see him, being regularly imprisoned for political activity, and his daughters first visited in December 1975. Winnie was released from prison in 1977 but was forcibly settled in Brandfort and remained unable to see him. From 1967 onwards, prison conditions improved. Black prisoners were given trousers rather than shorts, games were permitted, and the standard of their food was raised. In 1969, an escape plan for Mandela was developed by Gordon Bruce, but it was abandoned after the conspiracy was infiltrated by an agent of the South African Bureau of State Security (BOSS), who hoped to see Mandela shot during the escape. In 1970, Commander Piet Badenhorst became commanding officer. Mandela, seeing an increase in the physical and mental abuse of prisoners, complained to visiting judges, who had Badenhorst reassigned. He was replaced by Commander Willie Willemse, who developed a co-operative relationship with Mandela and was keen to improve prison standards. By 1975, Mandela had become a Class A prisoner, which allowed him greater numbers of visits and letters. He corresponded with anti-apartheid activists like Mangosuthu Buthelezi and Desmond Tutu. That year, he began his autobiography, which was smuggled to London, but remained unpublished at the time; prison authorities discovered several pages, and his LLB study privileges were revoked for four years. Instead, he devoted his spare time to gardening and reading until the authorities permitted him to resume his LLB degree studies in 1980. By the late 1960s, Mandela's fame had been eclipsed by Steve Biko and the Black Consciousness Movement (BCM). Seeing the ANC as ineffectual, the BCM called for militant action, but, following the Soweto uprising of 1976, many BCM activists were imprisoned on Robben Island. Mandela tried to build a relationship with these young radicals, although he was critical of their racialism and contempt for white anti-apartheid activists. Renewed international interest in his plight came in July 1978, when he celebrated his 60th birthday. He was awarded an honorary doctorate in Lesotho, the Jawaharlal Nehru Award for International Understanding in India in 1979, and the Freedom of the City of Glasgow, Scotland in 1981. In March 1980, the slogan "Free Mandela!" was developed by journalist Percy Qoboza, sparking an international campaign that led the UN Security Council to call for his release. Despite increasing foreign pressure, the government refused, relying on its Cold War allies US president Ronald Reagan and British prime minister Margaret Thatcher; both
