Will ye let escape this horde of Foreign Devil enemies who have hurled at us giant crackers that have spit death, now that they are near enough to feel how the Dragon's blood can strike?

William Henry Frost The Wagner Story Book: Firelight Tales of the Great Music Dramas

The young hero seizes the hilt of the sword to draw it from the dragon's body, and as he pulls it out the blood from the wound spurts upon his hand. It burns as if it were the fuel of the creature's fiery breath. As he feels its heat he puts his fingers into his mouth, and the instant that he tastes the blood the most wonderful thing of all happens to him.

In his rage, he flung his great tail about: it twisted round the horse's legs, and the steed in its effort to get free, only became the more entangled, and at length was forced to throw the knight. Quickly he arose, and laying hold of his powerful sword, struck the dragon a stroke that seemed as if it must prove fatal.
