fell down

Fell down is the past tense of fall down, describing the action of dropping to a lower level, typically to the ground.

It often implies an unintentional or accidental descent: The toddler fell down and scraped her knee.

Unlike simply "fell," which can describe any downward movement, fell down emphasizes the complete descent to a surface, usually with connotations of loss of balance or collapse: The old barn finally fell down after years of neglect.
