 French Indochina was formed in October 1887 from Annam (Trung Kỳ, central Vietnam), Tonkin (Bắc Kỳ, northern Vietnam), Cochinchina (Nam Kỳ, southern Vietnam, and Cambodia, with Laos added in 1893).Within French Indochina, Cochinchina had the status of a colony, Annam was nominally a protectorate where the Nguyễn dynasty still ruled, and Tonkin had a French governor with local governments run by Vietnamese officials.After Gia Định fell to French troops, many resistance movements broke out in occupied areas, some led by former court officers, such as Trương Định, some by peasants, such as Nguyễn Trung Trực, who sank the French gunship L'Esperance using guerilla tactics.
