East Pakistan Air Operations covers the activity of the
The Indian Air force aided the Mukti Bahini in organizing the formation of light aircraft (called Kilo flight). They were manned and serviced mainly by Bengali pilots and technicians who had defected from the Pakistani Air Force.[4]
This unit launched attacks on targets in Bangladesh on December 3, 1971, prior to the start of formal combat between India and Pakistan. The first of the engagements between the opposing air powers occurred before the formal declaration of hostilities. Indian Air units commenced operations on 4 December 1971 in the eastern theater. By 7 December 1971, Tejgaon airport was put out of operation thereby grounding the PAF in East Pakistan. Indian units and Kilo Flight continued flying missions over Bangladesh until the unconditional surrender of Pakistani forces to joint Bangladeshi and Indian forces command on 16 December 1971.
The Eastern Theater: Historical Background
In 1958, the Eastern operational group was formed in Kolkata, and it was upgraded into a Command the following year. Following the Sino-Indian War of 1962, the Eastern Air Command Headquarters shifted to Upper Shillong, and extensive efforts to increase its operational capabilities in terms of the number of squadrons and modernization of its warplanes and operational infrastructure began, as the added emphasis was given to countering any possible Chinese threat. In contrast, Dhaka airfield at Tezgaon was activated only in 1949, and a squadron of
1965 Indo-Pakistani War: Eastern Theater
The air forces of both countries launched attacks against each other's bases in the eastern theater as soon as hostilities commenced in September 1965. The IAF bombed airfields and airstrips located in East Pakistan (at

Operation Great Fly-In
Pakistan Eastern Command had planned an operation named "Blitz" in February 1971 to counter the Bengali political movement, and the 13th Frontier Force and 22nd Baluch battalions had arrived in East Pakistan from Karachi[18][15] between 27 February and 1 March 1971, via PIA aircraft, before the Pakistani Air Force took over Tejgaon Airport administration[19] as part of the newly planned operation. After the decision to launch Operation Searchlight was made, the Pakistan High Command decided to reinforce the 14th Infantry Division in East Pakistan with the 9th and 16th Infantry Divisions after the start of the operation. These divisions began preparing for the move after 22 February 1971, and military personnel began arriving in East Pakistan via PIA and Air Force planes. Because India had banned overflights starting 20 January 1971, all Pakistani planes had to detour to Sri Lanka during trips between East and West Pakistan.
Pakistan Air Force No. 6 Squadron had nine Hercules
Between 25 March and 6 April 1971, two Division Headquarters (9th and 16th), with the five Brigade Headquarters, (the 205th, 27th, 34th, 313th and 117th Brigades), along with one commando and twelve infantry battalions were moved to East Pakistan through the air.[22] Between 24 April and 2 May another three infantry battalions, along with two heavy mortar batteries, two wings each of East Pakistan Civil Armed Force and West Pakistan Rangers, and a number of North West Frontier Scouts, were re-positioned as well.[22] After 25 March, two C-130B planes were stationed in Dhaka to link the areas under Pakistani control in East Pakistan with Dhaka and also ferry fuel from Sri Lank and Myanmar.
