''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-builtService history
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. 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.Halpern p165 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.Sieche Her commander, Rene Audry, was honoured by having a submarine named after him.Notes
