Prafulyanalini Bramha (1914-1937) was born in Comilla of the undivided Bengal. A lawyer by profession, her father Rajanikanta Bramha abandoned his legal practice during the non-cooperation movement; the nationalist environment she was brought up in.
She became a member of the Yugantar as a student of the Faizunnisa Girls’ School, where she made small groups of girls and later merged them with Calcutta’s Chhatri Samgha (Girls’ Club). They took part clandestinely in revolver shooting and mastering other martial arts from Barun Bhattacharyya, a revolutionary. Prafulyanalini roped in Shanti Ghosh, who in turn brought in Suniti Hazra and pressed their leaders, Akhil Nandy, and Birendranath Bhattacharyya, to let them have bigger roles like the boys.
Finally, they agreed to involve them in the assassination plot of the district magistrate; but at the last leg excluded her in the organizational interest. On 14 December 1931, Shanti and Suniti, aged 14 and 15 years respectively, entered the bungalow of Magistrate Stevens with a pistol and shot him dead at point-blank range.
The next day, the police arrested Prafulyanalini but failed to establish her involvement in court. After a brief detention in Comilla, she was taken to the Hijli Camp, from where she passed the Intermediate and B A examinations. In 1936, she was brought back to Comilla and interned in her village, Kaksa. During her internment, she suffered from chronic appendicitis; but due to the persistent police refusal to take her to Calcutta for treatment; she died in Comilla on her 24th birthday (22 February 1937).
