Ever since its foundation in 2002, the Guantanamo Bay Detention Facility has become the symbol for many people around the world of all that is wrong with the 'war on terror'. Secretive, inhumane, and illegal by most international standards, it has been seen by many as a testament to American hubris in the post-9/11 era.

Yet until now no one has written about the most revealing part of the story - the prison's first 100 days. It was during this time that a group of career military men and women tried to uphold the traditional military codes of honour and justice that informed their training in the face of a far more ruthless, less rule-bound, civilian leadership in the Pentagon. They were defeated. This book tells their story for the first time.

It is a tale of how individual officers on the ground at Guantanamo, along with their direct superiors, struggled with their assignment from Washington, only to be unwittingly co-opted into the Pentagon's plan to turn the prison into an interrogation facility operating at the margins of the law and beyond.
