The king is sending the herald off with an earful, it seems, even if Percy can't catch all of it. He might catch the herald's parting words: "Fare thee well: thou never shalt hear herald any more." But he's already forgotten by the leaders of the English army: a confirmation of York's place in the vanguard; and how thou pleasest, God, dispose the day!

They'll be in motion soon, Hotspur. All the battle you could want.
