Various projects for the further movement upon Kimberley had been weighed and found wanting. A purely frontal attack upon the kopjes between Langeberg and Magersfontein Hill involved the crossing of a wide extent of open and level ground, with the danger of a counter-attack by the enemy from the low ridge held by the left wing of Cronje's army. To the west of Langeberg farm the country was so waterless as to preclude any attempt in that direction. A flank march up the Modder river to Brown's Drift, and thence to Abon's Dam, about 16 miles N.E. of Jacobsdal, seemed feasible, for the British column would turn the works of Magersfontein and then fall upon the eastern flank of Spytfontein, the northern of the two lines of heights which lay athwart the railway between the Modder and Kimberley. But before the relieving column could thus swing clear of Magersfontein and strike off thirteen or fourteen miles to the eastward through a country cut up by wire fences, the consequent exposure of Modder River camp, with all its accumulation of stores and its newly-restored railway bridge, had to be taken into account. Lord Methuen considered its safety, and that of the line of communication along the railway to the nearest post at Honey Nest Kloof, essential to his enterprise. Now the adequate defence of the station and this section of the railway required a far larger detachment than he could spare from his division engaged in making a flank march and an attack on Spytfontein. The idea of assaulting the left flank of the Boers was discussed, but abandoned, because it was thought that the bush-covered ground would diminish the effect of the artillery and cause an undue loss of life among the infantry. Therefore, it was finally decided to carry the heights of Magersfontein, and after their occupation and entrenchment to make a turning movement against the left flank of the Spytfontein range. The tactics of Belmont were to be repeated. After a vigorous bombardment of the hill of Magersfontein in the late afternoon of the 10th, the Highland brigade was to march at night to its foot, and at dawn on the 11th attack this, the key of Cronje's position. [Sidenote: The plan finally chosen for Dec. 10th night attack.]
