>By the late 1940s and early 1950s the Forest Brothers were provided with supplies, liaison officers and logistical coordination by the British (MI6), American, and Swedish secret intelligence services. This support played a key role in directing the Baltic resistance movement, however it diminished significantly after MI6's Operation Jungle was severely compromised by the activities of British spies (Kim Philby and others) who forwarded information to the Soviets, enabling the MGB to identify, infiltrate and eliminate many Baltic guerrilla units and cut others off from any further contact with Western intelligence operatives.
>Though Philby claimed publicly in January 1988 that he did not regret his decisions and that he missed nothing about England except some friends, Colman's mustard, and Lea & Perrins Worcestershire sauce,[80] his wife Rufina Ivanovna Pukhova later described Philby as "disappointed in many ways" by what he found in Moscow. "He saw people suffering too much," but he consoled himself by arguing that "the ideals were right but the way they were carried out was wrong. The fault lay with the people in charge." Pukhova said, "he was struck by disappointment, brought to tears. He said, 'Why do old people live so badly here? After all, they won the war.'" Philby drank heavily and suffered from loneliness and depression; according to Rufina, he had attempted suicide by slashing his wrists sometime in the 1960s.
