For four days, Catherine thought she was going to die.
In 1993, 18-year-old Catherine Conteh was in labor at a hospital in Freetown, Sierra Leone.
Her baby was stuck. Doctors said she needed an emergency Caesarean section, but Catherine and her husband, Augustine, couldn't afford the surgery.
Without payment, there would be no operation.
Then a New Zealand nurse named Aly Hall heard Catherine crying.
Aly was volunteering with Mercy Ships and visiting the maternity ward. She went to Catherine's bedside, prayed with her, and learned that roughly $100 could save both mother and baby.
Aly's fellow volunteer, British anesthetist Dr. Keith Thomson, heard what was happening and offered to pay for the surgery himself.
The operation went ahead.
Catherine survived. So did her daughter, Regina.
Thirty years later, Catherine and Aly reunited in Freetown. By then, Catherine had become a nurse. So had Regina.
Looking back, Catherine said that one decision had saved an entire family.
