Series II contains the general manager's file on government-owned ordnance facilities built and operated by DuPont during World War II. These files are arranged in seven sub-series that reflect the original filing system maintained by the Explosives Department. Included in this series are contracts for the design, construction, and operation of plants for the manufacture of smokeless powder; trinitrotoluene and other materials essential to the war effort; and supplemental agreements and change orders for the contracts. In addition, there is an extensive body of correspondence with the staff of the department's Military Explosives Division, as well as the Army Ordnance Department's field director of ammunition plants, regarding the status of these projects. The bulk of these records are files from Edward B. Yancey's tenure as general manager. Upon his retirement in 1944, Yancey was succeeded by William H. Ward.
