Maunsell, a lieutenant in the 23rd Native Infantry of the Bengal Army set out on horseback in October 1812 from Agra, in what were then called the North-western Provinces, on a visit of inspection to Etawah, seventy-five miles south-east, accompanied by two sepoy orderlies and a horse carrying his belongings and equipment. All three were armed, Maunsell with sword and holster pistols, the sepoys with the Brown Bess musket and bayonet.
