Marichjhapi was the northern most forested island of the Sundarbans. The last batches of refugees were of nimnobarno identities (lower castes) and those refugees especially from Khulna preferred settling in the islands of Sundarbans, where cultivable wastelands were available. The United Central Refugee Council, a leftist organization, first came with the idea of settlement of the East Bengali refugees in Marichjhapi. They submitted a memorandum to Dr. B. C. Roy with a statistics that the government might offer at least 6875 families there in a total area of 65.6 sq. km. in 12 thousand acres of land. Dr. B. C. Roy also agreed that his government located 5000 bighas of lands in the Marichjhapi Island. Jyoti Basu promised the refugee leaders from the Mana Camp on January 25, 1975 that if the communists finally rose into power in West Bengal, they would certainly advocate settling down these refugee families from Dandyakaranya to Marichjhapi. Again in the All India Refugee Conference, which organized in the Mana Camp for the year 1975, few communist leaders including Ram Chatterjee, Kripa Sindhu Saha and Jomburao Dhoute from Forward Block promised the refugees to bring them back to West Bengal, once they would be in power. But, after they came to power in West Bengal with the help of refugee vote banks, a representative from Dandyakaranya visited Jyoti Basu, the Chief Minister regarding their wish to get a legal permission to be in Marichjhapi in future. Up till March 1978, the leftists’ leaders encouraged the refugees to settle down there, if they decided to migrate. But, when about 30,000 east Bengali refugees of various inhospitable areas somehow managed to sail to Marichjhapi, they were brutally evicted by using police force for violating the Forest Acts. The Marichjhapi incident finally demonstrated that the Bengali refugees have come to the dead end of their journey. How the left betrayed the refugees after coming into power was another story. It was a matter of ‘double betrayal’ for those refugees.
