A question about the Battle of Khambula (Zulu War)

Dec 2016
This one is a more specific question. I need your help, I am reading about battle of Khambula in the context of anglo-zulu war (29th march, 1879).

In the following link: The Battle of Khambula - The Zulu War you will find the British Regiments that took part in this battle but there is no mention about zulu regiments. I have read the books Isandlwana and Rorke's Drift by Ian Knight in Osprey Publishing. I ignore if these are good references for this war specifically but at least are easy to understand for those who are not historian, only occasional readers like me. In that books I was able to find the order of battle of Isandlwana and Rorke's Drift specifying the british forces and also the zulu forces. I want to know which zulu regiments took part in Khambula, I guess some of them also took part in Isandlwana and Rorke's Drift. Do someone has this information?

Thank you in advance.
