Amber Dach, who spent 16 years in military intelligence, was the primary analyst assigned to Bergdahl’s case for the five years after he disappeared. She described how eager he was to help intelligence officials at a hospital in Germany days after he was returned to U.S. authorities. Although his voice was weak and raspy, he helped authorities and even drew diagrams in his downtime to bring to his next debriefing session.

Dach and another official who debriefed Bergdahl testified that his time in Germany was extended partly so he could offer additional time-sensitive intelligence.

“He was very motivated to just download all of the details that he recalled,” Dach testified. “It was a gold mine. It really reshaped the way we did intel collection in the area.”
