John Walker Lindh, also known as the “American Taliban,” is scheduled to be released from prison in May.

Lindh, who was captured in the initial phases of the Afghanistan War, was involved in a prisoner uprising that resulted in the death of CIA paramilitary officer Michael “Mike” Spann, the first American killed in the Global War on Terror.

At the time of his death, Spann was interrogating Taliban and al-Qaeda prisoners inside the Qala-i-Jangi fortress, near the town of Mazar-i Sharif. Spann was accompanied by another CIA officer and their Northern Alliance bodyguards. While the questioning was taking place in the fortress’ courtyard, some of the prisoners ran toward their guards and detonated hidden grenades. Soon, they found weapons, and a full-fledged firefight broke out. Spann was swarmed by dozens of terrorists and was killed. It took the Northern Alliance forces days and the support of Green Beret teams from the 5th Special Forces Group and British Special Boat Service (SBS) operators to quell the uprising.

Lindh, who has obtained Irish citizenship because of his maternal grandmother, plans to relocate to Ireland upon his release. “I don’t really know what to expect from the Irish government,” he said from his prison cell. “I know virtually nothing about them. I think the only reasonable way to present my case to them is to explain my unique circumstances that make my survival in the U.S. practically impossible.”
