Chittagong
Chittagong housed the only oil refinery in East Pakistan, had a large fuel depot, was the largest seaport and MV Swat, with 9000 tons of arms and ammunition was in port. Bengali units substantially outnumbered the West Pakistani Chittagong garrison, which was a cause of concern for Pakistani planners. Bengali officers of EPR and EBR had discussed a preemptive strike on Pakistan forces, but the senior Bengali officers (Lt. Col M.R. Choudhury -Chief Instructor, EBRC) and Major Ziaur Rahman (2IC, 8 EBR), dissuaded Captain Rafiq (Sector Adjutant, EPR) from rebelling in the belief that the Pakistani army would not take action against civilians, but confirmed that they will revolt in case of any Pakistani attack. Attempts to unload arms and ammunition from MV Swat were a partial failure during March 20-25th, as civilian protestors blocked any attempt to take the arms to the cantonment and many were shot by the army. Brig. Mazumdar was relieved of his post because of this failure.
Pakistani units were given the following objectives in Chittagong:
Disarm EBRC units, 8 EBR, EPR and police units
Seize police armory, radio station and telephone exchange
Liaise with Pakistani Navy
Arrest Lt. Col. MR Chaudhury and Awami League leaders.
The Chittagong garrison was to be reinforced by the bulk of 53rd Brigade troops from Comilla on March 26.
Course of events:
March 25
The daytime witnessed nothing unusual, Pakistani and Bengali troops continued normal activities, while civilians barricaded streets to impede army movements. 1 Company of Bengali soldiers unloaded the MV Swat, all day and night, which would be finished by March 26 midday. Pakistani navy secured the airport just after dusk, capturing all EPR personnel stationed there. Commodore Mumtaj prevented any massacre of Bengali Naval personnel at the naval base but also ensured they cause no mischief.The port facility was secured by a Pakistani infantry company by 9:00 PM. Communication networks were partially shutdown.
Around 8:30 PM, Captain Rafiq (Sector Adjutant, EPR) was informed of troop movements in Dhaka. He immediately went to the EPR HQ and successfully took control of the facility by 10:30, imprisoning about 300 Pakistani EPR members, then sent a prearranged signal to all Bengali EPR companies attached to the Chittagong EPR sector to imprison all Pakistani soldiers and come to the city. This is the only instance where Bengali units launched a preemptive strike against the Pakistanis during the operation. Captain Rafiq deployed his troops in Agrabad (100 soldiers), Railway Hill (150) and Court hill (a platoon). The rest guarded the EPR HQ. The EPR Ramgarh contingent was told to blow up the Shuvopur bridge. As per his discussions with Lt. Col. Chowdhury and Major Zia, he had assumed they would take over the cantonment an assumption that would have fatal consequences.
20 Baluch, under Lt. Col Fatami, sent 6 truck loaded with troops to secure EBRC around 11:30 PM. They achieved total surprise and killed over 1000+ Bengali troops and secured the area by 3:30 PM. (Islam pp. 105106) Lt Col. M.R. Chowdhury was among those killed, while surviving Bengali personnel were scattered. Pakistani forces had partially achieved their objectives by securing the cantonment, the port and the airport, and they awaited reinforcements from Comilla before taking further steps.
8 EBR troops at Sholoshahar were unaware of the attack on EBRC. Major Ziaur Rahman was away, making his way to port to unload ammunition from MV Swat around 11:45 PM while Major Mir Shawkat Ali had been ordered to take a company to the port. When some of the EBRC survivors reached 8 EBR lines begging for help, Captain Khalekuzzaman raced to find Zia while Captain Oli Ahmad began recalling EBR troops to Sholoshahar and arrested all Pakistani soldiers and officers of the unit. Captain Khalek managed to find Maj. Zia and get his escort of Pakistani troops back to 8 EBR lines, where Zia managed to arrest his escort and order Bengali troops to move out. Bengali officers were divided in their opinion, some wanted to take on the 20 Baluch at EBRC to save Bengali lives, but ultimately it was decided that such a move would be suicidal. 8 EBR left the city and took position across the Kalurghat bridge around 1:15 AM.Bengali troops killed all Pakistani prisoners including the CO, Lt. Col. Janjua prior to moving out.
