Diderot, Mirabeau and Vergniaud briefly participated in the occupation of Constantinople after the end of the war and the latter two ships were sent to the Black Sea in early 1919 during the Southern Russia Intervention.
Vergniaud's crew mutinied after one of its members was killed when a protest against intervention in support of the Whites was bloodily suppressed and forced the return of the French ships supporting the Whites.
Mirabeau ran aground in February 1919 off the coast of the Crimea and could not be refloated until some of her guns and armor were removed.

All of the surviving ships except Condorcet were reduced to second-line roles by 1920.
Mirabeau was not repaired after her salvage and was hulked for a few years before being sold.
Vergniaud was in bad shape and became a target ship before she was sold for scrap.
Voltaire and Diderot had their underwater protection modernized in the early 1920s and became training ships before they were condemned in the mid-1930s.
Condorcet was assigned to the Channel Division in the early 1920s before she too had her underwater protection modernized.
She also became a training ship after its completion, but she was hulked in 1931 and became a depot ship for the torpedo school.
The ship was captured intact when the Germans occupied Toulon in November 1942 and was used by them as a barracks ship.
Condorcet was scuttled by the Germans in August 1944 and refloated the following year before being scrapped.

Danton's wreck was discovered in 2007 between Algeria and Sardinia at a depth of over 1,000 meters (3,300 ft).
