As an abstract military question there need be no hesitation in saying that the advance through the Orange Free State was in principle the correct plan, even under the existing conditions, as far as these are accurately known. But conditions are never accurately known to outsiders so immediately after a war. Even the hard bottom facts which ultimately appear, the residuum left after full publicity, and discussion, and side lights from all sources have done their work, do not correctly reproduce the circumstances as present to the mind of the general officer who decides. What is known now was doubtful then; what now is past and certain, was then future and contingent; what this and that subordinate, this force and that force could endure and would endure we now know, but who could surely tell six months ago? Who, whatever his faith in the heroism and patience of the garrisons, believed in December, 1899, that Ladysmith and Kimberley and Mafeking could hold out, without relief, as long as they did? What therefore, between the known uncertainties of the past and the certainly imperfect information of the present, we, who had not the responsibilities of decision, may modestly refrain from positively judging the particular decision, even by the generally sound principles which commonly govern such cases. Warfare is an art, not a science; it knows no unvarying laws, and possesses neither specifics nor panaceas.
Whatever the reason, the decision was reached to attempt simultaneously the relief of Kimberley and of Ladysmith. It is with the former, which also was first in order of time, that we now have immediately to do. This advance had begun, had reached its furthest limit, had been brought to a standstill, and so had failed, before the clash of arms at Colenso, on December 15, signalized the opening of the campaign for the relief of Ladysmith. This priority was naturally to be expected; for not only was Cape Town the first port of arrival from England, but the much larger number of the besiegers at Ladysmith made a much longer time necessary to accumulate the force adequate to contend successfully against them. The details of the assembling of Methuen's division at Orange River Station need not detain us. The 2,500 men there in the first week of November had been increased by November 19 to nearly 10,000, and began to advance on the 21st. It will be well, however, to say a word about their objective, Kimberley, its conditions, its defences, and its defenders, as well as about the country through which runs the railroad that marks the general line of Methuen's proposed operation.
Lieutenant-Colonel Kekewich, who had been ordered to command the forces in Kimberley, had arrived there on the 13th of September. Already portions of the Transvaal levies were out, "on commando," as the Boer phrase is, moving on the Free State side of the boundary line; and many reasonably authenticated rumours were heard of intentions to destroy the railroad bridges—notably over the Modder and Orange Rivers—south of the place, as well as others north of it. The guard of the road generally was then in charge of a mounted body called the Cape Police, detachments of which watched the bridges. Political and other considerations prevented immediate steps from being taken to fortify the town, but plans were matured, and information concerning the surrounding country had already been procured by subordinate officers, whose arrival had preceded that of Kekewich. On the 18th of September, construction of defence works began, reports of movements by the burghers of the Free State as well as by Transvaalers being received, and arousing apprehension of a sudden attack. On the 27th of September, an officer of the garrison, by personal observation at Boshof in the Free State, ascertained that the burghers of the latter had been ordered out. The works were then pressed forward, and the formation of citizens into town guards already planned, was begun; 1,156 combatant members being enrolled, and placed under drill by non-commissioned officers of the regular battalion in garrison. The Boer forces continued to approach Kimberley, and on October 4, a week before war began, advanced bodies were within twelve miles. By October 7 the earthworks were so far forward that Kekewich considered the place practically safe against any attempt on the part of the enemy to rush it suddenly.
When the ultimatum expired, October 11, the garrison proper consisted of 570 Imperial and 630 colonial troops, for the defence of an unwalled town which contained 40,000 inhabitants and, being built in rambling fashion, had a very long circuit—about eleven miles—to be guarded. The ready co-operation of the citizens in military duty, both those already belonging to volunteer bodies and those not previously organised, but now enrolling themselves for the purpose, alone made the defence possible. From them, particularly, was formed a corps of irregular horse, which filled the want of mounted troops that at first was severely felt. Colonel Kekewich, recognising the enemy's overpowering superiority of numbers, rapidly drew into Kimberley all the outlying forces of every character under his command.
Although deeply concerned for the safety of the Modder River bridge, upon which in a measure would depend the advance of a relief column, "I was most anxious," he says, "that no disposition of troops made by me should give the enemy a chance of scoring a first success, even where the smallest body of British troops might be concerned. Taking into consideration that the enemy would probably not regulate his movements in accordance with the dictates of sound strategy, that he was in possession of mobile artillery in my immediate neighbourhood, I felt that if I had detached a small body of troops, necessarily without artillery, which it was not in my power to support from Kimberley, the enemy would in all probability concentrate very superior numbers, with artillery, against the small British post, and endeavour to destroy the troops composing the same. It was principally for this reason that I determined to concentrate all my available forces, including the Cape Police, at the point of greatest importance in my command—Kimberley."
The inference of Colonel Kekewich as to the Boers' strategy was as accurate as his general action was militarily judicious. The concentration and development of his resources not merely deterred the enemy from assault, but detained them there in force, to the neglect of matters elsewhere much more urgently worthy of their efforts. The gain of Kimberley, had they gained it, would have been poor compensation for the daily increasing solidity of the still weak British grasp on the central positions outlined by De Aar, Orange River and Naauwport. This absorption of the Boers' attention by Kimberley was maintained by frequent sorties of the garrison, in every direction, which at an early period of the siege became possible through the ready facility with which the citizens were converted into irregular mounted troops. "It will be observed," wrote Kekewich, "that portions of the mounted corps were employed on every occasion" of the continued sallies in greater or less force, especially at the period of Methuen's advance.
At the same time the enemy was preparing to bombard, and was busily engaged in taking possession, by small bodies of from 100 to 250 men, of the undefended towns and villages in Griqualand West—the thinly peopled district to the west of Kimberley. This pleasant but useless pastime occupied them agreeably, and diverted them from molesting the British at Orange River and De Aar.
"My general plan for the defence of Kimberley," says Kekewich in his report, "was based on the principle of always keeping the enemy on the move, and constantly in fear of an attack from an unexpected quarter. Later, when the advance of the relief column from the Orange River commenced, and I was put in possession of information concerning the probable date of its arrival in Kimberley, I adopted such measures as I hoped would cause the retention of a large force of the enemy in my immediate neighbourhood, and thus enable the relief column to deal with the Boer force in detail. It was with these objects that the numerous sorties and demonstrations in force were made by portions of the garrison of Kimberley."
Such continual offensive action is of the essence of dexterous defence, especially when designed in support of movements elsewhere occurring. It is not surprising, therefore, that Lord Roberts, in forwarding Kekewich's report, comments that "the greatest credit is due him for his able dispositions, for his rapid organisation of an auxiliary force, and for the tact, judgment, and resolution which he displayed throughout the siege." This admirable service was performed at a loss of 38 killed and 133 wounded, of all the troops employed from the beginning of the investment to the day of relief.
Orange River, where Methuen's relief force was assembling, is seventy miles from Kimberley. The country between is part of the great inland plateau, in general contour rolling, but with frequent stony hills, which locally have the name of kopjes, now become so familiar. These kopjes are of varying heights, from fifty to five hundred feet, and consist mainly of large boulders, with, however, a plentiful sprinkling of smaller rocks not too heavy for handling. The steepness and roughness of the surface make climbing a matter of hands as well as of feet, and are therefore a source of particular difficulty and exposure to an assailant; while, on the other hand, the broken heaps of huge stones afford to the defence much natural protection, and can be further improved by building shelter places, which it was the habit of the Boer to do, forming semicircular breastworks. In this way, with natural and artificial cover, was obtained a strong line of defence, depending in extent upon the length and formation of the kopje.
