The Siege of Tourane (September 1858–March 1860) was a Vietnamese victory during the Cochinchina Campaign, a punitive campaign against the Vietnamese launched by France and Spain in 1858. A joint Franco-Spanish expedition under the command of Admiral Charles Rigault de Genouilly captured Tourane (modern Da Nang) in September 1858, but was then besieged in the city by the Vietnamese and forced eventually to evacuate it in March 1860.
