Alexander Mortier de Fontaine
French adventurer, soldier, and policeman (1838–1885)
Alexander Mortier de Fontaine, sometimes known as Alexander Fountain, was a French sailor who served as the Commander of the Native Auxiliary Force of the Straits Settlements Police Force, which gained a reputation for fearlessness and ferocity during the Klang War. After Klang was recaptured, he took a contingent of 85 of the Auxiliary with him to Sungei Ujong, known as De Fontaine's Arabs. Because he had served for several militaries by the time of his first major command, he was often called a mercenary, an adventurer, a drifter, and an aimless wanderer. After these major campaigns, he became an inspector in Singapore for nearly a decade, before becoming the 2nd-serving Commandant of the British North Borneo Constabulary, where in 1885 he was killed during the Kawang Amok.
