SMS Tegetthoff (His Majesty's Ship Tegetthoff)[lower-alpha 2] was the second of four Tegetthoff-class dreadnought battleships built for the Austro-Hungarian Navy. Tegetthoff was named for the 19th-century Austrian Admiral Wilhelm von Tegetthoff, most notable for defeating the Italian Regia Marina at the Battle of Lissa in 1866. The ship was armed with a main battery of twelve 30.5 cm (12.0 in) guns in four triple turrets. Constructed shortly before World War I, she was built at the Stabilimento Tecnico Triestino shipyard in Trieste, where she was laid down in September 1910 and launched in March 1912.

Tegetthoff was a member of the 1st Battleship Division of the Austro-Hungarian Navy at the beginning of the war alongside the other ships of her class, and was stationed out of the Austro-Hungarian naval base at Pola. First saw action during the Bombardment of Ancona following Italy's declaration of war on Austria-Hungary in May 1915, but saw little combat for the rest of the war due to the Otranto Barrage, which prohibited the Austro-Hungarian Navy from leaving the Adriatic Sea. In June 1918, in a bid to earn safer passage for German and Austro-Hungarian U-boats through the Strait of Otranto, the Austro-Hungarian Navy attempted to break the Barrage with a major attack on the strait, but it was abandoned after Tegetthoff and her sister ship, Szent István were attacked by Italian motor torpedo boats on the morning of 10 June. Tegetthoff was unharmed during the attack, but Szent István was sunk by torpedoes launched from MAS-15.

After the sinking of Szent István, Tegetthoff and the remaining two ships of her class returned to port in Pola where they remained for the rest of the war. When Austria-Hungary was facing defeat in the war in October 1918, the Austrian government decided to transfer the bulk of her navy to the newly formed State of Slovenes, Croats and Serbs in order to avoid having to hand the ship over to the Allies.[2] This transfer however was not recognized by the Armistice of Villa Giusti, signed between Austria-Hungary and the Allies in November 1918. Under the terms of the Treaty of Saint-Germain-en-Laye, Tegetthoff was handed over to Italy. She was subsequently moved to Venice before being shown as a war trophy by the Italians. During that time period she starred in the movie Eroi di nostri mari ("Heroes of our seas"), which depicted the sinking of Szent István. Following the adoption of the Washington Naval Treaty in 1922, she was broken up at La Spezia between 1924 and 1925.

Background

Before the construction of Tegetthoff and her namesake class, most of Austria-Hungary's previous battleships had been designed for the defense of the Empire's coastline.[3] During the 19th-century, sea power had not been a priority in Austrian foreign policy. As a result, the Austro-Hungarian Navy had little public interest or support. However, the appointment of Archduke Franz Ferdinand – heir to the Austro-Hungarian throne and a prominent and influential supporter of naval expansion – to the position of admiral in September 1902 greatly increased the importance of the navy in the eyes of both the general public and the Austrian and Hungarian Parliaments.[4][5] Franz Ferdinand's interest in naval affairs were largely motivated from his belief that a strong navy would be necessary to compete with Italy, which he viewed as Austria-Hungary's greatest regional threat.[6]

In 1904, the Austro-Hungarian Navy began an expansion program intended to equal that of the other Great Powers of Europe. This naval expansion program coincided with the establishment of the Austrian Naval League in September 1904 and the appointment of Vice-Admiral Rudolf Montecuccoli to the posts of Commander-in-Chief of the Navy (German: Marinekommandant) and Chief of the Naval Section of the War Ministry (German: Chef der Marinesektion) in October that same year.[7][8] After Montecuccoli's appointment, the Admiral worked to pursued the efforts championed by his predecessor, Admiral Hermann von Spaun, and pushed for a greatly expanded and modernized navy.[9]

The origins of Tegetthoff and her namesake class can also be found in developments in the first decade of the 20th century which greatly increased the importance of sea power to the Austro-Hungarian Empire. Between 1906 and 1907, railroads linking Trieste and the Dalmatian coastline to the interior of the Empire had been constructed through Austria's Alpine passes. Additionally, lower tariffs on the port of Trieste allowed for a rapid expansion of the city and a similar growth in Austria-Hungary's merchant marine. As Austria-Hungary became more connected to naval affairs than in past decades, a new line of battleships would be necessary to match the Empire's growing naval interests.[3]

Tegetthoff was first envisioned in the middle of a heated naval arms race between Austria-Hungary and its nominal ally, Italy.[10][11] Since the Battle of Lissa in 1866, Italy's Regia Marina was considered the most-important naval power in the region which Austria-Hungary measured itself against, often unfavorably. The disparity between the Austro-Hungarian and Italian navies had existed since the unification of Italy; in the late 1880s Italy had the third-largest fleet in the world, behind the French Republic's Navy and the British Royal Navy.[12][13] While the disparity between Italian and Austro-Hungarian naval strength had been somewhat equalized with the Russian Imperial Navy and the German Kaiserliche Marine surpassing the Italian Navy in 1893 and in 1894,[12] Italy had once again regained the initiative by the turn of the century. In 1903, the year before Montecuccoli's appointment, Italy had 18 battleships in commission or under construction compared to 6 Austro-Hungarian battleships.[13]

Following the construction of the final two Regina Elena-class battleships in 1903, the Italian Navy elected to construct a series of large cruisers rather than additional battleships. Furthermore, a major scandal involving the Terni steel works' armor contracts led to a government investigation that postponed several naval construction programs for three years. These delays meant that the Italian Navy would not initiate construction on another battleship until 1909, and provided the Austro-Hungarian Navy an attempt to even the disparity between the two fleets.[5] The construction of Tegetthoff can thus be viewed in the context of the naval rivalry between Austria-Hungary and Italy, with the ship playing a role in a larger attempt by Austria-Hungary to compete with Italy's naval power.[6]

