I am sure when the Major General was punished, Indian army would have done an internal investigation into any looting by the rank and file and given punishment accordingly. We did not hide the fact, as there was no official sanction. Indian army as you have detailed subsequently acted very professionally.
We may have deviated from the thread:
I was referring to individual looting or unauthorized acquisitions that did happen. Our Bangladeshi guests here are referring to authorized removal of West Pakistani military assets. An anti-tank gun is far more important than a Sony transistor set. I will let them explain how significant that was. We know that a BD military delegation subsequently visited India in 1972, to discuss return of captured West Pakistani war materiel. It is unclear what the Indian army would have done with most of those assets, even if they had taken them to India. Pakistani and Indian ammunition for example was dissimilar
The Indian Armed Forces acted professionally only as far as West Pakistani civilians and armed forces personnel were concerned according to the Geneva Convention and the Rules of War. There
was fraternization, which was the first cause of friction between Bangladesh and India. Even the "Stranded Pakistanis " of the labor class were escorted safely to refugee camps under the ICRC. The Geneva and Mirpur camps are an Indian Army legacy.
It is often forgotten that India inserted itself in a civil war. The Indian campaign was not a recapture of its own territory such as the Soviet recapture of Stalingrad. The then East Pakistan was a constituent territory of Pakistan, with a significant number of bureaucrats, engineers of public works, and all manner of civil servants of West Pakistani origin who has been living in East Pakistan for at least two decades. They had settled homes, wives, school going children . These were middle and upper middle class families and at that time Pakistan was ahead of India in consumerism and with a healthy economy was able to import most appliances, and consumer durables that for India was lower on the priority list. These homes were as fully stocked as any upper class home in South Delhi today. When a family suddenly becomes an alien in the land they will do anything to save their lives and escape. A Toshiba TV or a Volkswagon Beetle left behind is of little consequence. The closest parallel is when Idi Amin of Uganda expelled hundreds of thousands of Gujarati Hindu citizens who were suddenly rendered homeless. There was no civil war or loss of life in Uganda but massive looting and capture of the homes.
Fraternizing with enemy civilians is against the Rules of War which the Indian Army did
not follow. Though this worked well for the 45,000 civilians leaving East Pakistan. They left along with the Indian Army to intenment camps in West Bengal and were interned under adequate conditions before being repatriated to Pakistan by air, or by special trains to Wagah. They carried their possessions of value with them to Pakistan.
It is a grey area if the Indian Army was professional or not because it did violate the non-fraternization rule.
On cars:
Looted or "gifted" cars could easily be identified in India at that time where the IA staff cars were all Ambassadors. It was much harder to detect a Sony Cassette Tape Deck in a jawan's home in Pauri Garhwal.
