The battle lasted four days and is said to have been wavering one day and the next before the Praxians turned the day.
It is more likely that the Praxians were fresh troops who were late for the battle and that the World Council was actually losing for most of the previous days.
The horse nomads broke and fled and were slaughtered with their backs to the foes.
Either they were encircled and slaughtered or fled and made their escape; they cannot do both. The only people who can be slaughtered with their backs to the foes are foot troops.
The defeated Horse Nomads are described as having fled to Pent
This is improbable since Dara Happa under Khordavu lay between them and Pent.
