183 Secret NOFORN Chapter 4 THE FATE OF FRANCIS GARY POWERS Downed U-2 pilot Francis Gary Powers underwent extensive interro gation at the hands of the Soviets. His instructions from the CIA on what to do in the event of capture were meager, and he had been told that he might as well tell the Soviets whatever they wanted to know because they could get the information from his aircraft anyway. Nevertheless, Powers tried to conceal as much classified information as possible while giving the appearance of cooperating with his cap tors. To extract the maximum propaganda value from the U-2 Affair, the Soviets prepared an elaborate show trial for Powers, which began on 17 August 1960. Powers continued to conceal as much information as possible, but, on the advice of his Soviet defense counsel, he stated that he was sorry for his actions. The Soviet court sentenced him to IO years' "deprivation of liberty," with the first three to be spent in • 01 pnson. During the next 18 months, confidential negotiations to obtain the release of Powers took place as the United States explored the possibility of trading convicted Soviet master spy Rudolf Abel for _Powers. These negotiations were conducted by Abel ·s court-ap pointed defense counsel, former OSS lawyer James Donovan. in cor respondence with Abel's "wife., (probably his Soviet control) in East Germany. In November 1961, Acting DCI Pearre Cabell wrote to Secretary of State Dean Rusk supporting such a trade, and on l 0 February 1962 the actual exchange took place in the middle of the Glienecke Bridge connecting East and West Berlin. As part of the deal, American graduate student Frederick Pryor, who had been jailed in East Germany for espionage, was released at another location. After Powers returned to the United States, he underwent exten sive debriefing, for many questions about his mission remained unan swered. To conduct the debriefing, the Agency immediately reconvened the Damage Assessment Team that had met for two months in the summer of 1960 to estimate what Powers knew about the overflight program and could have told Soviet interrogators. Given Powers' long involvement with the U-2 program, the team had concluded in 1960 that his knowledge was extensive and he had prob ably revealed most of it to the Soviets. After two weeks of debriefing Powers in February 1962, however, the team found that the damage was much less than had been estimated, and they were quite satisfied " Powers.
