The knights of the Vale weren’t intended to be a focal point; after the Battle of the Bastards I believe we’re just supposed to assume their presence because they are the main body of Sansa’s military strength/support.
^Yohn Royce is not a person who would run away from battle..
He wasn't Yohn Royce..That guy is a war veteran and a staunch loyalist, check his history out..I don't believe he ran..
I don’t think he and his army were there. Hopefully they still have the knights of the vale
They were there when Jamie got interrogated. They didn't leave that quickly
