This PURSUE Release 01 document record points to a Department of War PDF titled for SHAEF numeric files from 1944-1945 and German armament equipment documents.1 The release metadata places the incident context in Germany on March 18, 1945.1
SHAEF Wartime Files
SHAEF was the Supreme Headquarters Allied Expeditionary Force, the Allied command structure that coordinated operations in northwest Europe during the final phase of World War II.2 The file title places this material inside Record Group 331, the National Archives group for Allied operational and occupation headquarters records from that war.2
415th Night Fighter Reports
The release summary says the file contains SHAEF messages and memorandums about "night phenomena (foofighters)," flak rockets, unidentified cylindrical objects, and blinking lights.1 It also says the documents repeatedly reference observations from the 415th Night Fighter Squadron, giving the record a direct aircrew-reporting context rather than a later folklore-only origin.1
Allied Intelligence Framing
This record matters because it anchors foo-fighter and night-phenomena language inside wartime military reporting channels. The release does not resolve the observations, but it shows how Allied intelligence handled unusual aerial reports alongside possible enemy weapons and battlefield air-defense concerns.3
