Some difficulty in drawing and loading up ammunition delayed the start of the column, which under the command of Carleton was to secure the left flank of the operations; and fearing that daylight on October 30 would find his vulnerable force still on the march he determined soon after midnight to halt short of Nicholson's Nek, from which he was then two miles distant. He had succeeded in passing through the enemy's picket line, and was perhaps not justified in discontinuing his advance, although his instructions were to take Nicholson's Nek only "if possible." But an error of judgment made by a commanding officer on a dark night in a strange country acting under instructions which left him a free hand must not be judged severely, and had it not been for a disaster which could not be foreseen, he would probably have been commended for his prudence. Kainguba Hill, which rises on the left of the road to Nicholson's Nek, seemed to offer a suitable stage on the journey and towards it the column was diverted. While the men were climbing the steep and stony hillside a panic suddenly seized the transport mules. It may have been a spontaneous emotion, or it may have originated in an alarm raised by the Boers who were holding the crest. The animals stampeded down the slope, and carrying with them not only the reserve ammunition but also the signalling equipment, the water carts, and the component parts of the mountain artillery, charged through the rear of the column. The timely exertions of the officers checked the general scare that was imminent; and with the exception of a few score of infantry men and gunners the column reached the summit before daybreak, having lost almost everything needed for a successful occupation of it. Misfortune continued relentlessly to pursue the column. A position was taken up on the hill on the supposition that it could only be attacked from the south, but at daylight C. de Wet, who here came upon the stage which afterwards he often filled so effectively, threatened it from the north with a Free State commando. A gesture made by an officer in order to attract attention was interpreted as a signal to retire; another officer thinking that his company was left alone on the summit, though it was in fact within seventy yards of an occupied sangar, raised the white flag; and almost at the same moment a bugle sounded the Cease Fire. Neither the white flag nor the bugle call was authorized by Carleton; but a glance at the situation showed him that they could not be repudiated and after a gallant struggle to maintain an indefensible position he surrendered. Nearly a thousand men were led away into captivity.
