Archivist Challenges Kremlin in Wallenberg Saga A former senior Russian archive official says he saw a file that could shed light on Holocaust hero Raoul Wallenberg's fate - challenging the insistence of Russia's KGB successor agency that it has no documents regarding the man who saved tens of thousands of Jews in Hungary before disappearing into the hands of Soviet secret police. Anatoly Prokopenko, 78, told The Associated Press that in 1991 he saw a thick dossier containing numerous references to Wallenberg that suggested he was being spied upon by a Russian aristocrat working for Soviet intelligence. Russian officials later said the file didn't exist, in line with blanket denials of having information on Wallenberg. "That file is extremely interesting, because it could allow us to determine the reasons behind his arrest," Prokopenko said, while acknowledging he had only a few minutes to flip through hundreds of pages of documents. As Sweden's envoy to Nazi-occupied Hungary, Wallenberg saved 20,000 Jews by giving them Swedish travel documents or moving them to safe houses, and managed to dissuade Nazi officers from massacring the 70,000 inhabitants of the city's ghetto. The 32-year-old diplomat was arrested by the Soviets in January 1945 when the Red Army stormed Budapest, and imprisoned in Moscow. The Soviets had stubbornly denied that Wallenberg was in their custody before issuing a 1957 announcement that he had died on July 17, 1947, in his prison cell of a sudden heart attack. They stonewalled international demands for information about his fate, and rejected allegations that Wallenberg could have lived as a prisoner under a different identify as late as the 1980s. Prokopenko said that in the fall of 1991, on an inspection tour of the main KGB archive in a tightly guarded facility outside Moscow, he came across a hefty dossier on Count Mikhail Tolstoy-Kutuzov, a Russian aristocrat who left Russia after the 1917 Bolshevik Revolution and worked alongside Wallenberg in Budapest. Prokopenko said that he only had a few minutes to peek at the dossier, but he saw Wallenberg's name mentioned repeatedly in what appeared to be Tolstoy-Kutuzov's reports to his handlers in Soviet intelligence. "I realized that he was following every step Wallenberg made," Prokopenko said. Prokopenko was fired just over a year later and deprived of his access to the archives - a move Prokopenko attributes to his efforts to reveal secret Soviet archives to the public. He said he advised Guy von Dardel, Wallenberg's half-brother who spent years searching for clues to his fate, to ask the KGB successor agency for permission to see the files on Tolstoy-Kutuzov. They turned him down, saying that no such files existed. When von Dardel said that he knew from Prokopenko that this wasn't true, officials asked him to come back in a few days and handed him a dossier that contained only a few pages lacking any reference to Wallenberg. Prokopenko said that Stalin's secret police possibly suspected Wallenberg of being involved in secret contacts between the Western allies and the Nazis and were eager to learn about his connections. Wallenberg had been recruited for his rescue mission in Budapest by a U.S. intelligence agent, with Swedish government approval, on behalf of the War Refugee Board created by President Franklin D. Roosevelt. But he is not known to have been engaged in intelligence-gathering.
