ABSTRACT

As Danghang-fortress was the key position of diplomacy to China after the occupation of Han-river basin during the period of King Jinheung of Shilla, it was the place which must defend staking the national destiny. Whereas, Backje and Gogurye had to block up the point because they bore the burden of Su or Dang’s Dynasty interference when they attacked Shilla. Finally in 642, Backje's King Uija captured approximately the 40 castles and Daeya-fortress. At the same time it attacked the Danghang-fortress with Gogurye. The reason why Danghang-fortress became a target was to obtain the bridehead for attacking the royal road through attacking Daeya-fortress. it also meant that they couldn’t send a envoy to Dang. But Backje hadn’t been enough strong if for attacking Danghang-fortress lonely. So it asked Gogurye to send the troops. As for the request of military support from Backje, Gogurye accepted that because it retaliated against Shilla for the defeat of Nangby-fortress and Chiljung-fortress battle in the past. In oder to attack Danghang-fortress quickly Gogurye and Backje might use the naval forces than the army. There supposed to be intensive battle between Deuckjeck-island and Danghang-fortress. As the result of the battle, Backje and Gogurye failed to gain secure Danghang-fortress because they could not overcome the difference between the rise and fall of the tide and the geographical conditions. Through this battle, Shilla came to know(identified) the reality of Gogurye and Backje’s alliance and Shilla could inform the fact to Dan and it developed their favorable relations with Dang. So they requested Dang to send out the military forces. Even though Danghang-fortress battle had been considered a kind of one-time regional war thus far, in fact, it occurred under Backje’s deliberate plan. Although this battle couldn’t be blocked Danghang-fortress by Backje and Gogurye, this it is significant that the aim of conducting of the battle was to break the diplomatic relations between Shilla and Dang. Also we need to pay attention to the fact that Backje used different tactics when he attacked Shilla compared to the battle in the past.
