Besides Mukti Bahini, many other independent forces were organised that fought the Pakistan Army in various regions of Bangladesh and liberated many areas.
These Bahinis include:
One of the strongest and most effective local guerrilla groups was located in the Tangail area, where a young Bengali revolutionary named Abdul Kader Siddiqui, a dashing, flamboyant and fearless leader (later self-styled "General" and nick named "Bagha" or "Tiger" Kader) formed an effective band of insurgents. The strength of this group eventually grew to 16,000 armed men. It not only dominated the Tangail area, certain areas of Mymensingh District and Dhaka, but also played a crucial role in the Indian Army's plans for the liberation of Dhaka.
Liberation was brought by the common people.
Who was I - a mere student leader at a Mufassil college! I had war thrust upon me. Bangabandhu's 7th March speech inspired the nation, and it's true we were doing cadet-type training and mock drills. But I will not deny that we were in shock on March 26 1971. The tragedy stunned us.
When the [Mujibnagar] leaders left for India, the field was empty. I was a college student - I was not equipped to lead men in a war. You can call me a fool, but I thought that if I left, people would laugh at me. I remembered the fiery speeches I had made, and thought that I could never show my face again in Tangail if I turned tail. On March 26, I realised that it is easy to talk about giving blood in front of a microphone, but it is tough to do it on the battlefield.
'Tiger' Kader Siddiqui determination to fight back
Unlike other resistance movements in history, the Bengali resistance was never so terrorised as to resort to betrayal and treachery.
