Declassified. Today, a declassified C-I-A record concerning U.S. intelligence on China and the Formosa Straits, dated April twenty-second, nineteen-fifty-five. This document offers a window into the state of Chinese Nationalist defense preparations during a period of high tension. It is publicly available via vault.fbi.gov. This report was declassified and released by the Central Intelligence Agency in two-thousand-three under the authority of H-R seventy-dash-two. The document has undergone no change in classification since its initial review. The document is a Current Intelligence Bulletin from the Office of Current Intelligence, Central Intelligence Agency. The subject is "The Formosa Straits: Report of the I-A-C Current Intelligence Group for the Formosa Straits Problem." This report is based on information received in Washington up to eleven-hundred hours, April twenty-first, nineteen-fifty-five. One. The over-all rating of the Chinese Nationalist defense preparations on the Matsu Island Group is "satisfactory." This rating was the result of a series of combat readiness tests completed on April fifteenth by a team from M-A-A-G, Formosa. The series of tests did, however, note some serious weaknesses including the seriously understrength regiment garrisoning the Paichuan, White Dog, Group, twelve miles south of Matsu, the inexperience of the division staff garrisoning the Matsu Group, and the slowness of Ministry of National Defense augmentation of M-A-A-G recommendations for increased weapons. Other inspections of the offshore islands have shown that morale of the regular troops is generally high but the morale of the guerrillas is very low. The situation on Wuchiu, midway between Matsu and Quemoy, which is garrisoned by six-hundred guerrillas, is so bad that M-A-A-G has recommended that it be garrisoned by regulars or abandoned. [four lines redacted under exemption B1] The document includes a map of the Formosa Straits, indicating locations such as Foochow, Quemoy, and the Matsu Island Group, with notations on Nationalist garrisons and airfield construction. One inset map specifically highlights the Matsu area, noting that the Paichuan (White Dog) group, located south of Matsu, has a Nationalist garrison that is understrength, and M-A-A-G recommends abandonment or garrisoning with regulars. The Black Vault’s archive entry for this document notes that it provides valuable insight into the U.S. assessment of the Chinese Nationalist forces in the Formosa Straits during a critical period of Cold War tensions. It underscores the challenges faced by Nationalist forces and the recommendations made by U.S. advisors. This is what the public record looks like at its most ordinary.
