NO one expected anything more than a notional Partition. A lot of my Mends from Uttar Pradesh serving in the ICS shifted to Pakistan, firm in their belief that they could serve their tenure in this "backward" place that needed administrators and then come back to retire in Allahabad and Lucknow. At worst you expected a India-Nepal, US-Canada kind of situation. If I recall correctly, as late as early 1947, Nehru in a radio speech talked of the "possibility" of Partition and the "promise" of Independence. Gandhi's reaction: sarvanaash (disaster). Which is exactly what followed. The fury of those riots could have been mitigated had the announcement come a little less suddenly. Sultana and I didn't see much of the riots, barring a minor one at Saunders Road in Bombay but we did hear the horror stories about Delhi, Calcutta, Punjab.
