Yu-sin

Pattern is named after General  Kim Yu-Sin, a great commander of the Silla Dynasty, who was instrumental in uniting the three kingdoms of Korea. Yu-Sin felt that Paekche, Koguryo, and Silla should not be separate countries, but should be united because all the people had the same ethnic background. He is regarded as the driving force in the unification of the Korean peninsula and is the most famous of all the generals in the unification wars. 

Yu-Sin became a Hwarang at the age of 15 and was an accomplished swordsman and a Kuk-Son by the time he was 18 years old. By the age of 34, he had been given command of the Silla armed forces. Yu-Sin was active on all fronts in the wars and many times he simultaneously conducted battles against both Paekche and Koguryo. He defeated the great Paekche general Gae-Baek in the battle in which Gae-Baek was killed.
