'''SM ''U-14''''' or '''''U-XIV''''' was a [[U-boat]] or [[submarine]] of the [[Austro-Hungarian Navy]] during the [[First World War]]. She was [[launch (ship)|launched]] in 1912 as the French {{sclass|Brumaire|submarine|1}} ''Curie'' (Q 87), but captured and rebuilt for service in the Austro-Hungarian Navy. At war's end, the submarine was returned to France and restored to her former name.

''Curie'' was launched in July 1912 at [[Toulon]] and completed in 1914. She measured just under {{convert|171|ft|m}} long and [[displacement (ship)|displaced]] nearly {{convert|400|MT|LT}} on the surface and just over {{convert|550|MT|LT}} when submerged. At the outbreak of the First World War in August 1914, ''Curie'' was assigned to duty in the [[Mediterranean]]. In mid-December, ''Curie''{{'}}s commander conceived a plan to infiltrate the Austro-Hungarian Navy's main base at [[Pula|Pola]], but during the 20 December attempt, the vessel became ensnared in harbor defenses. Two Austro-Hungarian ships sank ''Curie'', killing three of her crew; the remainder were taken prisoner.

The Austro-Hungarian Navy, which had a small and largely obsolete{{fact|date=October 2023}} U-boat fleet, immediately began salvage efforts and succeeded in raising the lightly damaged submarine in early February 1915. After a refit, the boat was [[commission (ship)|commissioned]] as SM ''U-14'' in June, but had little success early in her career. When her commander fell ill in October, he was replaced by [[Georg Ritter von Trapp]]. ''U-14'' was damaged by a [[depth charge]] attack in February 1916, and underwent an extensive modernization through November. Resuming duty under von Trapp, ''U-14'' sank her first ship in April 1917, but had her most successful patrol in August, when she sank five ships—including {{SS|Milazzo||2}}, reportedly the largest [[cargo ship]] in the world—in a six-day span.

In January 1918, von Trapp was replaced as commander, but neither of his two successors was able to match his accomplishments. In all, ''U-14'' sank 11 ships with a combined [[gross register tonnage]] of nearly 48,000 tons. Returned to France at the end of the war, she rejoined the French Navy in July 1919 under her former name of ''Curie''. She remained in service until 1928 and was scrapped in 1929.

== Design and construction ==
''Curie'' was a part of the 16-boat {{sclass|Brumaire|submarine|4}} authorized under the 1906 program. The ''Brumaire''-class boats were [[diesel engine|diesel]]-powered versions of the [[steam engine|steam]]-powered {{sclass|Pluviôse|submarine|0}} submarines (which had been authorized the year before), and, like the ''Pluviôse'' boats, were named after either months of the [[French Republican Calendar]] or scientists. ''Curie'' was named after [[Pierre Curie|Pierre]] and [[Marie Curie]].<ref name=Con-209 />

The ''Bruimaire'' class was designed by French naval designer [[Maxime Laubeuf]] and featured a [[hull (submarine)|double hull]]. The boats were {{convert|170|ft|11|in|m}} long, {{convert|17|ft|9|in|m}} [[beam (ship)|abeam]], with a [[draft (hull)|draft]] of {{convert|10|ft|2|in|m}} when surfaced. They had a [[displacement (ship)|displacement]] of {{convert|397|MT|LT}} surfaced and {{convert|551|MT|LT}} submerged. ''Curie'', like the other 15 submarines of the class, featured one {{convert|17.7|in|mm|adj=on}} bow [[torpedo tube]] and could carry as many as eight [[torpedo]]es. As built, ''Curie'' did not have a [[deck gun]].<ref name=Con-209 />

The ''Brumaire'' class featured twin [[propeller shaft]]s driven by two French license-built [[MAN SE|MAN]] 6-cylinder diesel engines on the surface, or by two [[electric motor]]s when submerged. ''Curie''{{'}}s diesel engines generated a total of {{convert|840|bhp|lk=in}} and could move the submarine at up to {{convert|13|kn|lk=in}} on the surface; her electric motors generated {{convert|660|shp|lk=in}} and could propel the boat up to {{convert|8.8|kn}} submerged. While traveling on the surface at {{convert|10|kn}}, ''Curie'' had a range of {{convert|1700|nmi|lk=in}}; the submarine's range while submerged was {{convert|84|nmi}} at {{convert|5|kn}}.<ref name=Con-209 />