PAF Operations during Operation Searchlight
Air Commodore Mitty Masud had opposed Operation Searchlight on moral grounds in a meeting of Pakistani Senior officers on 15 March[23] and then had refused requests from Army to commence airstrikes on 29 March.[24][25] He also assured Bengali PAF staff of their personal safety on 27 March and on 30 March gave them the option of declining missions or going on leave but also warned them to refrain from treason.[24][25]
After 26 March, Pakistani Army was initially confined to a handful of bases across the province, with control over Airports near

PAF airstrikes and 313th Brigade attacks had driven Bengali soldiers from their positions at Khadimnagar, and as they reformed at Haripur, PAF sorties on 20 April caused them to retreat across the border. Chandpur fell to river borne troops after Sabres bombed Bengali positions near the city on 20 April. After Mukti Bahini Sector 1 and Sector 2 troops repulsed 20 Baloch and 24 FF attacks on Belonia, a small strip of land surrounded on three sides by Indian territory, PAF Sabres, which had refrained from hitting Bengali positions fearing violations on Indian airspace, launched strikes while Army Aviation heli-dropped commandoes at night behind Bengali positions on 17 June, and again on 19 June, forcing Mukti Bahini across the border.[51][52] With the Fall of Belonia, Mukti Bahini control shrunk to a few border enclaves and they shifted to waging guerrilla warfare against the occupying forces.[51]
The PAF had enjoyed total air supremacy during March – October as the Mukti Bahini lacked both planes and air defense capability to counter their efforts, and flew 100 to 170 sorties
Mukti Bahini Airforce/ Bangladesh Air force : Kilo Flight
The Indian Army had been helping the Mukti Bahini, through Operation Jackpot, since May 1971, while the Indian Navy had helped set up the Bengali Naval commando unit and had provided command staff for the Bengali gunboats, which were busy mining riverine craft and harassing merchant marine operations in East Pakistan. The IAF had flown reconnaissance flights over East Pakistan since June 1971, but could not come to grips with the PAF until formal hostilities commenced. Nine Bengali pilots (Three former PAF and six civilian pilots) and fifty technicians - formerly of the PAF and serving with the Mukti Bahini in various capacities - were gathered for a special mission on 28 September 1971 at Dimapur in Nagaland.[55]

The helicopter was rigged to fire 14 rockets from pylons attached to its side and had .303 Browning machine guns installed, in addition to having 1-inch (25 mm) steel plate welded to its floor for extra protection. Squadron Leader Sultan Mahmood, Flight Lieutenant Bodiul Alam, and Captain Shahabuddin, all of whom later won the Bir Uttam award, operated the helicopter. The Otter boasted 7 rockets under each of its wings and could deliver ten 25 pound bombs, which were rolled out of the aircraft by hand through a makeshift door. Flight Lt. Shamsul Alam, along with Captains Akram Ahmed and Sharfuddin Ahmad, flew the Otter - all three were later awarded Bir Uttam for their service in 1971. This tiny force was dubbed Kilo Flight, the first fighting formation of the nascent Bangladesh Air force.[56]<refMohan & Chopra 2013, p. 49</ref>

Pakistan high command was fully aware that the IAF considerably outnumbered the PAF eastern detachment (161 serviceable aircraft to 16 aircraft in December 1971),
Pakistan deployed no additional air defense assets other than one light antiaircraft "Ack-Ack" regiment and a few additional batteries to assist the PAF in 1971. The 6th Light Ack-Ack guarded Dhaka,
The undeclared war: November 1971
After August 1971, Mukti Bahini began to launch conventional attacks along the border areas, while groups of guerrillas and naval commandos stepped up their activities. By November end, Pakistan forces had lost control of 5,000 square kilometres (1,900 sq mi) of territories to Mukti Bahini. PAF flew 100 sorties in support of the ground forces between October and 3 December, including bombing of Belonia on 7 and 10 November before Mukti Bahini occupied the area,[71][72] flew several ground attack sorties near Garibpur on 19, 21 November and 22, leading to the over the Salient of Boyra in West Bengal on 22 November, and on Indian troops near Akhuara on 2 December 1971.[73][74] Pakistan had lost 2 planes on 22 November over Boyra, and as no replacement aircraft had been sent from West Pakistan, were down to 14 operational jets by December 1971.
The War Begins: first air strike in Bangladesh

4 December
PAF lost two Sabres in dog fights over Dhaka - to IAF Hunters striking Kurmitola. Wing Commander S. M. Ahmed and Flight Lt. Saeed ejected safely over the village of Ghazipur, but were not found by search parties. They were listed as "missing" for the duration of the war and then assumed killed by a hostile local populace.[citation needed] Wing Commander Nadrinder Chatrath of No 17 Squadron and Flight Officer Harish Masand each are credited with a Sabre kill. Squadron Leader K.D. Mehra of IAF No. 14 squadron was shot down by a Sabre. Later in the day PAF Flight officer Sajjad Noor was shot down by IAF NO 14 Squadron Leader Sundaresan, who lost his wingman when PAF Squadron Leader Dilawar Hussain shot down the Hunter of Flight Lt K. C. Tremenhere during the same dogfight. Flight Lt. K. C. Tremenhere and Sajjad Noor ejected safely, and both were rescued and Tremenhere became a POW.[77]
PAF had flown Thirty two operational sorties against IAF incursions on 4 December, expending 30,000 rounds of ammunition, while the ground-based weapons had fired 70,000 rounds on the same day, the highest expenditure per day per aircraft of ammunition in the history of the PAF. Pakistani authorities claimed between 10 and 12 IAF planes were destroyed, and took measures to conserve ammunition in anticipation of a long war.[75] IAF claimed five Sabres shot down and another three destroyed on the ground. India's only aircraft carrier INS Vikrant (with its Sea Hawk fighter bombers and Breguet Alize ASW aircraft) mounted attacks against the civilian airport at Cox's Bazar and Chittagong Harbor.
