…And there she lulled me asleep, And there I dreamed—Ah! woe betide!—
The latest dream I ever dreamt
On the cold hill side.
I saw pale kings and princes too, Pale warriors, death-pale were they all;
They cried—'La Belle Dame sans Merci
Thee hath in thrall!'
I saw their starved lips in the gloam, With horrid warning gaped wide, And I awoke and found me here,
On the cold hill's side…
