Nice compilation of info, CBR.

As for all horses being so, the answer is, to my reading experience, since I only had to deal with normal horses that pull wagons or plan vanilla horses that I was riding, is that the warhorses were mostly so. They were nearly useless in normal circumstances, they loved to bite and kick and were, speaking in psychological terms, downright neurotic and extremely violent. The loyalty of the horse is not of much importance, the warhorses just wanted to hurt someone and get their share of adrenaline.

Anyone who deals with horses knows how difficult they can be, even if they are normally treated and cared for, and there is always a trace of insanity in their eyes. My father especially told me of one of the horses (well, it was a she, but I forgot the exact English word for a female horse…) they had when he was younger, which found an exquisite pleasure in biting people in the head. There you go and peacefully feed the animals, forget yourself and don't pay attention for a moment and suddenly that beast yawns and has your head between its teeth, my father said, scratching his head absent mindedly while reminiscing. That beast was vile and crazed to the bone.
