Bernoulli was ordered by the French Navy as part of its 1906 programme and was laid down at the Arsenal de Toulon in November of that year. Work progressed slowly, and she was not launched until 1 June 1911. She was commissioned on 29 October 1912. She was equipped with licence-built M.A.N. diesel engines for surface propulsion, and electric motors for power while submerged. She carried eight torpedoes, two internally and six externally.[2]Bernoulli was named for Daniel Bernoulli, the 18th century Swiss mathematician,[3] and other members of the Bernoulli family.[a]
Service historyedit
On 30 November 1914, under the command of Lt. Defforges, Bernoulli attempted to penetrate the harbour at Cattaro. She was detected and forced to retire. On 28 April 1915 Bernoulli made another attempt on Cattaro. On this occasion she gained entrance, but found no targets and again had to retire. On 4 May 1916, now under the command of Lt. Rene Audry, Bernoulli sighted the Austrian destroyer SMS Csepel. She closed and attacked, scoring a torpedo hit on Csepel’s stern. Czepel was badly damaged, and thought to have sunk, but in fact gained port.[3] On 15 May 1917, during the aftermath of the battle at the Otranto Barrage, Bernoulli encountered a group of Austrian destroyers running for home, and fired on Balaton. However this attack was unsuccessful and Balaton escaped.[4] On 27 October 1917 Bernoulli sighted the German U-boat UC 38. She closed and attacked but was unable to score a hit; UC 38 escaped without damage. Bernoulli’s final patrol was in February 1918, on close blockade duty off Cattaro. She was not heard from after 13 February 1918 and is believed to have struck a mine off Cattaro and sunk. All 23 of her crew were lost.[2][5] Her commander, Rene Audry, was honoured by having a submarine named after him.[3]
Notesedit
^ abcThough the French Navy named this submarine for members of the Bernoulli family, it seems they did not use the same spelling; according to the sources here the boat's name is Bernouilli.
