The Buffalo River (Zulu: uMzinyathi; Afrikaans: Buffelsrivier) is the largest tributary of the Tugela River in South Africa. With a total length of 426 km (265 mi), its source is in Majuba Hill, "Hill of Doves" in the Zulu language, located northeast of Volksrust, close to the Mpumalanga / KwaZulu-Natal border. It follows a southerly route into KwaZulu-Natal past Newcastle then turns southeast past Rorke's Drift, before joining the Tugela River[1] at Ngubevu near Nkandla. During the nineteenth century it formed part of the boundary between the Colony of Natal and Zululand.
The Buffalo River has a number of tributaries, including the Ingagane from the SW and the Blood River from the NE, which it joins near Kandi Mountain.[2] Rorke's Drift is a ford across the Buffalo River which is one of the famous places of the 1878-79 Anglo-Zulu War and Isandhlwana is another important place of that war located about 20 km SE of the river, not far from the confluence with the Tugela.[citation needed]
