In 1123 he was captured by Balak of Mardin, and confined in Kharput with Joscelin, his successor in the county of Edessa, who had been captured in the previous year.
Of Kharput the Murad is joined by its principal tributary, the Peri Su, which drains the wild mountain district, Dersim, that lies in the loop between the two arms. The Murad Su is of greater volume than the Frat, but its valley below Mash is contracted and followed by no great road.
Wide, and is crossed by a ferry (altitude, 2 4 25 ft.), on the Sivas-Kharput road.
At the ferry on the Malatia-Kharput road (cuneiform inscription) it flows eastwards in a valley about a quarter of a mile wide, but soon afterwards enters a remarkable gorge, and forces its way through Mount Taurus in a succession of rapids and cataracts.
Happily for Kaikobad, the princes mistrusted the power of the Egyptian, and it proved a difficult task to penetrate through the mountainous, well-fortified accesses to the interior of Asia Minor, so that the advantage rested with Kaikobad, who took Kharput, and for some time even held Harran, Ar-Roha and Rakka (1232).
