others are partial and mutilated. Information that is still currently classified includes key reports in Churchill's records, including the PREM 3 file in the UK's Public Records Office, which contains Churchill's most secret wartime intelligence briefs. In it, the 252 group dealing with the Japanese situation in 1941 is open, save for the omission of Section 5, dealing with events from November 1941 through March 1942, and is marked with official finality as "closed for 75 years." Unlike the Magic intelligence files released by the United States, none of the Ultra intelligence files pertaining to Japan have been released by the British government. Conflicting stories regarding FOIA (Freedom of Information Act) requests for the source materials used, e.g., Sheet Number 94644, or materials available at the National Archives are also common among the debate. However, much information has been said to have been automatically destroyed under a destruction of classified information policy during the war itself. Various authors have nevertheless continued to bring classified Pearl Harbor materials to light via FOIA. For instance, Sheet No. 94644 derives from its reference in the FOIA-released Japanese Navy Movement Reports of Station H in November 1941. Entries for 28 November 1941 have several more items of interest, each being a "movement code" message (indicating ship movements or movement orders), with specific details given by associated Sheet Numbers. Examples are: Sheet No. 94069 has information on "KASUGA MARU" – this being hand-written (Kasuga Maru was later converted to CVE Taiyo); Sheet No. 94630 is associated with IJN oiler Shiriya (detailed to the Midway Neutralization Force, with destroyers Ushio and Sazanami, not the Kido Butai); and finally for Sheet No. 94644 there is another hand-written remark "FAF using Akagi xtmr" (First Air Fleet using Akagi'''s transmitter). It is known that the movement reports were largely readable at the time. These three documents (Sheet Numbers 94069, 94630, and 94644) are examples of materials which yet, even after decades and numerous specific FOIA requests, have not been declassified fully and made available to the public. Sheet Number 94644, for example, noted as coming from Akagis transmitter and as being a "movement code" report, would have likely contained a reported position. Forgeries A purported transcript of a conversation between Roosevelt and Churchill in late November 1941 was analyzed and determined to be fake. There are claims about these conversations; much of this is based on fictional documents, often
