The Soviet 9th Guards Mechanized Corps broke through to the Tordai Gorge and proceeded to surround the Hungarian 25th Reconnaissance Battalion. This breakthrough put the Soviet tanks at Szind, only four kilometers from the doorstep of Torda. The Hungarian 11th Infantry Battalion and the 10/2 Assault Artillery Battery counterattacked, surprising the tank crews of the Soviet 46th Guards Tank brigade in the process. Captain Janos Bozsoki, with his six Zrinyi II assault guns, knocked out approximately eighteen Soviet tanks , then scattered the Soviet infantry surrounding the 25th Reconnaissance Battalion. Five of the Zrinyi crews were wounded or killed in the action.
