context: The siege of Kanpur was a key episode in the 1857 sepoy uprising. The British besieged in Kanpur were not ready for a long siege and surrendered the city to rebel forces under the command of Nan Sahib in exchange for a safe exit to Allahabad. However, due to doubtful circumstances, their evacuation from Kanpur turned into a massacre, where most of the British died. Captured were later executed. When the forces of the British East India Company, directed to help from Allahabad, reached Kanpur, the circumstances of the massacre (known as the Bibigar massacre) became known. 120 British women and children captured by sepoys were hacked to death and dismembered with the help of bill hooks, the remains were thrown into the nearest body of water to hide traces of the crime. During the capture of Kanpur by British forces and the aftermath of the massacre, the furious British subjected the captured sepoy rebels and civilian large-scale punitive measures. The news of the massacre hardened the British lower ranks and gave rise to the battle cry "Remember Kanpur!" [1] [2].
