"Mavumengwana kaNdlela, a chief of the Ntuli people. He was a senior induna of the uThulwana ibutho, and a close confident of King Cesthwayo kaMpande.
His father, Ndlela kaSompisi. had been a senior induna of King Dingane. Who paid with his life for having brought the ignomy of defeat on Dingane's forces.
When King Mpande came to power he treated Mavumengwana almost as one of his own, and helped in raising him.
Mavumengwana and King Mpande's son Cetshwayo kaMpande, were of a like age and served the same ibutho.
When King Cetshwayo despatched his men to confront the advance of No.3 Column, it was Ntshingwayo kaMahole and Mavumengwana who commanded the forces that defeated British and Colonial forces at Isandlwana.
I cannot find anything which verifies any claim that he present at Rorke's Drift with Prince Dabulamanzi.
However, it was Mavumengwana and his brother, Godide, together with Prince Dabulamanzi, who commanded the Zulu forces which were responsible for the investment of the British force at Eshowe."