Austro-Italian naval arms race

The revolution in naval technology created by the launch of the British HMS Dreadnought in 1906 and the Anglo-German naval arms race that followed had a tremendous impact on the development of future battleships around the world, including Tegetthoff. Dreadnought, armed with ten large-caliber guns, was the first of a revolutionary new standard of "all-big-gun" battleships that rendered pre-dreadnought battleships obsolete. As a result, the value of older battleships declined rapidly in the years after 1906. This development gave Austria-Hungary the opportunity to make up for neglecting its navy in past years. Furthermore, Austria-Hungary's improved financial situation following the Austro-Hungarian Compromise of 1867 were beginning to reflect in the form of larger budgets being allocated to the Empire's armed forces. Political will also existed to construct Austria-Hungary's own dreadnought battleship, as both Archduke Ferdinand and Admiral Montecuccoli were supportive of constructing a new class of modern battleships. As a result, by 1908 the stage was set for the creation of Tegetthoff and her namesake class.[14][4]

Shortly after assuming command as Chief of the Navy, Montecuccoli drafted his first proposal for a modern Austrian fleet in the spring of 1905. While these plans were ambitious and included 12 battleships, none of the ships approached the eventual size of Tegetthoff.[14] Additional proposals came from outside the Naval Section of the War Ministry. Two proposals from Slovenian politician Ivan Šusteršič, and the Austrian Naval League in 1905 and 1909 included battleships which approached the size of Tegetthoff. While Šusteršič's plan lacked the large-caliber guns that would later be found on Tegetthoff, the plans submitted by the Austrian Naval League three dreadnoughts of 19,000 tonnes (18,700 long tons), similar to Tegetthoff's eventual displacement of 20,000 t (19,684 long tons). These plans were justified by the League by pointing out that newer battleships were necessary to protect Austria-Hungary's growing merchant marine, and that Italian naval spending was twice that of Austria-Hungary's.[15]

Following the construction of Austria-Hungary's last class of pre-dreadnought battleships, the Radetzky class,[16] Montecuccoli submitted a proposal which would include the first design for Tegetthoff.[17] With the threat of war with Italy from the Bosnian Crisis in 1908 fresh in the minds of the Austro-Hungarian military, Montecuccoli delivered a memorandum to Emperor Franz Joseph I in January 1909 proposing an enlarged Austro-Hungarian Navy consisting of 16 battleships, 12 cruisers, 24 destroyers, 72 seagoing torpedo boats, and 12 submarines. The most notable change in this memorandum compared to Monteccucoli's previous draft from 1905 was the inclusion of four additional dreadnought battleships with a displacement of 20,000 tonnes (19,684 long tons) at load. One of these ships would eventually become Tegetthoff.[18][19]

Plans and budget

Montecuccoli's memorandum would eventually be leaked to Italian newspapers just three months after obtaining approval from Emperor Franz Joseph I. The Italian reaction to the Austro-Hungarian plans was swift, and in June 1909, the Italian dreadnought battleship Dante Alighieri was laid down at the naval shipyard in Castellammare di Stabia.[18]

While Dante Alighieri was being worked on in Italy, Austria-Hungary's own plans for Tegetthoff and the other ships of her class remained on paper. Funding necessary to begin construction was not to be had either, due to the collapse of Sándor Wekerle's government in Budapest. This left the Hungarian Diet without a prime minister for nearly a year. With no government in Budapest to pass a budget, the money necessary to pay for Tegetthoff could not be obtained.[20] As a result, the largest shipbuilding enterprises in Austria-Hungary, the Witkowitz Ironworks and the Škoda Works, offered to begin construction on Tegetthoff and two other dreadnoughts at their own financial risk, in return for assurances that the Austro-Hungarian government would purchase the battleships as soon as funds were available. After negotiations which involved the Austro-Hungarian joint ministries of foreign affairs, war and finance, the offer was agreed to by Montecuccoli, but the number of dreadnoughts constructed under this arrangement was reduced to just Tegetthoff and Viribus Unitis.[21] In his memoirs, former Austrian Field Marshal and Chief of the General Staff Conrad von Hötzendorf wrote that due to his belief that a war with Italy in the near future was likely, construction on the battleships should begin as soon as possible. He also worked to secure agreements to sell both Tegetthoff and Viribus Unitis to, in his words, a "reliable ally" (which only Germany could claim to be) should the budget crisis in Budapest fail to be settled quickly.[22]

Outline

Although smaller than the contemporary dreadnought and super-dreadnought battleships of the German Kaiserliche Marine and the British Royal Navy, Tegetthoff was part of the first class of its type in the Mediterranean and Adriatic Seas.[23] Tegetthoff and her sister ships were described by former Austro-Hungarian naval officer Anthony Sokol in his book The Imperial and Royal Austro-Hungarian Navy as "excellent ships", and she was knowledged as one of the most powerful battleships in the region. The design of the battleship also signaled a change in Austro-Hungarian naval policy, as she was capable of far more than coastal defense or patrolling the Adriatic Sea.[23] Indeed, Tegetthoff and her sister ships were so well received that when the time came to plan for the replacement of Austria-Hungary's old Monarch-class coastal defense ships, the navy elected to simply take the layout of her class and enlarge them to have a slightly greater tonnage and larger main guns.[24]

Funding

The cost to construct Tegetthoff was enormous by the standards of the Austro-Hungarian Navy. While the Habsburg-class, Erzherzog Karl-class, and the Radetzky-class battleships cost the navy roughly 18, 26, and 40 million krone per ship,[25] Tegetthoff was projected to cost over 60 million krone.[26] Under the previous budgets for 1907 and 1908, the navy had been allocated some 63.4 and 73.4 million krone, which at the time was considered an inflated budget due to the construction of two Radetzkys. Montecuccoli worried that the general public and the legislatures in Vienna and Budapest would reject the need for a ship as expensive as Tegetthoff, especially so soon after the political crisis in Budapest. The dramatic increase in spending meant that in 1909 the navy spent some 100.4 million krone, a huge sum at the time. This was done in order to rush the completion of the Radetzky-class battleships, though the looming construction of three other dreadnoughts in addition to Tegetthoff meant the Austro-Hungarian Navy would likely have to ask the government for a yearly budget much higher than 100 million krone.[25] In order to guarantee funding for the ship from the Rothschild family in Austria, who owned the Witkowitz Ironworks, the Creditanstalt Bank, and had significant assets in both the Škoda Works and the Stabilimento Tecnico Triestino, Archduke Franz Ferdinand personally courted Albert Salomon Anselm von Rothschild to obtain his family's monetary support until the government could buy the battleship.[27][28]

