It was well that this was so, for on the 8th of December Commandant Prinsloo, of the Orange Free State, with a thousand horsemen and two light seven-pounder guns, appeared suddenly at Enslin and vigorously attacked the two companies of the Northampton Regiment who held the station. At the same time they destroyed a couple of culverts and tore up three hundred yards of the permanent way. For some hours the Northamptons under Captain Godley were closely pressed, but a telegram had been despatched to Modder Camp, and the 12th Lancers with the ubiquitous 62nd Battery were sent to their assistance. The Boers retired with their usual mobility, and in ten hours the line was completely restored.
Reinforcements were now reaching the Modder River force, which made it more formidable than when it had started. A very essential addition was that of the 12th Lancers and of G battery of Horse Artillery, which would increase the mobility of the force and make it possible for the General to follow up a blow after he had struck it. The magnificent regiments which formed the Highland Brigade--the 2nd Black Watch, the 1st Gordons, the 2nd Seaforths, and the 1st Highland Light Infantry had arrived under the gallant and ill-fated Wauchope. Four five-inch howitzers had also come to strengthen the artillery. At the same time the Canadians, the Australians, and several line regiments were moved up on the line from De Aar to Belmont. It appeared to the public at home that there was the material for an overwhelming advance; but the ordinary observer, and even perhaps the military critic, had not yet appreciated how great is the advantage which is given by modern weapons to the force which acts upon the defensive. With enormous pains Cronje and De la Rey were entrenching a most formidable position in front of our advance, with a confidence, which proved to be justified that it would be on their own ground and under their own conditions that in this, as in the three preceding actions, we should engage them.
On the morning of Saturday, December 9th, the British General made an attempt to find out what lay in front of him amid that semicircle of forbidding hills. To this end he sent out a reconnaissance in the early morning, which included G Battery Horse Artillery, the 9th Lancers, and the ponderous 4.7 naval gun, which, preceded by the majestic march of thirty-two bullocks and attended by eighty seamen gunners, creaked forwards over the plain. What was there to shoot at in those sunlit boulder-strewn hills in front? They lay silent and untenanted in the glare of the African day. In vain the great gun exploded its huge shell with its fifty pounds of lyddite over the ridges, in vain the smaller pieces searched every cleft and hollow with their shrapnel. No answer came from the far-stretching hills. Not a flash or twinkle betrayed the fierce bands who lurked among the boulders. The force returned to camp no wiser than when it left.
There was one sight visible every night to all men which might well nerve the rescuers in their enterprise. Over the northern horizon, behind those hills of danger, there quivered up in the darkness one long, flashing, quivering beam, which swung up and down, and up again like a seraphic sword-blade. It was Kimberley praying for help, Kimberley solicitous for news. Anxiously, distractedly, the great De Beers searchlight dipped and rose. And back across the twenty miles of darkness, over the hills where Cronje lurked, there came that other southern column of light which answered, and promised, and soothed. 'Be of good heart, Kimberley. We are here! The Empire is behind us. We have not forgotten you. It may be days, or it may be weeks, but rest assured that we are coming.'
About three in the afternoon of Sunday, December 10th, the force which was intended to clear a path for the army through the lines of Magersfontein moved out upon what proved to be its desperate enterprise. The 3rd or Highland Brigade included the Black Watch, the Seaforths, the Argyll and Sutherlands, and the Highland Light Infantry.