Pakistani troops from the Naval base launched an unsuccessful attack on the EPR HQ in the early hours (2:00AM 4:00 AM) of March 26. Around 4:00 March 26, Major Bahar (CO 53rd Brigade Signal Company -Bengali), warned Captain Rafiq of 80 to 100 vehicles bearing the bulk of 53rd Brigade troops under Brig. Iqbal Shaffi was moving towards Chittagong. Captain Rafiq sent a EPR Machine gun platoon under Subadar Musa, with a mortar and rocket launcher to delay the Pakistani column near Kumira, 12 miles north of Chittagong.
By 11:30 PM Captain Haroon (2IC 17th EPR Wing) had taken control of the wing, put Pakistani personnel in jail, and had signaled EPR troops in border areas to move to Chittagong by 3:30 AM. Captain Haroon with his troops reached Kalurghat Bridge by 26 March morning, where Major Zia ordered him to stay with the 8 EBR troops, along with 2 EPR companies coming from Teknaf Rangamati EPR Company imprisoned their Pakistani members and took position to the north east of cantonment by the early hours of March 26. Bengali plan of resistance had fallen apart, EPR troops were to remain without the expected reinforcements throughout the battle.
March 26
53rd Brigade detachment had moved out around 3:00 AM from Comilla, but was repeatedly faced delays on the way because of barricades, damaged culverts and other obstacles thrown up by civilians during their 100 mile journey to Chittagong, forcing them to stop and make makeshift repairs and diversion roads before moving on. They captured the partially damaged Suvapor Bridge intact around 10:00 AM then stopped to make repairs. Brig. Shaffi was ordered to make for Chittagong, so he resumed his advance with the infantry, commando troops and some mortars after midday, when his engineers put up a path across the ravine, leaving his engineers and mortar battery at Shuvopur. By 7 PM, March 26, this group had reached Kumira (Comeera), by which time Captain S.A. Bhuyan (after talking with Captain Rafiq over phone) of EBRC had reinforced the EPR Platoon at Kumira with 70 soldiers, and had divided his forces in 3 platoons to set up an ambush.
20 Baluch with some tanks had secured the area immediately around the cantonment in the morning. During the day Pakistani troops from naval base and EPR soldiers had several clashes inside the city, especially around the Agrabad area and the Railway hill resulting in Pakistani soldiers being bottled up in the naval base. Bengali positions in the city came under shellfire from Pakistani Naval ships and artillery, while Bengali troops at the port facility were disarmed around midday and shot before dusk.
Around 7 PM, Brig. Shaffis troops were ambushed near Kumira, losing 10 killed, and suffering almost 100 casualties, including Lt. Col. Shahpur Khan (CO 24 FF). Brig. Shaffi himself had to flee for the hills, and 2 truck full of arms were recovered by the Bengalis. Half the convoy was outside the ambush firing range and Pakistanis, commanded by Major Amzad Hussain (Bengali!!!) fought back, and a 2 hour long battle ensued. The mortars were handled by Captain Fazlur Rahman Bhuyan (Bengali), who ironically was a Kakul Academy batch mate of Captain S.A. Bhuyan, leading the Bengali ambush. The Pakistani column lost all contact with Comilla and the GHQ at Dhaka, raising fears that it had been wiped out, which, if true, might have crippled the Pakistani effort.
The EPR HQ and Railway hill came under intense bombardment by Pakistani naval ships (PNS Jahangir and 2 gunboats) and artillery during the day. Pakistani troops launched two attacks on the Railway hill and EPR HQ after a 2 hour barrage around 8:30 PM, but both attacks were repulsed. Pakistanis continued to shell both areas throughout the night.
At the end of March 26, both Pakistani and Bengali troops had been denied land based reinforcements. Pakistani troops were stuck at Kumira, while Major Zia was keeping any EPR troops heading to the city at Kalurghat. Pakistani troops were in control of the northern and southern part of the city, and they were getting reinforcements through the air. The 2nd SSG (CO: Lt. Col Sulayman) was flown to Chittagong, while ammunition was flown out to replenish Pakistani forces around the province. Bengali troops were stuck in the middle (literally and figuratively) so the lack of communication and coordination between Maj. Zia and Captain Rafiq meant Bengali positions would come under intense pressure. Maj Zia had decided not to enter the city until his forces were all organized, so 1000+ Bengali soldiers remained at Kalurghat. EPR troops from Ramgarh could not reach the city as Pakistanis stuck at Kumira barred their way, and the troops from Rangamati were stuck outside the cantonment. The Bengali soldiers in the city were in dire need of supplies and reinforcements.
