Brian:
 
New South Associates did an extensive inventory of the buildings and
structures at Fort McClellan, Alabama.  Fort McClellan had a fairly large
POW camp number approximately 3,000 POWs, most of these were Italian and
German POWs.  This POW camp was built in May 1943.  The camp was laided out
in three sections, having rows of barracks within each section.  The camp
was essentially self-contained, featuring kitchens, orderly rooms,
dayrooms, dispensaries, a library and a reading room, chapel, open air
stage and atheletic fields.  The layout appears to have been a standard POW
camp plan devised by the Corps of Engineers and Quartermaster Corps.
Unfortunately none of these buildings survived, but from photos they appear
to be similar to the "Theater of Operation" buildings consisting of wood
framed single story, front gable rectangular structures with "tar paper
siding".  The use of "tar paper" was adquate for the south, but wood siding
may have been substitued in the north.
 
Responsibility for POW's (under the control of the Army) was delegated to
the Provost Marshal General Office, Prisoner of War, Special Projects
Divisions.  They were responsible for inspecting the camps, and I believe a
number of these reports still survive, they are probably available at the
National Archives in Washington or the National Archives, Military Branch
Suitland, Maryland.
