French submarine Bernoulli

[2] 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.

[a] On 30 November 1914, under the command of Lt. Defforges, Bernoulli attempted to penetrate the harbour at Cattaro.

On 4 May 1916, now under the command of Lt. Rene Audry, Bernoulli sighted the Austrian destroyer SMS Csepel.

[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.

Bernoulli’s final patrol was in February 1918, on close blockade duty off Cattaro.
