Kim Yushin - Military Accomplishments

Military Accomplishments

Kim's first military engagement in command is believed to have occurred around 629 AD, and through it he quickly proved his capabilities as a warrior. Silla was in a constant struggle with its neighbor to the west, Baekje, over territory. There had been gains and losses on both sides, and the struggle lasted for many years. It was during this period that Kim rose through the ranks of the military, rising to the position of general and becoming a skilled field commander.

Baekje and Silla had formed an alliance to counter Goguryeo's power and its intentions to push southwards, and together they launched a successful attack on it, Silla taking the northern territory and Baekje the one south of the Han river. But Silla broke the alliance and attacked Baekje in order to claim both territories for itself. After this betrayal, Baekje allied with Goguryeo. When Goguryeo and Baekje attacked Silla in 655, Silla joined forces with Tang Dynasty China to battle the invaders. Although it is not clear when Kim first became a general, he was certainly commanding the Silla forces by this time. Eventually, with the help of the Silla navy and some 13,000 Tang forces, Kim attacked the Baekje capital, Sabi, in 660, in one of the most famous battles of that century, the Battle of Hwangsanbeol.

The Baekje defenders were commanded by none other than General Gyebaek, although the Baekje forces consisted of about 5,000 men and were no match for Kim's warriors, which numbered about ten times as many. Baekje, which had already been experiencing internal political problems, crumbled. Kim's Silla forces and their Tang allies now moved on Goguryeo from two directions, and in 661 they attacked the seemingly impregnable Goguryeo kingdom, but were repelled. The attack had weakened Goguryeo, though. In 667 another offensive was launched which, in 668, finally destroyed Goguryeo.

Silla still had to subdue various pockets of resistance, but their efforts were then focused on ensuring that their Tang allies did not overstay their welcome on the peninsula. After some difficult conflicts, Silla eventually forced out the Tang troops and united the peninsula under their rule.
