The Monument for the Participation of the US and ROK Marines in the Korean War was built in Bongilcheon-ri, a site that was fiercely contested, to remember the spirit of the US and ROK Marines who fought in the Korean War from 1950 and to always remember their contributions. The ROK Marine Corps was established in 1949 and helped to seek out and capture remaining
communist troops early on. They strongly impressed the South Korean people during the Korean War, which broke out just one year after their inception. The ROKMC triumphed in the Tongyeong Landing Operation, the first conducted by ROK troops on their own, thereby earning them the nickname ‘Invincible Marines’. In addition, their victory in the battle at Dosolsan earned a promotion for all members and a commemorative calligraphy banner saying ‘Invincible Marines’ handwritten by Former President Seungman Lee himself. The ROK Marines also took part in the Incheon Landing, and raised the Korean national flag (Taegeukgi) at the Capitol building after Seoul was retaken, delivering the message of victory and hope to the Korean people. During the Korean War, the US Marines, who fought side by side with the ROK Marines, won accolades by mowing down the enemy in the face of great adversity. They withdrew from the Korean Peninsula on March 14, 1955. The valiant spirit of the many Korean and US Marines who gave their young lives in heroic battles that turned the tide of the war remains the guardian of a free Korea.
