During the ensuing feast the Khazar leaders received ample gifts in the shape of earrings and clothes, while the yabghu was promised the hand of the emperor's daughter, Eudoxia Epiphania. The siege dragged on without much progress, punctuated by frequent sallies on the part of the besieged; one of these claimed the life of their king. After two months the Khazars retreated to the steppe, promising to return by the autumn. Tong Yabghu left young Böri Shad, either his son or nephew, in charge of the remaining forty thousand which were to assist Heraclius during the siege. Before long these departed as well, leaving the Byzantines to continue the siege alone and prompting jeers from the besieged. When the Georgians ironically referred to the Emperor as "the goat," hinting at his incestuous marriage, Heraclius recalled a passage from the

Conclusion

After the triumph of Heraclius, Tong Yabghu hastened to resume the siege of Tiflis and successfully stormed the city in winter. "With their swords raised, they advanced on the walls, and all this multitude, climbing upon each other's shoulders, rose up the walls. A black shadow fell upon the wobegone citizens; they were vanquished and lost their ground," Movses narrates. Although the Georgians surrendered without further resistance, the city was looted and its citizens were massacred. The Persian governor and the Georgian prince were tortured to death in the presence of Tong Yabghu. The Gokturks, renowned for their expertise in hand-to-hand combat, never excelled in siegecraft. For this reason Gumilev attributes the taking of Tiflis to the Khazars. There are good reasons for believing that this success encouraged Tong Yabghu to grander designs. This time he planned to incorporate Aghvania into his khaganate, rather than to wield a usual campaign of plunder. Before returning to Suyab he instructed Böri Shad and his generals to "spare the lives of the rulers and nobles of that land, in as much as they come out to meet my son, surrender to my rule, concede their towns, castles, and trade to my troops". These words indicate that Tong Yabghu was eager to retain control of the westernmost portion of the
