The Boer generals were not unduly concerned by the news that the British had taken the kop. They knew that their artillery on Tabanyama could be brought to bear on the British position and that rifle fire could be brought to bear from parts of the kop not yet occupied by the British. However, the Boer generals also knew that sniping and artillery alone would not be sufficient to dislodge the British – and the Boer position was desperately vulnerable. If the British immediately established positions on Conical Hill and Aloe Knoll (the two unoccupied kopjes on the kop itself) they could bring their artillery to bear on Tabanyama, threatening the key Boer positions there. More importantly, there was a risk that the British would storm Trinity Peaks "(Drielingkoppe)" to the eastern end of Spion Kop. If Twin Peaks fell, the British would be able to turn the Boers' left flank and annihilate the main Boer encampment. The Boer generals realised that Spion Kop would have to be stormed quickly if certain defeat were to be averted.
