SS Tubantia was a Dutch-owned ocean liner that was launched in Scotland in 1914. She and her sister ship Gelria were the largest and swiftest ships in the Koninklijke Hollandsche Lloyd (KHL) fleet. They were also the first KHL ships to have quadruple-expansion steam engines.
A U-boat sank Tubantia in the North Sea in 1916. She was the largest neutral ship sunk in the First World War. Germany variously tried to claim that a British mine or a British torpedo had sunk her, or even a German torpedo that had been astray by itself for ten days. The Dutch public was outraged at both the sinking and the German disinformation campaign. KHL's compensation claim against Germany was not settled until 1922.
Tubantia was reputed to be carrying £2 million in specie when she was sunk. Between 1924 and 1927 a British salvage diving operator tried to recover the gold, without success. However, the decision by an English court on a legal dispute between two rival salvors wishing to attempt the salvage remains a leading part of the case law of marine salvage.
In 1913 and 1914 Alexander Stephen and Sons built a pair of sister ships at its yard in Linthouse, Glasgow, for KHL. Gelria was launched in May 1913 and completed that October.[1] Tubantia was built as yard number 455, launched on 15 November 1913, and completed on 11 March 1914.[2] She cost £300,000.
Tubantias length overall was [3] and her registered length was . Her beam was and her depth was . Her tonnages were, and . She had berths for 1,477 passengers: 252 first class, 236 second class, 135 third class and 854 steerage. Her holds had capacity for of baled cargo.[2]
Tubantia had twin screws, each driven by a quadruple-expansion steam engine. Together her twin engines were rated at 1,725 NHP or 11,000 ihp.[2] She achieved NaNkn on her sea trials, exceeding the speed required by the contract to build her,[3] and could cruise at 16kn.[2]
One author claims Tubantia was among the most luxurious passenger ships of her era. Her electrical equipment ranged from laundry equipment and ventilation fans to cigar lighters. Her name was spelt out in electric lights, suspended between her two funnels.
KHL registered Tubantia at Amsterdam. Her code letters were PVDL. Her navigation equipment included submarine signalling, and she was equipped for wireless telegraphy. Her call sign was PET.
Tubantia worked KHL's route between Amsterdam and Buenos Aires. When the First World War broke out in August 1914, she was returning from South America with £500,000 in gold destined for banks in London, much of which for the German Bank of London.[4] She was also carrying about 150 German reservists in steerage and a cargo of grain destined for Germany.[4] [5] After she called at Vigo, Spain, the Royal Navy cruiser stopped Tubantia, put a boarding party aboard her,[5] and escorted into Plymouth.[4] There, Royal Marines disembarked the German reservists,[5] and the gold was confiscated and taken ashore.[6] Tubantia was released then from Plymouth and allowed to resume her voyage.
The New York Times reported that on 17 October Tubantia ran aground on the coast of Kent while en route from Buenos Aires to Rotterdam. Aid had been summoned from Dover, but the report did not say whether Tubantia was damaged.[7]
In December 1915 the Overseas News Agency in Berlin claimed that the British authorities had seized all the mail and parcels from South America aboard Tubantia.[8] The US expressed concern that the British had seized items from two Dutch ships in transatlantic service between the Netherlands and the US – and . The British Foreign Office replied by stating that contraband intended for Germany — which included four packages of rubber, and seven containers of wool — had been found among Tubantias mail.[9]
On 15 March 1916 Tubantia left Amsterdam on a scheduled sailing to Buenos Aires. She carried only 80 passengers. At 0200 hrs on 16 March she anchored about 4nmi from the North Hinder Lightship, and about 50nmi off the Dutch coast, to await dawn and avoid misidentification or attack. She was completely illuminated.
At about 0230 hrs her lookouts sighted a stream of bubbles rapidly approaching her starboard side. There was an explosion, and she quickly began to sink. Three ships answered her distress signals: Breda, Krakatau, and La Campine. Between them the rescued all 80 passengers and all 294 crew members from Tubantia. She was the largest neutral vessel sunk during the war.
A propaganda war between British and German newspapers broke out, with Germany trying to blame Britain, and Britain rebutting the accusation. Both sides had in mind the serious violation of Dutch neutrality. German newspapers first claimed that a British mine must have sunk Tubantia. The British reported that a German torpedo had sunk her. German newspapers replied that if a torpedo had sunk the ship, it had to have been British. A drifting lifeboat from Tubantia was found, examined, and found to have bronze torpedo fragments embedded in it. Germany was the only country that used bronze in its torpedoes.
Presented with evidence that it was torpedo no. 2033 which had been assigned to the small, coastal submarine,[10] German authorities presented a forged log from UB-13 that showed her nowhere near Tubantia at the time of the attack. They claimed UB-13 had fired that specific torpedo at a British warship on 6 March, ten days before Tubantia was sunk. The US Minister to the Netherlands, Henry van Dyke, writing in Fighting for Peace in 1917, called this explanation "amazing" and derided it:
The Dutch public was furious at what it believed a hostile German act. To help divert the public anger against his country, German diplomat Richard von Kühlmann began a coordinated campaign to spread rumors of an impending British invasion of the Netherlands. One author calls the German plan a "propaganda coup". The rumors caused some panic in the streets, and the Dutch government declared a four-day emergency from 30 March to 2 April.
Despite denials and rumor-spreading, Germany nevertheless offered compensation in the amount of £300,000, Tubantias original cost. Rejected by the Dutch, the two countries agreed to have the issue arbitrated after the end of the war. The dispute was finally settled in 1922, when KHL was awarded compensation equivalent to £830,000.
In 1924 two sets of salvors contested the salvage rights to the wreck, each wishing to try to recover £2 million of gold coins that she was reputed to be carrying. An English court resolved the dispute, and its decision The Tubantia [1924] P 78, remains the leading authority under English law as to when a salvor takes possession of a sunken shipwreck. The winning party, Royal Naval Air Service veteran Sydney Vincent Sippe, spent three years and £100,000 trying to access the gold, but abandoned the attempt after concluding that it was too dangerous for divers to recover it.
