As such, even after the British left and East Bengal became a region of Pakistan, the Jessore Cantonment remained a powerful military base for the Pakistanis.

The next day, i.e. 7th December, the allied Bangladeshi and Indian forces prepared themselves to take the Jessore cantonment which was full of Pakistani tanks and Armory.

Sensing the approach of the enemy, the Pakistani Forces left the cantonment with all their arsenals and tanks and moved almost fifty-four kilometers towards Shiromoni of the Khulna Division.

Apart from these, from the cable factory to Daulatpur, the Pakistanis set up huge number of bunkers and landmines which established a strong defensive position for them.

On the other hand, after finding the Jessore cantonment completely empty of enemy troops on 7th December, the Bangladeshi and Indian forces got to know that the Pakistanis have taken position at Shiromoni.

After this, Sector VIII of Mukti Bahini under the command of Major Muhammed Abul Manzur began to march towards Khulna and on 11th December took position at Fultola near Shiromoni to prepare for an offensive against the Pakistani forces.

By this time, since Khulna, Jessore, Faridpur and Kushtia had been liberated from Pakistani forces, Mukti Bahini from all these areas began to surround Shiromoni from all directions.

The Mukti Bahini under the command of Major Manzur started to fire heavily with machine guns at Pakistani soldiers stationed at Shiromoni.

Thus, with moments of brief ceasefires, the battle continued for days till 17th December, even though the commander of all Pakistani forces in Bangladesh, Lieutenant General Amir Abdullah Khan Niazi surrendered to joint Indian and Bangladeshi forces at Dhaka on 16th December (which officially ended the Bangladesh Liberation War and Indo-Pakistani War of 1971).

Even though the Instrument of Surrender signed by Lt. General Niazi clearly stated that, “The PAKISTAN Eastern Command agree to surrender all PAKISTAN Armed Forces in BANGLA DESH to Lieutenant-General JAGJIT SINGH AURORA, General Officer Commanding in Chief of Indian and BANGLA DESH forces in the Eastern Theatre.

After a military meeting of ten minutes, it was decided that Major Manzur will be in command of the joint Bangladeshi and Indian forces at Shiromoni and Fultola.

[6] On that day, at around 1:30 pm, Brigadier Hayat Khan, along with his 3,700 men,[11] officially surrendered to joint Bangladeshi and Indian Forces on the premises of Khulna Circuit House.
