Around the age 11 or 12 Araminta had a serious head injury that could have killed her. Araminta was sent to a dry-goods store for supplies. There, she encountered a slave owned by another family, who had left the fields without permission. His overseer, furious, demanded that Tubman help restrain the young man. She refused, and as the slave ran away, the overseer threw a two-pound weight at him. He struck Araminta instead,Tubman endured seizures, severe headaches and narcoleptic episodes.
