Partition in the West was a quick cut, a jhatka. It saw the trains with their cargoes of dead bodies crossing the new border in both directions. Then the survivors were left to pick up the pieces. In the East, it did not happen quite so abruptly. It went on in East Pakistan, after 1947. There were riots in 1948, 1949, and through the 1950s and 1960s. The 1950 Barisal riots were particularly severe. Apart from thousands killed, lakhs of Hindus became refugees. In 1964 again, there was a major round of rioting and another few lakh people were forced out. All of this led up to the 1971 genocide in which an estimated three million Bengalis were killed by the Pakistan army. Hindus were targeted in the genocide, which counts as one of the worst in world history.