March 27
Captain Rafiq and EPR troops withdrew from the Railway Hill position, and planning to join the EPR troops on the north of the cantonment before sunrise. Captain Rafiq planned to attack the cantonment and take over the supply dumps, but his troops moving towards the cantonment were taken to Kalurghat by Maj Zia enroute, scuttling this risky plan. Pakistani troops from the naval base moved through Agrabad towards the EPR HQ, but EPR troops managed to beat back the attack.
General Khadim, GOC East Pakistan flew to Chittagong cantonment in the morning and conferred with Col. Fatami, then tried to locate Brig. Shaffis troops flying along the Comilla-Chittagong highway by Helicopter. The helicopter was hit by small arms fire near Kumira, and returned to Dacca without making contact.Gen Khadim moved his HQ from Dhaka to Chittagong cantonment next, and sent a column of 20 Baluch to locate the 53rd Brigade troops, but this column clashed with the EPR troops north of the city and got bogged down. General Mitha arrived in Chittagong around midday via Helicopter and planned to send a commando platoon from 2 SSG under Lt. Col Sulayman to link up with 20 Baluch before going on to locate Brig. Shaffi.The platoon raced north from the naval base in 2 jeeps and 3 pickup trucks, but were ambushed near Double Mooring, losing 13 members including the CO.
Meanwhile Brig. Shaffi had regrouped his forces at Kumira, and the Pakistani soldiers from Shuvopur had joined him after leaving a rearguard on the bridge. He sent a column east to bypass the Bengali position and linkup with the 20 Baluch, but it was ambushed and forced to withdraw. Another column moving along the seashore was also ambushed, and some Pakistani soldiers lost their way and were killed by Bengali mobs. Bengali civilians had provided warnings which were crucial for setting up the ambushes. The EPR troops at Kumira were almost out of ammunition and fell back 5 miles south to Bhatiari. Captain Bhuyan left for the city to get supplies, but could not return to Kumira. Captain Rafiq finally managed to re-supply the troops, but it took 7 long hours. Later that day Capt. Rafiq left for Ramgarh to seek Indian assistance. In the meantime, EPR troops took control of Feni, thus cutting off the road link between Comilla and Brig. Shaffi. EPR troops at Ramgarh split in two groups, one moved to join the Bengali soldiers near the Chittagong cantonment, while the others made for Shuvopur.
At the Chittagong naval base Brig. Ansari formed a task force of 2 tanks, one infantry battalion and mortars to hold the port area, supported by the 2 SSG commandos and naval ships. He was later reinforced by another battalion flown from Dhaka. Pakistanis made another attack on the EPR HQ without success later in the day.
Major Zia kept his troops at Kalurghat bridge, broadcast a declaration of independence with himself as the provisional head of state in the evening. He later amended the message and declared independence on behalf of Sheikh Mujibur Rahman after consulting with Awami League leaders, and arranged to broadcast the message hourly.The impact of this broadcast, which were picked up by the civilians and isolated Bengali units fighting the Pakistanis, was significant. Gen. Mitha planned to send another commando platoon to blow up the station, but the fate of the first platoon convinced him to send this in speedboats instead of overland.
EPR troops attempted to capture the Shuvopur bridge without success. Pakistani troops had failed to take control of Chittagong as planned, but they had access to airborne reinforcements and no lack of supplies, while Bengali troops were running out of supplies, needed reinforcements and the lack of coordination between Maj. Zia and Captain Rafiq meant their effort were not fully effective. By 27 March, most Bengali troops outside Chittagong city had assembled near the Kalurghat bridge, away from the battle in the city, where Major Zia had set up command.
March 28
Pakistani forces at Kumira launched a 3 pronged attack on Bengali forces in the morning, supported by mortars and PNS Rajshahi and Balaghat from the sea. The attack broke through and surviving EPR troops retreated to Fauzdarhut, were they were joined by an EPR platoon. Brig. Shaffi soon began attacking the area around 8 AM. After a clash of 3 hours, Bengali troops fell back to a position near the Haji Camp, which soon came under attack from Brig. Shaffis troops.
The Pakistani commando platoon sent to blow up Kalurghat Radio station was cornered in the Agri Building near the river and wiped out. Gen. Khadim then ordered the 20 Baluch to attack the station, which was repulsed. 20 Baluch also unsuccessfully attempted to dislodge the EPR troops positioned to the north of the cantonment around midday. Pakistani troops managed to push south from the cantonment and take control of the Circuit house (this became the HQ for Gen. Khadim). Pakistani ships and artillery continued pummel Bengali positions, but Pakistani attempts from the naval base to drive the EPR from Agrabad and link up with the 20 Baluch failed, although 20 Baluch and Brig. Shaffis group made contact with each other later in the day.
