A probable estimate of the opposing forces places the Boers at 15,000, the British at 11,000.

No certainty can as yet be predicated for the Boer numbers, which depend upon the enemy's calculations, but that they were decisively superior is scarcely doubtful.
After {p.164} considering the problem before him, Methuen concluded that a turning movement was inexpedient.

He could not, on the left, follow the railroad, for that was commanded on both sides.

He could not, on the right, pass between Magersfontein and the Modder, for the bushy ground would prevent his artillery from helping him to its full power, and might even place it in danger of capture.

If he deflected still more to the right, crossing the river, he would have to recross in the face of a force superior to his own in numbers and mobility.
Moreover, in a circuit requiring time, he was hampered by the lack of transport which then fettered all British movements.
