Tous led the Iranians in overcoming two major obstacles. They passed through the snow and cold of the mountains and then burned firewood to enter Turan. This was the start of the Iranian invasion of Turan. Due to their own negligence, the Iranians faced difficulties in campaigning and suffered a severe defeat. However, after getting rid of the snow and cold, the re-organized Tous Army continued to advance. First, they arrived at Garugard, where Tageuo ruled. Tageuo sent the shepherd Kaboodeh to estimate the number of invaders, but he was captured by the Iranians and killed. The next day, Tageuo gathered his men and confronted the Iranians. However, his forces were too few in number to defeat the Iranians, so they ultimately failed. Tageuo fled to the fort alone.
Bizhan chased Tageuo, but when Tageuo entered the castle, he saw his wife Espanoi, who was aware of the severe defeat. Both fled on horseback, but the horse soon ran out of breath. Tageuo was forced to leave his wife alone and went to Turan near
Afrasiab. Bizhan found Espanoi on the chase and brought him to the Iranian camp, but Tageuo arrived in Turan and reported what had happened. The easy victory made the Iranian army happy and overconfident. Afrasiab ordered
Piran to launch a surprise attack. According to
Shahnameh texts and images, the Iranians were severely defeated in the attack. More than two-thirds of the fighters were killed and many were injured. ==Name==
