What did the declassified documents reveal?

Declassified. Today, we examine a declassified Army intelligence summary from July fourteen, nineteen-fifty, concerning intelligence on Korea and North China. This document offers an early U.S. assessment of Chinese Communist and Soviet involvement in the Korean peninsula at the outset of the Korean War. This record is publicly available from The Black Vault, at archive.org/download/us-china-intel-CI00386/CI00386djvu.txt. This document was approved for release on December sixteenth, two-thousand-nine. Its declassification authority is not specified on the document itself. The original classification was Top Secret, with a caveat of "COPS", indicating Controlled Official Production System. It was released in response to a Freedom of Information Act request.

Reinforcements for the North Korean Army may be drawn from the estimated seventy thousand Korean troops of the Chinese Communist Army who are believed to be located at present in Manchuria. Soviet advisers are known to be located in key areas of North Korea (estimated five thousand) and Communist China (estimated five thousand for ground forces alone). Top Secret – COPS.
