British Cavalry Second Boer War

The real irony for the British cavalry in South Africa was that it could have provided a real theatre of war for the demonstration of a well-trained mounted force. The great expanses of open terrain were ideally suited to wide sweeping raids in which the Boer could have been fought on his own terms from the very start. Not only this, but also the Boer battlefield tactics of digging themselves in and awaiting a frontal assault could have led to their undoing. Here was the chance to use the British cavalry to full effect. A mobile mounted force, together with a light and modern horse artillery could not only have turned the Boers out of every position they occupied but also, given enough strength, could have surrounded them completely and cut them off from any retreat to yet another defensive position.
