Firishta's History (Gulshan-i Ibrāhīmī) 8.1.4

8.1.4

The King, in the year 422, having left Bulkh came to Ghizny, and sent an army to Kech and Mikran, causing the coin of both provinces to be struck in his name. The prince of those countries died about that time and left two sons, Abool Asakir and Eesa: the younger brother taking possession of the government, Abool Asakir had recourse for aid to the Emperor Musaood, to whom the fugitive prince promised an annual tribute, and to hold his dominions, when recovered, of him. Musaood accordingly sent an army with Abool Asakir, giving orders to his general to reconcile, if possible, the difference between the brothers, and to divide the country equally between them; but if this could not be effected, to put Abool Asakir in possession of the whole. The Ghiznevide army arrived on the frontiers; but so obstinate was Resa that he would accede to no terms of accommodation; and though deserted by many friends who joined his brother, he determined to decide the contest by the sword. He fought with great bravery, and was slain in the conflict. The provinces thus fell into the hands of Abool Asakir, who paid tribute henceforward to the Emperor of Ghizny.
