Kalidas Ghosh (1909-2000), was born in Fultala, in the village Alka in Khulna, now in Bangladesh. In his very boyhood when he was hardly aged about 12 or 13, he was arrested by the British police as he hoisted the Indian National Flag in public in the Rajsahi Court complex raising the slogan "Vande Mataram" as a part of the Non-cooperation Movement (1920-21). He was arrested and had to appear ('Hazira') before the local police station every day and kept under strict surveillance for three years by the police.
While in college, Kalidas took an active part in the great 'Mail train Robbery' at Hili in 1933 and went under the concealment of identity. From there, he joined the Peasant Movement sensitizing the farmers around Chalon Beel located in the Patisar estate owned by Rabindranath Tagore. He was again arrested as a 'Rajbandi' (detenu) by the British police along with Purnananda Dasgupta (follower of Satya Basu), Dinesh Das (later a convict with a pending death sentence), Nalini Sengupta, Anantahari Mitra and so on.
After his release, while still a college student, he became a member of the secret society "Anushilan Samiti" which under the guise of yoga and physical exercise, used to teach 'Lathi Khela' (stick game), thereby imparting training in the use of arms-art and so on.
Kalidas actively joined the Non-cooperation movement and then the Salt Satyagraha (1930), led by Gandhiji. He was taken into custody, underwent trial, and was sentenced to rigorous imprisonment wherein he was brutally tortured by the British police. He served a total of 11 years of rigorous imprisonment in his lifetime, out of which 8 years encompassed the period between 1933 to 1941-42 in Andaman Cellular jail and later in Dumdum Central jail along with Nalini Sengupta. While deported to the Cellular jail he was incarcerated as prisoner number 21.
After his release in 1942, a sense of unrest grew in him and according to the doctor's advice, he was incorporated into the family life. It is to be noted that both Kalidas Ghosh and his brother Santosh Kumar Ghosh (1919 - 1995), a bachelor and 10 years junior to Kalidas, were inspired by the unfailing spirit of patriotism by their father Shri Gopal Chandra Ghosh who was an advocate in the Rajsahi Court. Santosh was a close associate of Kalidas in every anti-British movement and was tortured and imprisoned several times. Kamal Kumar Ghosh, their elder brother, could not be traced from a very young age as it is believed that he had already succumbed to British atrocities.
After independence, records of revolutionary activities were verified about Kalidas Ghosh and Santosh Kumar Ghosh from the Cellular Jail in the Andamans and Dum Dum Central jail, Calcutta, and both were conferred with 'Tamra Patra' as freedom fighters on 15.08.1972 on the 25th year of Independence by the then Prime-Minister Smt. Indira Gandhi in New Delhi. Locally in Basirhat, they were also felicitated with certificates along with some other freedom fighters like Satipada Sur, Parimal De, Tukurani Pal, and others.