''Curie'' was [[keel laying|laid down]] at the [[Arsenal de Toulon]] and [[launch (ship)|launched]] on 18 July 1912, completed by 1914, and [[commission (ship)|commissioned]] into the [[French Navy]].<ref name=Con-209 />

== French career and sinking ==
[[File:Manoeuvres navales 1914 - le sous-marin Curie.jpg|thumb|left|''Curie'' at sea near [[Toulon]], May 1914.]]
Like all the ''Brumaire''-class submarines, ''Curie'' began her First World War service in the [[Mediterranean]],<ref name=Con-209 /> and was one of the first French submarines to appear in the [[Adriatic]].<ref name=BS />

On 17 December 1914, ''Curie'', at the insistence of her French-Irish commander Gabriel O'Byrne, departed her base in the [[Ionian Sea]] under tow by the French [[armored cruiser]] {{ship|French cruiser|Jules Michelet||2}}.<ref name=Comp-224>{{harvnb|Compton-Hall|2004|p=224}}</ref> Depositing her charge {{convert|150|nmi}} from [[Pula|Pola]],<ref name=Comp-224 /> the site of the [[Austro-Hungarian Navy]]'s main base,<ref name=BS /> ''Jules Michelet'' departed, leaving ''Curie'' to proceed to the Austro-Hungarian base. ''Curie'' arrived the next day and began reconnoitering the entrance to the harbor. O'Byrne observed the entrance and exit paths of Austro-Hungarian vessels and plotted a course through the deployed defensive [[mine (naval)|mine]]s. On 19 December, O'Byrne took ''Curie'' in to observe the [[anti-submarine net]] that ran across the opening in a long, defensive [[breakwater (structure)|breakwater]] built to keep submarines from infiltrating the naval base.<ref name=Comp-224 /><ref>{{harvnb|von Trapp|2007|p=66}}</ref><!-- description of breakwater -->

Believing that he had accounted for all of the defensive measures, O'Byrne took ''Curie'' to a depth of {{convert|65|ft|m}} early on 20 December and, attempting an incursion into the harbor, heard the sounds of chains and wires dragging on the submarine's hull. When the sounds stopped after half a minute, O'Byrne brought ''Curie'' up to periscope depth to discover that he had only penetrated the outer net.<ref name=Comp-224 /> ''Curie''{{'}}s forward momentum carried her into the second net where she became "inextricably entangled".<ref name=Gib-69>{{harvnb|Gibson|Prendergast|2003|p=69}}</ref> When the submarine, still trapped in the net, was forced to surface for fresh air, ''Curie'' came under fire from the Austro-Hungarian destroyer {{SMS|Magnet||2}} and [[torpedo boat]] ''Tb 63 T'' which quickly sank her. Three of the twenty-six men on board were killed in the attack; the survivors — who included ''Curie''{{'}}s commander, O'Byrne — were all taken prisoner.<ref name=Sieche>{{cite web | last = Sieche | first = Erwin | title = French naval operations, engagements and ship losses in the Adriatic in World War One | url = http://www.gwpda.org/naval/fadri.htm | date = 30 December 2000 | publisher = Great War Primary Documents Archive, Inc. | access-date = 9 January 2008

== Salvage and Austro-Hungarian career ==
At the beginning of the First World War, the [[Austro-Hungarian Navy]]'s U-boat fleet consisted of six largely experimental submarines of three classes.<ref name=Con-341>{{harvnb|Gardiner|1985|p=341}}</ref>{{Ref label|2|Note 2}} The Navy had five larger, more modern submarines (what would have been the {{sclass|U-7|submarine|4||Austria-Hungary}}) under construction in Germany at the outbreak of war, but when the Navy became convinced that delivery of the ''U-7'' boats would be impossible, they were sold to Germany in November 1914.<ref name=Con-177>{{harvnb|Gardiner|1985|p=177}}</ref>{{Ref label|3|Note 3}}

Amidst Austro-Hungarian efforts to replace the now-unavailable ''U-7'' boats,<ref name=BS />{{Ref label|4|Note 4}} the largely intact ''Curie'', resting at a depth of {{convert|39|m|ft}}, became the focus of salvage efforts. Beginning on 21 December, the day after ''Curie''{{'}}s sinking, salvage crews raised the submarine in stages, finally bringing her to the surface on 2 February 1915.<ref name=BS />

