Battle of Agincourt, Act IV, scene iv
Scene summary: As the battle rages across the field, Pistol takes a French prisoner. The scene is comic: Pistol, who cannot speak French, tries to communicate with the Frenchman, who cannot speak English. Fortunately, the boy is present. He speaks very good French and is able to translate, though the hotheaded Pistol makes communication difficult. The terrified soldier is convinced that Pistol is a nobleman and a ferocious fighter.
