Nasim was commissioned in the 2nd
East Bengal Regiment in 1965. He participated in the Liberation war of Bangladesh. He was promoted to the rank of major during the war. He fought under Sector 2 and later under S Force as the commanding officer of the 11 East Bengal Regiment. Both officers had issued statements expressing dissatisfaction with the country's situation. The president believed that they were involved in political activities with opposition parties. Nasim refused to comply. The next day, Biswas sacked him and sent soldiers to control the state radio and television stations. On noon that day, Nasim ordered soldiers of
Bogra,
Jessore and
Mymensingh divisions to march towards
Dhaka. The Ninth Infantry Division's Major General
Imamuzzaman Chowdhury, who commanded the division located closest to Dhaka, remained loyal to the president. He directed the removal of all boats and ferries from
Jamuna River in
Aricha port, so that Bogra and Jessore divisions could not cross the river. Nasim sent a contingent of troops with tanks to blockade the Dhaka-Mymenshing highway. This prevented Mymensingh Division Army from entering Dhaka. In the meantime,
Major General Mohammad Anwar Hossain, general officer commanding of the 33rd Infantry Division located in
Comilla, also came to the aid of the president. He mobilized a fully geared 101 Infantry Brigade, under the command of Brig. Shah Ikram (later Maj. Gen.) to Dhaka to fortify
Bangabhaban, the presidential palace. The 33rd Division was deployed, using an infantry battalion and a company of tanks from the 7th Horse Armoured Battalion at the Dhaka-Chittagong highway, to create a blockade against the 24th Infantry Division located in Chittagong. The government broadcast announcements asking all soldiers to stay at their own cantonment. After some hours, Mymensingh Division soldiers returned to their barracks. The Chittagong Division never mobilized towards Dhaka. The general officer commanding of the Chittagong Division realized that the military coup was highly unlikely to succeed. That night, Nasim was interviewed by the
BBC and, in reference to troop movements, he said that as army chief, he could move troops anytime he wanted. Nasim was arrested by the brigade commander of 14 Independent Engineers Brigade and put under house arrest in the army mess behind Army Central Library, Staff road, Dhaka Cantonment. Later the
Awami League government, which was elected to power in 1996, granted him a formal retirement. ==References==
