The Abbess of Vlaye by Stanley J. Weyman

The horse looked piteously at the man. Blood oozed from its broken knees and its legs quivered under it. The man holding his scratched and abraded hand to his mouth returned the beast's look, at first with promise of punishment, but by and by less unkindly. He was a just man, and he saw that the fault was his; since it was he who, after crossing the ridge, had urged the horse out of the path that he might be spared some part of the weary descent. Out of the path, and cunningly hidden by a tuft of rough grass, a rabbit-hole had lain in wait.

He contented himself with a word of disgust, therefore, chucked the rein impatiently -- since justice has its limits -- and began to lead the horse down the descent, which a short sward rendered slippery. But he had not gone many paces before he halted. The horse's painful limp and the sweat that broke out on its shoulders indicated that two broken knees were not the worst of the damage. The man let the rein go, resigned himself to the position, and, shrugging his shoulders, scanned the scene before him.
