At any rate, after completing his affairs in London, Upnor had mounted a stallion (he was a horse-fancier, and so this part of the anecdote was never related without many details concerning this horse’s ancestry, which was more distinguished than that of most human beings) and set off a-gallop for Castle Upnor, accompanied by a pair of squires and a string of spare mounts. They had departed from London around dawn and ridden hard all morning along the south bank of the Thames. From place to place, the river road would cross some tributary of the great river, and there would be a bridge or ford that all traffic must use.
