The brigade, doing advance-guard to the whole concentration, had crossed the great prairie which lies north of Houwater, and the covering cloud of mounted _eclaireurs_ was already disappearing into the shade of the mountain fastness in front of us. The giant outcrop of volcanic rock which is known as Minie Kloof rises, with that directness peculiar to the vast South African table-land, sheer from a prairie as level as a billiard-table. A succession of rocky flat-topped parallelograms, featureless save for the one sealed pattern of nature's architecture of the veldt. To the nomadic traveller and man of peace, landmarks as barren and bare as the great ironstone belts of Northern Africa, which constrain the power of the unwilling Nile until she surges in angry cataract through such niggard opening as they will allow her. To the man of war, a veritable Gibraltar; a maze of possibilities in defence; a stupendous undertaking in attack, an undertaking which will brook neither error nor miscalculation, and from which nature has eliminated much of the element of chance on the one side to place it to the credit of the other. Of such a kind were our Colenso, Magersfontein, Stormberg, and Spion Kop heights. You at home at your ease, taking in from the map in a second a perfunctory impression of the topography, which it would take a cavalry brigade half a day to verify, talk glibly of turning this position and out-flanking that. Know ye that the lateral problem, which in the pink and green of the atlas would appear so simple, may be for miles a gridiron of parallel and supporting positions. That the well-considered turning movement put in motion at the first streak of dawn may be, and probably will have become, a plain and simple frontal attack by sunrise, through circumstances that no man, not even Napoleon himself, could foresee or control. Then this being given, why not deal leniently with such men as have served you well, and who may be trusted to profit by experience dearly purchased? but the other class, the man who has prostituted the fighting excellence of the British soldier in the shock of war by appealing to the chances of war, without due care and forethought--why, it is your duty to destroy him: your bitterest strictures even will not meet the punishment such a one deserves.
