In 1952, the Army disregarded the advice of a top officer and decided to hold open-air biological warfare tests at Fort McClellan in Anniston, Alabama. In those tests the Army used two different bacterial agents that seem to have led to elevated rates of pneumonia cases among Anniston residents that winter. The bacterial agents were delivered in gaseous plumes and bacterial-filled bombs. But no one in the general public knew about it -- until a reporter for The Anniston Star newspaper used the Freedom of Information Act in 1981 to get declassified documents and publish these astonishing details.
