- The Dutch liner SS Tubantia is torpedoed without warning in the North Sea. En route from Amsterdam to Buenos Aires, the liner is anchored 90km off the Dutch coast for the night, awaiting daylight. At 2.30am she is struck by a torpedo from the German submarine UB-13 and begins to sink. All 80 passengers and all 294 members of the crew are rescued, but the liner sinks – the largest neutral vessel to be sunk during WWI. Tubantia sank with a reputed £2 million worth of gold coins, and in 1924 was the subject of a salvage dispute. British war hero Sydney Vincent Sippe spent three years and £100,000 trying to access the gold, but abandoned the attempt concluding that it was too dangerous. The Sinking of the SS Tubantia
