The Boers first struck at the Battle of Kraaipan on 12 October 1899. Late at night, 800 commandos rode south into the Cape Colony, attacking the British garrison at Kraaipan and cutting railway and telegraph lines. Although the British repelled their advance at the Battle of Talana Hill, and the Battle of Elandslaagte, the Boers continued to pour south, besieging the British settlement of Ladysmith and advancing on Mafeking and Kimberley.
