fourth part of The Gulag Archipelago ("The Soul and Barbed Wire"). The narrative poem The Trail (written without benefit of pen or paper in prison and camps between 1947 and 1952) and the 28 poems composed in prison, forced-labour camp, and exile also provide crucial material for understanding Solzhenitsyn's intellectual and spiritual odyssey during this period. These "early" works, largely unknown in the West, were published for the first time in Russian in 1999 and excerpted in English in 2006. Marriages and children On 7 April 1940, while at the university, Solzhenitsyn married Natalia Alekseevna Reshetovskaya. They had just over a year of married life before he went into the army, then to the Gulag. They divorced in 1952, a year before his release because the wives of Gulag prisoners faced the loss of work or residence permits. After the end of his internal exile, they remarried in 1957, divorcing a second time in 1972. Reshetovskaya wrote negatively of Solzhenitsyn in her memoirs, accusing him of having affairs, and said of the relationship that "[Solzhenitsyn]'s despotism ... would crush my independence and would not permit my personality to develop."

She contended that it was, rather, a collection of "camp folklore", containing "raw material" which her husband was planning to use in his future productions. In 1973, Solzhenitsyn married his second wife, Natalia Dmitrievna Svetlova, a mathematician who had a son, Dmitri Turin, from a brief prior marriage. He and Svetlova (born 1939) had three sons: Yermolai (1970), Ignat (1972), and Stepan (1973). Dmitri Turin died on 18 March 1994, aged 32, at his home in New York City. After prison After Khrushchev's Secret Speech in 1956, Solzhenitsyn was freed from exile and exonerated. Following his return from exile, Solzhenitsyn was, while teaching at a secondary school during the day, spending his nights secretly engaged in writing. In his Nobel Prize acceptance speech he wrote that "during all the years until 1961, not only was I convinced I should never see a single line of
