Second Boer War
First phase of the War
The war had three phases. In the first phase, the Boers mounted preemptive strikes into British-held territory in Natal and the Cape Colony, besieging the British garrisons of Ladysmith, Mafeking, and Kimberley. The Boers then won a series of tactical victories at Colenso, Magersfontein, and Spion Kop.
