After General Tikka Khan had initiated the Operation Searchlight military crackdown in March 1971, many officers had declined to be stationed in the East and Niazi arrived in Dhaka on 4 April 1971 to assume the Eastern Command from Tikka Khan. Furthermore, the mass killing of Bengali intellectuals in 1971 at the University of Dhaka had made the East Pakistani people hostile towards the Pakistani military, which made it hard for Niazi to overcome the situation. On 10/11 April 1971, he headed a meeting of his senior commanders to assess the situation but, according to eyewitnesses, he used abusive language aimed at the Bengali rebels. From May through August 1971, the Indian Army trained Mukti Bahini led Operation Jackpot, a series of counter guerrilla campaigns against the Eastern Command, and Niazi began taking countermeasures against the Bengali rebellion. By June 1971, he sent reports on the rebellion and noted that 30,000 insurgents were hurriedly trained by India at the India-East Pakistan border. In August 1971, Niazi formulated a plan to defend the borders from the advancing Indian Army based on a "fortress concept" which mean converting the border towns and villages into a stronghold.
