palace, called his servant and said to him: "Listen, my dear! Go out to the city walls, drive away the foreign troops, and for this service I will return to you your note, by which you denied your kingdom and swore to be my servant." The honest Prince Kindhearted put on his knightly armor, mounted his steed, went out to the city walls and called in a loud voice: "Knight Invisible!
