The last man to leave Ladysmith was French. He was ordered to Capetown to meet Buller, who was persuaded by his report on the situation that White's force was insufficient to keep Natal from being overrun, and that the worst might be feared. The escape of French, by a margin of a few minutes only, made him available for employment in an arena more suited to his capacity than a besieged town; and his subsequent good work in the Cape Colony, south of the Orange River, and during the advance on Kimberley and Bloemfontein, showed how ill the fortune of war served the Boers, when they just failed to capture the train which was taking out of their clutches the soldier who was to relieve Kimberley and head off Cronje at Paardeberg before the relief of Ladysmith was effected. White has been blamed for keeping the whole of his strong force of cavalry in Ladysmith. He had with him four regiments of regular cavalry besides five irregular colonial corps. For the space of three months the action of the British Army was hampered by the absence of the mounted troops interned in Ladysmith and engaged in garrison duties, until at last the horses were either killed for food, or, when forage was exhausted, turned out on the bare veld under the enemy's fire, to support themselves as they could. White justified, or it may be, excused, his retention of the cavalry, by its mobility, which virtually increased the effective strength of the garrison, and enabled him to reinforce rapidly any threatened section of the defence, as for example, during the attack on Caesar's Camp. It is no doubt arguable that cavalry was more useful within the lines of investment than it would have been, if squandered over the whole area of the concurrent operations elsewhere; and if so, the limits of its tactical employment have been considerably extended.[31] White's force, which numbered about 13,000 men, occupied a perimeter of fourteen miles on the hills and kopjes nearest to the town, and was enveloped by an outer perimeter of thirty six miles held by 23,000 Boers. The positions N.E. of the Klip River were occupied by the Transvaalers, and the opposite semi-circle by the Free Staters.
