Sometime after midnight on June 30, 2009, Pfc. Bowe Bergdahl left behind a note in his tent saying he had become disillusioned with the Army, did not support the American mission in Afghanistan and was leaving to start a new life. He slipped off the remote military outpost in Paktika Province on the border with Pakistan and took with him a soft backpack, water, knives, a notebook and writing materials, but left behind his body armor and weapons — startling, given the hostile environment around his outpost.

That account, provided by a former senior military officer briefed on the investigation into the private’s disappearance, is part of a more complicated picture emerging of the capture of a soldier whose five years as a Taliban prisoner influenced high-level diplomatic negotiations, brought in foreign governments, and ended with him whisked away on a helicopter by American commandos.