The former ''Curie'', now assigned the designation ''U-14'', was reconditioned and [[commission (ship)|commissioned]] into the Austro-Hungarian Navy under the command of ''[[Korvettenkapitän]]'' Otto Zeidler on 1 June.<!-- all except commander --><ref name=BS /><ref name=KUK-U-14 /><!-- commander's name --> Zeidler remained in command until he fell ill,<ref>{{harvnb|von Trapp|2007|p=67}}</ref> and was replaced in mid-October by ''[[Linienschiffsleutnant]]'' [[Georg Ritter von Trapp]].<ref name=KUK-U-14 />{{Ref label|5|Note 5}} Under Zeidler's command and the first months of von Trapp's command, ''U-14'' had no successes.<ref name=KUK-U-14 />

In early February 1916, ''U-14'' joined {{SMU|U-4|Austria-Hungary|2}} for a patrol near [[Durrës|Durazzo]].<ref>{{harvnb|von Trapp|2007|p=68}}</ref> ''U-4'' came closest to scoring a success when she narrowly missed hitting {{HMS|Lowestoft|1913|6}}, a British {{sclass|Birmingham|cruiser}} on 7 February.<ref name=Sieche-20>{{harvnb|Sieche|1980|p=20}}</ref> ''U-14'' survived a depth charge attack, but made it back to port with all of her externally mounted torpedoes crushed and both fuel tanks leaking.<ref>{{harvnb|von Trapp|2007|p=76}}</ref>

When she put in for repairs, ''U-14'' was extensively modernized in a refit that kept her in port from February to November. The submarine was given a German-style [[conning tower]] that replaced the French-designed wet lookout platform. She was equipped with more powerful diesel engines, which increased her power output from {{convert|480|to|840|bhp}}. ''U-14''{{'}}s fighting potential was further enhanced by the installation of larger fuel tanks, which nearly quadrupled her range to {{convert|6500|nmi|km}}, up from her former maximum of {{convert|1700|nmi|km}}.<ref name=Con-343 />

On 28 April 1917, ''U-14'' was patrolling off the coast of Greece when she scored her first success, ''Teakwood'', a 5,315-ton British [[tanker (ship)|tanker]] headed from [[Port Arthur, Texas]], to [[Port Said]].<ref name=teak>{{cite Uboat.net

In another patrol in July, ''U-14'' sailed on the north side of the island of [[Corfu]] while headed for [[Santi Quaranta]], [[Albania]]. Because the harbor at Corfu was occupied by the French fleet at the time, ''U-14'' conducted a ''[[ruse de guerre]]'' by flying the submarine's former national flag, the [[French tricolor]], in order to pass unmolested.<ref>{{harvnb|von Trapp|2007|p=77}}</ref> Even though ''U-14''{{'}}s new conning tower made her look unlike any other ''Brumaire''-class boat,<ref name=Con-343 /> one French patrol plane was successfully fooled by the ruse. When ''U-14''{{'}}s crew first spotted the aircraft, flying towards them from the direction of the sun, there was not enough time to submerge. As the aircraft drew near, its French markings—and its cargo of bombs—became apparent to the crew. With no other course of action possible, ''U-14''{{'}}s crew waved their hats and handkerchiefs at the plane. As the French pilot passed overhead, he returned the waves, apparently unaware of the U-boat's true nationality.<ref>{{harvnb|von Trapp|2007|p=81}}</ref> The only success by ''U-14'' on this cruise was the sinking of ''Marionga Goulandris'', a Greek steamer, near [[Cape Matapan]].<ref name=mari>{{cite Uboat.net

''U-14''{{'}}s next war patrol was very successful, sinking five ships with a combined tonnage of 24,814, over half of her total tonnage sunk.<ref name=U14-ships /> ''U-14'' departed from the submarine base at [[Cattaro]] on 20 August and headed through the [[Straits of Otranto]], successfully evading the [[Otranto Barrage]], and [[Allies of World War I|Allied]] blockade of the passageway between Italy and [[Albania]].<ref name=Trapp-80>{{harvnb|von Trapp|2007|p=80}}</ref> Heading into the [[Ionian Sea]],<ref name=Trapp-80 /> von Trapp and ''U-14'' sank the French steamer ''Constance'' on 23 August {{convert|142|nmi}} northeast of [[Malta]].<ref name=cons>{{cite Uboat.net

In January 1918, Friedrich Schlosser replaced von Trapp as commander of ''U-14''.

After Austria-Hungary's surrender and the end of the First World War, ''U-14'' was returned to France and on 17 July 1919 rejoined the French Navy under her former name of ''Curie''. She was stricken in 1928 and scrapped in 1929.<ref name=Con-343 />
