a quick study on insurgency failures. According to the documents, the CIA began dropping small guerilla units into China, the first Third Force team having been deployed in April, 1952. All four members of the team were never heard from again. The second Third Force team was made up of five ethnic Chinese agents, and dropped into the Jilin region of Manchuria in mid-July 1952. The team eventually reported contact with local rebel leaders. The team was, unbeknownst to the CIA, captured and turned by the Chinese, setting up the ensuing trap. The CIA responded by sending in a rescue unit, only to have its planes shot down and its principal agents assigned to the mission, Jack Downey and Dick Fecteau, arrested. Both men were subsequently sentenced to prison sentences in China. Beijing later boasted of the insurgency failures of their United States counterparts.

A joint CIA and FBI counterintelligence operation set up to investigate the intelligence failure advanced three different theories as to why the spy network was dismantled: (1) there was a mole within the CIA, (2) "sloppy tradecraft" and (3) PRC intelligence agents had hacked the covert system the CIA used to communicate with its foreign sources. The New York Times said that the debate over the cause remained unsolved while the a former American intelligence official cited by Foreign Policy said investigators concluded that it was caused by
