I haven't read about Afghanistan in the 1960s
I did enjoy reading Field Marshal Frederick Sleigh Roberts, 1st Earl Roberts, VC, KG, KP, GCB, OM, GCSI, GCIE, KStJ, VD, PC, FRSGS book "Forty-one years in India, from subaltern to commander-in-chief" years ago with its description of The Battle of Kandahar and defeat of Ayub Khan, 9/1/1880
