Operation Bluehearts

Operation Bluehearts was code name for the original plan for an amphibious landing behind enemy lines during the Korean War.
More specifically, the plan was to land an assault force from the 1st [Cavalry Division (United States)|1st Cavalry Division] and the Marine Corps|Marine] Regimental [combat team|RCT] against the Korean [People's Army|North Korean Army]'s rear at Incheon as early as 22 July.

Thereafter, 1st Cavalry Division landed at Pohang on 18 July 1950.
