The story of Finnish tanks during the Second World War isn't exactly a happy one. From a manpower point of view they did extremely well, with tank crews showing high levels of skill and courage. On the equipment side of things however the situation was dire. Finland had ordered 32 Vickers 6 ton MK.E's before the war, but to save money they'd been ordered without lots of fittings or equipment. They lacked any guns or sights, any radios, even the drivers seats were missing. By the time the Winter War broke out 26 tanks had been delivered. During the summer of 1939 the tanks were briefly armed with the 37mm guns loaned from Finland's FT-17's, so the Vickers tanks could be used in war games.
The attack with several companies of infantry and two battalions of artillery in support was to cross a band of swampy terrain and slam into the Soviet front-line, tearing the top off the salient. Then the Finish infantry battalion at the head of the salient would pass through the counter attacking force and stop the penetration of Russian forces attempting to recapture the town. Don't be fooled by the description of "town", despite being the second largest settlement in the area it was mostly a combination of wooded areas and open cultivated fields with houses dotted about.
It failed to get off to a very auspicious start when tank 644 drove into a ditch and damaged the turret. Unable to fight the tank had to return to base.
Of the five remaining tanks all were destroyed, several whilst trying to inspire the infantry to follow them into close assaults. Three were destroyed in the lightly wooded areas. One, commanded by the platoon leader managed to reach a point where he could see the frozen lake on the other side of field. However his tank was hit and the crew forced to bail out. In return the Soviets lost at least three tanks, although the Soviet High Command claimed to have destroyed six enemy tanks for no loss.
