UNIT 731

1. Public Record

Unit 731. Pingfang, outside Harbin. Ishii Shiro. Human work dressed as water purification. Vivisection, frost, plague, anthrax. Prisoners called logs. The plant was demolished as the Soviets came. Ishii lived. In 1947 Camp Detrick sent men, among them Norbert Fell, Edwin Hill, Joseph Victor. They sat with Ishii and more than twenty others. Ishii asked what they wanted to know. A May 1947 MacArthur channel discussed keeping the product in intelligence files, not in a war-crimes docket. SWNCC language that August: this was the only known controlled human data of its kind, and a trial would put it in the street.

No single signed immunity ribbon has been produced. The practical bargain is the file: data to Detrick, no dock at Tokyo for the principals. The Soviets tried their own men at Khabarovsk. Ishii died in Japan in 1959. Fort Detrick kept the notes.

I will tell you everything needed.

2. Date of Incident

Unit active 1930s-45. U.S. interviews 1947-48. Policy language 1947.

3. Location

Pingfang, Harbin, and later Tokyo desks. Approximate 45°36 N 126°38 E.

4. Official Narrative

Tokyo tribunal did not try Ishii. Official U.S. line at the time: intelligence value. Official Japanese silence lasted decades. Khabarovsk is the other court.

5. Witness Layer

Ishii. Fell, Hill, Victor. MacArthur's channel. SWNCC clerks.

These data are the only known scientifically controlled data on the use of biological agents on human beings.

6. Recovery Logistics

Interview notes. A 74-page Detrick compilation. No public warehouse of the Pingfang work.

7. Assessment

A bargain file. Sit it next to Paperclip without copying Paperclip. Rockets are one currency. Human infection tables are another. Keep the missing ribbon. Keep the practical result: the men were not in the dock that would have read the tables aloud. This is not a cryptid page. It is a desk that chose data over a court.

8. Materials & Remains

Declassified occupation paper. Khabarovsk record. Pingfang ruins.

9. Key Personnel

Ishii Shiro : The plant.

Norbert Fell : The 1947 interviews.

Camp Detrick : The inbox.

10. Aftermath

Ishii untried. The tables stayed in channels. Japanese public accounting came late and thin.

11. Current Archive Status

Status: Pingfang unit. 1947 Detrick interviews. No Tokyo dock for the principals. Data kept.

Confidence: High that 731 ran human work. High that Detrick interviewed the principals and that they were not tried at Tokyo. Moderate that a formal immunity instrument was signed. Low that the data's later military value matched the claim used to hide it.

Filing note

A demolished plant, a general who lived, Detrick men with questions, a cable that said keep it off the docket, a committee that called the tables unique. Paperclip took engineers. This took infection notes.

Keep it in intelligence channels. Not a slogan. A filing instruction that decided who would stand up in court and who would not.
