On August 30, a detachment led by General A.B. Gorbaty defeated Kazan’s field forces and took control of the Arsk side of the city. The city’s water supply system was destroyed, and sections of the walls were breached. By September 30, the siege ring had tightened, with only a moat remaining between the Russian siege towers and the fortress. On October 1, during the Feast of the Protection of the Virgin, the moat was filled in, tunnels were dug under the city walls, and the walls were blown up. | On August 30, a detachment led by General A.B.
