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
