This condition of things was ended by Wellesley's victories at Assaye and Argaon (1803), which forced the Bhonsla raja to cede his territories south of Gawilgarh and Narnala fort and east of Wardha river.
It likely predates 1400 CE as Firishta -the Persian historian- records that Ninth Badshaha Shahbudeen Ahmad Shah I Wali (1422 CE to 1436 CE) during construction of the Gawilgarh fort, made repairs to Narnala fort when he camped at Achalpur (Elichpur) from 1425 to 1428.
