Anglo-Zulu War his own initiative, without the approval of the British government and with the intent of instigating a war with the Zulu, had presented an ultimatum on 11 December 1878, to the Zulu king Cetshwayo with which the Zulu king could not comply, including disbanding his army and abandoning key cultural traditions. Bartle Frere then sent Lord Chelmsford to invade Zululand after this ultimatum was not met. The war is notable for several particularly bloody battles, including an opening victory of the Zulu at the Battle of Isandlwana, followed by the defeat of a large Zulu army at Rorke's Drift by
Paul Kruger British campaign—he advised the use of Boer tactics, making laagers at every stop and constantly scouting ahead—but refused Frere's request that he accompany one of the British columns, saying he would only help if assurances were made regarding the Transvaal. Chelmsford thought the campaign would be a "promenade" and did not take Kruger's advice. Soon after he entered Zululand in January 1879, starting the Anglo-Zulu War, his unlaagered central column was surprised by Cetshwayo's Zulus at Isandlwana and almost totally destroyed. The war in Zululand effectively ended on 4 July 1879 with Chelmsford's decisive victory at the Zulu capital Ulundi.
