Naval service

Delfin was based at Tenedos island in the Balkan War from where she carried out the first modern submarine torpedo attack (unsuccessful) on 9 December 1912. Lt-Cdr Paparrigopoulos sighted the Turkish cruiser Medjidieh leaving the Dardanelles with 5 escorts. An hour later he fired a torpedo from 500 meters but it did not run properly and sank. Both served under the French flag 1917-18, they were discarded in 1920 and placed on the sale list in 1921.
