One of the unexplored issues regarding the Revolt of 1857 is on the question of the greased cartridge – first, who spread the story/rumour that the greased cartridge contained cow and pig fat and by biting it while firing rifles, the sepoys, both Hindus and Muslims, will lose their caste and religion. Second, how did the story travel so fast like wildfire from Barrackpore to several parts of northern India? Even though 1857 is not my field as a specialist, I shall still try to address the said question with my limited knowledge on the subject.
