caused by an old German mine. She was salvaged the following year and later scrapped.

Description

The Conte di Cavour class was designed to counter the French Template:Sclass dreadnoughts which caused them to be slower and more heavily armored than the first Italian dreadnought, Template:Ship.<ref>Giorgerini, p. 269</ref> The ships were Template:Convert long at the waterline and Template:Convert overall. They had a beam of Template:Convert, and a draft of Template:Convert.<ref name=randal259>Fracaroli, p. 259</ref> The Conte di Cavour-class ships displaced Template:Convert at normal load, and Template:Convert at deep load. They had a crew of 31 officers and 969 enlisted men.<ref name=g012>Giorgerini, pp. 270, 272</ref> The ships were powered by three sets of Parsons steam turbines, two sets driving the outer propeller shafts and one set the two inner shafts. Steam for the turbines was provided by 24 Babcock & Wilcox boilers, half of which burned fuel oil and the other half burning both oil and coal. Designed to reach a maximum speed of Template:Convert from Template:Convert, Giulio Cesare failed to reach this goal on her sea trials, reaching only Template:Convert from Template:Convert. The ships carried enough coal and oil<ref>Giorgerini, pp. 268, 272</ref> to give them a range of Template:Convert at Template:Convert.<ref name=randal259/>

Armament and armor

Layout of the main armament

The main battery of the Conte di Cavour class consisted of thirteen 305-millimetre Model 1909 guns, in five Template:Nautical term gun turrets, with a twin-gun turret superfiring over a triple-gun turret in fore and aft pairs, and a third triple turret amidships.<ref name=hore175>Hore, p. 175</ref> Their secondary armament consisted of eighteen Template:Convert guns mounted in casemates on the sides of the hull. For defense against torpedo boats, the ships carried fourteen [[QF 14 pounder naval gun Mk I & II naval gun|Template:Convert guns]]; thirteen of these could be mounted on the turret tops, but they could be positioned in 30 different locations, including some on the forecastle and upper decks. They were also fitted with three submerged Template:Convert torpedo tubes, one on each broadside and the third in the stern.<ref>Giorgerini, pp. 268, 277–278</ref>

The Conte di Cavour-class ships had a complete waterline armor belt that had a maximum thickness of Template:Convert amidships, which reduced to Template:Convert towards the stern and Template:Convert towards the bow. They had two armored decks: the main deck was Template:Convert thick on the flat that increased to Template:Convert on the slopes that connected it to the main belt. The second deck was Template:Convert thick. Frontal armor of the gun turrets was Template:Convert in thickness and the sides were Template:Convert thick. The armor protecting their barbettes ranged in thickness from Template:Convert. The walls of the forward conning tower were 280 millimetres thick.<ref>Giorgerini, pp. 270–272</ref><ref>McLaughlin, p. 421</ref>

Modifications and reconstruction

Office of Naval Intelligence drawing of the Conte di Cavour class, January 1943

Shortly after the end of World War I, the number of 76.2 mm guns was reduced to 13, all mounted on the turret tops, and six new 76.2-millimeter anti-aircraft (AA) guns were installed abreast the aft funnel. In addition two license-built [[QF 2 pounder naval gun|2-pounder (Template:Cvt)]] AA guns were mounted on the forecastle deck. In 1925–1926 the foremast was replaced by a four-legged (tetrapodal) mast, which was moved forward of the funnels,<ref name=g7>Giorgerini, p. 277</ref> the rangefinders were upgraded, and the ship was equipped to handle a Macchi M.18 seaplane mounted on the amidships turret. Around the same time, either one or both of the ships was equipped with a fixed aircraft catapult on the port side of the forecastle.<ref group="Note">Sources disagree if Giulio Cesare was fitted with a catapult or not. Giorgerini says both ships received one;<ref name=g7/> Whitley, Bagnasco & Grossman and Bargoni & Gay say that only Conte di Cavour received one.<ref name=w8>Whitley, p. 158</ref><ref name=eb4>Bagnasco & Grossman, p. 64</ref><ref>Bargoni & Gay, p. 18</ref></ref>

Giulio Cesare began an extensive reconstruction in October 1933 at the Cantieri del Tirreno shipyard in Genoa that lasted until October 1937.<ref name="Bargoni19">Bargoni & Gay, p. 19</ref> A new bow section was grafted over the existing bow which increased her length by Template:Convert to Template:Convert and her beam increased to Template:Convert. The ship's draft at deep load increased to Template:Convert.<ref name=eb4/> All of the changes made increased her displacement to Template:Convert at standard load and Template:Convert at deep load. The ship's crew increased to 1,260 officers and enlisted men.<ref>Brescia, p. 58</ref> Two of the propeller shafts were removed and the existing turbines were replaced by two Belluzzo geared steam turbines rated at Template:Convert.<ref name=eb4/> The boilers were replaced by eight Yarrow boilers. On her sea trials in December 1936, before her reconstruction was fully completed, Giulio Cesare reached a speed of Template:Convert from Template:Cvt.<ref>McLaughlin 2003, p. 422</ref> In service her maximum speed was about Template:Convert and she had a range of Template:Convert at a speed of Template:Convert.<ref>Bagnasco & Grossman, pp. 64–65</ref>

