Guevara was almost a pop idol to young people in the 1960s, when he became the glamorous international revolutionary of their dreams. His early death, of course, was a help in this deification, as it was with Elvis Presley or James Dean. However, this book represents a real find - the diaries kept by Guevara during his seven-month stay in the Congo in 1965. He went there by stealth, so that his official disappearance caused a stir both in Cuba and the wider world; and his intention, as usual, was to export revolution, this time to the newly independent Congolese. In spite of Guevara's evident energy and ideological drive, he did not achieve a great deal, and questions must remain about his sense of political realities and also of his organising capacity. However, the diaries are a fascinating footnote to history and a milestone to his eventual death in the forests of Bolivia.
