On 18 August 1941, an alone KV-1 (the number 864, the commander was lt.Kolobanov) was dug in and camouflaged near Krasnogvardeysk town (Leningrad area). The tank had an order to defend the road from Kinigsep. Four more KVs were ordered to defense two other roads. All tanks got double ammoloads, 2/3 of rounds were armor piercing. An offensive of 8th German panzer division was expected. Kolobanaov's KV had great hidden position in the woods on the hill, the crossroad located down there between swamps.
In the next day German motorcycle recon troops, halftrack and one light track passed by road. Five minutes later the expected column of 43 tanks appeared and filled the road. The 1st Soviet round flamed the head tank, after two more shots the 2nd tank was flamed too. Then Kolobanov opened fire on column's tail and flamed the last tank: the Germans were locked. They even couldn't note Soviet tank and opened no-target-fire. Tried to run, some tanks were immobilized in the swamp. The chaos established on the road. Soviet tankers killed 22 German tanks during 30 minutes. Then the KV was spotted by the Germans and they opened aimed fire. In spite of impossibility of German tank guns to penetrate thick KV's armor, knocking rounds made terrible working conditions for Soviet crew. One of German rounds struck the turret ring and the KV was forced to leave its trench and maneuver by whole hull for aim. Then the Soviets noted two German towed guns appeared on the crossroad. The first shell disabled one gun, but another gun managed to do one shot and damaged KV's periscope. Than that gun was destroyed too. Also ammo was almost out, and Kolobanov got congratulations via the radio and an order to go back. Already three another KVs were on the way to the battlefield, and they killed 20 more German tanks.
There were destroyed 42 German tanks total and two guns. Kolobanov's tank got 135 hits, but no one penetration.
Kolobanov was awarded with the Order of Lenin, Usov (driver) with the Order of the Red Banner.
