The Kim Seongeun Unit of the ROK Marine Corps, which defeated an enemy battalion in the Hamyang and Jinju battles, launched a surprise attack on North Korea’s 6th Battalion’s Reconnaissance Unit and decimated them in Jindong-ri, west of Gosa-ri on August 3, 1950. This was the greatest feat since the establishment of ROKA, earning all unit members a promotion. The ROK Marine Corps, which earned a reputation of ‘invincibility’ in the Tongyeong Landing, again made a decisive contribution to defending the Busan Perimeter. The KEAN Task Force, which part of key soldiers of the US 25th Division, waged a major counterattack in the direction of Jinjugogae between August 7 and 13. Meanwhile, ROK Marines shut off the enemy supply line between Jindong-ri and Masan, and completely drove the enemy out of Yabansan, Suribong and Seobuksan. They then detoured to Haman and Gunbuk, destroying the enemy at Pilbong, Obongsan. Thus, they defended the Jindong-ri region with uncommon valor, helped the ROK Marines neutralize the desperate attack by the North Korean 6th Division, defended the strategic points of Masan and Jinhae, and helped bolster the Busan Perimeter. The ROK Marine Corps Command built a monument of victory there, where the fighting was the most intense, to remember for all time the South Korean and United Nation soldiers who gave their lives defending South Korea and to commemorate their victories there.