Facing potential backlash over constitutional concerns that the construction of Tegetthoff committed Austria-Hungary to spend roughly 60 million Kronen without prior approval by either the Austrian Reichsrat or the Diet of Hungary, the deal remained secret.[29] In the event of the agreement being leaked to the press prior to the passage of a new naval budget, Montecuccoli drafted several explanations to justify construction of the battleship and the necessity to keep its existence a secret. These included the navy's urgent need to counter Italy's naval build up and desire to negotiate a lower price with their builders.[25] By the time the agreement was leaked to the public in April 1910 by the Arbeiter-Zeitung, the newspaper of Austria's Social Democratic Party, the plans had already been finalized and construction on Tegetthoff was about to begin.[10]

General characteristics

Designed by naval architect Siegfried Popper,[30][10] Tegetthoff had an overall length of 152 metres (498 ft 8 in), with a beam of 27.90 metres (91 ft 6 in) and a draught of 8.70 metres (28 ft 7 in) at deep load. She was designed to displace 20,000 tonnes (19,684 long tons; 22,046 short tons) at load, but at full combat load she displaced 21,689 tonnes (21,346 long tons; 23,908 short tons).[1] Tegetthoff's hull was built with a double bottom, 1.22 metres (4 ft 0 in) deep, with a reinforced inner bottom that consisted of two layers of 25-millimetre (1 in) plates.[1]

The hull design was intended by Popper to protect the battleship from naval mines, though it ultimately failed Tegetthoff's sister ships, Szent István and Viribus Unitis, when the former was sunk by a torpedo in June 1918 and the latter by a mine in November of that same year.[31] Tegetthoff also featured two 2.74-metre (9 ft 0 in) Barr and Stroud optical rangefinder posts on both the starboard and port sides for the secondary guns of the battleship. These rangefinders were equipped with an armored cupola.[1] Tegetthoff was equipped with torpedo nets,[1] though they were removed in June 1917.[32]

Propulsion

Turbines of Tegetthoff

Tegetthoff possessed four shafts and four Parsons steam turbines, which were housed in a separate engine-room and powered by twelve Babcock & Wilcox boilers. They were designed to produce a total of 26,400 or 27,000 shaft horsepower (19,686 or 20,134 kW), which was theoretically enough to attain a maximum designed speed of 20 knots (37 km/h; 23 mph). It was reported during her speed trials that she attained a top speed of 19.75 knots (36.58 km/h; 22.73 mph),[33] though her actual top speed is unknown as the official sea trial data and records for all ships of the Tegetthoff class were lost after the war.[1] Tegetthoff also carried 1,844.5 tonnes (1,815.4 long tons; 2,033.2 short tons) of coal, and an additional 267.2 tonnes (263.0 long tons; 294.5 short tons) of fuel oil that was to be sprayed on the coal to increase its burn rate.[1] At full capacity, Tegetthoff could steam for 4,200 nautical miles (7,800 km; 4,800 mi) at a speed of 10 knots (19 km/h; 12 mph).[34]

Armament

Constructed at the Škoda Works in Plzeň, Bohemia, Tegetthoff's main battery consisted of twelve 45-calibre 30.5-centimetre (12 in) Škoda K10 guns mounted in four triple turrets. Two turrets each were mounted forward and aft of the ship's main superstructure in a superfiring pair. The implementation of triple turrets aboard Tegetthoff came about for two reasons: the need to ensure the ship had a more-compact design and smaller displacement to conform to Austro-Hungarian naval doctrine and budget constraints, and to counter the implementation of triple turrets on the Italian Dante Alighieri.[35]

Having three guns on each turret rather than two made it possible to deliver a heavier broadside than other dreadnoughts of a similar size and meant a shorter citadel and better weight distribution. The choice of implementing triple turrets also assisted in the construction speed of Tegetthoff as well. The guns for the battleship were available at short notice because Škoda had already been working on a triple-turret design ordered by the Imperial Russian Navy when their initial order for Tegetthoff's armament arrived.[36]

Tegetthoff carried a secondary armament which consisted of a dozen 50-calibre 15-centimetre (5.9 in) Škoda K10 guns mounted in casemates amidships. Additionally, eighteen 50-calibre 7-centimetre (2.8 in) Škoda K10 guns were mounted on open pivot mounts on the upper deck, above the casemates. Three more 7-centimetre (2.8 in) Škoda K10 guns were mounted on the upper turrets for anti-aircraft duties. Two additional 8-millimetre (0.31 in) Schwarzlose M.07/12 anti-aircraft machine guns were mounted atop the armored cupolas of her rangefinders. Tegetthoff was also equipped with two 7-centimetre (2.8 in) Škoda G. L/18 landing guns, and two 47-millimetre (1.9 in) Škoda SFK L/44 S guns for use against small and fast vessels such as torpedo boats and submarines. Furthermore, she also fitted with four 533-millimetre (21.0 in) submerged torpedo tubes, one each in the bow, the stern, and each side. Complementing these torpedo tubes, Tegetthoff usually carried twelve torpedoes.[1]

Armor

Tegetthoff was protected at the waterline with an armor belt which measured 280 millimetres (11 in) thick in the central citadel, where the most-important parts of the ship were located. This armor belt was located between the midpoints of the fore and aft barbettes, and thinned to 150 millimetres (5.9 in) further towards the bow and stern, but did not reach either. It was continued to the bow by a small patch of 110–130-millimetre (4–5 in) armor. The upper armor belt had a maximum thickness of 180 millimetres (7.1 in), but it thinned to 110 millimetres (4.3 in) from the forward barbette all the way to the bow. The casemate armor was also 180 millimetres (7.1 in) thick.[37]

