Usha Mukherjee(1915/16- ?), daughter of Guruprasanna Mukherjee belonged to Baherak village of Dhaka, and was born in Comilla. Her elder brother, Amulya Mukherjee was a leading revolutionary of the Anushilan Samiti. Hence, they had an early exposure to the revolutionary life and their terrorization by the police.
Usha and her sister Parul both joined the Anushilan Samiti at a very early age; with Usha marked by her dare-devilry and skill in physical exercise with lathi and knife. In 1934, Usha was taken into custody as a political prisoner and kept in the Hijli Jail for three years; while Parul was already interned in her home in 1932. Next year, when the police issued a warrant against Parul for her alleged involvement in the inter-provincial conspiracy case, she absconded. As an underground worker, she had a hectic life hopping the Anushilan Samiti units from Rangpur to Barishal-Khulna.
Ahushilan Samiti at the time had a hideout in Titagarh, where they stored explosives and made bombs. To camouflage it as a family residence, the leaders brought Parul to that place. In an early morning swoop (20 January 1935), police arrested Parul, Purnananda Dasgupta, and Shyamabinod Pal along with a revolver, explosives, and papers with bomb-making formulae. Left in custody for the trial under Titagarh Conspiracy Case, Parul was sentenced in 1937 to three years of rigorous imprisonment and was lodged in the Presidency Jail in Calcutta.
