A week after the division’s June replacements landed at Inchon, General Selden’s headquarters received a directive that would affect a number of these new Marines. On 10 June CG, EUSAK ordered his corps commanders to make continuous efforts to secure the identification and changes in the enemy order of battle. Two days later I Corps followed the Eighth Army order with a letter of instruction which called for each I Corps division to “prepare plans for launching swift, vigorous, and violent large-scale raids to capture prisoners, to gain intelligence, to destroy enemy positions and material and/or strong limited objective attacks to improve and strengthen Line JAMESTOWN.”[136] Large scale was defined as an “attacking force limited to battalion or regimental (brigade) size with appropriate armor and artillery support.”[137] Divisions were required to submit detailed proposals for future action by 21 June. Marine division plans for limited objective attacks during July by units of the 7th Marines and KMCs were subsequently prepared and forwarded to I Corps. [136] 1stMarDiv ComdD, Jun 52, App. I, p. 8. [137] _Ibid._ One operation conducted north of the 2/5 left battalion sector early on 22 June was not, however, in response to this enemy identification mission. Late the previous day, Company G had sent out a 16-man ambush. Before the Marines reached their destination, a small enemy force, itself lying in wait, began to pour a heavy volume of fire on the Marines. At this point the patrol was ordered to pull back. One group of 10 made it back to the MLR; the remaining Marines headed for a nearby combat outpost in friendly hands. Reports to the company revealed one Marine not accounted for. The outpost commander was directed to search the area for the missing Marine. This reconnaissance by a fire team failed, but a reinforced squad sent out later brought back the body of the Marine who had been killed by Chinese artillery.
