War on English soil ensues with the Bastard actually leading the army and acting as the King, since King John falls ill and seems incapable of making decisions. The Bastard's army wins the day's battles. A dying Frenchman, Melun, warns the English Lords that Lewis plans on beheading them as soon as the battle with the English is over, so the Lords switch back to King John's side. Resting at a monastery, a monk poisons King John, though the monk himself dies after tasting the food for King John. Pandulph convinces the French to make peace and return to France, and Prince Henry is named the new king.
Time period is approx.
1210-1216 A.D. Also, King John signed the Magna Carta, though Shakespeare makes no mention of this.
