According to the diary of Henry Francis Fynn, Dingiswayo's death (c.1818) was the result of Shaka's treachery, though firm testimony of this is lacking. However, it is known that when Dingiswayo fought his last battle, Shaka did not arrive at the scene until after his overlord's capture. He thus retained his forces intact. Zwide later murdered Dingiswayo, and, when the leaderless Mthethwa state collapsed, Shaka immediately assumed leadership and began conquering surrounding chiefdoms himself, adding their forces to his own and building up a new kingdom.
The defeat of the Ndwandwe
Zwide decided to smash his new rival. After a first expedition had been defeated by the superior control and strategies of the Zulu at Gqokoli Hill, Zwide, in April 1818, sent all his army into Zululand. This time Shaka wore out the invaders by pretending he was retreating and drawing Zwide's forces deep into his own territory; then, when he had successfully exhausted the invaders, he flung his own regiments on them and defeated them conclusively at the Mhlathuze river. This defeat shattered the Ndwandwe state. Part of the main Ndwandwe force under Shoshangane, together with the Jere under Zwangendaba, the Maseko under Ngwane, and the Msene led by Nxaba, fled northwards. The survivors of the main Ndwandwe force settled for a time on the upper Pongola River. In 1826, under Zwide's successor, Sikhunyane, they again fought the Zulu, but were totally routed. The majority then submitted to Shaka. He was able to recruit additional warriors from these sources and proceeded to train them in his own methods of close combat.
Shaka's supremacy
By then, Shaka had no major rival in the area of present day KwaZulu/Natal. During his brief reign, which lasted only ten years after his final defeat of the Ndwandwe, his regiments continuously went on campaign, steadily extending their assaults further afield as the areas near at hand were stripped of their cattle.
