larger part of his force under Major-General Edward Woodgate to secure Spioen Kop. Lieutenant Colonel Alexander Thorneycroft was selected to lead the initial assault. (Thorneycroft was one of six "special service" officers, among who were also Robert Baden-Powell and Herbert Plumer, despatched to South Africa shortly before the war to recruit local irregular corps. Thorneycroft's mounted infantry were raised in Natal and numbered 360.) The British climbed up the hill at night and in dense mist. They surprised the small Boer piquet and drove them off the kop at bayonet point. Of the 15 men in the Boer piquet, one was mortally wounded and his grave lies on the hill to this day. Ten British soldiers were wounded in the charge. The surviving Boers retreated down the hill to their camp waking up their fellow Boers by screaming "Die Engelse is op die kop!" (The English are on the hill!). A half-company of British sappers began to entrench the position with a mere 20 picks and 20 shovels (while almost 1,000 soldiers stood around idle) and Woodgate notified Warren of the successful capture of the hilltop. As dawn broke, the British discovered that they held only the smaller and lower part of the hilltop of Spioen Kop, while the Boers occupied higher ground on three sides of the British position. The British had no direct knowledge of the topography of the summit and the darkness and fog had compounded the problem. Furthermore, the British trenches were inadequate for all defensive purposes. Because the summit of the kop was mostly hard rock, the trenches were at most deep and provided an exceptionally poor defensive position – the British infantry in the trenches could not see over the crest of the plateau and the Boers were able to fire down the length of the crescent-shaped trench from the adjacent peaks. 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.
