A series of nine wars was waged against the Xhosa between 1779 and 1879 along the Great Fish River which then formed the eastern border of Cape Colony.
The Xhosa allowed themselves to be convinced by the prophet Mlanjeni that they were bulletproof and by Nongqawuse that slaughtering their cattle would drive the white man out off their land.
Funnily enough, neither was right and it fell to Lord Chelmsford summarily to finish off the campaign in 1879 before he headed up to the Colony of Natal, only to be taught a bit of lesson himself at the Battle of Isandlwana.