The sides of the main gun turrets, barbettes, and main conning tower were protected by 280 millimetres (11 in) of armor, except for the turret and conning tower roofs which were 60 to 150 millimetres (2 to 6 in) thick. The thickness of the decks ranged from 30 to 48 millimetres (1 to 2 in) in two layers. The underwater protection system consisted of the extension of the double-bottom upwards to the lower edge of the waterline armor belt, with a thin 10-millimetre (0.4 in) plate acting as the outermost bulkhead. It was backed by a torpedo bulkhead that consisted of two 25-millimetre plates.[37] The total thickness of this system was only 1.60 metres (5 ft 3 in) which made Tegetthoff incapable of containing a torpedo warhead detonation or mine explosion without rupturing.[38] This design flaw would ultimately prove to be fatal to her sister ships Szent István and Viribus Unitis.[38]

Construction

Montecuccoli's plans for the construction of Tegetthoff and her sister ships earned the approval of Emperor Franz Joseph I in January 1909, and by April plans for the design, construction, and financing for Tegetthoff was laid out.[18] For a full year, the Austro-Hungarian Navy attempted to keep the looming construction of Tegetthoff and Viribus Unitis a state secret. This did not prevent rumors from circulating across Europe of two dreadnought battleships being constructed in Austria-Hungary. The French Naval Attaché in Vienna complained to Paris in 1910 of extensive secrecy within the Austro-Hungarian Navy, which manifested itself in several ways. Among these were a ban on photography in the Pola, future home port of Tegetthoff, and near-constant observation by the Austro-Hungarian police.[39]

The British Admiralty considered the rumored construction of Tegetthoff and Viribus Unitis "as a concealed addition to the German fleet", and interpreted the ships as Austria-Hungary's way of repaying Germany for her diplomatic support during the former's annexation of Bosnia in 1908.[40] During the spring and summer of 1909, the United Kingdom was locked in a heated naval arms race with Germany which led the Royal Navy to look upon the battleship as a ploy by German Grand Admiral Alfred von Tirpitz to outpace British naval construction, rather than the latest development in Austria-Hungary's own naval arms race with Italy. The Admiralty's concerns regarding the true purpose of Tegetthoff was so great that a British spy was dispatched to Berlin when Montecuccoli sent an officer from the Naval Section of the War Ministry to obtain recommendations from Tirpitz regarding the design and layout of the battleship.[41] These concerns continued to grow and in April 1909, British Ambassador Fairfax Leighton Cartwright asked Austro-Hungarian Foreign Minister Alois Lexa von Aehrenthal about the rumored battleships. Aehrenthal denied the construction of the Tegetthoff and Viribus Unitis, but admitted that plans to construct a class of dreadnoughts were being considered. In an attempt to assure Cartwright that Austria-Hungary was not constructing any ships for the German Navy, Aehrenthal justified any naval expansion as being necessary to secure Austria-Hungary's strategic interests in the Mediterranean. At the time, the potential that Austria-Hungary was constructing a class of dreadnought battleships was widely regarded among the British press, public, and politicians as a provocation on the part of Germany.[42] Neither the Admiralty's suspicions, nor those of some politicians, managed to convince Parliament that the German government was attempting to use Tegetthoff and Viribus Unitis to escalate Germany and Britain's already contentious naval arms race however. When Winston Churchill was appointed First Lord of the Admiralty in 1911, he rejected any potential Austro-German collusion regarding the battleship.[43]

Roughly a year after Tegetthoff's plans were drafted, Arbeiter-Zeitung, the Austrian Social Democratic Party newspaper, reported the details of the battleship to the general public.[44] The Christian Social Party, supportive of the construction of Tegetthoff and her sister ships, and operating on the advice of the navy, published in its own newspaper, Reichspost, that the secret project to construct the battleship and the related financial agreements to fund it were true. The Reichspost lobbied in support of the project, citing Austria-Hungary's national security concerns with an Italian dreadnought already under construction. When the story broke, Archduke Ferdinand also worked to build public support for the construction of Tegetthoff, and the Austrian Naval League did the same.[10][45]

Tegetthoff, the title ship of her class, was laid down in Trieste by Stabilimento Tecnico Triestino on 24 September 1910, once it became clear that Vienna and Budapest would pass the necessary budget to fund the construction of the entire class. The budgets were approved after two meetings of the Austrian Reichsrat and the Diet of Hungary in October and November 1910, opposition being rejected as the Italian Navy had laid down another three battleships during the summer.[46][10]

The final package of the budget agreement which funded Tegetthoff included provisions which ensured that while the armor and guns of the battleship were to be constructed within Austria, the electrical wiring and equipment aboard Tegetthoff was to be assembled in Hungary. Additionally, half of all ammunition and shells for the guns of the ship would be purchased in Austria, while the other half was to be bought in Hungary.[47] Aside from a brief strike in Trieste in May 1911, construction on Tegetthoff continued at a fast pace. Less than a year after being laid down, Tegetthoff was launched on 21 March after delays due to poor weather around Trieste.[34][48]

Originally referred to as "Battleship V", discussion began over what to name the battleship while it was under construction in Trieste. The Naval Section of the War Ministry initially proposed naming the battleship Don Juan. Newspapers within Austria reported during construction that one of the ships was to be named Kaiser Franz Joseph I were unfounded as the Austro-Hungarian Navy had no intentions of renaming the cruiser which already bore the Emperor's name. Emperor Franz Joseph I ultimately decided the names of all four dreadnoughts, selecting to name the first ship after his own personal motto, Viribus Unitis (Latin: "With United Forces"), while the second ship would be named Tegetthoff, after Wilhelm von Tegetthoff, a 19th-century Austrian naval admiral known for his victory over Italy at the Battle of Lissa in 1866.[26] Tegetthoff was commissioned into the Austro-Hungarian Navy on 14 July 1913.[34] During her gunnery trials, a discharge from one of the ship's main guns damaged the staterooms of the ship's officers.[33][49]

