Courage is a form of loyalty; a knight trusts another courageous knight
Plinio Corrêa de Oliveira
Edward, the Black Prince, accepts the surrender of John II of France at the Battle of Poitiers.
Naturally, you need to have a keen eye to be able to do this! Not just anyone can do it. But in general, a courageous knight trusts in the character of another courageous knight; because courage is a form of loyalty. And one who is very courageous—not courageous like a bandit, but like a hero—does not know how to lie. So the other knight trusts him.
And later the winner sends good clothes, good food rations and a special tent to the great man he defeated. This is gentlemanly. But here there is no rivalry; on the contrary, the winner glorifies the one he defeated. This is beautiful.
