Early life
Biren was born on 20 June 1889 in the village of Baligaon in Bikrampur, Dhaka. He was the second child of father Umacharan Gupta and mother Basantakumari Devi. He lost his father at a very young age. n 1906, Birendra was admitted in the ninth class of Jalpaiguri district school. He later came to Calcutta and was inspired by the ideology of Kanailal Dutta, the martyred revolutionary who assassinated Naren Gonsai, the witness in the Alipore conspiracy case, and became involved in active revolutionary activities. During this time he associated himself with revolutionary activities as a disciple of Jatindranath Mukherjee alias Bagha Jatin.Shamsul Alam's murder
After the Alipore conspiracy case was filed in the Calcutta High Court, the secret revolutionary activities in Bengal became almost public. At its core were three royal officials - Inspector Nandalal Banerjee, Advocate Ashutosh Biswas and the notorious, DSP Shamsul Alam. Assassinating them became necessary for the revolutionaries. Inspector Nandalal Banerjee betrayed Prafulla Chaki and shot him dead. For this he got his price, when another revolutionaryExecution
A case was filed in the Calcutta High Court shortly after the murder of Shamsul Alam. This is the Howrah-Sibpur Conspiracy case as it is known. In this case, 48 people including Bagha Jatin were arrested on the charge of being involved in the murder of DSP Shamsul Alam. But it was almost impossible for the government to prove the allegations. Because Biren, the killer of Alam, did not answer a single question of the police. In this situation the government planned a heinous conspiracy. A paper similar to a secret proclamation of their revolutionary party was handed over to Birendra, which is not of that revolutionary party at all. Jatindranath Mukherjee 'signed' to that paper (Needless to say the signature is imitated) An article claims that the incident of Samsul's murder was premeditated by the police. The police spread rumours that Samsul Alam was not killed by Biren. Satish Sarkar (frictionous name) killed him. At the same time, in that article, Biren was mentioned as a police spy. Biren could not guess the point of this conspiracy of the police. He thought that Jatindranath had lied and proved him a traitor to his countrymen. Biren became desperate for this scandal and on the day before his execution (February 20, 1910) he confessed that he had killed Samsul on the orders of Jatindranath. In this confession of Birendra, many other revolutionaries including Jatindranath faced a deep problem. Biren was hanged on 21 February 1910 in the present Alipore Presidency Jail. 1910). On the day of his execution he kept smiling and he went to the gallows cheerfully. He stated in his confession that he had killed Samsul on the orders of Jatindranath. In this confession of Birendra, many other revolutionaries including Jatindranath faced a deep problem. However, in the end, the contemporary police administration could not take advantage of Biren's confession. There are basically two reasons for this. First, the administration did not get a chance to verify the veracity of the allegations leveled against them as Biren was hanged before the trial of the rest of the revolutionaries began. Second, the government failed to prove the interaction of the revolutionaries as power was decentralized among the revolutionary secret societies in the decision of the far-sighted Jatindranath. As a result, the administration was forced to release 33 of the 48 imprisoned revolutionaries, including Jatindranath. After his release from jail, Jatindranath was dismissed from his job and devoted himself entirely to revolutionary activities. Other revolutionaries similarly refocused on their work. Therefore, as a result of Biren's confession, the humiliation that the British government had hoped for in the revolutionary movement in Bengal was never realized.{{Cite book, last=Roy, first=Samaren, url=https://bn.m.wikipedia.org/wiki/%E0%A6%B9%E0%A6%BE%E0%A6%93%E0%A6%A1%E0%A6%BC%E0%A6%BE-%E0%A6%B6%E0%A6%BF%E0%A6%AC%E0%A6%AA%E0%A7%81%E0%A6%B0_%E0%A6%B7%E0%A6%A1%E0%A6%BC%E0%A6%AF%E0%A6%A8%E0%A7%8D%E0%A6%A4%E0%A7%8D%E0%A6%B0_%E0%A6%AE%E0%A6%BE%E0%A6%AE%E0%A6%B2%E0%A6%BE, title=M.
