What did the declassified documents reveal?

Cold Open. This is a declassified United States State Department memorandum concerning the activities of the Field Research Unit in Formosa, addressed to the American Embassy in Taipei on March thirtieth, nineteen fifty. The document is notable because it reveals internal U.S. assessments of the unit’s interactions with local authorities during the early Cold War period. The source is archived at The Black Vault. Provenance. The memorandum was released to the public through The Black Vault’s digital collection, made available online at archive dot org. The declassification authority is the United States government, and the record is presented in its original Top Secret classification. The release date is listed as the date of upload to the public archive. The Document. The Foreign Service of the United States of America Bureau of Eastern Affairs Address: Official Communications To: American Embassy, Taipei, Taiwan March thirtieth, nineteen fifty Informal My interview with a representative of the Field Research Unit a few days ago, which occurred pursuant to Tokyo’s telegram number two three one to the Department on March ninth and the Department’s telegram number two three one on March sixteenth to Taipei, was satisfactory in every way.

I am of the opinion that this is not necessary in view of our mutual understanding, and it is undesirable in view of the possibility that a few members of the staff may by some unfortunate circumstance be caught here by the Communists. Certain Chinese authorities must be aware of Field Research Unit activities, and it is not wise to link them in any way to this office. The episode has served a worthwhile purpose, in my opinion, by clarifying our mutual functions, concerns and attitudes. I am perfectly content to limit myself to my sphere and if the Field Research Unit does the same there is no ground for conflict. Sincerely yours, Robert C. Strong Charge d’Affaires ad…