Service history

Tegetthoff underway

Prior to World War I, Tegetthoff and her sister ship Viribus Unitis served as the pride of the Austro-Hungarian Navy, conducting several missions across the Adriatic and Mediterranean Seas as members of the First Battle Division under the command of Vice-Admiral Maximilian Njegovan.[50] In the spring of 1914 both ships, together with the pre-dreadnought battleship Zrínyi and the coastal defense ship Monarch, traveled the eastern Mediterranean and the Levant, visiting the ports of Smyrna, Beirut, Alexandria, and Malta.[51][52][53] Meanwhile, Tegetthoff and Viribus Unitis arrived at Malta on 22 May, before leaving for Pola on 28 May, exactly one month before Archduke Franz Ferdinand's assassination and two months before the start of the war.[54][52]

Upon hearing of the assassination of Archduke Franz Ferdinand and his wife Sophie on 28 June in Sarajevo, Commander-in-Chief of the Navy Anton Haus sailed south from Trieste with an escort fleet composed of Tegetthoff, the cruiser Admiral Spaun, and several torpedo boats. Two days after their murders, Ferdinand and Sophia's bodies were transferred aboard Viribus Unitis, which had been anchored off Bosnia waiting to receive the Archduke for his return. Tegetthoff and the other ships in Haus' fleet then escorted Viribus Unitis back to Trieste.[55] During the voyage, the fleet moved slowly along the Dalmatian coast and usually within sight of land. Coastal towns and villages rang church bells when the ships passed while spectators watched the fleet from the shoreline.[52] The Archduke's death triggered the July Crisis, culminating in Austria-Hungary's declaration of war on the Kingdom of Serbia on 28 July 1914.[56][50]

World War I

Outbreak of war

Events unfolded rapidly in the ensuing days. On 30 July 1914 Russia declared full mobilization in response to Austria-Hungary's declaration of war on Serbia. Austria-Hungary declared full mobilization the next day. On 1 August both Germany and France ordered full mobilization and Germany declared war on Russia in support of Austria-Hungary. While relations between Austria-Hungary and Italy had improved greatly in the two years following the 1912 renewal of the Triple Alliance,[57] increased Austro-Hungarian naval spending, political disputes over influence in Albania, and Italian concerns over the potential annexation of land in the Montenegro caused the relationship between the two allies to falter in the months leading up to the war.[58] Italy's declaration of neutrality in the war on 1 August dashed Austro-Hungarian hopes to use Tegetthoff in major combat operations in the Mediterranean, as the navy had been relying upon coal stored in Italian ports to operate in conjunction with the Regia Marina.[59] By 4 August, Germany had already occupied Luxembourg and invaded Belgium after declaring war on France, and the United Kingdom had declared war on Germany in support of Belgian neutrality.[60]

The assistance of the Austro-Hungarian fleet was called upon by the German Mediterranean Division, which consisted of the battlecruiser SMS Goeben and light cruiser SMS Breslau.[61] The German ships were attempting to break out of Messina, where they had been taking on coal prior to the outbreak of war. By the first week of August, British ships had begun to assemble off Messina in an attempt to trap the Germans. While Austria-Hungary had not yet fully mobilized its fleet, a force was assembled to assist the German ships. This consisted of Tegetthoff, Viribus Unitis, and Prinz Eugen, as well as three Radetzkys, the armoured cruiser Sankt Georg, the scout cruiser Admiral Spaun, six destroyers, and 13 torpedo boats.[62] The Austro-Hungarian high command, wary of instigating war with Great Britain, ordered the fleet to avoid the British ships and to only support the Germans openly while they were in Austro-Hungarian waters. On 7 August, when the Germans broke out of Messina, the Austro-Hungarian fleet had begun to sail for Brindisi to link up with the Germans and escort their ships to a friendly port in Austria-Hungary. However, the German movement toward the mouth of the Adriatic had been a diversion to throw the British and French off their pursuit, and the German ships instead rounded the southern tip of Greece and made their way to the Dardanelles, where they would eventually be sold to the Ottoman Empire. Rather than follow the German ships towards the Black Sea, the Austrian fleet returned to Pola.[63][64]

Following France and Britain's declarations of war on Austria-Hungary on 11 and 12 August respectively, the French Admiral Augustin Boué de Lapeyrère was issued orders to close off Austro-Hungarian shipping at the entrance to the Adriatic Sea and to engage any Austro-Hungarian ships his Anglo-French fleet came across. Lapeyrère chose to attack the Austro-Hungarian ships blockading Montenegro. The ensuing Battle of Antivari ended Austria-Hungary's blockade, and effectively placed the entrance of the Adriatic Sea firmly in the hands of Britain and France.[65][66]

After the breakout of Goeben and Breslau, Tegetthoff saw very little action, spending much of her time in port at Pola. The ship's lack of time spent at sea was part of a greater general inactivity among nearly all ships of the Austro-Hungarian Navy. This was partly caused by a fear of mines in the Adriatic,[67] though other factors contributed to the lack of naval activity. Haus was fearful that direct confrontation with the French Navy, even if it should be successful, would weaken the Austro-Hungarian Navy to the point that Italy would have a free hand in the Adriatic.[68] This concern was so great to Haus that he wrote in September 1914, "So long as the possibility exists that Italy will declare war against us, I consider it my first duty to keep our fleet intact."[69] Haus' decision to use the Austro-Hungarian Navy as a fleet in being earned sharp criticism from the Austro-Hungarian Army, the German Navy, and the Austro-Hungarian Foreign Ministry,[70] but it also led to a far greater number of Entente naval forces being devoted to the Mediterranean and the Strait of Otranto. These could have been used elsewhere, such as against the Ottoman Empire during the Gallipoli Campaign.[71]

