Gungye, who recorded remarkable performance as a follower of Yanggil, a powerful clan based on Wonju, Gangwon Province, advanced into Gangreung and then became himself a general. At the same time, he started to win influential men around the region rapidly. A critical point for this is Binoi castle battle. Even many suggestions, it has been verified that the location of the castle was Jukju mountain fortress. Yanggil, at that time, was a head of the powerful clans group while commanding around 30 neighboring castles including Gukwon castle. But from his miserable defeat at the Binoi castle (not only strategic spot but traffic junction) battle, the middle area of the Korean Peninsula got under the influence of Gungye. Right after the Binoi battle, Wanggeon and Jinhwon, followers of Gungye, fought a fierce battle at Munmak, Wonju. This battle is not recorded in history books, but it could not be simply neglected because there are many legends, stories and relevant relics about this battle. In particular, Songwajapseol , an anthology of the end of the 16thcentury, contains this battle. Considering interest in the Hangang waterways’regions and the inner land of the Korean Peninsula, Jinhwon could not ignore the collapse of Yanggil and rising Gungye. In that sense, we could understand the Munmak battle as a battle caused by Jinhwon’s intervention. With the overwhelming victory of the Binoi castle battle, Gungye could firmly lay the foundation for a nation foundation. That is, the fact that the three castles of Chungju (Gukwoncastle), Wonju (Pyeongwon castle) and Yangju (Southern Pyeongwon castle) were separated capitals (meaning sub capitals: Refer to the writer!!) of Goguryeo was a help to him. Then, Gungye was confident that he could take over the old city of Pyeongyang and become a successor to Goguryeo, which meant also that he had hegemony for the situation,and furthermore, he sought to integrate the Samhan by Goguryeo. From this, Wonju has a meaning as ‘the starting point that brought the future foundation of Goryeo.’
