In the year 1380, Agibaldo appeared at the mouth of Geom river on the Korean Peninsula, with 500 ships. They met with Lee sung-gye’s troops and fought them. This battle is referred to as the Battle of Hwangsan. In my thesis, I asserted that the identity of the Waegoo lay with the people living in coastal areas in Takagi of Nagasaki-ken and Amakusa of Kumamoto-ken, under the influence of the Southern Dynasties of the Period of the North and South Dynasties. As an extension of this argument, I studied the Battle of Hwangsan militarily and historical-geographically. The tactic employed by Agibaldo at the Battle of Hwangsan was the “Jowoon jin”, which derived from the ancient Chinese military code book, 六韜. The Kikuchi clan had their own defensive tactics-the “Doho jin”. The latter was very similar to “Jowoon jin”, and was unique to other armed forces during the Northern and Southern Dynasties. The tactics of Doho jin and Jowoon jin utilized at the Battle of Hwangsan were very similar in terrms of the terrain conditions of the camp, place of operation, time of the battle, and method of attack used against the enemy. Furthermore, the area around Waihu Castle, the home of the Kikuchi clan, also had a geographical location which was deemed perfect according to the Doho jin tactic.
