Before we begin relating the events with which this book is actually concerned, and which took place, as we have said in the previous chapter, exclusively in and around the capital, I must ask my reader to turn his attention for a few moments to that great mining centre, Johannesburg, "The Golden City" of South Africa. If it was hated by the Boers before the war as the cause of all the unrest in their beloved country, the unwelcome revolution in the calm simplicity of their hitherto peaceful life, it is not to be wondered at that their hatred and resentment had been intensified by the way in which the war was brought about. This feeling had risen to its height of concentrated fury when it became known to the burghers that the sweeping advance of the British forces in overwhelming numbers would soon make it possible for the English to take full possession of those coveted mines. At the time of the Republican successes there had been no suggestion that it would be politic to destroy the mines, but as reverses became more frequent, and it became evident beyond a doubt that the British troops were about to cross the Vaal, a strong section of the Government, supported by popular feeling, openly advocated the destruction of the mines as well as the town of Johannesburg. The precedent quoted for such a course was the burning of Moscow by the Russians, in order to retard the victorious advance of Napoleon. Very soon it became apparent that the members of the Government who were advocating this policy were gaining the upper hand, as instructions were actually given to certain officials of the Mines Department to make the necessary arrangements for blowing up the mines. Another section of the Government, among whom were General Louis Botha and Dr. F.E.T. Krause, strenuously opposed the carrying out of this policy. This section eventually gained the upper hand at the time when Commandant Schutte was compelled to relinquish the position of Special Commandant for the Rand, and Dr. Krause was appointed in his stead, although the circumstances leading to this change had at first in some measure strengthened those who advocated destroying the mines. The change was brought about in consequence of the terrible explosion at Begbie's Engineering Works, which had been converted into a bomb factory by the Government, and where several persons were killed and many injured. The cause of this explosion after investigation was alleged to have been the work of British spies, and it was only natural that those persons advocating the destruction of the mines should avail themselves of this circumstance to further their scheme, but the bold and determined opposition of Dr. Krause, supported as he was by the mines police, a special body of men organised for the purpose of protecting the mines, had the effect of inducing the "Destroyers" to mature their scheme in secret.
