The brief respite ended 24 June when the CCF again directed heavy blows against the ROK troops, ignoring other UN forces in the Eighth Army line. It was generally considered a retaliatory move for the 18 June mass release of anti-Communist prisoners by South Korean President Rhee. This time the major target of the renewed Chinese offensive was the ROK 9th Division, in the IX Corps sector immediately west of the ROK II Corps. On 25 June the 1st ROK Division on the eastern flank of I Corps, to the right of the 1st Commonwealth Division, was pounded by another Chinese division. Significantly, the date was the third anniversary of the invasion of South Korea.[436] The 7th Marines, training in I Corps reserve, was put on standby status. The regiment was removed the following day when the 1st KMC/RCT (minus its 3d Battalion) was instead placed in readiness,[437] and subsequently moved out from its Indianhead area to be committed as a relief force in the left sector of the 1st ROK line. [436] The strong likelihood of such attacks at this time had been noted by Eighth Army in a warning issued the previous day that reminded all commanders to be “particularly alert” at this time.

[437] This change was due to the existing policy of not having a United States unit serving under operational control of a Korean commander. Had the 7th Marines or other U.S. unit been so committed, it is expected that a provisional task force would have been created for the assignment, under a non-Korean commander. _PacFlt EvalRpt_ No. 6, Chap. 9, p. 9-20. Actually, the 7th Marines alert on the 25th was of such short duration that no mention of it appears in the regimental command diary, although the fact is so noted in division records. The 1st KMC/RCT was ordered to move out from the Indianhead area at 1630 on 26 June and came under operational control of 1st ROK Division at 1540, 27 June. By 0100 the following day, it had relieved 11th ROK Regiment. _ROKMC Comments._
