Instantly all was flurry and confusion. Men that a moment before had been sleepily yawning after their heavy labours were racing hither and thither, groping in the darkness in search of arms. Others however, who were armed, forebore to fire, the felt hats of the foe being mistaken for those of the Imperial Light Horsemen. With a desperate effort Lieutenant Digby Jones gathered together his sappers. Hurried shots were fired, hurried orders given, but nothing could efface the effects of the sudden surprise. The Boers had gained the hill and driven the defenders over the crest! This all in a darkness that might have been felt. Such lanterns as there were had been overturned and extinguished in the hustle of the stampeding Kaffirs, who had been assisting at the arrangement of the gun, and who, at the first approach of the enemy, had fled. Forks and flashes of flame shining from the nek between the twin hills showed that the second column of the Dutch commando also was attaining its object. The gun, which fortunately had not yet been erected on the top of the hill, was instantly got to work under the direction of Lieutenant Parker; rifles were seized, and an effort was made in the obscurity to sweep the hill in the direction where the enemy was supposed to be. But the Boers were completely enveloped in the darkness of the night, and it was impossible to locate them; and the Hotchkiss gun was drawn back within the sandguard which had hurriedly been thrown up, only just in time. The Boers were now almost upon it. All the available men about Wagon Hill had instantly rushed to the rescue, and the Imperial Light Horse, some King's Royal Rifles, and a few Gordon Highlanders were soon in the thick of the fray. The Highlanders, taking their place round the crest, fired, as hard as rifles would let them, down the slope. Some fierce fighting followed. Before the Boers could get farther up, the Imperial Light Horse with their wonted gallantry engaged them, and sent the invaders helter-skelter down hill into the mysterious mists of the dawn. But this was but for a moment--it was merely the commencement of affairs.
