During the ten days that passed peacefully after the British retreat from the positions beyond Trichardt's Drift, Sir Redvers Buller's force was strengthened by the arrival of a battery of Horse Artillery, two powerful siege guns, two squadrons of the 14th Hussars, and drafts for the Infantry battalions, amounting to 2,400 men. Thus not only was the loss of 1,600 men in the five days' fighting round Spion Kop made good, but the army was actually a thousand stronger than before its repulse. Good and plentiful rations of meat and vegetables were given to the troops, and their spirits were restored by the General's public declaration that he had discovered the key to the enemy's position, and the promise that within a week from the beginning of the impending operation Ladysmith should be relieved. The account of the straits to which the gallant garrison was now reduced by famine, disease, and war increased the earnest desire of officers and men to engage the enemy and, even at the greatest price, to break his lines. In spite of the various inexplicable features which the actions of Colenso and Spion Kop presented, the confidence of the army in Sir Redvers Buller was still firm, and the knowledge that he himself would personally direct the operations, instead of leaving their conduct to a divisional commander, gave general satisfaction and relief. On the afternoon of February 4 the superior officers were made acquainted with the outlines of the plan of action to be followed. The reader will, perhaps, remember the description in a former letter of the Boer position before Potgieter's and Trichardt's Drift as a horizontal note of interrogation, of which Spion Kop formed the centre angle--/\. The fighting of the previous week had been directed towards the straight line, and on the angle. The new operation was aimed at the curve. The general scheme was to seize the hills which formed the left of the enemy's position and roll him up from left to right. It was known that the Boers were massed mainly in their central camp behind Spion Kop, and that, as no demonstration was intended against the position in front of Trichardt's Drift, their whole force would be occupying the curve and guarding its right flank. The details of the plan were well conceived. The battle would begin by a demonstration against the Brakfontein position, which the Boers had fortified by four tiers of trenches, with bombproof casemates, barbed wire entanglements, and a line of redoubts, so that it was obviously too strong to be carried frontally. This demonstration would be made by Wynne's Brigade (formerly Woodgate's), supported by six batteries of Artillery, the Howitzer Battery, and the two 4.7-inch naval guns. These troops crossed the river by the pontoon bridge at Potgieter's on the 3rd and 4th, relieving Lyttelton's Brigade which had been in occupation of the advanced position on the low kopjes.
