How Did Annabel Lee Die in the Poem?

In Edgar Allan Poe’s poem ‘Annabel Lee,’ the cause of Annabel Lee’s death is attributed to a chilling wind that blew out of a cloud. The poem suggests that this wind was responsible for making her ill, which ultimately led to her death. The narrator describes how the wind came ‘chilling and killing my Annabel Lee.’ This implies that the wind was so cold and harsh that it caused her to fall sick and die. The poem does not provide a detailed medical explanation but uses this imagery to convey the tragic and untimely death of Annabel Lee.
