The Sixth Frontier War (1834–1836) between the Xhosa and the British is sometimes known as the Hintsa War. The war broke out when a Cape government commando party patrolled land near the Kat River which was occupied by Rharhabe chiefs Maqoma, Tyali and Botumane in December 1834. These patrols increased the bitterness that Maqoma and Tyali had after they had been forcibly removed by the Cape government from the Tyume Valley in 1833. On 21 December 1834, large force of some 10 000 RharhabeXhosas led by Maqoma, and Tyali swept into the Cape Colony, devastated the country between the Winterberg and the sea. Hintsa offered moral support to the chiefs but never sent an army to assist them.
