The Natal Field Force was now confronted with the bulk of the Boer commandoes, whose strength was vastly superior to its own, and whose courage was generally acknowledged to be splendid. The Dutch have ever a stoical stolidity which serves them in the hour of need as does the bulldog tenacity of the Briton, and therefore "those who knew" were not without apprehension in regard to the upshot of hostilities. It was plain to all who were in any way familiar with previous history and with local conditions that the struggle was likely to be both prolonged and bloody, and they urged on the attention of those at home the need of reinforcements. Yet the soldiers, particularly those who had recently arrived, were light-hearted and confident, full of satisfaction to be let loose from their hencoops in the ships, and keen to try conclusions with the Boers. At Ladysmith the state of affairs was becoming more and more complicated, and the invasion of the Free Staters into Cape Colony was now an accomplished fact. The enemy's tactics everywhere were acknowledged to be excellent, and where tactics failed tricks succeeded. The Boer dodges, though scarcely honourable, might be described by the Americans as "cute." For instance, an enterprising officer of the Transvaal artillery conceived the idea of utilising the flag of truce in a new and original fashion. Disguised as an ambulance driver, he arrived at Ladysmith, and improved the occasion by observing the effects of Boer artillery fire on the town. The use of the white flag by the enemy was now beginning to be distrusted, for daily evidences of treachery were forthcoming. As one correspondent said in writing home of the subject, "Its advantages they seem to construe in too liberal a spirit, but of its obligations on the men who hoist it they do not appear to be aware." As in old times, they tried to use the white flag to assist them in going from cover to cover, or to create delay while guns were being adjusted in more convenient positions. Nor was this all. A wounded Boer accepted water with one hand from a British soldier, while he shot him with the other, and numberless accounts of dastardly deeds of a similar nature were reported and authenticated.
