Asad now planned a more ambitious expedition against Khuttal, partly in retaliation for the assistance given to _H_ārith, partly, it may be, to wipe off an old score. The chronology presents some difficulties at this point. _T_abarī relates two expeditions into Khuttal in the same year 119/737, both from the same source, but that which is undoubtedly the earlier is dated towards the close of the year (Rama_d_ān = September). Wellhausen avoids the difficulty by referring this expedition to 118, reckoning back from the appointment of Na_s_r b. Sayyār, the data for which are full and unimpeachable. This would seem the obvious solution were it not that the date given in the Chinese records for the assassination of Su-Lu, 738[94], agrees perfectly with _T_abarī’s dating of the Battle of Kharīstān in Dec. 737. The presence of Asad on the second expedition would then hang together with the “somewhat legendary” narrative of the Mihrjān feast. There seems reason, therefore, for dating this expedition in 120/738 and regarding it as having been despatched by Asad, though not actually accompanied by him. _T_abarī fortunately preserves also a short notice of the situation in Khuttal. The heir of as-Sabal, whose name is to be read as Al-Hanash, from the Chinese transcription Lo-kin-tsie[95], had fled to China, possibly on account of factional disturbances. On his deathbed as-Sabal appointed a regent, Ibn As-Sāʿijī, to govern the country until Al-Hanash could be restored. The moment was certainly opportune for making an expedition and Asad at first carried all before him. On his first appearance, however, Ibn As-Sāʿijī had appealed for aid to Su-Lu, who was at his capital Nawākath (on the Chu). The Khāqān, with a small mounted force including the _S_ughdian refugees, marched from Sūyāb (near Tokmak, on the Chu) to Khuttal in seventeen days, only to find Asad, warned of his approach by the regent, who was endeavouring to play both sides off against each other, in precipitate retreat. The baggage train had been despatched in advance under Ibrāhīm b. ʿĀ_s_im with a guard of Arabs and native troops from Chaghāniān but the main body was overtaken by the Turks as it was crossing the river and suffered severe losses. Asad, considering himself safe with the river between his army and the enemy, encamped and sent orders to Ibrāhīm to halt and entrench his position. The Turks, however, were able to effect a crossing; after an unsuccessful assault on Asad’s camp, they hastened to overtake the richer prize while the governor’s troops were too worn out to protect it. By sending a party under cover to fall on the troops of Chaghāniān from the rear while he himself attacked in front, the Khāqān forced an entrance into Ibrāhīm’s camp. Chāghān Khudāh, faithful to the last, himself fell with the greater part of his forces but the remainder of the garrison were saved by the timely arrival of Asad. According to the main account, the Arabs were allowed