In addition to attacking Tezgaon, Chattagong, Jessore and Ishwardi airfields, IAF attacked several other targets, including the Teesta Bridge, Chandpur and Goalanda Ferry Ghats and flew several ground support missions. The IAF lost six Hunters (two in air combat) and one Su-7 shot down during the day. Two Hunters of No. 7 Squadron were shot down by ack ack fire while hitting an ammunition train at Lal Munir Hat, one pilot was KIA. One of the pilots of the stricken planes, Squadron Leader S. K. Gupta, safely ejected at Bagdogra.[78] Squadron Leader K. D. Mehra's Hunter was shot down by ack ack[78] he managed to evade capture and get back to Indian territory. Two Hunters of IAF No. 37 Squadron was shot down over Tezgaon and two pilots - Squadron Leader S. B. Samanta and Fg. Officer S. G. Khonde was killed.[78] One No. 221 Squadron l Su-7 was shot down with the pilot, Squadron Leader V. Bhutani taken POW.[78] The mission to knock PAF off the air had failed and no significant damage was done to the PAF assets in well-dispersed and camouflaged locations. While The PAF did not oppose all IAF incursions over Dhaka, choosing to fight when odds were even, it had forcing many IAF missions to abort. The PAF was not able to intercept any IAF missions outside Dhaka. IAF Eastern Command sent No. 30 squadron and other assets to the Western Front, realizing PAF posed little threat to IAF bases in the east.
5 December
Canberra bombers bombed Tejgaon and Kurmitola at night. The IAF switched tactics, ground support and attacks on Pakistani targets continued, including the first use of Napalm in combat by IAF near Jessore, but having lost 5 aircraft over Dhaka, attacks on Tejgaon were scaled back. IAF Squadron No. 37, No. 17, No. 221 and No. 22 flew sorties towards Tejgaon to lure PAF Sabres into dog fights outside Dhaka without success. The lessening pressure led to the PAF flying some ground support missions over Comilla and other areas. In total 20 operational sorties were flown by the Sabres, and 12,000 rounds of ammunition were used up during 5 December by the PAF.[79] By the evening of 5 December, the IAF realized that a change of tactics was necessary. The ack-ack regiment at Tejgaon had managed to successfully defend the airbase during 5 December and the night of the early hours of the 6th against all Indian attacks. The United Nations had requested a ceasefire of the Air Campaign over Dhaka to take place between 10:30 AM and 12:30 PM, so a C-130 could evacuate foreign civilians from Dhaka, and both the Pakistan and Indian governments had agreed to the request.[80]
6 December: PAF grounded
Early in the morning of 6 December a sortie by four PAF Sabres intercepted four Hunters of IAF No. 17 squadron without any dogfights near
Pakistan Air force and army engineers estimated that it would need 8 hours of continuous effort to repair the runway. Helped by civilian workers, worked uninterrupted around the clock during the night of 6th and early hours of 7 December, and by 4:50 AM 7 December, three bomb craters were filled up and the runway was ready for flying operations.[68][84] The IAF had launched no night raids in East Pakistan on 6 December. Pakistan Army 314th brigade (CO: Col. Fazle Hamid) used road and river transports to retreat to Dhaka at night due to the daytime dominance of IAF.[68]
7 December
PAF pilots were waiting for the dawn to get their Sabres airborne when a single Mig-21 bombed and cratered the Tejgaon runway again. Kurmitola was to remain operational until the morning of 7 December, when Mig-21s of No. 28 Squadron again hit that runway. IAF squadrons repeatedly attacked Tejgaon, and No. 14 Squadron attacked Barisal airfield. With the Sabres grounded, IAF No. 7 Squadron was pulled out of the eastern operations on 6 December to help the army in the west. A Hunter from No. 14 Squadron was shot down by anti-aircraft fire during the day. INS Vikrant, the Navy's sole aircraft carrier at the time, sent Sea Hawks to bomb Chittagong harbor, Cox's Bazar, and Barisal. PAF engineers now estimated that 36 hours of work without further damage was needed to make Tejgaon AFB operational again. The IAF attacked Tejgaon repeatedly for the duration of the war to prevent any required repairs to the runway. In desperation, it was suggested that the broad streets at second capital be used as runways, but technical problems ruled out that possibility, effectively grounding the PAF Sabres in East Pakistan for the duration.[68]
Pakistan air operations until 16 December 1971
6th Light Ack-Ack regiment (CO: Lt. Col. Muhammad Afzal) became the only defense of Tejgaon AFB after the runway was cratered on 7 December. Daily IAF bombing raids kept the Pakistan forces from making the necessary repairs for the remainder of the war. Four Caribouss from IAF No. 33 Squadron bombed Tejgaon on the early hours of 8 December followed by Mig -21s.[85] However, PAF and Army aviation helicopters continued flying daily night missions to Pakistan army positions at Bogra, Comilla, Maulivabazar, Khulna and other bases carrying reinforcements, supplies, munitions and evacuating the wounded.

