초록

This study investigates Jeong Ji who served as a military leader in the fourteenth century, the historical period marked by frequent invasions of Japanese invaders. Jeong Ji held various positions, including Navy Marshal, and spent most of his career in repulsing Japanese invaders. JeongJi is an individual who is not well known to the public, research is also lacking compared to other figures.
While playing a key role in repulse Japanese invaders alongwith Choe Young and Lee Sunggye, Jeong Ji insisted on the use of new tactics that are different from existing strategies such as combat by force and land warfare. His new tactics to deal with Japanese invaders are described in his letter of opinion submitted in the 23rd year of King Kongmin, which now serve as a valuable historical writing. Unlike the land warfare where Choe Young and Lee Sunggye succeeded the battlefields, the hegemony of the navy warfare was overtaken by Japanese invaders after a series of Goryeo's losses. Prior to Jeong Ji's letter, Choe Young, Woo Hyeonbo, and Lee Hee had submitted other letters of opinion to resolve the problem but in vain.
Jeong Ji's letter submitted in the 23rd year of King Kongmin outline the problems of the Goryeo Dynasty's navy as follows: Byeongmasa(a local military official in the Goryeo Dynasty) appointed military leaders who have no professional experience as commanders of the navy; the navy commanders had no experience in the navy warfare; and corrupted officials had been appointed as commanders. The major suggestion of Jeong Ji's anti-Japanese invaders strategies was to build a navy through specialized training. Such strategy was essential to take the upper hand in the navy warfare against Japanese invaders. Once the navy's competitiveness is secured, another crucial tactic was to construct warships.
As the Battle of Jinpo became a new turning point for withdrawing raiders, the Battle of Gwaneumpo led to lessening invasions of Japanese raiders. Even with the achievements made from the battles, it could not stop raiders from invading. To eradicate the invasions once and for all, JeongJi filed an appeal to punish Daemado.
To resolve the conflicts of invading raiders and of involving diplomatic relations with Japan and China, JeongJi filed an appeal to punish Daemado and Iki Island where the raiders were based. Unfortunately, the appeal was turned down due to the turbulent political party. It was until the first year of King Chang’s reign where Park Wui of Gyeongsangdo Dowonsu(provincial military leader) led the conquest of Daemado.
Immediately after the founding of the Joseon Dynasty(朝鮮), the King acknowledged Jeong Ji's contributions to defeating Japanese invaders by building warships and conferred benefits to his descendants, as a sign of the Dynasty's recognition of the effectiveness of his anti-Japanese invaders strategies.
Although he died at the young age of 45, he was a warrior who had a great influence on the naval forces when the nation was at crisis from Japanese invasion during the late Goryeo Dynasty. He valued the role of naval forces and sought to eradicate Japanese pirates by accurately grasping the international situation.
