What did the declassified documents reveal?

Declassified. Today we examine a declassified intelligence memorandum from the Central Intelligence Agency, dated September ninth, nineteen-fifty, concerning Chinese Communist participation in the Korean War. This document is available at vault.fbi.gov and documents2.theblackvault.com. This document was declassified and released to the public under the Freedom of Information Act. While a specific F-O-I-A case number is not listed, its declassification was authorized as part of a broader release of C-I-A records related to the Korean War. This memorandum is part of a larger collection of United States intelligence on China. The document reads: Subject: Chinese Communist participation in Korean War forces in China. Reference: The Chief of Staff's request for evaluation of paragraph four of attached memorandum, dated two September nineteen-fifty. Number one. To the best of anything from Chinese Communist sources, troops with a good part of the Korean contingent of the Fourth Field Army have been transferred from South China to Manchuria during the early phase of this year as reported in Intell C-O-Y two three six seven four. The majority of the estimated one hundred forty thousand Koreans in the Korean Volunteer Army, which was disbanded during nineteen forty-seven, were integrated into the F-L-A troops, and many of them remained with the Fourth Field Army during the past year. Approximately twenty-five thousand Japanese troops are still in South China, serving in artillery and other units in various technical capacities. It is probable that the numerous reports of large-scale movements of Chinese Communist forces northward from Canton during the spring and early summer of this year were actually Korean, Manchurian, and Japanese troops being transferred to Manchuria and Korea. The presence of large numbers of Chinese Communist-trained Koreans in combat areas has been confirmed through interrogations. For example, six out of five hundred interrogated prisoners formerly served with the Chinese Communist Fourth Field Army. Although, to date, no Japanese have been taken prisoner, a R-O-K army officer fighting in Yongdok reported that he had observed Japanese in the E-P-A army and heard troops speaking Japanese. Many Koreans do speak Japanese. His statement has been confirmed by other prisoners of war. The present strength of Chinese Communist forces in Manchuria is estimated at two hundred forty-five thousand. At least one hundred sixty thousand of these troops are reportedly along the Manchurian-Korean border. Rather than enter the war as active participants, it is probable that the Chinese Communists, if called upon to do so, would furnish replacements for direct integration into Korean units. This document represents a small but significant piece of the United States intelligence record during a critical period of the Korean War. This is what the public record looks like at its most ordinary. For this document and more, visit storyflo.com and the…
