Judging by the numbers of replacements ordered sent to or levied in Khurasan in the aftermath of the battle, Blankinship estimates the Arab losses at between 25,000 and 30,000, and that "probably not more than fifteen thousand Khurasani troops were left alive".[41] Although the Türgesh also suffered heavy casualties—Ibn A'tham gives the unverifiable figure of more than 10,000 dead[42]—the Arab losses at the Battle of the Defile led to a rapid deterioration of the Umayyad position in Central Asia. Junayd remained as governor of Khurasan until his death in early 734, but by this time the Muslims had lost control of everything north of the Oxus save for Bukhara, Kish, and the region of al-Saghaniyan.[43]