The main guns were bored out to [[320 mm Model 1934 naval gun|Template:Convert]] and the center turret and the torpedo tubes were removed. All of the existing secondary armament and AA guns were replaced by a dozen 120 mm guns in six twin-gun turrets and eight [[Škoda 10 cm K10#OTO 100.2F47 History|Template:Convert]] AA guns in twin turrets. In addition the ship was fitted with a dozen Breda [[Cannone-Mitragliera da 37/54 (Breda)|Template:Convert]] light AA guns in six twin-gun mounts and twelve [[Breda Model 1931 Machine Gun|Template:Convert Breda M31 anti-aircraft]] machine guns, also in twin mounts.<ref name=eb5>Bagnasco & Grossman, p. 65</ref> In 1940 the 13.2 mm machine guns were replaced by [[Breda Model 35|Template:Convert]] AA guns in twin mounts. Giulio Cesare received two more twin mounts as well as four additional 37 mm guns in twin mounts on the forecastle between the two turrets in 1941.<ref name=w8/> The tetrapodal mast was replaced with a new forward conning tower, protected with Template:Convert thick armor.<ref name="Bargoni21">Bargoni & Gay, p. 21</ref> Atop the conning tower there was a fire-control director fitted with two large stereo-rangefinders, with a base length of Template:Convert.<ref name="Bargoni21"/>

The deck armor was increased during the reconstruction to a total of Template:Convert over the engine and boiler rooms and Template:Convert over the magazines, although its distribution over three decks, meant that it was considerably less effective than a single plate of the same thickness. The armor protecting the barbettes was reinforced with Template:Convert plates.<ref name=m12/> All this armor weighed a total of Template:Convert.<ref name=w8/> The existing underwater protection was replaced by the Pugliese torpedo defense system that consisted of a large cylinder surrounded by fuel oil or water that was intended to absorb the blast of a torpedo warhead. It lacked, however, enough depth to be fully effective against contemporary torpedoes. A major problem with the reconstruction was that the ship's increased draft meant that the waterline armor belt was almost completely submerged with any significant load.<ref name=m12>McLaughlin 2003, pp. 421–22</ref>

Construction and service

Launch of Giulio Cesare, 15 October 1911.

Giulio Cesare, named after Julius Caesar,<ref>Silverstone, p. 298</ref> was laid down at the Gio. Ansaldo & C. shipyard in Genoa on 24 June 1910 and launched on 15 October 1911. She was completed on 14 May 1914 and served as a flagship in the southern Adriatic Sea during World War I.<ref name=s7>Preston, p. 176</ref> She saw no action, however, and spent little time at sea.<ref name=g7/> Admiral Paolo Thaon di Revel, the Italian naval chief of staff, believed that Austro-Hungarian submarines and minelayers could operate too effectively in the narrow waters of the Adriatic.<ref name="Halpern, p. 150">Halpern, p. 150</ref> The threat from these underwater weapons to his capital ships was too serious for him to use the fleet in an active way.<ref name="Halpern, p. 150"/> Instead, Revel decided to implement a blockade at the relatively safer southern end of the Adriatic with the battle fleet, while smaller vessels, such as the MAS torpedo boats, conducted raids on Austro-Hungarian ships and installations. Meanwhile, Revel's battleships would be preserved to confront the Austro-Hungarian battle fleet in the event that it sought a decisive engagement.<ref>Halpern, pp. 141–142</ref>

Giulio Cesare shortly after completion, 1914

Giulio Cesare made port visits in the Levant in 1919 and 1920. Both Giulio Cesare and Conte di Cavour supported Italian operations on Corfu in 1923 after an Italian general and his staff were murdered at the Greek–Albanian frontier; Benito Mussolini, who had been looking for a pretext to seize Corfu, ordered Italian troops to occupy the island. Cesare became a gunnery training ship in 1928, after having been in reserve since 1926. She was reconstructed at Cantieri del Tirreno, Genoa, between 1933 and 1937. Both ships participated in a naval review by Adolf Hitler in the Bay of Naples in May 1938 and covered the invasion of Albania in May 1939.<ref name=w1>Whitley, pp. 158–61</ref>

