A new pontoon bridge was thrown at the angle of the river a mile below Potgieter's, the purpose of which seemed to be to enable the frontal attack to be fully supported. While the Artillery preparation of the advance against Brakfontein and Wynne's advance were going on, Clery's Division (consisting of Hart's Brigade and Hildyard's) and Lyttelton's Brigade were to mass near the new pontoon bridge (No. 2), as if about to support the frontal movement. When the bombardment had been in progress for two hours these three brigades were to move, not towards the Brakfontein position, but eastwards to Munger's Drift, throw a pontoon bridge covered first by one battery of Field Artillery withdrawn from the demonstration, secondly by the fire of guns which had been dragged to the summit of Swartkop, and which formed a powerful battery of fourteen pieces, viz., six 12-pounder long range naval guns, two 15-pounder guns of the 64th Field Battery, six 9-pounder mountain guns, and lastly by the two 50-pounder siege guns. As soon as the bridge was complete Lyttelton's Brigade would cross, and, ignoring the fire from the Boer left, extended along the Doornkloof heights, attack the Vaal Krantz ridge, which formed the left of the horseshoe curve around the debouches of Potgieter's. This attack was to be covered on its right by the guns already specified on Swartkop and the 64th Field Battery, and prepared by the six artillery batteries employed in the demonstration, which were to withdraw one by one at intervals of ten minutes, cross No. 2 pontoon bridge, and take up new positions opposite to the Vaal Krantz ridge. If and when Vaal Krantz was captured all six batteries were to move across No. 3 bridge and take up positions on the hill, whence they could prepare and support the further advance of Clery's Division, which, having crossed, was to move past Vaal Krantz, pivot to the left on it, and attack the Brakfontein position from its left flank. The 1st Cavalry Brigade under Burn-Murdoch (Royals, 13th and 14th Hussars, and A Battery R.H.A.) would also cross and run the gauntlet of Doornkloof and break out on to the plateau beyond Clery's Division. The 2nd Cavalry Brigade (South African Light Horse, Composite Regiment, Thorneycroft's, and Bethune's Mounted Infantry, and the Colt Battery) were to guard the right and rear of the attacking troops from any attack coming from Doornkloof. Wynne was to co-operate as opportunity offered. Talbot Coke was to remain in reserve. Such was the plan, and it seemed to all who heard it good and clear. It gave scope to the whole force, and seemed to offer all the conditions for a decisive trial of strength between the two armies.
