Arthur Conan Doyle,
The Great Boer War — Chapter 18 The Siege and Relief of Kimberley
(1900)
“ So all day they rode, hussars, dragoons, and lancers, over the withered veld, until men and horses drooped with the heat and the exertion. A front of nearly two miles was kept, the regiments moving two abreast in open order; and the sight of this magnificent cloud of horsemen sweeping over the great barren plain was a glorious one. The veld had caught fire upon the right, and a black cloud of smoke with a lurid heart to it covered the flank. The beat of the sun from above and the swelter of dust from below were overpowering. Gun horses fell in the traces and died of pure exhaustion. ”
