The frontal attack was initiated by Kelly-Kenny with the 13th Brigade under C. Knox, the 18th Brigade having been detached to support Hannay's flank attack. The main body of the Boers was north of the river, but strong detachments held the left-bank dongas. Colvile was dealing with a demonstration against Paardeberg Drift when an oral message from Kitchener reached him, which he interpreted as an order to go to Knox's assistance with his Division, which was thus withdrawn from the flank and lent to the frontal attack. He was doubtfully carrying out what he believed to be his instructions when an order reached him to send the 19th Brigade, under Smith-Dorrien, across the river. A few companies of his Highland Brigade succeeded in establishing themselves on the right bank, and Knox drove the enemy out of the left-bank dongas, but was forbidden by Kelly-Kenny to cross the river, as the enemy was too strongly posted. The frontal attack was spent, but the troops remained on their ground until the approach of night released them. Two miles S.E. of Vendutie Drift, a hill, to which the name of Kitchener's Kopje was afterwards given, rises out of the veld. In the tactics of the assault on the laager, it was not a position of much importance, but in the Paardeberg drama it was a striking scene. The detachment of infantry which Kelly-Kenny sent early in the day to occupy it had been withdrawn without his knowledge by some wandering staff officer, who thought he had found a better use for the little garrison, and replaced by a few mounted men. These, while watching the progress of the fight, and perhaps regretting that they were not taking a more active part in it, were suddenly called upon to defend themselves. De Wet, with two guns and 600 men, had arrived from Koffyfontein at the opportune moment of the crisis of the flank attacks. He soon carried the kopje, and when at 4.30 p.m. he opened fire, the shells which he pitched into the VIth Division baggage and artillery were the first intimation of his intervention received by the Head Quarter Staff, absorbed in their attack on the laager; and for the second time the troops were called away from the work in hand, to deal with an unexpected attack from the rear, and the dwindling hope of carrying Cronje's position before nightfall passed away.
