The Gachtal plates of Go Pala have thrown fresh light on the achievements and date of Ratna Pala. An inscription states that Ratna Pala of Pragjyotisha-Kamarupa defeated King Rajyapala (908-40 AD) of Pala Empire of Bengal and advanced as far as the Ganges in the heart of Pala empire. This achievement is not mentioned in any earlier record of the family. The inscription mentioned Rajyapala of Bengal, advancing the dates of Pala's reign to the 1st half of the 10th century from the 1st half of the 11th century.
