Before I became a chronicler of the men detained without charge or trial in the US prison at Guantánamo Bay, Cuba, I wrote a book about the British counter-culture, Stonehenge: Celebration and Subversion, which told the story of Britain’s most iconic ancient monument from the point of view of those who have sought to make it their own in the face of opposition from the government and the archaeological establishment: festival-goers, travellers, anarchists, eco-activists, Druids and other pagans. I also compiled, edited and contributed chapters to The Battle of the Beanfield, produced to commemorate the 20th anniversary of that brutal day in June 1985, when, having destroyed Britain’s mining communities, Margaret Thatcher turned her jack-booted attention to another “enemy within”: the travellers and political activists who had replicated the Greenham Women’s anti-nuclear protest at Molesworth in Cambridgeshire, and who were viciously set upon by police from six counties — and the Ministry of Defence — as they tried to make their way to Stonehenge to establish what would have been the 12th annual free festival, an anarchic free-for-all, the likes of which are now but a distant memory.
