Liberation of Bangladesh in the 1971 Indo Pak War was achieved in style with over 90,000 Pakistani soldiers surrendering: the largest since World War II. It also resulted in the liberation of East Pakistan and creation of an independent nation of Bangladesh. Officially the Indo Pak War of 1971 was fought from 3 to 16 December 1971.
Unofficially an intense battle was fought in Garibpur on 21 November; it marked the beginning of the end of Pakistan in East Pakistan. A Brief Commentary on the War in the Eastern Theatre by Lt Gen TS Shergil, PVSM, PhD, Chairman Military Literature Festival Society, Punjab. Operation Searchlight by Pakistan in East Pakistan was a cleansing of intellectuals that, set off animal instincts among the soldiers and those that supported Pakistan. This behaviour saw a backlash among the population and the Pakistan Army had to close into their defences and move out only with road opening parties; a ‘fortress mentality’ set in that opened a large area open to anti Pakistan irregulars; the ‘Mukti Bahini’ were not so deep into East Pakistan. Indian Army 2 Corps, 33 Corps and 4 Corps were slow to recognize the large gaps that existed between these ‘forts.’ 2 Corps and 33 Corps had been allotted the entire Inland Water Transport (IWT) resources of Eastern Command as IWT could not reach 4 Corps because the mountain ranges of Meghalaya and NC Hills obviated such a transfer and thus, 4 Corps was allotted MI 4 helicopters for a lift capacity of approximately two companies to cross major water obstacles. All Corps and 101 Communication Zone-that had no serious water obstacle on its thrust line- started operations in a conventional manner attacking hard defences and suffered serious casualties and reverses. It is only after establishing contacts with locals that realisation dawned that, the flanks were open.
A chance reconnaissance flight over River Meghna convinced Lt Gen Sagat Singh to use his air lift to bypass a large fortress on the river. After suffering losses against hard defences, Maj Gen Nakra commanding 101 Communication Zone, employing local guides, by passed those defences and moved on towards Dacca. The rest is history. Both 2 Corps and 33 Corps never used the IWT resources allotted to them however, 4 Corps used the heli lift resource to change history. Note: In counterinsurgency, wherever road opening parties are used it indicates that, the psychological war is failing or has failed, and troops are no longer in essential contact with the masses.
The United States turned a blind eye towards nearly 300,000 Bengalis killed by the Pakistan army in East Pakistan in the months preceding the India-Pakistan war in Dec 1971. This was because the US was using Pakistan as a conduit for a historic rapprochement with Communist China, a country it had no diplomatic ties with. Gary J. Bass author of ‘The Blood Telegram: Nixon, Kissinger and a forgotten genocide’ The Orbat India’s Eastern Command set the Pakistani communication centres as its objectives. •
