Kwon Yul was not a great longevity.

 In the 32nd year of King Seonjo's reign, when Leejo proposed the addition of Kwon Yul, the officer strongly criticized Kwon Yul. Kwon Yul, the son of Kwon Chul, was originally foolish and timid, so there was nothing to describe his ambition or resourcefulness. However, after winning a monk's boat once in a dishcloth, he suddenly received a lieutenant colonel and was ordained to Dowonsu. While confronting the enemy camp for a long time, he could not defeat the enemy by making even one plan, but he was afraid and always avoided far away even before he showed his enemy." It's not usually a harsh comment, but the criticism doesn't end with this, it leads to the Battle of the Turbulent Sea. The Battle of Cheolcheonliang was one of the most stupid battles of the Japanese Invasion of Korea in 1592, and Won-gyun, who became a commander of the Samdosugun when Yi Sun-shin was impeached and sent to Hanyang. However, Won-gyun shouted "no suppression", but Kwon Yul made Won-gyun go into battle. In other words, the cause of the Battle of Cheolcheonryang lies not with Won-gyun, but with Won-su (Kwon Yul), who ignored Won-gyun's invincible advance. No matter how much the order of mediation was made in the Battle of Jusa Jeong Yu-nyeon (the Battle of Cheolyang), we should have reported immediately the situation where it was difficult to confront the Japanese by checking the timing and considering the strength. And if he had ordered the chief to organize the army and told him not to look lightly at the enemy, he would not have been able to collide arbitrarily, although there were many enemies. However, Kwon Yul did not keep such a plan in mind, but acted rashly without thinking about it, and even formed Won Gyun, a controller, in a hurry. Thus, none of the hard-won injections for six years were left behind, and many of the walks were not preserved, causing the enemy to invade Honam and Hoseo as if they were in uninhabited. Despite his fear and weakness, the court considered it difficult to find a successor to him, so Kwon Yul entrusted him with the heavy duty of military power. At that time, he was unable to correct his past mistakes and encourage him to fight back and defeat the enemy." However, Kwon Yul will be appointed as the best contributor in five years. He won the Battle of Haengju, one of the three major battles of the Japanese Invasion of Korea in 1592, and he used the highly regarded Kwon Yul, but he used the tactic of running away rather than fighting the Japanese. Then, he was defeated in the Battle of Cheolcheonryang, which he tried to fight with great determination. Nevertheless, Kwon Yul is only known today as the hero of the Battle of Haengju.
