Relieved by the aviso "Coëtlogon", "Dupleix" was stationed in the northern port of Hakodate during the Battle of Hakodate, in order to guarantee French interests there. She brought back Captain Jules Brunet and his companions from Hakodate to Yokohama after the fall of the Republic of Ezo. From July 1870 to February 1871, "Dupleix" blockaded the German frigate in Nagasaki as part of operations during the Franco-Prussian War. In March, "Dupleix" sailed back to Cherbourg to be decommissioned. From 1876 to 1886, "Dupleix" was re-armed every year from March to October to monitor fishery operations in Iceland. She was struck in 1887.