The most-important factor contributing to Tegetthoff spending most of her time at port may have been the lack of coal. Prior to the war, the United Kingdom had served as Austria-Hungary's primary source for coal. In the years before the war an increasing percentage of coal had come from mines in Germany, Virginia, and from domestic sources, but 75% of the coal purchased for the Austro-Hungarian Navy came from Britain. The outbreak of war meant that these sources, as well as those from Virginia, would no longer be available. Significant quantities of coal had been stockpiled before the war however, ensuring the navy was capable of sailing out of port if need be. Even so, the necessity of ensuring that Tegetthoff had the coal she needed in the event of an Italian or French attack or a major offensive operation resulted in her and other battleships remaining at port unless circumstances necessitated their deployment at sea.[70][67]

In early 1915 Germany suggested that Tegetthoff and the other battleships of the Austro-Hungarian Navy conduct an attack on the Otranto Barrage in order to relieve pressure on the Ottoman Empire at the height of the Gallipoli Campaign. Haus, still weary of taking Austria-Hungary's battleships out of port, rejected the proposal. He countered that the French had pulled back their blockade to the southernmost end of the Adriatic Sea, and that none of the Anglo-French ships assigned to blockading the strait had been diverted to the Dardanelles.[72]

Haus also advocated strongly in favor of keeping his battleships, in particular all four ships of the Tegetthoff class, in reserve in the event of Italy's entry into the war on the side of the Entente. Haus believed that Italy would inevitably break her alliance with Austria-Hungary and Germany, and that by keeping battleships such as Tegetthoff safe, they could rapidly be employed against Italy. This strategy enabled Austria-Hungary to engage the Italians shortly after Italy's declaration of war in May 1915.[73]

Bombardment of Ancona

After failed negotiations with Germany and Austria-Hungary over Italy joining the war as a member of the Central Powers, the Italians negotiated with the Triple Entente for Italy's eventual entry into the war on their side in the Treaty of London, signed on 26 April 1915.[74] On 4 May Italy formally renounced her alliance to Germany and Austria-Hungary, giving the Austro-Hungarians advanced warning that Italy was preparing to go to war against them. Haus made preparations for Tegetthoff and her sister ships to sortie out into the Adriatic in a massive strike against the Italians the moment war was declared. On 23 May 1915, between two and four hours after the Italian declaration of war reached the main Austro-Hungarian naval base at Pola,[lower-alpha 3] the Austro-Hungarian fleet, including Tegetthoff, departed to bombard the Italian coast.[67][75]

While several ships bombarded secondary targets and others were deployed to the south to screen for Italian ships that could be steaming north from Taranto, the core of the Austro-Hungarian Navy, spearheaded by Tegetthoff and her sister ships, made their way to Ancona. The bombardment across the province of Ancona was a major success for the Austro-Hungarian Navy. In the port of Ancona, an Italian steamer was destroyed and three others damaged. The infrastructure of the port of Ancona and the surrounding towns was severely damaged. The railroad yard and port facilities in the city were damaged or destroyed, while local shore batteries defending them were knocked out. Multiple wharves, warehouses, oil tanks, radio stations, and coal and oil stores were set on fire by the bombardment, and the city's electricity, gas, and telephone lines were severed. Within the city itself, Ancona's police headquarters, army barracks, military hospital, sugar refinery, and Bank of Italy offices all saw damage. 30 Italian soldiers and 38 civilians were killed, while an additional 150 were wounded in the attack.[76][77]

The Austro-Hungarian Navy would later move on to bombard the coast of Montenegro, without opposition; by the time Italian ships arrived on the scene, the Austro-Hungarians were safely back in Pola.[78] The objective of the bombardment of Ancona was to delay the Italian Army from deploying its forces along the border with Austria-Hungary by destroying critical transportation systems.[75] The surprise attack on Ancona succeeded in delaying the Italian deployment to the Alps for two weeks. This delay gave Austria-Hungary valuable time to strengthen its Italian border and re-deploy some of its troops from the Eastern and Balkan fronts.[79] The bombardment also delivered a severe blow to Italian military and public morale.[80]

1916–1917

Largely unable to engage in major offensive combat operations after the Bombardment of Ancona due to the Otranto Barrage, Tegetthoff mostly relegated to defending Austria-Hungary's 1,130-nautical-mile (2,090 km; 1,300 mi) coastline and 2,172.4 nmi (4,023.3 km; 2,500.0 mi) of island seaboard for the next three years.[81] The lack of combat engagements, or even instances where Tegetthoff left port, is exemplified by the career of her sister ship, Szent István. The ship was unable to join her sisters in the Bombardment of Ancona and rarely left the safety of the port except for gunnery practice in the nearby Fažana Strait. She only spent 54 days at sea during her 937 days in service and made only a single two-day trip to Pag Island. In total, only 5.7% of her life was spent at sea; and for the rest of the time she swung at anchor in Pola Harbour.[82]

Despite Haus' death from pneumonia on 8 February 1917,[83] his strategy of keeping the Austro-Hungarian Navy, and particularly dreadnoughts like Tegetthoff, in port continued. By keeping Tegetthoff and her sister ships as a fleet in being, the Austro-Hungarian Navy would be able to continue to defend its lengthy coastline from naval bombardment or invasion by sea. The major ports of Trieste and Fiume would also remain protected. Furthermore, Italian ships stationed in Venice were effectively trapped by the positioning of the Austro-Hungarian fleet, preventing them from sailing south to join the bulk of the Entente forces at the Otranto Barrage.[84]

Maximilian Njegovan was promoted to admiral and appointed Commander-in-Chief of the Navy to replace Haus. With Njegovan appointed to higher office, command of the First Battle Division, which included that of Tegetthoff and her sister ships, fell to Vice-Admiral Anton Willenik. Njegovan had previously voiced frustration watching the dreadnoughts he had commanded under Haus sit idle at port, and upon taking command he had some 400,000 tons of coal at his disposal. However, he chose to continue the strategy of his predecessor, ensuring Tegetthoff would continue to see little to no combat.[85]

