As is well known, the 1857 mutiny of Indian soldiers in the Company Army – collectively known as sepoys – was prompted by the proposed introduction of a new weapon for general use, a rifled musket known as the Pattern 1853 Enfield. This weapon required a new kind of greased cartridge, the loading of which entailed a new “firing” drill. Controversies over this new cartridge and drill prompted discontent among the “native” soldiery, which ultimately led to the collective decision to refuse to touch the offending cartridge and, naturally, load the weapon – a refusal that constituted the “mutiny” phase of 1857. This chapter begins with a reexamination of this drill and the circuitous, controversial decision to order eighty-five elite “skirmishers” of the Bengal 3rd Light Cavalry to perform it in late April. Their refusal to obey that order led to their court-martial for mutiny and imprisonment. The violent revolt began two weeks later, but not in the cantonment proper. Rather, it began in a hybrid space of commerce, leisure, and recreation on the edge of the cantonment known as the “sadr” (main) bazaar. The bulk of the chapter is devoted to a description of the sadr bazaar and its denizens.
