JĀN MUHAMMAD CHAṬṬHĀ (d. 1798), son of Ghulām Muhammad Chaṭṭhā, fled to Kābul on the eve of the conquest of the fort of Manchar in 1790 by Mahāṅ Siṅgh Sukkarchakkīā. He accompanied Shāh Zamān to India in 1797 and recovered his possessions on the River Chenāb in Gujrānwālā district with the aid of the Afghāns, but this was a short-lived gain, for Raṇjīt Siṅgh attacked his headquarters, Rasūlnagar, after the Shāh's return to Afghanistan. The besieged Chaṭṭhās, under Jān Muhammad, made a gallant resistance. However, they lost footing gradually. Jān Muhammad was killed by a cannon-shot and the fort surrendered (1798). Raṇjīt Siṅgh granted small jāgīrs or estates to the sons of Jān Muhammad and employed them in the irregular cavalry.
