But so tame and inglorious a policy is impossible to a fighting soldier. He could not with his splendid force permit himself to be shut in without an action. What policy demands honour may forbid. On October 27th there were already Boers and rumours of Boers on every side of him. Joubert with his main body was moving across from Dundee. The Freestaters were to the north and west. Their combined numbers were uncertain, but at least it was already proved that they were far more numerous and also more formidable than had been anticipated. We had had a taste of their artillery also, and the pleasant delusion that it would be a mere useless encumbrance to a Boer force had vanished for ever. It was a grave thing to leave the town in order to give battle, for the mobile enemy might swing round and seize it behind us. Nevertheless White determined to make the venture. On the 29th the enemy were visibly converging upon the town. From a high hill within rifleshot of the houses a watcher could see no fewer than six Boer camps to the east and north. French, with his cavalry, pushed out feelers, and coasted along the edge of the advancing host. His report warned White that if he would strike before all the scattered bands were united he must do so at once. The wounded were sent down to Pietermaritzburg, and it would bear explanation why the non-combatants did not accompany them. On the evening of the same day Joubert in person was said to be only six miles off, and a party of his men cut the water supply of the town. The Klip, however, a fair-sized river, runs through Ladysmith, so that there was no danger of thirst. The British had inflated and sent up a balloon, to the amazement of the back-veld Boers; its report confirmed the fact that the enemy was in force in front of and around them. On the night of the 29th General White detached two of his best regiments, the Irish Fusiliers and the Gloucesters, with No. 10 Mountain Battery, to advance under cover of the darkness and to seize and hold a long ridge called Nicholson's Nek, which lay about six miles to the north of Ladysmith. Having determined to give battle on the next day, his object was to protect his left wing against those Freestaters who were still moving from the north and west, and also to keep a pass open by which his cavalry might pursue the Boer fugitives in case of a British victory. This small detached column numbered about a thousand men--whose fate will be afterwards narrated. At five o'clock on the morning of the 30th the Boers, who had already developed a perfect genius for hauling heavy cannon up the most difficult heights, opened fire from one of the hills which lie to the north of the town. Before the shot was fired, the forces of the British had already streamed out of Ladysmith to test the strength of the invaders.
