Meanwhile, on 13 May, General Harrison, senior UN representative at Panmunjom, made a counterproposal to the Communist plan. This incorporated three measures aimed at reconciling differences in the long-controversial repatriation issue.[402] Arguments flew back and forth at Panmunjom, with a temporary recess called in the talks; but on 4 June the Communists accepted this UN final offer. The dispute of 18 months’ duration had ended and the Allied principle of voluntary repatriation had won out in the end. About the only homework left for the negotiating teams was to map out final details of the Demilitarized Zone. [402] In brief, these were: (1) that the Neutral Nations Repatriation Commission (NNRC) take custody of Chinese nonrepatriates but give Korean POWs the option of settling either in North or South Korea, as they wished; (2) that troops from just one country (India) be used to guard nonrepatriates, rather than the unwieldy five-nation force earlier proposed by the Communists; and (3), that specific procedures, which were clearly spelled out, be followed for granting political asylum to returning prisoners who refused repatriation. President Rhee now even more violently denounced the projected armistice plan. He declared that he and the Koreans would fight on alone, if necessary. South Korean delegates boycotted the Panmunjom truce meetings, and Rhee began a campaign to block the cease-fire. Final agreement on the POW issue was reached 8 June. It provided that the NNRC offer a “civilian status” to former POWs who did not exercise their right of repatriation within four months after being taken into custody by the commission. Those POWs who desired asylum would be set free. The South Korean National Assembly unanimously rejected the truce terms the following day. Revision of the truce line, to correspond to current battle positions, and other concluding details of the truce were being settled by 17 June. On 18 June, chaos suddenly replaced progress. Acting on orders from Rhee, during early morning hours ROK guards at the South Korean prisons released approximately 27,000 North Korean anti-Communist POW inmates (the majority of the large group of NKPA who did not wish to be repatriated). They quickly escaped and became absorbed into the civilian populace of South Korea. Immediately the Communists charged the Americans with complicity and demanded to know whether the United Nations Command was able to control its South Korean ally or not.
