One of the first proponents of the was the artillery general
Henri-Joseph Paixhans, who invented explosive
shell guns for warships during the 1820s. He advocated the use of these powerful guns on numerous small steam
warships that could destroy much larger battleships. Later, the
French Navy developed the concept more elaborately as it experimented with
torpedoes and
torpedo boats. The French Navy became one of the strongest proponents of this combat system by the end of the 19th century, particularly during the ministry of Admiral
Théophile Aube. The naval successes of the French Navy against
China during the
Sino-French War of 1883–1885 also tended to validate the potential of torpedo boats against conventional navies. France was also very active in the development of a
submarine fleet, again trying to rely on technical development to compensate for British numerical superiority of battleships. By the beginning of the 20th century, France was "undoubtedly the first navy to have an effective submarine force". Counter measures against the system consisted largely of
destroyers, designed to deter and destroy small torpedo units (in French, "destroyer" is , and in English, "destroyer" is a contraction of "torpedo boat destroyer"), the first of which was the . ==Commerce raiders==
