Firishta's History (Gulshan-i Ibrāhīmī) 302: JAM BANY.

302

On the death of Jam Choban, his nephew Jam Bany, the son of Jam Afra, having set up his claims to the government, established them, and succeeded his uncle Jam Choban. During his reign he publicly asserted his independence from the throne of Dehly, and refused to pay the accustomed tribute. Owing to this, in the year 762, Feroze Toghluk of Dehly marched with an army to Sind. Jam Bany, incapable of making resistance, fled, but having previously secured a large quantity of provisions and forage for his cattle, he laid waste by fire for many miles the surrounding country. By this stratagem his enemies were reduced to the utmost distress for forage, and compelled to fall back on the cultivated plains of Guzerat, where Feroze remained during the rainy season. After which the grass having grown, and being too green to be burned, Feroze was enabled to prosecute his march into Sind. Jam Bany was now reduced to submit to the Dehly arms, and threw himself on the mercy of Feroze Toghluk, who appointed his own governor over the provinces of Sind and Tutta, and returned to Dehly accompanied by Jam Bany, and other principal Sind chieftains in his train. Being some time after perfectly satisfied of their fidelity, he reinstated Jam Bany in his government, which he resumed with all his former dignities. Shortly after this he died, having reigned for a period of fifteen years.
