Some say that had it not been for the action of the artillery commander in taking a whole brigade division--three batteries--up at a gallop to within 700 yards of the enemy's trenches, the day might still have been ours. The valiant Irishmen would still have pursued their risky advance. Others declared that the want of proper scouting caused the whole fiasco, and that all the pluck of the Irish Brigade was so much heroism wasted. They had no information relative to the intrenchments of the place to be attacked by them, nor any conception of the strength of the opposition they were liable to meet. No scouts appear to have discovered the position of the ford by which they were ordered to cross, or the nearness of the enemy to that point, and consequently the brigade marched in quarter-column into the very jaws of death, only deploying when shells had already begun to burst in their midst. Like the guns of the Royal Artillery, they found themselves before they were prepared in the midst of a close and deadly fusillade--the more deadly and unnerving because on the clearest of days not a whiff of smoke betrayed the quarters from whence the murderous assaults were coming. [Illustration: MAP SHOWING THE ATTEMPTED PASSAGE OF THE RIVER BY GENERAL BULLER ON DECEMBER 15.] General Barton's brigade, like Hart's and Hildyard's, failed to effect its object. It was found impossible to obtain possession of Hlangwane Hill, which was much more strongly held than it was believed to be. The troops were assailed from thence by such galling shell and rifle fire that they were eventually forced to retire. On the extreme right, the mounted troops, under Lord Dundonald, made a vigorous attack at the Hlangwane Hill, on which was posted the Boer pieces which had wrought such devastation among the British batteries. However, in advancing up the valley, they were outflanked by the Boers, and had eventually to retire under a storm of bullets. The irregulars, for their part, worked splendidly. The South African Horse advanced on the front under a heavy shell fire. Thorneycroft's Horse, the Natal Carabineers, the Imperial Light Horse, and the Mounted Infantry at the same time attempted the flanking attack; but the Boer lines, which ran along some high ground to the right of the flanking party, defeated their best efforts. Owing to the bad light, and to the fact that the Boers used smokeless powder, their fire failed to reveal their position, and the discomfort of the attacking party was considerable.
