After a few days, the police traced some of the revolutionaries. They were surrounded by several thousand troops while they took shelter in Jalalabad hills near Chittagong Cantonment on the afternoon of 22 April 1930. Over 80 troops and 12 revolutionaries were killed in the ensuing gunfight in the Battle of Jalalabad Hills. Sen dispersed his men to neighbouring villages in small groups and thus some escaped. A few fled to
Calcutta while some were arrested. An intense crackdown on the resistance ensued. Ananta Singh gave himself up in Calcutta coming away from his hiding place in
Chandannagar, to be close to the young teenagers captured and under trial in Chittagong. A few months later, Police Commissioner
Charles Tegart surrounded their hideout and, in the ensuing exchange of fire,
Jiban Ghoshal was killed. Some of the revolutionaries managed to reorganise. On 24 September 1932, Debi Prasad Gupta, Monoranjan Sen, Rajat Sen, Swadesh Roy, Phanindra Nandi and Subodh Chaudhary led by Pritilata Waddedar, attacked the Pahartali European Club, killing one woman and injuring several police officials. However, the plan was not entirely successful. The revolutionaries fled after the attack, but Pritilata, who got wounded, consumed cyanide to evade arrest and killed herself. The police searched the rest of the absconders. In Kalarpole encounter
Deba Gupta,
Monoranjan Sen,
Rajat Sen and Swadeshranjan Ray were killed while the other two, Subodh and Phani, were wounded and arrested. During 1930–1932, 22 officials and 220 others were killed by revolutionaries in separate incidents. Debi Prasad Gupta's brother was sentenced to transportation for life.
The armoury raid trial The mass trial of those arrested during and after the raids concluded in January 1932 and the judgement was delivered on 1 March 1932. The revolutionaries were defended by
Barrister Sarat Chandra Bose, however later, due to certain financial constraints they could not afford the services of
Sarat Chandra Bose, it was then that
Barrister Birendranath Sasmal stepped in and refused to charge any legal fees from the revolutionaries. His courtroom actions proved to be quite effective as only twelve of the defendants were sentenced to deportation for life, two received three-year prison sentences and the remaining 32 individuals were acquitted. The twelve deported to
Andaman included Ganesh Ghosh, Lokenath Bal, sixteen-year-old Ananda Gupta, and Ananta Singh.
Capture and death of Surya Sen The Chittagong revolutionary group suffered a fatal blow when Masterda Surya Sen was arrested on 16 February 1933 from Gairala village after a tip-off from an insider of the group. For the reward money, jealousy, or both, Netra Sen told the British Government that Surya Sen was at his house. But before Netra Sen was able to get his ₹10,000 reward, he was assassinated by the revolutionaries. Surya Sen was hanged by the British administration on 12 January 1934. ==Film adaptations==
