Which phrase or sentence from the story offers the best visual description of people's reaction to the horse?

I was at Count Przobossky's noble country seat in Lithuania, and I remained with the ladies at tea in the drawing room, while the gentlemen were down in the yard to see a young, pedigreed horse that has just arrived. We suddenly heard a noise of distress. I hastened downstairs and found the horse so unruly that nobody dared approach or mount him. The most determined horsemen stood dismayed and aghast; hopelessness was expressed in every face.