Having hardly ever ventured out to port except to conduct gunnery practice for the past two years, the most-significant moments Tegetthoff experienced while moored in Pola were inspections by dignitaries. The first such visit was conducted by Emperor Karl I on 15 December 1916. During this brief visit the Emperor inspected Pola's naval establishments and Szent István, but he did not board Tegetthoff.[86] Karl I returned to Pola in June 1917 in the first formal imperial review of the Austro-Hungarian Navy since 1902.[87] The third dignitary visit came during Kaiser Wilhelm II's inspection of Pola's German submarine base on 12 December 1917. Aside from these visits, the only action the port of Pola and Tegetthoff was subject to between the Bombardment of Ancona and the summer of 1918 were the more than eighty air raids conducted by the newly formed Italian Air Force.[88]

1918

Following the Cattaro Mutiny in February 1918, Admiral Njegovan was fired as Commander-in-Chief of the Navy.[5] Miklós Horthy de Nagybánya, commander of Tegetthoff's sister ship Prinz Eugen, was promoted to rear admiral and named Commander-in-Chief of the Fleet. Horthy used his appointment to take the Austro-Hungarian fleet out of port for maneuvers and gunnery practice on a regular basis. The size of these operations were the largest Tegetthoff had seen since the outbreak of the war.[89]

These gunnery and maneuver practices were conducted not only to restore order in the wake of several failed mutinies, but also to prepare the fleet for a major offensive operation. Horthy's strategic thinking differed from his two predecessors, and shortly after assuming command of the navy he resolved to undertake a major fleet action in order to address low morale and boredom, and make it easier for Austro-Hungarian and German U-Boats to break out of the Adriatic into the Mediterranean. After several months of practice, Horthy concluded the fleet was ready for a major offensive at the beginning of June 1918.[90]

Otranto Raid

Horthy was determined to use the fleet to attack the Otranto Barrage. Planning to repeat his successful raid on the blockade in May 1917,[91] Horthy envisioned a massive attack on the Allied forces with Tegetthoff and her three sister ships providing the largest component of the assault. They would be accompanied by the three ships of the Erzherzog Karl-class pre-dreadnoughts, the three Novara-class cruisers, the cruiser Admiral Spaun, four Tátra-class destroyers, and four torpedo boats. Submarines and aircraft would also be employed in the operation to hunt down enemy ships on the flanks of the fleet.[92][93][94]

On 8 June 1918 Horthy took his flagship, Viribus Unitis, and Prinz Eugen south with the lead elements of his fleet.[91] On the evening of 9 June, Szent István and Tegetthoff followed along with their own escort ships. Horthy's plan called for Novara and Helgoland to engage the Barrage with the support of the Tátra-class destroyers. Meanwhile, Admiral Spaun and Saida would be escorted by the fleet's four torpedo boats to Otranto to bombard Italian air and naval stations. The German and Austro-Hungarian submarines would be sent to Valona and Brindisi to ambush Italian, French, British, and American warships that sailed out to engage the Austro-Hungarian fleet, while seaplanes from Cattaro would provide air support and screen the ships' advance. The battleships, and in particular the dreadnoughts such as Tegetthoff, would use their firepower to destroy the Barrage and engage any Allied warships they ran across. Horthy hoped that the inclusion of these ships would prove to be critical in securing a decisive victory.[93]

En route to the harbour at Islana, north of Ragusa, to rendezvous with Viribus Unitis and Prinz Eugen for the coordinated attack on the Otranto Barrage, Szent István and Tegetthoff attempted to make maximum speed in order to catch up to the rest of the fleet. In doing so, Szent István's turbines started to overheat, and the speed of the two ships had to be reduced. When an attempt was made to raise more steam in order to increase their speed, Szent István produced an excess of smoke. At about 3:15 am on 10 June,[lower-alpha 4] two Italian MAS boats, MAS 15 and MAS 21, spotted the smoke from the Austrian ships while returning from an uneventful patrol off the Dalmatian coast. The MAS platoon was commanded by Capitano di corvetta Luigi Rizzo.[95] The individual boats were commanded by Capo timoniere Armando Gori and Guardiamarina di complemento Giuseppe Aonzo respectively. Both boats successfully penetrated the escort screen and split to engage each of the dreadnoughts. MAS 21 attacked Tegetthoff, but her torpedoes failed to hit the ship.[95] MAS 15 fired her two torpedoes successfully at 3:25 am at Szent István. Both boats evaded any pursuit although MAS 15 had to discourage the Austro-Hungarian torpedo boat Tb 76 T by dropping depth charges in her wake. Tegetthoff, thinking that the torpedoes were fired by submarines, pulled out of the formation and started to zigzag to throw off any further attacks. She repeatedly fired on suspected submarine periscopes.[96] Meanwhile, Szent István was hit by two 45-centimetre (18 in) torpedoes abreast her boiler rooms. Efforts to plug the holes in the ship failed.[96][93] Upon returning to the formation at 4:45 am, Tegetthoff attempted to take Szent István in tow, which failed.[97] After it became clear Szent István would sink, the crew of Tegetthoff emerged onto her decks to salute the sinking ship. At 6:12 am, with the pumps unequal to the task, Szent István capsized off Premuda.[96][93]

Film footage and photographs of Szent István's last half-hour were taken by Linienschiffsleutnant Meusburger of Tegetthoff with his own camera and by an official film crew. These films were later spliced together and exhibited in the United States after the war, where the proceeds were eventually used to feed children in Austria following the ending of the war.[95] Fearing further attacks by torpedo boats or destroyers from the Italian navy, and possible Allied dreadnoughts responding to the scene, Horthy believed the element of surprise had been lost and called off the attack. Tegetthoff and the rest of the fleet returned to the base at Pola where it would remain for the rest of the war.[98][99]

End of the war

On 17 July 1918, Pola was struck by the largest aid raid the city would see during the war. 66 Allied planes dropped over 200 bombs, though Tegetthoff was unharmed in the attack.[100]

