Ŏ Yŏngdam was born in 1532. His hometown is unknown, but he is said to have lived in Haman County, Gyeongsang Province. He excelled in martial arts and resourcefulness and was specially recruited as a subarea commander of Yeodo at an early age. In 1564, he passed a military examination as a third person among third-tier passers.He started his career on 1 December 1580, as a magistrate of Sacheon. Later, he was assigned as a magistrate in Goryeong, Mujang, and Eonyang, focusing on the coasts of Gyeongsang province and Jeolla province. He examined sea routes in detail, allowing the entry and exit of ships. In May 1592, he led Yi Sun-sin's waterway as a magistrate of Gwangyang. From the Battle of Okpo to the Battle of Angolpo, as the Central Commandant, he played a big role in victory by defeating a total of 8 ships. In recognition of this contribution, he was promoted to Tongjeong, the third senior rank. When preparing for the provisions, He stored separately seeds of crops and crops for people's first aid. In February 1593, while he was participating in the Battle of Ungcheon and thus was not in Gwangyang, Im Bal-yeong, the secret royal inspector of transportation, misunderstood the food stored separately and asked for his dismissal. Yi Sun-sin and the people of Gwangyang launched a campaign to publicize his innocence but were eventually dismissed. Later, Yi Sun-sin raised his ambition to appoint him as an Assistant Defense Commandant again and received permission from the court. In the Second Battle of Danghangpo, he smashed two large ships as the Assistant Defense Commandant.
On April 9, 1594, he died of an infectious disease in Hansando.
