After victory at Isandwhlana in January 1879, Zulu commander Ntshingwayo Khoza made an effort to acquire guns from the battlefield. During the course of an intensive training programme, he achieved the effect of having his own Zulu gun battalions, to accompany the Impis in battle. This created a formation similar to the Spanish Tercios of the 16th century, which in the British colonial theatre, was a devastating weapon.
A costly defeat at Rourke's Drift made Khoza re-evaluate the effectiveness of Zulu forces. Requesting an audience with King Cetshwayo, Khosa succeeded first in replacing his ineffective subordinate Prince Mpande, with his political ally Dabulomanzi, and then received permission to set up his gun college.