By October 1918 it had become clear that Austria-Hungary was facing defeat in the war. With various attempts to quell nationalist sentiments failing, Emperor Karl I decided to sever Austria-Hungary's alliance with Germany and appeal to the Allied Powers in an attempt to preserve the empire from complete collapse. On 26 October Austria-Hungary informed Germany that their alliance was over. In Pola the Austro-Hungarian Navy was in the process of tearing itself apart along ethnic and nationalist lines. Horthy was informed on the morning of 28 October that an armistice was imminent, and used this news to maintain order and prevent a mutiny among the fleet. While a mutiny was spared, tensions remained high and morale was at an all-time low.[101]

On 29 October the National Council in Zagreb announced Croatia's dynastic ties to Hungary had come to a formal conclusion. This new provisional government, while throwing off Hungarian rule, had not yet declared independence from Austria-Hungary. Thus Emperor Karl I's government in Vienna asked the newly formed State of Slovenes, Croats and Serbs for help maintaining the fleet stationed at Pola and keeping order among the navy.[102] Emperor Karl I, attempting to save the Empire from collapse, agreed to transfer all of Austria-Hungary's ships to the National Council, provided that the other "nations" which made up Austria-Hungary would be able to claim their fair share of the value of the fleet at a later time.[103]

The Austro-Hungarian government thus decided to hand over the bulk of its fleet to the State of Slovenes, Croats and Serbs without a shot being fired. This was considered preferential to handing the fleet to the Allies, as the new state had declared its neutrality. Furthermore, the newly formed state had also not yet publicly dethroned Emperor Karl I, keeping the possibility of reforming the Empire into a triple monarchy alive. The transfer to the State of Slovenes, Croats and Serbs began on the morning of 31 October, with Horthy meeting representatives from the South Slav nationalities aboard his flagship, Viribus Unitis. After "short and cool" negotiations, the arrangements were settled and the handover was completed that afternoon. The Austro-Hungarian Naval Ensign was struck from Viribus Unitis, and was followed by the remaining ships in the harbor. The head of the newly-established navy for the State of Slovenes, Croats and Serbs, fell to Captain Janko Vuković, who was raised to the rank of admiral and took over Horthy's old responsibilities as Commander-in-Chief of the Fleet. He selected Tegetthoff's sister ship Viribus Unitis as his flagship.[104][105]

On 1 November 1918, Viribus Unitis was destroyed when two men of the Regia Marina, Raffaele Paolucci and Raffaele Rossetti, rode a primitive manned torpedo (nicknamed Mignatta or "leech") into the naval base at Pola and attacked her using limpet mines. When the mines exploded at 6:44 am, the battleship sank in 15 minutes; Vuković and 300–400 of the crew went down with her. Tegetthoff was unharmed in the attack.[106][2]

Post-war

The Armistice of Villa Giusti, signed between Italy and Austria-Hungary on 3 November 1918, refused to recognize the transfer of Austria-Hungary's warships to the State of Slovenes, Croats and Serbs. As a result, on 4 November 1918, Italian ships sailed into the ports of Trieste, Pola, and Fiume. On 5 November, Italian troops occupied the naval installations at Pola.[107] While the State of Slovenes, Croats and Serbs attempted to hold onto their ships, they lacked the men and officers to do so as most sailors who were not South Slavs had already gone home. The National Council did not order any men to resist the Italians, but they also condemned Italy's actions as illegitimate. On 9 November, all remaining ships in Pola harbor had the Italian flag raised. At a conference at Corfu, the Allied Powers agreed the transfer of Austria-Hungary's Navy to the State of Slovenes, Croats and Serbs could not be accepted, despite sympathy from the United Kingdom.[108]

Faced with the prospect of being given an ultimatum to surrender the former Austro-Hungarian warships, the National Council agreed to hand over the ships beginning on 10 November 1918.[109] In March 1919, Tegetthoff and Erzherzog Franz Ferdinand, both flying the Italian flag, were escorted into Venice where they were shown as a war trophies by the Italians. It would not be until 1920 when the final distribution of the ships was settled among the Allied powers under the terms of the Treaty of Saint-Germain-en-Laye, with Tegetthoff being formally ceded to Italy. During that time period, she starred in the movie Eroi di nostri mari ("Heroes of our seas") which depicted the sinking of Szent István. Following the adoption of the Washington Naval Treaty in 1922, she was broken up at La Spezia between 1924 and 1925.[34] After the Tegetthoff was dismantled, one of her anchors was placed on display at the Monument to Italian Sailors at Brindisi, where it can still be found.[110]

Following Nazi Germany's incorporation of Austria via the Anschluss of March 1938, Adolf Hitler used Austria-Hungary's naval history to appeal to the Austrian public and obtain their support. Hitler lived in Vienna during the development of much of the Austro-Hungarian Navy, and thus decided upon an "Austrian" sounding name for a German cruiser which was under construction at Kiel in 1938.[111] The cruiser was originally to be named Tegetthoff by the Kriegsmarine, after Wilhelm von Tegetthoff. However, concerns over the possible insult to Italy and Benito Mussolini of naming the cruiser after the Austrian victor of the Battle of Lissa, led Hitler to adopt Prinz Eugen as the ship's namesake, after the Austrian general Prince Eugene of Savoy.[112][113] Prinz Eugen was launched on 22 August 1938,[114] in a ceremony attended by Hitler and the Governor (German: Reichsstatthalter) of Ostmark, Arthur Seyss-Inquart, who made the christening speech. Also present at the launch was Regent of Hungary, Admiral Miklós Horthy. Horthy had previously commanded Tegetthoff's sister ship Prinz Eugen from 24 November 1917 to 1 March 1918 and had commanded the Austro-Hungarian Navy in the final months of World War I. Horthy wife's, Magdolna Purgly, performed the christening.[115] In reference to her originally planned name and in homage to the Austro-Hungarian Navy, the bell from Tegetthoff was presented to the German cruiser Prinz Eugen on 22 November 1942 by the Regia Marina.[116] After World War II, the bell from Tegetthoff was placed on display in Graz, Austria, where it can still be viewed.[117]
