JAN MUHAMMAD CHATTHA (d. 1798), son of Ghulam Muhammad Chattha, fled to Kabul on the eve of the conquest of the fort of Manchar in 1790 by Mahan Singh Sukerchakia. He accompanied Shah Zaman to India in 1797 and recovered his possessions on the River Chenab in Gujranwala district with the aid of the Afghans, but this was a short lived gain, for Ranjit Singh attacked his headquarters, Rasulnagar, after the Shah`s return to Afghanistan. The besieged Chatt has, under Jan Muhammad, made a gallant resistance. However, they lost footing gradually. Jan Muhammad was killed by a cannon shot and the fort surrendered (1798). Ranjit Singh granted small jagirs or estates to the sons of Jan Muhammad and employed them in the irregular cavalry.