Kilo Flight missions
After their initial mission, Kilo Flight moved from Kailashahar to Agartala to cut down fuel usage and turn around time after 4 December 1971, and used Shamshernagar as a forward base.
Indian troops made a heliborne infantry assault by two companies in about nine Mil Mi-4s, escorted by "gunship" Alouttes on 7 December near Sylhet.
IAF Activity until 16 December 1971
IAF focus shifted on supporting the Mitro Bahini advance following the grounding of PAF after 7 December 1971.
Anti shipping missions struck ships and ferries, while ferry ghats, bridges, army positions, troop convoys and ports were also bombed. Ferries across major river crossings were sunk by the IAF, thus denying the Pakistani army its line of retreat to Dhaka. Tejgaon was daily bombed to keep the PAF from repairing the runway
Tangail Para Drop
The
MiGs attack Governor House
On the morning of 14 December, a message was intercepted by Indian Intelligence concerning a high-level meeting of the civilian administration in East Pakistan. A decision was then made to mount an attack. Within 15 minutes of the interception of the message, a strike was launched against Dhaka. Armed with tourist guide maps of the city, four
Pakistan Forces General Headquarters had declined to provide a substantial naval contingent for the defense of East Pakistan, for two reasons. First, they had an inadequate number of ships to challenge the Indian navy on both fronts. Second, the PAF in the east was not deemed strong enough to protect the ships from Indian airpower (i.e. both the IAF and the Indian Navy air arm). Pakistan Eastern Command had planned to fight the war without the Navy, and faced with a hopeless task against overwhelming odds, the Navy planned to remain in port when war broke out.[102] The fate of Pakistani naval vessels in December was ample proof of the soundness of this decision, and the repercussions of neglecting East Pakistan defense infrastructure, which was the reason the PAF could only station 1 squadron of planes there.[69] The Pakistan Navy had 4 Gunboats (PNS Jessore, PNS Rajshahi, PNS Comilla, and PNS Sylhet). All were 345 ton vessels, capable of attaining a maximum speed of 20 knots, crewed by 29 sailors, and fitted with 40/60 mm. cannons and machine guns, in East Pakistan. One patrol boat (PNS Balaghat) and 17 armed boats (armed with 12.7mm./20mm. guns and/or .50 or .303 Browning machine guns), in addition to numerous civilian-owned boats requisitioned and armed with various weapons by Pakistani forces, were also part of the Pakistani naval contingent.[103] The improvised armed boats were adequate for patrolling and anti-insurgency operations, but hopelessly out of place in conventional warfare. Before the start of hostilities in December, PNS Jessore was in Khulna with 4 other boats, PNS Rajshahi, PNS Comilla, and PNS Balaghat were at Chittagong, and PNS Sylhet was undergoing repairs at a dry-dock near Dhaka. The outbreak of hostilities on 3 December found most of these boats scattered around the province.[75]
Indian aircraft attacked the Rajshahi and Comilla near Chittagong on 4 December, with the Rajshahi damaged and the Comilla sunk.[102] The Balaghat, which was not attacked, rescued the Comilla crew and returned to Chittagong with the surviving ships. On 5 December, Indian planes sank two patrol boats in Khulna. The PNS Sylhet was destroyed on 6 December and the Balaghat on 9 December by Indian aircraft.
