This document offers insight into the early stages of U.S. intelligence analysis regarding Chinese Communist intervention in the Korean War. You can find this document on archive.org, linked from theblackvault.com. This document was released to the public under the Freedom of Information Act and declassified by authority of an Army Chief of Staff for Intelligence letter dated March twenty-fourth, nineteen-fifty-nine.

The Air Attaché, Taipei, forwards a report allegedly transmitted by Father Wang, an active anti-Communist in North China, according to the document, to a friend in Hong Kong through a Father Li. Father Wang reportedly obtained the information from a religious friend who is employed in the Administration Council in Peking. This friend came into possession of a document in connection with his duties. When he noticed its extreme importance, he supposedly memorized the contents and later reproduced them for Father Wang.
