Operation Searchlight

Before 1971, Bangladesh and Pakistan were a single country. After a severe typhoon in Bangladesh (then East Pakistan) aid from Pakistan was slow to arrive and immediately later Pakistan decided to hold elections. Bangladesh had a bigger population so its own party won. The Pakistani military then responded by commencing Operation Searchlight. They imprisoned intellectuals, slaughtered thousands of Bangladeshi officers, students, and basically anyone with a way of assisting the Bangladesh party. They also obliterated any institution that could support refugees and raped thousands more. India alongside Bangladesh then got into action and after the war that ensued 93,000 Pakistani soldiers surrendered (biggest surrender since World War 2) before the Indian army. All in all 300,000 to 3,000,000, Hindus were targeted with many killed, raped and enslaved for 9 months before India declared war.
