The final fight (Spoilers)
So somehow King Robert and King Edward II are going at it, man to man.
The entire rest of the English army has run away.
Edward is literally surrounded by Scottish soldiers.
WHY NOT TAKE HIM CAPTIVE????????????????????
A) Why allow him to fight and possibly kill Robert?
B) Why not take him for ransom. The English would be forced to pay tons of gold for him.
C) Most importantly ... why not use him as leverage to ensure Scottish independence? The battle was won, but there was no indication that the war was over.
I know this scene is fiction, but it was really stupidly written.