The 39th Division (under General Rahim Khan) Headquarters at Chandpur had requested evacuation by river on 8 December. Under the escort of a gunboat, the flotilla, made up of local launches, sailed in the early hours of 10 December. The IAF spotted and bombed the ships, and PNS Jessore, which had withdrawn from Khulna to Dacca, was destroyed escorting boats evacuating Pakistani troops from Chandpur while other boats were either sunk or beached themselves and failed to reach Dhaka.[104] The survivors later were evacuated by ships and helicopters operating at night. PNS Rajshahi was repaired, and under the command of Lt. Commander Sikander Hayat, managed to evade the Indian blockade and reach Malaysia before the surrender on 16 December. From there, it sailed to Karachi and continued to serve in the Pakistan navy.
Blue on blue: Tragedy near Khulna
Indian Army Eastern Command had ordered Bangladesh Navy gunboats BNS Palash (CO: Lieutenant A.K. Mitra, Indian Navy) and BNS Padma (CO: Lt. Commander Joyanta Kumar Roy Chowdhury, Indian Navy), accompanied by INS Panvel (CO: Lt. Commander J. P. A. Noronha, Indian Navy) and under the overall command of Commander M. N. Samant of Indian Navy, to sail to the port at Mongla in an anti shipping mission.[105][106] The Bangladesh Navy ships flew the national ensign, carried Bengali seamen and Indian command crews, and they had been operating against Pakistani shipping since November, and under the advice of Indian Eastern Air command, had painted their superstructure yellow to avoid misidentification and fixed 15 feet by 10 feet yellow cloths on their bridges to identify them as friendly crafts to the IAF. This had been reported back to Eastern Air Command.[107] This task force ("Alpha Force"), accompanied by BST craft Chitrangada sailed from Hasnabad on 6 December, entered Mangla at 7:30 AM on 10 December, and took over the abandoned port facility. Commander Samant then decided to sail towards Khulna, which was 20 miles east of Dum Dum airport, lay north of the bomb line and a designated target of IAF planes. This was not part of the mission but Commander Samant decided to push on anyway, leaving Chitrangada at Mongla.
The flotilla sailed along the Passur river was closing on Khulna dockyard by 11:45 AM, Panvel in the lead, followed by and Palash when three
The Indian Navy gave 13 awards (including 3 Mahavir Chakras and 5 Vir Chakras) to the Indian rank-and-file involved in this incident.[109] Bengali Seaman Ruhul Amin, who tried to save BNS Palash despite being wounded and ordered to abandon ship, and who later died under torture after being taken captive, was awarded the Bir Shreshtro medal by the Bangladeshi government.
Aftermath
Pakistani authorities claimed that between 4–15 December the IAF lost 22 to 24 aircraft (7 to the PAF and the rest to ack-ack units).[68] The IAF records 19 aircraft lost in East Pakistan, 3 in air combat, 6 to accidents and the rest to ack-ack, while 5 Sabres were shot down by IAF planes.[82] Pakistan Armed Forces Headquarters had issued orders to blow up all remaining the aircraft, but Air Commodore Inamul Haque Khan had pointed out that the sight of burning planes would demoralize the Pa kistani troops defending Dacca.[7] Therefore, PAF personnel destroyed the ammunition stocks and sabotaged the electric and hydraulic systems of the aircraft on 15 December.
Tezgaon airport was made operational by 25 December 1971 through the joint efforts of Indian and Pakistani airmen and engineers and Bengali workers. Kilo flight relocated to Tezgaon during that period. The newly formed Bangladesh Air Force lacked trained personnel and for some time the base was administered by IAF Air Commodore Kingly. Bangladesh government awarded six

The Hiller was taken over by Bangladesh Army, while Bengali airmen set to work on fixing the aircraft. By March 1972, eight Sabers,[114] one T-33 and the Alouette was airworthy. Five Sabers, the lone T-33 and the Alouette were activated for service. On 26 March 1972, to mark the first anniversary of Independence day, Bangladesh Air Force staged a fly past with 2 F-86 Sabre, OneT-33, 3 Alouette and one DHC-3 Otter.[115][116] These aircraft remained operational until replaced by more modern aircraft after 1973.
