Sir G. White arrived in Ladysmith on the 11th October. On the 12th telegraphic communication by Harrismith entirely ceased, and the mail train from that town failed to arrive. Early on the 12th a telegram from a post of observation of Natal Carbineers at Acton Homes gave information that a strong column of Boers, with four miles of train, was on the march through Tintwa Pass, the head of it being already across the border; furthermore, that there seemed to be an advance guard concealed in Van Reenen's Pass. Sir G. White prepared to strike instantly; but a British detachment which reached Dewdrop next day saw the Boer vanguard, halted in the mouth of Tintwa Pass, and as previously described (p. 123) returned to Ladysmith. A cavalry reconnaissance[112] in the same direction on the 16th found that the commandos had not stirred and, though Olivier's Hoek, Bezuidenhout's, Tintwa and Van Reenen's Passes were all occupied,[113] the country east of them was as clear of the enemy as heretofore. There appeared an unaccountable hesitation amongst the Free Staters. Rumours of disagreement, and even of actual hostilities between the commandos, reached the British camp. They were not altogether groundless, and Sir G. White, utilising the respite, set himself to consider how his field force might be turned into a garrison, and his place of rest into a fortress, should it be necessary, as now seemed likely, to stand a siege in Ladysmith. A complete scheme of defence was drawn up on the 16th, and a mobile column organised for instant service in any quarter. But, whilst the real enemy lay idle on the west, rumour, working in his favour far to the southward, troubled the British general and robbed him of troops he could ill spare. On the 17th a telegram from the Governor of Natal announced that there was evidence of a contemplated Boer raid viâ Zululand upon Pietermaritzburg and Durban,[114] and asked for reinforcements for the defenceless capital. They were promptly sent,[115] and quitted Ladysmith just as the Free Staters in the mountains received with much discussion the order to cross the frontier. Before dawn of the 18th all the commandos were on the move down the defiles, the men of Bethlehem in Olivier's Hoek Pass, of Heilbron in Bezuidenhout's, of Kroonstad in Tintwa, of Winburg in Van Reenen's, of Harrismith in De Beer's, of Vrede in Müller's. By 8 a.m. Acton Homes was in the hands of 3,000 Boers, and shortly after, west of Bester's station, a piquet of the Natal Carbineers was sharply attacked by the Harrismith commando, and forced to retire with loss. The Boers then occupied Bester's station, where they halted for the night. The news of this rapid development caused a great stir in Ladysmith. As early as the 15th Sir George White had decided upon the evacuation of the camp, which lay outside the town, but hitherto no orders had been issued to this effect. All the 18th the work of removing the troops and stores from the camp to the town
