The first use of waterboarding and other rough treatment against a prisoner from Al Qaeda was ordered by senior Central Intelligence Agency officials despite the belief of interrogators that the prisoner had already told them all he knew, according to former intelligence officials and a footnote in a newly released legal memorandum.

The escalation to especially brutal interrogation tactics against the prisoner, Abu Zubaydah, including confining him in boxes and slamming him against the wall, was ordered by officials at C.I.A. headquarters based on a highly inflated assessment of his importance, interviews and a review of newly released documents show.

Abu Zubaydah had provided much valuable information under less severe treatment, and the harsher handling produced no breakthroughs, according to one former intelligence official with direct knowledge of the case. Instead, watching his torment caused great distress to his captors, the official said.
