The arrival of the cargo ship MV Swat at Chittagong Port in late February 1971 served as the flashpoint for a series of events that would fundamentally alter the course of Bangladesh’s history.
Officially documented as carrying food grains, the vessel anchored at Jetty 17 on 28 February, but was actually transporting a massive cache of nearly 10,000 tonnes of arms, ammunition, and explosives for the Pakistani military.
Bengali staff in Karachi had alerted officials in Chittagong of the ship’s true contents, sparking immediate and sustained civil resistance.
Port labourers and local residents, often armed only with sticks and iron rods, besieged the ship to prevent the unloading of weapons intended for use against them.
By early March, Chittagong was in a state of high tension, further exacerbated by a violent riot between Bengalis and Urdu-speaking Biharis on 03 March.
During this volatile period, Major Ziaur Rahman served as the Second-in-Command (2IC) of the 8th East Bengal Regiment (8 EBR), the only Bengali army unit stationed in Chittagong.
While the regiment was under orders to transfer to Multan and was severely depleted of manpower, Zia and other Bengali officers held secret meetings at the Circuit House and Niaz Stadium to coordinate potential responses to a military crackdown.
The standoff over the MV Swat reached a critical juncture on 24 March 1971.
When the Pakistani army attempted to force port workers to unload the ship at gunpoint, East Pakistan Rifles (EPR) personnel refused orders to fire upon the protesters.
In response, the Pakistani military shot seven EPR members on the spot.
Throughout the city, thousands of people erected barricades and dismantled parts of the Shuvapur Bridge to block the movement of arms from the port to the cantonment.
As the standoff intensified, the Punjabi Commandant of the East Bengal Regiment Centre (EBRC), Brigadier Ansari, sought a solution that would bypass the civilian resistance.
He calculated that using a senior Bengali military officer to oversee the transport of the weapons might pacify the crowds and ensure the safe arrival of the arms at the Cantonment.
Ansari decided to task the 8th East Bengal Regiment, then stationed at Sholashahar, with the mission.
The responsibility fell upon Major Ziaur Rahman, the Second-in-Command (2IC) of the unit.
Records indicate that Zia was deeply reluctant to accept what he officially termed a “troop-fatigue” job, arguing that he had more pressing administrative and training tasks within his unit.
The real reason for his reluctance perhaps was rooted in a more profound concern: he was acutely aware that these weapons would ultimately be used by the Pakistani military against Bengali civilians.
Despite his objections, Zia was forced to comply under the direct insistence of his Commanding Officer, Lieutenant Colonel Rashid Janjua, a West Pakistani officer.
To ensure Zia followed through, a Punjabi Naval Lieutenant was dispatched from Patenga to escort him, and Colonel Janjua assigned an additional Punjabi Captain to the convoy.
According to many historical analysts, this mission was intended to be Zia’s final journey, a ploy to separate the senior Bengali officer from his troops during the impending military crackdown.
As Zia’s convoy moved slowly toward the port on the night of 25 March 1971, the Pakistani military launched Operation Searchlight—a coordinated genocidal campaign across East Pakistan.
In Chittagong, marauding forces began an assault on the Cantonment and were advancing toward the 8th East Bengal Regiment at Sholashahar.
Major Zia’s progress toward the port was severely impeded by the very barricades the public had erected to stop the MV Swat’s cargo.
While his convoy was halted near Agrabad, just ahead of the Dewanhat level crossing, Captain Chowdhury Khaliquzzaman rushed from the unit base to find him.
Khaliquzzaman found a pensive Major Zia standing by a running navy truck, watching as soldiers and sailors worked to clear a path under the supervision of the Punjabi officers.
In a hushed conversation, Khaliquzzaman apprised Zia of the dire situation: the massacre had begun in the Cantonment, and the 8th East Bengal Regiment was ready and awaiting his orders.
Zia reportedly immersed himself in deep thought, processing the betrayal of the military command and the start of the war.
After a brief silence, he delivered a definitive but suppressed roar: “In that case, we revolt”.
Recognizing the need for immediate action, Zia and Khaliquzzaman executed a swift tactical deception to rid themselves of the Pakistani escort.
Khaliquzzaman casually approached the Punjabi officers and informed them that he had brought a fresh message from Commandant Ansari and Colonel Janjua.
He claimed the orders had changed; the 8th East Bengal troops were no longer required at the port and Zia was to report back to his unit immediately.
The Naval officer, suspecting no foul play, gathered his sailors and departed for his base at Patenga.
Zia immediately ordered the convoy to return to the unit’s base at Sholashahar.
Upon arrival at the unit, Zia quickly took a rifle from one of the soldiers and arrested Azam.
Other Pakistani officers were also arrested immediately and sent to the Quarter Guard (unit prison) under commando Havildar Shafi.
Zia was so angry with Janjua that he went to arrest him personally.
As Janjua came out in a sleeping suit, Zia grabbed his shirt collar and said, “You sent me to the port to be killed!”
Witnesses describe a heated confrontation where Zia, fueled by the perceived betrayal, grabbed Janjua by the shirt collar and accused him of sending him to the port to be killed.
Janjua and other non-Bengali officers were promptly arrested and sent to the unit’s quarter guard.
