During World War I, "Du Chayla" operated in the Atlantic Ocean on patrol for German commerce raiders from the start of the war in July 1914 to 1916. That year, she was transferred to the Red Sea, where she spent the next two years. In late 1918, she was reassigned to the Levant Squadron; by that time, many of her guns had been removed for use by the French Army ashore. Her armament consisted of two of the 164 mm guns, four guns, and four 47 mm guns. Immediately after the war in late 1918, she joined the French fleet that entered the Black Sea to intervene in the Russian Civil War, though she remained there only into the following year, when she was recalled to France. "Du Chayla" was struck from the naval register in 1921 but remained in the Navy's inventory until 1933, when she was broken up.
