Eastern Command in 1971 war by deploying the troops at the border. Lieutenant-General Niazi volunteered for transfer to East Pakistan when Lieutenant-General Bahadur Sher declined the post. 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. 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. By September 1971, he was appointed the martial law administrator in order to provide his support to Governor
Abdul Motaleb Malik who appointed
a civilian cabinet. On the issue of the
1971 East Pakistan genocide, Niazi had reportedly told his public relations officer and
press secretary, Major
Siddique Salik, that "we will have to account every single rape and killing when back in (West) Pakistan. God never spares the Tyrant." The
Government of East Pakistan appointed Niazi as commander of the Eastern Command, and Major-General
Rao Farman Ali as their military adviser for the
East Pakistan Rifles and
Pakistan Marines. In a public message, Niazi was praised by Abdul Hamid Khan saying: "The whole nation is proud of you and you have their full support". No further orders or clarification was issued in regards to the orders as Niazi had been caught unawares when the Indian Army planned to launch a full assault on East Pakistan.
Surrendering of Eastern Command under the gaze of Indian Army's
Eastern Command's commander
Lt. Gen. J.S. Aurora (sitting beside Niazi), on 16 December 1971 in
Dhaka. When Indian Army soldiers crossed the borders and charged towards Dhaka, General Niazi panicked when he came to realise the real nature of the Indian strategy and became frantically nervous when the Indian Army successfully penetrated the defence of the East. According to testimony by Major-General Rao Farman Ali to the War Enquiry Commission, Niazi's morale collapsed as early as 7 December. Niazi broke down in tears that day when meeting Governor Abdul Motaleb Malik to deliver a progress report on the war. General Niazi, alongside with his deputy
Rear-Admiral Mohammad Shariff, nervously tried reassessing the situation to hold the Indian Army's penetration by directing joint army-navy operations with no success. The Pakistani military combat units found themselves involved in a
guerrilla war with the Mukti Bahini under
M. A. G. Osmani. On 6 December, the
Indian government extended
diplomatic recognition to
Bangladesh. By 8 December Indian troops reached the outskirts of Dhaka. Malik, Rao Farman Ali, and Niazi offered India a
conditional ceasefire which called for transferring power in East Pakistan to an elected civilian government, but without the surrender of the Eastern Command led by Niazi. The offer was rejected by India, and was called illegitimate by President Yahya Khan. Governor Abdul Motaleb resigned from his post and he took refuge with his entire cabinet at the Red Cross shelter at the
Inter-Continental Dacca on 14 December. Niazi agreed to surrender and sent a message to
Sam Manekshaw despite many army officers declined to obey, although they were legally bound. The Indian Army commanders, Lieutenant General
Sagat Singh, Lieutenant General J. S. Aurora, and Major-General Jacob arrived at Dhaka via helicopter with the surrender documents. Niazi in his book revealed that he was very depressed at the time of surrender and that he signed the instrument of surrender with a "very heavy heart". The revolver was reportedly stolen from the National Museum in 2003. Although it would come to light that the firearm stolen was not the real
"pistol" handed over by Eastern Wing Commander A.A.K. Niazi, the real .38 Bore
Revolver is currently in the safekeeping of the Indian Military Academy at
Dehradun. ==War prisoner, repatriation, and politics==
