The Indian Museum is displaying a basalt inscription, the only epigraphic evidence in Bengali script about the capture of Kolikata
 

The stone has eight lines of inscription, in verses, known as payar. It says Chudamani Dutta fled to Kolikata to escape the persecution of Nawab Murshid Quli Khan and retuned to his village the year Siraj-ud-Daula sacked Kolikata.

The inscription was recovered from Sabiana village, North 24-Parganas, and refers to the great storm in 1737 and the bargi invasion in 1741, the two catastrophes that ravaged 18th century Bengal. Chudamani's psyche was scarred by the storm and the pillaging by the Marhatta cavalry, known as bargis, to collect chauth (revenue).
