In January 1879, the official Sir Henry Bartle Frere, a personal friend of Chelmsford, engineered the outbreak of the Anglo-Zulu War by issuing the Zulu king Cetshwayo an ultimatum to effectively disband his military. Cetshwayo refused this ultimatum, an act which led to an outbreak of war between the British Empire and the Zulu Kingdom. A British expeditionary force under the command of Chelmsford invaded the Zulu Kingdom, heading in three columns towards the Zulu capital, Ulundi. The force was attacked by a Zulu force at Isandlwana, during which the Zulus overran and destroyed the central column of Chelmsford's separated forces. The engagement was an unexpected victory for the Zulus, which threw British war plans into disarray.
