From Strange Rebels: 1979 and the Birth of the 21st Century, by Christian Caryl (Basic Books, 2014), Kindle Loc. 4181-4218:
The Polish secret police, the SB, and its Politburo masters created a special operation called LATO ’79. (Lato means “summer.”) As archbishop of Kraków, Wojtyła had already spent nearly twenty years as the focus of a considerable intelligence-gathering effort by the SB as well as, intermittently, the KGB, the East German Stasi, and other East-bloc secret services. LATO ’79 drew most of its operational intelligence from seven moles who had served in the archbishop’s immediate entourage over the years. They included both priests and laymen; one of them, code-named JUREK, was a member of the church organizing committee. Every possible measure to limit the effects of the pope’s visit was considered. Tens of thousands of police would be deployed in the course of the nine days. The SB informants who were involved in trip planning were advised, for example, to express worries about safety wherever possible (in the hope that this calculated disinformation would reduce the number of pilgrims). No effort was spared. In the event, 480 SB agents were deployed during the four days the pope spent in Kraków during the visit.
Presumably because a large number of East German Catholics also expressed a desire to see the pope, the East German secret police, the Stasi, deployed hundreds of its own agents to cover the event. The East Germans even set up a special headquarters post on the Polish border to coordinate their operations. The famous Stasi master spy Markus Wolf had planted his own mole inside the Vatican, a German Benedictine monk whose identity was not even known to the Stasi man in charge of the operation.
The apparatchiks were especially intent on managing the media coverage. In the weeks leading up to the visit, official media issued a stream of warnings. People should stay away from the pope’s events, the government urged: chaos and hysteria were sure to reign, and spectators could almost certainly count on being trampled to death. Foreign reporters were charged exorbitant accreditation fees, which excited a great deal of angry complaint and undoubtedly boosted the country’s desperately needed hard-currency reserves. But it doesn’t seem to have kept many journalists away. Domestic reporters were easier to deal with. The party issued reams of carefully considered guidelines and talking points. TV cameramen attended special training sessions. Their instructors told them to avoid shots of large crowds. Instead, they were supposed to point their cameras toward the sky while leaving a few people at the bottom of the frame. Shots of elderly people, nuns, and priests were to be preferred; young people, families, and laypeople should be avoided. The idea was to make it appear as though the pope’s supporters were a marginal, backward bunch, and certainly nothing like a cross-section of society.
Meanwhile, the party was taking no chances. In the weeks before John Paul II’s arrival, the Polish police arrested 150 dissidents—including Adam Michnik and Jacek Kuron, one of the founders of KOR [Workers’ Defence Committee]. (A few weeks earlier a gang of toughs had attacked Kuron on the street and beaten him badly. No one was charged in the assault—a fact that suggested the complicity of the security services.) Another one of those detained was a Catholic activist named Kazimierz Switon, who was sentenced to a year in jail for the peculiar crime of attempting to set up an independent trade union. This was an intolerable offense in a country that claimed to be run with the interests of the workers at its heart. Surely, the dictatorship of the proletariat obviated the need for any new labor movements outside of the state.
But appearances were deceptive. In fact, by the end of the 1970s, the essential schizophrenia of life was firmly established. Publicly, officially, there was the Poland of Communist Party rule: a place of grandiose slogans, lockstep marches, and central planning. This nation coexisted with an alternative Poland defined by opposition-organized “flying universities,” underground publications from dissident groups like KOR, and the parallel moral universe embodied by the Catholic Church, long linked with the struggle to assert Polish nationhood. Poles of this era had grown up in a society were life was split into two parallel realms, the public and the private, each with its own versions of language and history. As in so many other authoritarian states, citizens of the People’s Republic of Poland learned from early on to parrot their allegiance to official ideology in public while keeping their real opinions to themselves and their families. Communist rule depended on ensuring that people persisted in paying public tribute to the official version of truth, thus preventing them from seeing how many of them actually rejected it. But what would happen when they were allowed to make their private feelings manifest, on a mass scale?
