Declassified brings you a Central Intelligence Agency record from September nineteen-fifty-eight, providing a daily brief on the Communist Bloc, with a focus on the Taiwan Strait situation.

This record, identified as number CI01319, was released to the public under the Freedom of Information Act and is available via The Black Vault and the Internet Archive.

Increasingly concerned over failures to resupply the Kinmens, the Chinese Nationalists will put heavy pressure on the US to assure supply of the island." "Available evidence fails to reveal that the USSR has taken any measures, precautionary or otherwise, which might reflect preparation for an early implementation of Soviet commitments to the defense of [two lines redacted under exemption B1]."
