Read the full text of King John Act 5 Scene 5 with a side-by-side translation HERE.
Louis the Dauphin is alone on stage.
Louis says that the sun has just set, and the English are hightailing it off the battlefield. Looks like things are going okay for the French.
A messenger runs in and is all, "OMG, Count Melun is totally dead! Plus, all your English allies have betrayed you, and a bunch of our ships just sank!"
Louis takes the news pretty well, all things considered. He swears to get up early the next morning to see what the day will bring him.
