used as anti-aircraft (AA) guns. They were later supplemented by a pair of Mle 1891 G guns on anti-aircraft mounts. On 27 April 1916, the French began using the port of Argostoli on the Greek island of Cephalonia as a base. Around this time many men from the battleships' crews were transferred to anti-submarine ships. At the beginning of 1917, the French began to use the Greek island of Corfu as well, but growing shortages of coal severely limited the battleships' ability to go to sea. The situation was so bad that Vice-Admiral Gabriel Darrieus wrote in 1917: The military capabilities of the , which has already been badly affected by the shortages of personnel and constant changes in the general staff, need to be maintained by frequent exercises, and although from March to June we were able to follow a normal pattern, the coal crisis is currently preventing any manoeuvres or gunnery training, even for the ships returning from repairs. The big ships have lost 50 per cent of the capability they had several months ago. In 1918, they were almost immobile, leaving Corfu only for maintenance and repairs. On 1 July, the Naval Army was reorganised with Jean Bart, Paris and Courbet assigned to the 2nd Battle Division of the 1st Battle Squadron. Interwar years After the Armistice of Mudros was signed on 30 October between the Allies and the Ottoman Empire, the ship participated in the occupation of Constantinople.

A few days after bombarding Bolshevik troops advancing on Sevastopol on 16 April and forcing them to retreat, her war-weary crew briefly mutinied on 19 April, inspired by socialist and revolutionary sympathisers. Jean Barts captain was able to restore order aboard his ship the following day and mustered a landing party to patrol the city. Frances crew was still mutinous, so Vice-Admiral Jean-Françoise-Charles Amet, commander of the ships in the Black Sea, hoped to reduce tensions by meeting the mutineers' demands for leave by letting crewmen with a history of good behaviour ashore. The sailors mingled with a pro-Bolshevik demonstration and the mixed group was challenged by a company of Greek infantry which opened fire. The demonstrators fled and encountered Jean Barts landing party, which also fired upon them. A total of about 15 people were wounded, included six
