As to the disposition of these troops a difference of opinion broke out between the ruling powers in Natal and the military chiefs at the spot. Prince Kraft has said, 'Both strategy and tactics may have to yield to politics '; but the political necessity should be very grave and very clear when it is the blood of soldiers which has to pay for it. Whether it arose from our defective intelligence, or from that caste feeling which makes it hard for the professional soldier to recognise (in spite of deplorable past experiences) a serious adversary in the mounted farmer, it is certain that even while our papers were proclaiming that this time, at least, we would not underrate our enemy, we were most seriously underrating him. The northern third of Natal is as vulnerable a military position as a player of kriegspiel could wish to have submitted to him. It runs up into a thin angle, culminating at the apex in a difficult pass, the ill-omened Laing's Nek, dominated by the even more sinister bulk of Majuba. Each side of this angle is open to invasion, the one from the Transvaal and the other from the Orange Free State. A force up at the apex is in a perfect trap, for the mobile enemy can flood into the country to the south of them, cut the line of supplies, and throw up a series of entrenchments which would make retreat a very difficult matter. Further down the country, at such positions as Ladysmith or Dundee, the danger, though not so imminent, is still an obvious one, unless the defending force is strong enough to hold its own in the open field and mobile enough to prevent a mounted enemy from getting round its flanks. To us, who are endowed with that profound military wisdom which only comes with a knowledge of the event, it is obvious that with a defending force which could not place more than 12,000 men in the fighting line, the true defensible frontier was the line of the Tugela. As a matter of fact, Ladysmith was chosen, a place almost indefensible itself, as it is dominated by high hills in at least two directions.
