Gi Hyo-jeung from Gwangju raised an army in the name of justice to collect “Uigok” and send it to the king during Imjinwaeran. His comrades consisted of former government officials, Saengwons, Jinsas, and Confucian scholars, who selected him as the head of Uigok. With the central command unit in Naju, Gi circulated his manifesto and circular letter, urging each Kun and Hyeon to take on the task of grain selection. When the king requested him to recruit and send additional soldiers while he was in the midst of Uigok activities, Gi promptly responded by initiating the recruitment process. He loaded 3,300 seoks of grain and 460 soldiers onto 24 ships that he had gathered at Yeongsanpo and Beopseongpo. Gi then embarked on a five-month voyage to Uiju, covering over 2,000 ri, and presented the provisions and soldiers to the king. During the journey, some of his ships encountered strong winds and became stranded on rocks, leading to delays in their travel due to the frozen sea. The Uigok and the army, raised in the name of justice, which Gi submitted to the king, made significant contributions in overcoming shortages of provisions and soldiers. Many of the individuals who participated in this project were members of the Seoin group and the Gi Dae-seung lineage. Some went on to be appointed to public service positions, while many others remain unrecorded in history books despite their participation in the project.