Importance of Air Power during Bangladesh Liberation War
After the beginning of Operation Searchlight, PAF jets flew sorties against Mukti Bahini positions to aid the Pakistan Army, and helicopters ferried reinforcements and supplies to remote Army bases surrounded by Mukti Bahini, evacuated wounded from isolated bases, acted as artillery spotters, flew reconnaissance missions over hostile territory, and air-dropped combat troops off in remote places to outflank and cutoff Mukti Bahini positions.[76] This proved critical to the initial survival and ultimate success of the Pakistani troops during the early phases of the operation.[117][28]
Deciding factors of the East Pakistan defense plan
The Pakistan army 1971 military strategy depended on winning an overwhelming, decisive victory over Indian forces in the Western Front, while the contingent in occupied Bangladesh needed only to hold out until the issue was decided in the West.
- Deploying all available forces to defend the Dhaka Bowl along the Meghna, Jamuna and Padma Rivers. The Pakistan Army could use interior lines to switch forces as needed, and build up a strategic reserve while fighting on a narrower front. The disadvantage was that large tracts of areas outside the bowl would be lost without much effort from the invaders; India could set up the Bangladesh government easily inside the province. Also, it gave the Indians the opportunity to divert some of their forces to the west (thus threatening the balance of forces there) where a near-parity in forces was needed for a decisive result.
- Fortress Deployment: Fortify and provision certain cities along expected Indian lines of advance, deploy troops along the border, then make a fighting withdrawal to the fortresses and hold out until Pakistan achieved victory in the west. This meant surrendering the initiative to the enemy, and being cutoff without mutual support, giving the Indians the choice to bypass and contain some fortresses and concentrate on others. This concept had two advantages: it did not call for the voluntary surrender of territory, concentrated forces and required limited mobility. Also, there was a chance the fortresses might tie up a large number of Indian forces and they might not have sufficient forces to threaten the Dhaka Bowl if they bypassed the fortresses.
The other two options called for a more flexible, mobile defense of the province.
- Deploy troops in depth near the border then conduct a fighting withdrawal towards the Dhaka Bowl, and hold out until a decision is reached in the Western Front.
- Positional Defense: Use mobility to parry initial Indian thrusts then redeploy forces to take advantage of any opportunity for counterattack or fall back to defensive position. This was considered the best option given the geographic feature of Bangladesh. Also, a large uncommitted reserve force was needed to execute this strategy properly; the Eastern Command had no such reserves, and could not create one unless reinforced by West Pakistan or by abandoning the "defending every inch of the province" concept.
However, Pakistan Command did not adopt the flexible defense strategy because of the following factors:
- Nearly all roads led to Dhaka, there were few lateral roads. Wide rivers and, during the April–October monsoon, 300 other water channels were a formidable challenge to the movement of troops and supplies. Air and river control were necessary for unhindered movement along interior lines.C-130 planes (which had played a crucial role during Operation Searchlight) were withdrawn from the province,[citation needed] diminishing the airlift capacity of the Pakistani forces further. The Mukti Bahini had sabotaged 231 bridges and 122 rail lines[123] by November 1971 (thus diminishing transport capacity to 10 percent of normal), and complicated the delivery of the daily minimum 600 tons of supplies to the army units.[124] Mukti Bahini Naval commandos had managed to sink or damage 126 ships/coasters/ferries during that same time span, while one source confirms at least 65 vessels of various types (15 Pakistani ships, 11 coasters, 7 gunboats, 11 barges, 2 tankers and 19 river craft by November 1971).[125] had been sunk between August–November 1971. At least 100,000 tons of shipping was sunk or crippled, jetties and wharves were disabled and channels blocked, and the commandos kept East Pakistan in a state of siege without having a single vessel[126]The operational capability of Pakistan Navy was reduced as a result of Operation Jackpot.
Mobility of Pakistan forces were hampered due to the above factors, and they also feared being ambushed by Mukti Bahini if they moved at night. Pakistani planners expected the PAF to last 24 hours in the east, so IAF dominance would pose considerable threat to Pakistan troop convoys and can unhinge any strategy depended on mobility. The fortress concept was adopted; the planners decided on a single defensive deployment of troops on the border, which went against the troop deployments advocated by earlier plans. This was done to stick to the GHQ order of not surrendering any territory to the Mukti Bahini. When devising troop deployments, the planners mixed political considerations with strategic ones and envisioned a forward-leaning defence in depth:[127][128][129][130]
