Feldman, Herbert, From Crisis to Crisis: Pakistan 1962-1969 , London, Oxford University Press, 1972, pp. 344 The main emphasis of this book is on Ayub Khan’s government, but chapter 9 ‘The last phase’ (pp. 237-71) covers the ‘132 days of uninterrupted disturbances’. Stresses the rioting and factionalised violence, but notes the importance of the urban working classes and the students.
