It was about a young girl who lived in the Hartz Mountains, and who had given up her life to save her lover's soul; and he died, and met her spirit in the air; and then, in the last verse, he jilted her spirit, and went on with another spirit - I'm not quite sure of the details, but it was something very sad, I know.
Elle parlait d’une jeune fille vivant dans les montagnes du Hartz, et qui avait donné sa vie pour sauver l’âme de son fiancé. A sa mort, celui-ci retrouvait l’âme soeur dans l’au-dela, mais, au dernier couplet, il la quittait pour convoler avec un autre esprit.