World War II

Early in World War II, the ship took part in the Battle of Calabria (also known as the Battle of Punta Stilo), together with Conte di Cavour, on 9 July 1940, as part of the 1st Battle Squadron, commanded by Admiral Inigo Campioni, during which she engaged major elements of the British Mediterranean Fleet. The British were escorting a convoy from Malta to Alexandria, while the Italians had finished escorting another from Naples to Benghazi, Libya. Admiral Andrew Cunningham, commander of the Mediterranean Fleet, attempted to interpose his ships between the Italians and their base at Taranto. Crew on the fleets spotted each other in the middle of the afternoon and the battleships opened fire at 15:53 at a range of nearly Template:Convert. The two leading British battleships, Template:HMS and Template:HMS, replied a minute later. Three minutes after she opened fire, shells from Giulio Cesare began to straddle Warspite which made a small turn and increased speed, to throw off the Italian ship's aim, at 16:00. Some rounds fired by Giulio Cesare overshot Warspite and near-missed the destroyers HMS Decoy and Hereward, puncturing their superstructures with splinters. At that same time, a shell from Warspite struck Giulio Cesare at a distance of about Template:Convert. The shell pierced the rear funnel and detonated inside it, blowing out a hole nearly Template:Convert across. Fragments started several fires and their smoke was drawn into the boiler rooms, forcing four boilers off-line as their operators could not breathe. This reduced the ship's speed to Template:Convert. Uncertain how severe the damage was, Campioni ordered his battleships to turn away in the face of superior British numbers and they successfully disengaged.<ref>O'Hara, pp. 28–35</ref> Repairs to Giulio Cesare were completed by the end of August and both ships unsuccessfully attempted to intercept British convoys to Malta in August and September.<ref>Whitley, p. 161</ref>

On the night of 11 November 1940, Giulio Cesare and the other Italian battleships were at anchor in Taranto harbor when they were attacked by 21 Fairey Swordfish torpedo bombers from the British aircraft carrier Template:HMS, along with several other warships. One torpedo sank Conte di Cavour in shallow water, but Giulio Cesare was not hit during the attack.<ref>Cernuschi & O'Hara, p. 81</ref> She participated in the Battle of Cape Spartivento on 27 November 1940, but never got close enough to any British ships to fire at them. The ship was damaged in January 1941 by splinters from a near miss during an air raid on Naples by Vickers Wellington bombers of the Royal Air Force; repairs at Genoa were completed in early February. On 8 February, she sailed from to the Straits of Bonifacio to intercept what the Italians thought was a Malta convoy, but was actually a raid on Genoa. She failed to make contact with any British forces. She participated in the First Battle of Sirte on 17 December 1941, providing distant cover for a convoy bound for Libya, and briefly engaging the escort force of a British convoy. She also provided distant cover for another convoy to North Africa in early January 1942.<ref>Whitley, pp. 161–162</ref> Giulio Cesare was reduced to a training ship afterwards at Taranto and later Pola.<ref name=b9>Brescia, p. 59</ref> After the Italian surrender on 8 September 1943, she steamed to Taranto, putting down a mutiny and enduring an ineffective attack by five German aircraft en route. She then sailed for Malta where she arrived on 12 September to be interned. The ship remained there until 17 June 1944 when she returned to Taranto where she remained for the next four years.<ref name=w2>Whitley, p. 162</ref><ref>Bargoni & Gay, p. 71</ref>Template:Refn

Soviet service

Novorossiysk at anchor, flying the Soviet jack

After the war, Giulio Cesare was allocated to the Soviet Union as part of war reparations. She was moved to Augusta, Sicily, on 9 December 1948, where an unsuccessful attempt was made at sabotage. The ship was stricken from the naval register on 15 December and turned over to the Soviets on 6 February 1949 under the temporary name of Z11 in Vlorë, Albania.<ref name=w2/> She was renamed Novorossiysk, after the Soviet city of that name on the Black Sea. The Soviets used her as a training ship, and gave her eight refits. In 1953, all Italian light AA guns were replaced by eighteen 37 mm 70-K AA guns in six twin mounts and six singles. Also replaced were her fire-control systems and radars. This was intended as a temporary rearmament, as the Soviets drew up plans to replace her secondary 120 mm mounts with the 130 mm/58 SM-2 that was in development, and the 100 mm and 37 mm guns with 8 quadruple 45 mm.<ref>Template:Cite journal</ref> While at anchor in Sevastopol on the night of 28/29 October 1955, an explosion ripped a Template:Convert hole in the forecastle forward of 'A' turret. The flooding could not be controlled, and she capsized with the loss of 617 men, including 61 men sent from other ships to assist.<ref>Karzhavin, B. A. (1991) "Личный состав", p. 244 in Тайна гибели линкора "Новороссийск". Документальная историческая хроника. Politekhnika. p. 244. Template:ISBN</ref>

The cause of the explosion is still unclear. The official cause, regarded as the most probable, was a magnetic RMH or LMB bottom mine, laid by the Germans during World War II and triggered by the dragging of the battleship's anchor chain before mooring for the last time. Subsequent searches located 32 mines of these types, some of them within Template:Convert of the explosion. The damage was consistent with an explosion of Template:Convert of TNT, and more than one mine may have detonated. Other explanations for the ship's loss have been proposed, and the most popular of these is that she was sunk by Italian frogmen of the wartime special operations unit Decima Flottiglia MAS who – more than ten years after the cessation of hostilities – were either avenging the transfer of the former Italian battleship to the USSR or sinking it on behalf of NATO.<ref name=m23>McLaughlin 2003, p. 423</ref><ref>McLaughlin 2007, pp. 142–52</ref><ref>Template:Cite journal</ref><ref>Template:Cite web</ref><ref>Greene & Massignani, pp. 195–98</ref> Novorossiysk was stricken from the naval register on 24 February 1956, salvaged on 4 May 1957, and subsequently scrapped.<ref name=m23/>
