His tactics are flawed and that's why he lost and died.
The king should never move first but stay behind, preferably on horseback and on a hill to overlook the battle and give out orders. His flagrantism and melodramatic battle actions cost him the victory.
He planned to lose and to die.
Your move, OP.
See, you're using realistic tactics.
This is more like the glorified romantic image of tactics found in medieval romance texts.
It's fitting that way.
