He fought with Tourville around Sicily and was wounded in the Battle of Agosta where De Ruyter was mortally wounded . In 1680 , Coëtlogon studied theology and considered entering the church . Although he returned to the sea , he was profoundly changed by this spiritual experience , and led an austere , celibate life . In 1683 , he commanded various ships , first around Denmark , then in North Africa . In 1688 he took part in the bombardment of Algiers under Jean II d ' Estrées . During the Nine Years ' War , he was part of Château - Renault ' s fleet which landed French troops in Ireland , and fought in the Battle of Bantry Bay on May 11 , 1689 ; on November 1 he was promoted to squadron leader .

He then became Naval Commander in Brest and received many decorations . The last four years of his life he lived in a Jesuit order . On June 1 , 1730 , he was finally made Marshal of France , six days before his death . Several ships were named after Coëtlogon , especially a frigate which was active during the Boshin war ( 1868 – 1869 ) in Japan , and later an armoured cruiser .
