Robert Orme, A History of the Military Transactions of the British Nation in Indostan… (1861)
“ This eastern part is the upper, and the only real fort; being inclosed and fortified with high stone walls and towers strongly built. The other inclosure, although called the lower fort, is only surrounded with a wall of loose stones, and was principally intended for the immediate refuge of the cattle and inhabitants on sudden alarm. The rock falls every where so steep, that the area of the fortified surface above is equal to half the base below. ”
