Elkins emerged with a book that turned her initial thesis on its head. The British had sought to quell the Mau Mau uprising by instituting a policy of mass detention. This system – “Britain’s gulag”, as Elkins called it – had affected far more people than previously understood. She calculated that the camps had held not 80,000 detainees, as official figures stated, but between 160,000 and 320,000. She also came to understand that colonial authorities had herded Kikuyu women and children into some 800 enclosed villages dispersed across the countryside. These heavily patrolled villages – cordoned off by barbed wire, spiked trenches and watchtowers – amounted to another form of detention. In camps, villages and other outposts, the Kikuyu suffered forced labour, disease, starvation, torture, rape and murder.
