After the Armistice of Mudros was signed on 30 October between the Allies and the Ottoman Empire, the ship participated in the early stage of the occupation of Constantinople beginning on 12 November.
By 8 December Mirabeau was already deployed to the Black Sea to support White Russian forces in Sevastopol and deter Soviet forces who were advancing on the city during the Russian Civil War.
Mirabeau ran aground during a snowstorm on 18 February 1919 off the Crimean coast.
She could not be refloated until 6,000 metric tons (5,900 long tons) of weight were removed.
To this end, her guns, turret armour, most of her boilers, coal, ammunition and the upper strake of belt armor was disembarked.
After several weeks of effort, the ship was refloated on 6 April and she was towed by the Russian cruiser Kagul and the tugboat Thernomore to a drydock in Sevastopol to repair any damage and to have her equipment reinstalled.
This process began on 12 April, but Mirabeau was refloated three days later as news was received of the Red Army's advance on the city.
Only her guns, ammunition and part of her armor had been replaced by the time the city was evacuated by the Allies on 5 May. She was towed to Constantinople by the battleship Justice and five tugs where she remained from 7–15 May. Justice then resumed the tow and they reached Toulon on the 24th.
After an inspection of the ship in a drydock, Mirabeau was stricken on 22 August and turned over as compensation to the company that salvaged the pre-dreadnought battleship Liberté.
Her hulk was towed to Savona, Italy, to be scrapped on 28 April 1922.
