The fire began on the sixth floor of the National Personnel Records Center in St. Louis, Missouri. It burned for 22 hours on July 12, 1973. Firefighters poured millions of gallons of water into the building. The entire sixth floor, a single open space the size of three American football fields, was consumed. The heat was so intense it fused stacks of paper into solid, charred blocks. The fire destroyed approximately 16-18 million Official Military Personnel Files.
The loss was not random. The sixth floor held the Army records for personnel discharged between 1912 and 1959, and the Air Force records for those discharged between 1947 and 1963. The records of World War I, World War II, and the Korean War were the core of the devastation. The cause was never definitively determined, though faulty electrical wiring was suspected. There were no sprinklers in the storage area.
The consequence was a bureaucratic nightmare that persists. Veterans and their families needing to prove service for benefits, medals, or burial rights suddenly found the primary source gone. The National Archives launched a massive reconstruction effort, using alternate sources like payroll records and medical files to create substitute documentation. This process, called the Reconstruction Program, continues today.
The event is obscure to the public but legendary in archival and genealogical circles. It stands as one of the worst losses of government records in history. Its legacy is a permanent gap in the national memory, a lesson in the vulnerability of paper, and a cautionary tale that has since driven reforms in how vital records are stored and protected.
