Vickers Light Mk VI B

The Vickers Light Mk VI B was a British light tank, produced by Vickers-Armstrongs in the late 1930s, which saw service during World War II.

Vickers Light Tank Mk VI

The Vickers Mk VI was the sixth in the line of light tanks built by Vickers Armstrongs for the British Army during the interwar period. The company had achieved a degree of standardisation with their previous five models, and the Mark VI was identical in all but a few respects. The turret, which had been expanded in the Mk V to allow a three-man crew to operate the tank, was further expanded to give room in its rear for a wireless set. The weight of the tank was increased to 10,800 pounds which although heavier than previous models actually improved its handling characteristics, and an 88 horsepower engine was added to the model to increase its maximum speed to 35 miles per hour. It had the Horstmann coil-spring suspension system which was found to be durable and reliable, although the fact that the tank was short in relation to its width and that it pitched violently on rough ground made accurate gunnery whilst moving exceptionally difficult. The Mk VI possessed a crew of three consisting of a driver, gunner and commander who also doubled as the radio operator, between 4 millimetres and 14 millimetres of armour, which could resist rifle and machine gun bullets, and its armament consisted of one water-cooled .303 inch and one .50 inch Vickers machine gun.

Production of the Mk VI began in 1936 and ended in 1940 with 1,682 Mark VI tanks having been built. Many of those produced were actually variants designed to solve problems found with the original design. The Mk VIA had a return roller removed from the top of the leading bogey and attached to the hull sides instead, and also possessed a faceted cupola. The Mk VIB was mechanically identical to the Mk VIA but with a few minor differences to make production simpler, including a one-piece armoured louvre over the radiator instead of a two-piece louvre, and a plain circular cupola instead of the faceted type. 

A small number of specialized variations were also built based on the Mk VI chassis. The Tank, Light, AA Mk I was built in the aftermath of the Battle of France and was intended to act as a counter-measure against attacks by German aircraft. It featured a power-operated turret fitted with four 7.92 mm Besa machine guns; a Mk II was produced which was mechanically similar but had improvements, such as better quality sights for the machine guns and a larger turret for easier access. A variant on the Mk VIB was produced for service with the British Indian Army, in which the commander’s cupola was removed and replaced with a hatch in the turret roof.

Operational history

When the Mk VI was first produced in 1936, the Imperial General Staff considered the tank to be superior to any light tank produced by other nations, and well suited to the dual roles of reconnaissance and colonial warfare. Like many of its predecessors, the Mark VI was used by the British Army to perform imperial policing duties in British India and other colonies in the British Empire, a role for which it and the other Vickers-Armstrongs light tanks were found to be well suited. When the British government began its rearmament process in 1937, the Mk VI was the only tank with which the War Office was ready to proceed with manufacturing; the development of a medium tank for the Army had hit severe problems after the cancellation of the proposed “Sixteen Tonner” medium tank in 1932 due to the costs involved, and cheaper models only existed as prototypes with a number of mechanical problems. As a result of this, when the Second World War began in September 1939, the vast majority of the tanks available to the British Army were Mk VI’s.

When the Battle of France began in May 1940, the majority of the tanks possessed by the British Expeditionary Force were Mark VI variants; the seven Royal Armoured Corps divisional cavalry regiments, the principal armoured formations of the BEF, were each equipped with 28 Mk VIs. The 1st Armoured Division, elements of which landed in France in April, was equipped with 257 tanks, of which a large number were Mk VIB and Mk VICs. The 3rd Royal Tank Regiment, which formed part of the division’s 3rd Armoured Brigade, possessed by this time 21 Mark VI light tanks.

The Mk VIB was also used in the North African campaign against the Italians late in 1940 with the 3rd Hussars and the 7th Armoured Division. Late in 1940 the British had 200 light tanks (presumably the Mk VIB) along with 75 cruiser tanks (A9, A10, A13) and 45 Matilda IIs. An attack by the 3rd Hussars on 12 December 1940 resulted in the tanks getting bogged down in salt pans and severely mauled. The 7th Armoured Division had 100 left on 3 January 1941 and 120 tanks on 21 January at which time they were used in flanking far into the rear and gathering up scattered Italian troops, sometimes joining or leaving the main attacks to the Cruiser and Matilda II tanks. The 2nd Royal Tank Regiment continued to battle the Italians with light tanks as late as 6 February 1941.

Being widely used by the British Army, the tank participated in several other important battles. The Mk VIB made up a significant amount of the tanks sent over to the Battle of Greece in 1941, mostly with the 4th Hussars. Ten Mk VIB tanks fought with the 3rd The King’s Own Hussars during the Battle of Crete. The same armoured unit had previously embarked three MK VIB tanks for the Norwegian Campaign but they were lost in transit to a German aircraft attack.
