When Lyttelton became aware that the enemy had been expelled, he proposed to avail himself of the success without delay, and push on to the Nek and Monte Cristo, while Warren's Vth Division attacked Green Hill; but Buller objected to an advance which could not be completed before nightfall. Lyttelton bivouacked S.W. of the ridge and Dundonald on the detached hill at its northern end. During the night, field guns were brought up the slopes and with much difficulty emplaced in a position from which shell fire could be directed on Monte Cristo. If the movement of the day was not remarkable for speed and enterprise, it was at least directed with skill and without excessive caution; and Dundonald showed that his military spirit had not been chilled by previous rebuffs, one of them administered almost on the spot where he was now in activity. At daylight on February 18, the movement was resumed, the immediate objective being the capture of Monte Cristo and Green Hill. One brigade was sent through the Nek on to the eastward slopes of Monte Cristo, while the other attacked the hill from the south. With the help of the ever-ready Dundonald the IInd Division established itself on the main hill of the ridge early in the afternoon. The Fusilier Brigade of the Vth Division was meanwhile acting in support; and advancing as soon as Monte Cristo was seen to be occupied, easily took hold of Green Hill. The enemy was now expelled from all the positions commanding the proposed line of advance over the Nek, and was retreating westward towards the positions near the right bank of the Tugela, but no attempt was made to pursue him. The motto of Buller's Army was _festina lente_ and its track towards Ladysmith was in zigzag. On the following day Hlangwhane was occupied by the British troops, and before noon on February 20, all the Boers had withdrawn to the left bank of the Tugela, and Buller was favourably placed for the advance by way of the Klip River on Bulwana. A reconnaissance, however, caused him to change his mind and to resume the movement at an acute angle by doubling back towards Hlangwhane and crossing the river by a pontoon bridge west of the hill. His new plan was to capture a position between the Onderbroek and Langewacht Spruits, which appeared from a distance to be one hill, but which in reality was two, Wynne's Hill and Horseshoe Hill, which were separated by a donga. On the morning of February 21 he signalled his intentions to White, saying that he thought he had "only a rearguard before him"[29] and that he hoped to be in Ladysmith next day. After the capture of Monte Cristo and the Hlangwhane position, some of the commandos seem to have trekked away towards the north, and even Botha for a time appears to have lost heart and to have suggested to Joubert that the siege of Ladysmith should be raised. The Boer leaders had already, like King Arthur, Heard the steps of Modred in the west,
