Sensing the imminent defeat, the occupation forces decided to make one final attack for crippling the emerging nation by eliminating its intelligentsia so that Bangladesh cannot make progress.
On December 12 in 1971, they created a blue print and made their auxiliary forces responsible to implement the heinous plan.
Most of these traitors and collaborators were the members of Islami Chatra Sangha, student organisation of Jamaat-e-Islami, which played a paramount role in killing intellectuals.
According to the plan, the Al-Badr forces abducted journalist Nizamuddin Ahmed and ANM Golam Mostafa from their residences that night. They never returned.
Meanwhile, Allied Force, comprising of Muktibahini (freedom fighters) and Indian army continued approaching towards Dhaka to encircle the city for making the enemy force bound to surrender.
In the face of their fierce attack, Pakistani troops either fled from the battle field or surrendered to them for saving their lives.
Fleeing Pakistani troops from Jamalpur and Mymensingh joined their compatriots in Tangail and made a strong resistance there.
The heroic freedom fighters of Sector 4 attacked Haripur which was liberated a day after a frontal battle. On the same day, Nilphamari, Gaibandha, Narsingdi, Sarishabari, Bheramara and Sreepur were freed.
President of National Awami Party (NAP) and Advisory Council of Mujibnagar Government Maulana Abdul Hamid Khan Bhasani thanked the government and people of India for their overwhelming support.
In a statement, Maulana Bhasani said that the last struggle of his life was to make Bangladesh independent and establish socialism.
Meanwhile, Allied Force’s airstrikes on Pakistani military base in Dhaka continued. The confined Dhaka residents were living in a state of suffocation.
Many left the city fearing a probable fierce battle as they were sure that the joint force will attack the Pakistanis any time. No newspaper was published from Dhaka on the day.
Lt General Amir Abdullah Khan Niazi, Commander of Eastern Command of the Pakistan Army, said that the Pakistan army would fight for every single inches of land as long as a single troop lived.
Pakistan’s newly appointed Prime Minister Nurul Amin told India to leave ‘East Pakistan’. He said that people of ‘East Pakistan’ are determined to fight till the end. Nothing would break Pakistan, he added.
Radio Peking in China broadcast that it was the Union of Soviet Socialist Republics (USSR) who wanted to attack China by unleashing India on Pakistan. It was the reason for the Soviet Union to support the so-called Bangladesh, it added.
In the face of repeated refusal of the proposal of cease-fire, the US National Security Adviser Henry Kissinger outlined a new proposal.
According to that plan, on this day in 1971, the US representative in the UN Security Council George Herbert Walker Bush introduced a resolution which called for an immediate ceasefire, withdrawal of Indian and Pakistani force from each other’s territory, the creation of conditions necessary to safeguard the lives of civilians and safe return of refugees to their homes.
The Security Council voted 11-2 in favour of the resolution, with two abstentions. The resolution was not adopted because of the use of veto by the Soviet Union.
