Operation Searchlight was a planned military operation carried out by the Pakistan Army to curb the Bengali nationalist movement in the erstwhile East Pakistan in March 1971, which the Pakistani state justified on the basis of anti-Bihari violence by Bengalis in early March.  Ordered by the central government in West Pakistan, this was seen as the sequel to "Operation Blitz" which had been launched in November 1970.  The original plan envisioned taking control of the major cities on 26 March, and then eliminating all opposition, political or military, within one month.  President Yahya Khan at a conference in February 1971 said "Kill three million of them and the rest will eat out of our hands."
