Kalpana Datta

Kalpana Datta was born on July 27, 1913, in the village of Sreepur in Chittagong district, then part of Bengal under the British Raj and now in Bangladesh ^[1]. Her family belonged to the educated Bengali middle class; her grandfather had received official recognition for social service, and the household valued schooling for daughters at a time when that was far from universal.

She completed her matriculation from Chittagong in 1929 and moved to Calcutta, enrolling at Bethune College to study science ^[1]. Calcutta in those years was thick with nationalist argument, and the young student was drawn quickly into it. She joined the Chhatri Sangha, a semi-revolutionary association of women students that counted Bina Das and Pritilata Waddedar among its members and served as a recruiting ground for the armed underground ^[2].

Stories of revolutionary heroism circulated widely among Bengali students of her generation. Kalpana later recalled that accounts of Kshudiram Bose and the Chittagong rebels shaped her thinking long before she handled a weapon. When news of the Chittagong armoury raid of April 1930 reached Calcutta, the eighteen raiders who died at Jalalabad hill became, for her and many contemporaries, an urgent summons rather than a distant headline ^[3].

In May 1931 Kalpana Datta returned to Chittagong and sought contact with the survivors of Surya Sen's Indian Republican Army, the group that had seized the police and auxiliary armouries the previous year ^[3]. Through Purnendu Dastidar she was inducted into the organisation, one of the first women admitted to its inner work alongside Pritilata Waddedar. The leadership initially confined women to courier and shelter duties, but Kalpana pressed for a direct role.

Her scientific training proved useful. She smuggled materials for explosives, learned to prepare gun cotton, and carried messages and arms between hideouts while the police hunted the remaining raiders across the district ^[2]. The group planned to blow up the walls of the Chittagong jail to free imprisoned comrades and to attack the special tribunal trying members of the movement. Kalpana took part in the reconnaissance for these operations, moving around the town dressed as a man to avoid notice.

A week before the planned attack on the European Club at Pahartali in September 1932, she was arrested while surveying the area in male disguise ^[1]. Released on bail for want of evidence, she went underground rather than await trial. The Pahartali attack proceeded without her under Pritilata Waddedar, who died during the action, leaving Kalpana the most prominent woman still active in the organisation ^[3].

For months Kalpana Datta lived as a fugitive, sheltering with Surya Sen and a shrinking band of associates in the villages around Chittagong. In February 1933 the police, acting on information, surrounded the house at Gairala where Sen was hiding; he was captured, though Kalpana and Kalikinkar Dey escaped after an exchange of fire ^[3]. Her freedom lasted three more months. On May 19, 1933, police encircled a hideout at Gahira; the revolutionary Tarakeswar Dastidar's associate Manindra Dutta was killed in the fighting, and Kalpana was taken alive ^[1].

She stood trial alongside Surya Sen and Tarakeswar Dastidar in the second supplementary case connected with the armoury raid. In 1934 the tribunal sentenced Sen and Dastidar to death; both were hanged in January that year. Kalpana, not yet twenty-one, received transportation for life, a sentence widely attributed in part to her youth ^[2].

Her imprisonment became a public cause. Rabindranath Tagore and Mahatma Gandhi were among those who pressed for the release of Bengal's detained revolutionaries, and in 1939, after roughly six years in jail, Kalpana Datta was freed ^[1]. She resumed her interrupted education and graduated from Calcutta University in 1940, closing one chapter of her political life as another opened ^[2].

Like many former revolutionaries of her generation, Kalpana Datta concluded in prison that individual armed action could not by itself dislodge the Raj. In 1940 she joined the Communist Party of India, turning from conspiracy to mass organisation ^[1]. The famine that devastated Bengal in 1943 gave her new work: she organised relief in Chittagong, ran kitchens, and helped rehabilitate destitute women, activity that contemporaries remembered as tireless and unglamorous ^[2].

In 1943 she married Puran Chand Joshi, then general secretary of the Communist Party of India, and thereafter was often known as Kalpana Joshi ^[1]. The marriage joined two of the most recognisable figures on the Indian left. In 1946 the party fielded her as its candidate from Chittagong in the Bengal Legislative Assembly election. She lost, but the campaign of a convicted armoury raid prisoner standing openly for office measured how much the political ground had shifted in a decade ^[2].

During this period she also set down her account of the movement that had defined her youth. Chittagong Armoury Raiders: Reminiscences, published in 1945 with a foreword by P. C. Joshi, remains one of the few insider narratives of Surya Sen's organisation and is still cited by historians of the uprising ^[4].

After Indian independence in 1947, Kalpana Datta gradually withdrew from front-line party politics, though she never renounced her convictions. The partition of Bengal placed her birthplace in East Pakistan, later Bangladesh, and like many Chittagong revolutionaries she lived the rest of her life on the Indian side of the border, chiefly in Calcutta and Delhi ^[1].

She took salaried work to support her family, serving for many years at the Indian Statistical Institute in Calcutta ^[2]. Her two sons grew up in a household where the armoury raid was family memory rather than legend; the elder, Chand Joshi, became a well-known journalist with the Hindustan Times ^[5]. P. C. Joshi, removed from the party leadership in 1948 and long at odds with its later line, died in 1980.

Recognition arrived slowly and from across a border. In 1992 the Government of Bangladesh honoured her for her part in the freedom struggle waged from Chittagong soil, one of several tributes she received late in life ^[2]. Kalpana Datta died in Delhi on February 8, 1995, at the age of eighty-one ^[1].

Any assessment of Kalpana Datta's achievements begins with what she represented: proof that the armed nationalist underground of Bengal was not an exclusively male affair. Together with Pritilata Waddedar, she forced open a movement that had hesitated to arm women, and her life sentence at twenty made her a household name across Bengal ^[2]. Historians of the Chittagong uprising, notably Manini Chatterjee in her study Do and Die, treat Datta's testimony and memoir as essential evidence for reconstructing the movement's inner life ^[3].

Her later career complicates the simple portrait of a teenage rebel. The shift from revolutionary terrorism to communist mass politics, famine relief, electoral contest, and finally quiet institutional work traces a path many Bengal revolutionaries followed, and her writing helped explain that evolution to later generations ^[4].

Popular culture has kept her memory in circulation. The 2010 Hindi film Khelein Hum Jee Jaan Sey, based on Chatterjee's book, portrayed the Chittagong uprising with Deepika Padukone in the role of Kalpana Datta, introducing her story to audiences far removed from the events of the 1930s ^[6]. For readers asking who was Kalpana Datta, the answer holds together an unusual span: student, bomb-maker, prisoner, party worker, author, and witness, all in one durable life. That range is why a Kalpana Datta biography still repays attention a century after her birth.
