On November 4, 1979, "student" supporters of the Ayatollah seized the U.S. Embassy with over sixty hostages. Although the Cold War was in full swing, the Iran hostage crisis was a watershed for the United States.
Detachment A had been established in Berlin early in the Cold War to harass and delay any Soviet military advance west. This Special unit trained relentlessly for every aspect of unconventional warfare, and was later assigned a second mission of counterterrorism.
The plan for Operation Eagle Claw, as it became known, was extremely complex. The first stage was intelligence gathering—no mean feat as most of the CIA's capabilities in the country had been eliminated. With operatives trained in intelligence work, fluent in many languages, and adept at blending in, Det A took on the advanced recon of the targets. Then, when Delta Force admitted that it could only manage the assault of the Embassy, Det A volunteered to rescue the three Americans at the Foreign Ministry.
Veteran and historian James Stejskal details Det A's unique and integral role in Operation Eagle Claw, based upon firsthand accounts of the operatives involved.
