What Buller had seen during the hour or two which he had spent with his telescope upon Hussar Hill had evidently confirmed him in his views, for two days later (February 14th) the whole army set forth for this point. By the morning of the 15th twenty thousand men were concentrated upon the sides and spurs of this eminence. On the 16th the heavy guns were in position, and all was ready for the advance. Facing them now were the formidable Boer lines of Hlangwane Hill and Green Hill, which would certainly cost several thousands of men if they were to take them by direct storm. Beyond them, upon the Boer flank, were the hills of Monte Christo and Cingolo, which appeared to be the extreme outside of the Boer position. The plan was to engage the attention of the trenches in front by a terrific artillery fire and the threat of an assault, while at the same time sending the true flank attack far round to carry the Cingolo ridge, which must be taken before any other hill could be approached. On the 17th, in the early morning, with the first tinge of violet in the east, the irregular cavalry and the second division (Lyttelton's) with Wynne's Brigade started upon their widely curving flanking march. The country through which they passed was so broken that the troopers led their horses in single file, and would have found themselves helpless in face of any resistance. Fortunately, Cingolo Hill was very weakly held, and by evening both our horsemen and our infantry had a firm grip upon it, thus turning the extreme left flank of the Boer position. For once their mountainous fortresses were against them, for a mounted Boer force is so mobile that in an open position, such as faced Methuen, it is very hard and requires great celerity of movement ever to find a flank at all. On a succession of hills, however, it was evident that some one hill must mark the extreme end of their line, and Buller had found it at Cingolo. Their answer to this movement was to throw their flank back so as to face the new position.
