When the march was resumed another railway was almost immediately encountered. It was in fact the colliery line which had been crossed before the halt and which here curves almost to the extent of a semicircle; but Gatacre believed that he had come upon the main line to Steynsburg and judged that he was now N.W. of the Boer position; while many of the officers in the rear of the column, unaware of the change of plan, imagined that they were approaching it from the S.E. along the Stormberg road originally selected for the advance on which the ambulance and ammunition wagons had already gone astray. The direction of the march was now almost reversed, owing to Gatacre's misapprehension of his position; and at dawn the column unknown to itself reached certain cross roads on Van Zyl's farm which had been fixed upon as the point from which the attack should be delivered; but the locality was not recognized by the staff, and the guides, who seem to have misunderstood the object of the march, conducted the column still deeper into the valley beneath the Kissieberg ridge. Suddenly a shot from the heights startled the errant and plodding column. The Boers had indeed been taken by surprise, but were at once on the alert and the crest line was soon occupied. The column marching in fours halted and turned to the right and, except the leading companies of Irish Rifles, which were formed to the front in order to seize a detached hill at the end of the ridge, sprang up the slope, but were soon baffled by the irregular tiers of krantzes or rock walls on the hill side. The artillery diverged to the left, losing one gun in the donga which ran down the valley, and took post on the detached hill from which the Kissieberg ridge could be shelled. The companies of Irish Rifles, after seizing this hill, passed along the nek which joined it to the ridge and almost won the crest line. Meanwhile the Northumberland Fusiliers and the remaining companies of the Irish Rifles found the task of mounting the encumbered slope beyond their powers, and were soon ordered to fall back into the valley. The artillery noticed the movement, and in order to cover the retreat opened upon Kissieberg; not perceiving in the eastern dazzle of the sun about to rise above the sky line that some of the infantry who had not heard the order to retire were still clinging to the darkened westward hillside, and these were shelled by their own guns. Gatacre, confident of an easy success, had thrown all his infantry into the firing line, and had no reserves to fall back upon to support the companies of the Irish Rifles which were still holding their own on the left flank of the attack. As soon as the troops had crossed the valley to reform on the opposite ridge a new entanglement beset them.
