1255~1256년 槽島_牙州海島 대상지 비정과 海戰의 影響

Abstract

Mongolian Forces invaded the important Strategic Islands(戰略海島) of Goryo dynasty between the year of 1255 and 1256. On December of 1255, Mongol Army ambushed Jodo(槽島), but they were repelled by Byulchogun(別抄軍) which was formed by the peoples summoned in their own provinces and Ibbomin(入保民). Jodo had been considered that it was not Jido(智島) in Jeollado(全羅道) but Chodo(椒島) in Seohaedo(西海島). The victory of Jodo battle prevented it's isolation from Strategical Islands located in Bukgye(北界). Also, desperate fighting of Jodo Ibbomin forced Mongol Army to abandon it's invasion on Kangdo(江都). On April of 1256, in the Aju island(牙州海島), a battle broke out. Chungjudosoonmunsa(忠州道巡問使) Hanchui(韓就) destroyed Mongol soldiers who were stationed in Aju(牙州). The Island that Hanchui stayed at first, took over the land of Ibhwado(Ippado) which was located in the entry way of Asan bay(牙山灣). At that time, the Island that Hanchui occupied, was estimated as Seonjangdo(仙藏島) which was nearby Aju coast. The results of Aju island battle, Goryo dynasty secured maritime transportation systems and a sea lane of Chungcheong province. Such successes of naval battles in 1255~1256 had an effect on diplomatic war between Mongol Emperor Heonjong(憲宗) and Goryo envoy, Kim Sugang(金守剛). After naval battles with Mongol Army, Mongol Emperor Heonjong accepted the Goryo's suggestion of peace negotiations. The hardcore content of peace negotiations between Mongol Empire and Goryo dynasty, was integrated into withdrawal of Mongol Army and returning to the capital, Gaegyung(開京) of Kangdo Court(江都朝廷). Through temporary peace negotiations with Mongol Empire in 1256, Kangdo Court could maintain resistant tactics against Mongol.
