Battle of Szack was one of the major battles between the Polish Army and the Red Army fought in 1939 in the beginning the Second World War.
At 8 o'clock in the morning the Soviet tank unit (composed mostly of the T-26 tanks) started a direct assault on Polish positions. When the tanks were only some 500 metres from the Polish lines the Polish anti-tank guns opened fire. Soon they were joined by the infantry and the 75 mm artillery. All Soviet tanks were destroyed and Polish battalion was ordered to attack the town of Szack. The Soviet units were taken by surprise and after a short hand to hand fight the Soviet forces were routed. Only a small part of the motorised infantry managed to retreat, but had to leave behind all their lorries, artillery and 9 T-26 tanks. The Poles also captured the staff headquarters.
