Amid the chaos in Cawnpore in 1857, Nana Sahib entered the British magazine with his contingent. The soldiers of the 53rd Native Infantry, which was guarding the magazine, were not fully aware of the situation in the rest of the city. They assumed that Nana Sahib had come to guard the magazine on behalf of the British, as he had earlier declared his loyalty to the British, and had even sent some volunteers to be at the disposal of General Wheeler. However, Nana Sahib joined the rebels.
