to withdraw to Balkh without further serious fighting. A variant account given by _T_abarī relates an unsuccessful assault by the Türgesh on Asad’s camp on the morning following the “Battle of the Baggage,” which happened to be the feast of Fi_t_r (1st October 737). On the retiral of the Arabs, the Khāqān, instead of returning to his capital with the honours of the day, remained in _T_ukhāristān. Here he was joined by _H_ārith, who advised him to undertake a winter raid into Lower _T_ukhāristān while the Arab troops were disbanded, undoubtedly in the expectation that the local princes would again unite with him against Asad. The governor retained his army at Balkh until the winter had set in, and in the meantime the Khāqān summoned forces to join him from _S_ughd and the territories subject to _T_ukhāristān. The enumeration which _T_abarī gives of the troops accompanying the Khāqān on this expedition shows very clearly how completely Arab rule in Transoxania and the Oxus basin had been supplanted by that of the Turks. We are told that besides the Khāqān’s own Turkish troops and _H_ārith with his followers there were present the Jabghu, the king of _S_ughd, the prince of Usrūshana, and the rulers of Shāsh and Khuttal. It is fairly certain, of course, that the list is exaggerated in so far as the actual presence of the princes is concerned (it is in fact partially contradicted in other parts of the narrative), but it can scarcely be doubted that forces from some, if not all, of these principalities were engaged. On the evening of the 9th Dhuʾl-_H_ijja (7th Dec.) news reached Balkh that the Türgesh with their auxiliaries, numbering some 30,000, were at Jazza. Asad ordered signal fires to be lit and with the Syrian garrison of Balkh and what other troops he could muster from the district marched out against them. The governor of Khulm sent in a second report that the Khāqān, having been repulsed in an attack on the town, had marched on towards Pērōz Nakhshēr, in the neighbourhood of Balkh. From this point the enemy, avoiding Balkh, moved on Jūzjān and occupied the capital[96]. Instead of continuing his advance immediately, the Khāqān halted here and sent out raiding parties of cavalry in all directions, an action which put it beyond doubt that the immediate object of the expedition was not the capture of Merv but the rousing of Lower _T_ukhāristān against the Arabs. Contrary to _H_ārith’s expectations, however, the king of Jūzjān joined with the Arabs, who marched towards Shubūrqān by way of Sidra and Kharīstān. From the conflicting narratives in _T_abarī, it seems that Asad surprised the Khāqān in the neighbourhood of Kharīstān (or Sān) at a moment when his available forces amounted only to 4,000. A furious struggle ensued, which was decided in favour of the Arabs by an assault on the Khāqān from the rear, on the initiative of the king of Jūzjān. It is in connection with the battle, which he describes
