Overview

This episode chronicles Soviet spy Ursula Kuczynski's infiltration of an American OSS operation during WWII and her eventual retirement from espionage in East Berlin. Through her agent network, she helped the Soviets capture American intelligence technology and atomic secrets, ultimately becoming one of the USSR's most successful spies before growing disillusioned with the communist system she served.

Operation Joan Eleanor: Infiltrating American Intelligence

In August 1944, Ursula Kuczynski orchestrates the infiltration of a new American OSS intelligence operation in Nazi Germany. Through her agent Erich Henschke, she connects German communist exiles with American Lieutenant Joseph Gould, who seeks anti-Nazi agents to parachute into Germany. The mission involves a revolutionary new radio communication system called Joan Eleanor, which allows direct contact between ground agents and aircraft overhead. Moscow sees this as a prime opportunity to embed double agents within American intelligence operations.

  • OSS Lieutenant Joseph Gould recruits German communist exiles to parachute into Germany as intelligence agents
  • The mission involves Joan Eleanor, a secret new communication system allowing agents to speak directly with aircraft overhead
  • Paul Lindner and other anti-Nazi Germans agree to the dangerous mission for $331 per month
  • Ursula Kuczynski, through agent Henschke, positions the recruits as double agents serving Moscow
" We parachute you into Germany ahead of the Allied advance. You blend in, you reconnect with people you trust and build small intelligence rings. Then report back on troop movements, industrial targets, civilian morale, transport links, anything that helps the Allied push. "
" If you're caught, the Germans won't treat you as soldiers. You could be killed. Although we will compensate your families if that happens. "

The Joan Eleanor System Captured

By March 1945, Paul Lindner has successfully parachuted into Berlin and uses the revolutionary Joan Eleanor handset to transmit intelligence about Nazi military targets directly to American aircraft circling overhead. However, as the Soviet Red Army closes in on the city, Lindner follows orders to bury the top-secret device at a predetermined safe house. Within days of Germany's surrender, a Soviet officer retrieves the buried technology, delivering America's cutting-edge spy communication system directly into the hands of Soviet military intelligence.

  • Lindner successfully uses the Joan Eleanor handset to report on Berlin targets including the Klingenberg power plant and marshalling yards
  • As Soviet forces take Berlin, Lindner buries the secret American communication device at a safe house between a plum tree and chicken coop
  • A Soviet Red Army officer recovers the buried OSS handset, providing the GRU with America's latest intelligence technology
" This handset is part of the OSS's secret radio communication system known as Joan Eleanor. Lindner can use it to communicate directly with the reconnaissance aircraft six miles above him. It's a wartime first, allowing two-way communication with spies behind enemy lines without relying on heavy and easily detected radio transceivers. "
