I am in the middle of a novel set in Britain during the Roman invasion. It is the second book in a series and, until very recently, has been pretty spot on with all the horse-stuff…which is actually the only reason I am asking this question. Pretty sure I know the answer, but I know I don’t know everything so…
In a conversation between two Roman cavalry officers who were comparing the types of horses their units kept, one said that the Gaulish cavalry liked to have mares because “they can urinate at a full gallop in battle”.
Every single mare I have ever known–including the two I own–makes a huge production out of peeing. Has anyone ever encountered a mare that could/would do it while moving at all–let alone at a gallop? The books seem to be pretty meticulously researched and, like, I said, up until this nugget, were pretty accurate with horse stuff.
