On February 9th the movements were started which transferred the greater part of the force from the extreme left to the centre and right. By the 11th Lyttelton\'s (formerly Clery\'s) second division and Warren\'s fifth division had come eastward, leaving Burn Murdoch\'s cavalry brigade to guard the Western side. On the 12th Lord Dundonald, with all the colonial cavalry, two battalions of infantry, and a battery, made a strong reconnaissance towards Hussar Hill, which is the nearest of the several hills which would have to be occupied in order to turn the position. The hill was taken, but was abandoned again by General Buller after he had used it for some hours as an observatory. A long-range action between the retiring cavalry and the Boers ended in a few losses upon each side.
What Buller had seen during the hour or two which he had spent with his telescope upon Hussar Hill had evidently confirmed him in his views, for two days later (February 14th) the whole army set forth for this point. By the morning of the 15th twenty thousand men were concentrated upon the sides and spurs of this eminence. On the 16th the heavy guns were in position, and all was ready for the advance.
Facing them now were the formidable Boer lines of Hlangwane Hill and Green Hill, which would certainly cost several thousands of men if they were to take them by direct storm. Beyond them, upon the Boer flank, were the hills of Monte Christo and Cingolo, which appeared to be the extreme outside of the Boer position. The plan was to engage the attention of the trenches in front by a terrific artillery fire and the threat of an assault, while at the same time sending the true flank attack far round to carry the Cingolo ridge, which must be taken before any other hill could be approached.
On the 17th, in the early morning, with the first tinge of violet in the east, the irregular cavalry and the second division (Lyttelton\'s) with Wynne\'s Brigade started upon their widely curving flanking march. The country through which they passed was so broken that the troopers led their horses in single file, and would have found themselves helpless in face of any resistance. Fortunately, Cingolo Hill was very weakly held, and by evening both our horsemen and our infantry had a firm grip upon it, thus turning the extreme left flank of the Boer position. For once their mountainous fortresses were against them, for a mounted Boer force is so mobile that in an open position, such as faced Methuen, it is very hard and requires great celerity of movement ever to find a flank at all. On a succession of hills, however, it was evident that some one hill must mark the extreme end of their line, and Buller had found it at Cingolo. Their answer to this movement was to throw their flank back so as to face the new position.
Even now, however, the Boer leaders had apparently not realised that this was the main attack, or it is possible that the intervention of the river made it difficult for them to send reinforcements. However that may be, it is certain that the task which the British found awaiting them on the 18th proved to be far easier than they had dared to hope. The honours of the day rested with Hildyard\'s English Brigade (East Surrey, West Surrey, West Yorkshires, and 2nd Devons). In open order and with a rapid advance, taking every advantage of the cover – which was better than is usual in South African warfare – they gained the edge of the Monte Christo ridge, and then swiftly cleared the crest. One at least of the regiments engaged, the Devons, was nerved by the thought that their own first battalion was waiting for them at Ladysmith. The capture of the hill made the line of trenches which faced Buller untenable, and he was at once able to advance with Barton\'s Fusilier Brigade and to take possession of the whole Boer position of Hlangwane and Green Hill. It was not a great tactical victory, for they had no trophies to show save the worthless debris of the Boer camps. But it was a very great strategical victory, for it not only gave them the whole south side of the Tugela, but also the means of commanding with their guns a great deal of the north side, including those Colenso trenches which had blocked the way so long. A hundred and seventy killed and wounded (of whom only fourteen were killed) was a trivial price for such a result. At last from the captured ridges the exultant troops could see far away the haze which lay over the roofs of Ladysmith, and the besieged, with hearts beating high with hope, turned their glasses upon the distant mottled patches which told them that their comrades were approaching.
By February 20th the British had firmly established themselves along the whole south bank of the river, Hart\'s brigade had occupied Colenso, and the heavy guns had been pushed up to more advanced positions. The crossing of the river was the next operation, and the question arose where it should be crossed. The wisdom which comes with experience shows us now that it would have been infinitely better to have crossed on their extreme left flank, as by an advance upon this line we should have turned their strong Pieters position just as we had already turned their Colenso one. With an absolutely master card in our hand we refused to play it, and won the game by a more tedious and perilous process. The assumption seems to have been made (on no other hypothesis can one understand the facts) that the enemy were demoralised and that the positions would not be strongly held. Our flanking advantage was abandoned and a direct advance was ordered from Colenso, involving a frontal attack upon the Pieters position.
On February 21st Buller threw his pontoon bridge over the river near Colenso, and the same evening his army began to cross. It was at once evident that the Boer resistance had by no means collapsed. Wynne\'s Lancashire Brigade were the first across, and found themselves hotly engaged before nightfall. The low kopjes in front of them were blazing with musketry fire. The brigade held its own, but lost the Brigadier (the second in a month) and 150 rank and file. Next morning the main body of the infantry was passed across, and the army was absolutely committed to the formidable and unnecessary enterprise of fighting its way straight to Ladysmith.
The force in front had weakened, however, both in numbers and in morale. Some thousands of the Freestaters had left in order to defend their own country from the advance of Roberts, while the rest were depressed by as much of the news as was allowed by their leaders to reach them. But the Boer is a tenacious fighter, and many a brave man was still to fall before Buller and White should shake hands in the High Street of Ladysmith.
The first obstacle which faced the army, after crossing the river, was a belt of low rolling ground, which was gradually cleared by the advance of our infantry. As night closed in the advance lines of Boers and British were so close to each other that incessant rifle fire was maintained until morning, and at more than one point small bodies of desperate riflemen charged right up to the bayonets of our infantry. The morning found us still holding our positions all along the line, and as more and more of our infantry came up and gun after gun roared into action we began to push our stubborn enemy northwards. On the 21st the Dorsets, Middlesex, and Somersets had borne the heat of the day. On the 22nd it was the Royal Lancasters, followed by the South Lancashires, who took up the running. It would take the patience and also the space of a Kinglake in this scrambling broken fight to trace the doings of those groups of men who strove and struggled through the rifle fire. All day a steady advance was maintained over the low kopjes, until by evening we were faced by the more serious line of the Pieter\'s Hills. The operations had been carried out with a monotony of gallantry. Always the same extended advance, always the same rattle of Mausers and clatter of pom-poms from a ridge, always the same victorious soldiers on the barren crest, with a few crippled Boers before them and many crippled comrades behind. They were expensive triumphs, and yet every one brought them nearer to their goal. And now, like an advancing tide, they lapped along the base of Pieter\'s Hill. Could they gather volume enough to carry themselves over? The issue of the long-drawn battle and the fate of Ladysmith hung upon the question.
