East Pakistan Bengali Patriotic song from the 1971 India-Pakistan war (Bangladesh war)

This song was made in East Pakistan (now Bangladesh) by Radio Pakistan Dhaka. The song is in local bangladeshi language and is in support of Pakistan army.
Before 1971, Pakistan consisted of 2 territories seperated by 2,000, the western territory was called West Pakistan (where the capital was located) and the eastern territory was called East Pakistan (now Bangladesh). In early 1970, local rebellions had sprung up which aimed to liberate East Pakistan (now Bangladesh) from West Pakistan (mainland Pakistan). Taking advantage of the rebellions, India launched an invasion of East Pakistan to support the rebels. Pakistan army was completely surrounded and cutt off from the mainland as the Indian navy blockaded the ports (the only way to access mainland Pakistan), also the Pakistan airforce could not help in this war as there was no way for it to reach East Pakistan as it was too far away. As things had gone to a point of no return, the Pakistan army in East Pakistan surrendered. 90,000 soldiers, civil servants and government employees surrendered and Bangladesh was made.

I found this song in an archive, I don’t understand it, but I really like the melody and the voice of the singer, that’s why i’m sharing it. It’s surprising how things turn out sometimes… the bengali singers of this song would never have thought that East Pakistan would soon become a seperate country. The singers would probably have died by now, but I am still not sharing their names, as in Bangladesh, it’s not considered good to be pro-Pakistani.