Captain Bhuyan, who was posted at Kalurghat Radio station by Major Zia, made two Radio announcements. The first one was to observe a blackout, the second was for all Bengali armed forces personnel to gather at Laldighi Moydan. Realizing the danger from the PAF in an open air gathering, the second announcement was cancelled, which was mainly given to gather scattered Bengali troops in the city. Major Zia had not finished his reorganization so 1000+ Bengali troops still sat at Khalurghat. At night, nervous Bengali soldiers at Kalurghat radio station opened up twice at thin air, wasting much of their ammunition. EPR troops from Ramgarh, now commanded by Maj. Shamsuddin (CO 14th EPR Wing) attacked the Pakistani guard on Shuvopur bridge in the evening, wiping out the Pakistani contingent and capturing the bridge.
March 29
Brig. Ansari sent a Pakistani detachment from the naval base bypassing EPR positions at Agrabad and captured New market and DC hill in the morning, but they were repulsed at Court Hill. Brig. Shaffi, who had taken control of the Haji camp and linked up with the 20 Baluch, now pushed south to the edge of Agrabad and made contact with Brig. Ansaris detachment around evening, much to the relief of Pakistani HQ in Dhaka then captured the Medical college and Pravartak hill as well. Bengali troops fell back to Halishahar, while small groups continued to make hit and run attacks around the city. Bengali forces now held EPR HQ, Dampara, Kalurghat Radio station, Chawkbazar and Court hill, but were isolated from each other and had almost exhausted their ammunition. Major Zia kept bulk of his forces at Kalurghat, while small groups were sent to the city to make hit and run attacks. The initiative now fully rested with the Pakistan forces after 4 days of bitter fighting.
March 30
Brig. Ansari began organizing a task force to clear the city, while Brig. Shaffi took overall command with the task of taking out the Radio station, EPR HQ and the Dampara police line immediately. While Pakistan Navy and army shelled Bengali positions, Gen. Mitha again sent a commando platoon to attack Kalurghat Radio Station, which failed. 20 Baluch next attacked towards the station but was repulsed after heavy fighting. Finally the PAF bombed the station, and the transmitters were removed to another location by Bengali personnel. Sporadic clashed took place around the EPR HQ, while Major Zia left Maj. Shawkat in command at Kalurghat Bridge (1000+ Bengali troops were still positioned there) and left for Ramgarh around 7:30 PM to seek Indian assistance.
March 31
Brig. Ansari launched a battalion sized attack on the EPR HQ at Halishahar (a strongly fortified area), supported by another battalion and 2 tanks, with PNS Babur and Jahangir and 2 gunboats, plus a mortar battery lending fire support. The buildings at the HQ were leveled by shellfire - inadvertently leading to the death of Pakistani POWs. The battle raged from 7 am to 2 PM, and when the attack stalled around midday, PAF jets bombed the area, and another 3 hours were needed before the base was secured. Bengali survivors fled north through by lanes and left the city altogether.
Aftermath
Brig. Ansari next attacked the Dampara police line on March 31 with his task force which fell after a sharp firefight. On April 1 the Pakistani attack on Court hill was repulsed with the loss of a tank. Brig. Ansari launched an attack with 2 companies on April 2, which got stalled. He then sent 4 companies from two directions at Court hill, and captured the place, leaving Bengali troops with control of Chawlkbazar only in Chittagong city. For his services the superseded Brig. Ansari was awarded the Hilal-i-Jurat and the rank of Major General.
Between April 3 April 6, Pakistani troops carried out mop up operations and fought several sharp street battles in and around Chawlkbazar, and by April 10 they had secured the city. Captain Rafiq and Maj. Zia had secured aid from BSF by April 6, and were busy organizing Bengali forces around Ramgarh. Bengali troops had captured 18 Pakistani officers near Ramgarh including Lt. Col Sheikh and Major Iqbal, all of whom Maj. Zia surrendered to the Indian authorities. Major Shafiullah and Major Khaled Musharraf sent 1 company each to Ramgarh, while Maj. Zia was busy attending the meetings at Teliapara and was absent from Chitagong front. All Bengali troops had left the city to regroup in 2 areas, at Kalurghat (1,000+ Bengali troops of the EPR and EBR), and at Kumira to the north of the city. By the 10th of April, Pakistani troops were poised to launch a three pronged coordinated attack to drive the Bengali troops from their positions.
