Design and construction

Brumaire was ordered by the French Navy as part of its 1906 programme and was laid down at the Cherbourg Naval Yard in October of that year. Work progressed slowly, and she was not launched until 29 April 1911. She was commissioned on 20 March 1912. Brumaire 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. Brumaire was named for a month of the French Revolutionary calendar.

Service history

Brumaire was in service during the First World War and saw action throughout on patrol and close blockade duty. She remained on active duty at the end of hostilities, when many of her class were de-commissioned. Brumaire was stricken and disarmed in 1928, and scrapped in 1930.
