The turning point of the war, however, was reached when, on January 10th, 1900, Roberts took charge of hostilities, and began his famous march to Pretoria. A month after his arrival at Cape Town, Lord Roberts and his staff went north, his movements being shrouded in mystery. On the 9th February, 1900, he took over command at Modder River camp, and within three days his great movement was begun. The Highland Brigade, under the bravest of soldiers, Major-General Macdonald, were engaged with the enemy to the west of the railway, this being to attract the enemy’s attention from the preparation for a greater event. The intention was to make straight to relieve Kimberley. Suddenly the Free State (as it was then) was invaded at various points to the south of Modder River. General French, who had been withdrawn from Colesberg with his cavalry, dashed north, brushing aside or ignoring small parties of Boers, who sought to oppose him. The General then swept in a circle round the east of Magersfontein, and after a trying march, Kimberley was reached late in the afternoon of Wednesday, February 14th.

The Boer commandoes had timely warning of the advancing hosts, and, recognising that in the circumstances their position was untenable, the enemy took to flight. There was very little fighting. The Kimberley garrison moved out when it was apparent that the relief force was at hand, but the enemy did not wait for these. The garrison was too late to intercept the retreat, the Boers getting away in the darkness. The Boers’ loss in arms and ammunition was enormous. The first of the besieged towns had been relieved, but not at a cheap price. It was work which cost Britain, from Belmont onwards, 129 officers and 1818 men. The British infantry brigades followed in the wake of General French, and marching north-east, occupied Jacobsdal, the Boer base of supplies.

General Cronje, one of the most stubborn of the Boer generals, whose tactics were typical of his reputed border ancestry, saw that he ran a great risk of being surrounded in his trenches at Magersfontein. There was one loophole of escape—to the east between the rear of the British cavalry and the front of the infantry. Accordingly Cronje warily made towards Bloemfontein by this route. But he was not circumspect enough, and his retreat was soon discovered. British infantry and cavalry were despatched in hot pursuit, and he was brought to bay on the 10th at Paardeberg, in the valley of the Modder River. On that day an attempt to storm the Boer laager failed. The British circled round the doomed Cronje, and day by day the lines of investment were drawn closer. Shot and shell were poured into the camp of the Boers, who, like rabbits, buried themselves in holes in the river bank. Quite a number of Boer commandoes were defeated, but despite this, and the fact that his camp was in flames, and shot and shell were dropping into it like rain, the obstinate Cronje refused to yield. The statement that Cronje was a descendant of the old raiders of Galloway was certainly amply qualified by his tactics throughout. However, on the morning of Majuba Day—27th February—the Canadians, Gordons, and Shropshires dashed forward, and entrenched themselves in a position which commanded the Boer camp. After this, Cronje saw that further resistance was useless, and, with 4000 men, unconditionally surrendered.

It was a small force that was commanded by Cronje as compared with the army of besiegers, and he had held out magnificently. After the battle an examination of the enemy’s position showed this. The whole of the river on both sides was honeycombed with trenches, but such trenches as had never before been used in warfare; they were really underground dwellings, and perfectly secure unless a shell was dropped into the opening above. Straight projecting missiles were bound to fail to have an effect. The condition of the whole laager, and trenches, however, was a frightful one. Every three paces lay dead horses, mules and cattle, polluting the air, and it was no wonder Cronje was forced to surrender at last. The parting between several men and their wives at this stage was extremely heartrending, and both were crying bitterly. The completeness of the capture was the more singular in view of the determined character of the enemy, and it was thought, at the very least, the enemy would destroy their guns and ammunition before surrendering.

The pursuit and capture of the Boers cost Britain no fewer than 98 officers and 1436 men.

Pushing on from Paardeberg, Lord Roberts, on the 7th March, outflanked the Boers at Poplar Grove, compelling them to retreat, and three days later he defeated them at Driefontein. Ex-President Steyn fled from the capital, and on the 13th Lord Roberts took possession, as he himself put it, “by the help of God and the bravery of Her Majesty’s soldiers.” The total casualties, since the army left Modder River, were 2086 officers and men, killed, wounded and missing.

The occupation of Bloemfontein had a wonderful effect on the course of events. The Boers withdrew from northern Cape Colony, and the British forces crossed the Orange River on 15th March. There had been much desultory fighting in this district, and the British losses would amount to about 2000.

While the relief of Ladysmith by General Buller was taking place, Lord Roberts rested at Bloemfontein for six weeks for the purpose of reorganising his transport service, and generally strengthening his forces. This inactivity on the part of the British commander was fully taken advantage of by the Boers, who swept down to the east and south-east of the capital. It was then Lord Roberts decided to check the enemy’s progress, and the battle of Karree was fought, at which the enemy made their last stand between Bloemfontein and Brandfort. Their attitude had become unceasingly aggressive, and if the Free State burghers, who had surrendered to Britain, were to be assured of her ability to protect them, it was necessary to check the raids and incursions in the country immediately north of the capital. Lord Roberts deputed this task to the 7th Division, commanded by Lieutenant-General Tucker, the 1st and 3rd cavalry brigades under General French, and the brigade of mounted infantry under Colonel le Gallais.

At an early hour in the morning the whole force, preceded by a screen of mounted men, moved out of the advance camp in the direction of a ridge which commanded the line of railway north of Modder Bridge. It was known to be occupied and entrenched by an outpost of 1500 Boers. Moving forward over the plain, which the British cavalry had already reconnoitred, General Tucker was soon in front of the enemy’s position. After a stiff fight and attacks from various positions, the object of the advance was fully attained, and the troops bivouacked on the position they had carried. The Boers, however, succeeded in getting away over a flat country with all their guns and waggons.

This was followed by several rather unfortunate mishaps to the British forces at Sanna’s Post and Reddersburg, the latter being particularly noted for a gallant stand by the Royal Irish Rifles against great odds. Three companies of Royal Irish Rifles and two companies of the north regiment of mounted infantry which had been captured by the Boers, were falling back for a position when they were surrounded by over 3000 of the enemy, occupying a kopje. They defended the position for nearly 24 hours, notwithstanding that they were without food or water, and were exposed to the shells of the enemy’s guns. This fight was one of rifles on the Boer side and artillery on the other, and before darkness fell all the gallant British fellows were being led away. General Gatacre, who had been advised of the fighting, hurried to the scene, to arrive two hours late. At this time the whole country was reeking with active spies. As a result of Reddersburg about 600 men were captured. While at Sanna’s Post, another unfortunate mishap, 37 officers and over 500 men were made prisoners. After this came the stiff engagement at Wepener, which lasted several days. An attempt was made to encircle the enemy by the British general, and while the opposing forces received a check, both sides suffered heavy casualties. This attempt at encircling the enemy was not successful.
