The British Mark V tank[note 1] was an upgraded version of the Mark IV tank, deployed in 1918 and used in action in the closing months of World War I, in the Allied intervention in the Russian Civil War on the White Russian side, and by the Red Army. Thanks to Walter Wilson's epicyclic gear steering system, it was the first British heavy tank that required only one man to steer it; the gearsmen needed in earlier Marks were thus released to man the armament.

The Mark V was, at first, intended to be a completely new design of tank, of which a wooden mock-up had been completed; however, when the new engine and transmission originally planned for the Mark IV became available in December 1917, the first, more advanced Mark V design was abandoned to avoid disrupting production. The designation "Mark V" was switched to an improved version of the Mark IV, equipped with the new systems. The original design of the Mark IV was to have been a large improvement on the Mark III, but had been scaled back due to technical delays. The Mark V thus turned out very similar to the original design of the Mark IV – i.e. a greatly modified Mark III.

In early 1917, some British tanks were tested with experimental powerplant and transmissions ordered by Albert Stern. These included petrol-electric schemes, hydraulic systems, a multiple clutch system, and an epicyclic gearbox from Major W.G. Wilson. Though the petrol-electrics had advantages, Wilson's design was capable of production and was selected for use in future tanks. Wilson then worked on the design of the tank that would use his gearbox.

The Mark V had more power (150 bhp) from a new Ricardo engine (also ordered by Stern). Use of Wilson's epicyclic steering gear meant that only a single driver was needed. On the roof towards the rear of the tank, behind the engine, was a second raised cabin, with hinged sides that allowed the crew to attach the unditching beam without exiting the vehicle. An additional machine-gun mount was fitted at the rear of the hull.

Production of the Mark V started at Metropolitan Carriage and Wagon at the end of 1917; the first tanks arrived in France in May 1918. Four hundred were built, 200 each of Males and Females; the "Males" armed with 6-pounder (57 mm) guns and machine guns, the "Females" with machine guns only. Several were converted to Hermaphrodites (sometimes known as "Mark V Composite") by fitting one male and one female sponson. This measure was intended to ensure that female tanks would not be outgunned when faced with captured British male tanks in German use or the Germans' own A7V.

The Mark V was first used in the Battle of Hamel on 4 July 1918, when 60 tanks contributed to a successful assault by Australian units on the German lines. It went on to take part in eight major offensives before the end of the War. Canadian and American troops trained on Mk Vs in England in 1918, and the American Heavy Tank Battalion (the 301st) took part in three actions on the British Sector of the Western Front in late 1918. The Canadian Tank Corps, however, did not see action and was disbanded after the war's end. Approximately 70 were sent to support the White Russian forces in the Allied intervention in the Russian Civil War and in the British North Russia Campaign. Most were subsequently captured by the Red Army. Four were retained by Estonian forces, and two by Latvia.


Mark V*

In an attempt to stop the tanks, the Germans began making their trenches too wide to be crossed. For example, trenches in the Hindenburg Line were widened to 11 or 12 feet, more than the British tanks' 10 feet trench-crossing ability. To counter this, Sir William Tritton developed the Tadpole Tail, an extension of the tracks to be fitted to the back of a tank and lengthen it by about 9 feet. However, it proved to be insufficiently rigid, and although several hundred were manufactured, the idea was abandoned. Then a Major Philip Johnson of the Central Tank Corps Workshops heard of this project and devised a plan of his own. He cut a Mark IV in half and inserted three extra panels, lengthening the hull by six feet. (It was believed for a long time that most Mark V* had been field conversions made by Johnson. It is now known that they were all new, factory-built to a new design). The V* had a reshaped rear cupola, incorporating 2 extra machine-gun mounts, and a door in each side of the hull, also with an extra machine-gun mount. The weight was 33 tons. Of orders for 500 Males and 200 Females, 579 had been built by the Armistice – the order was completed by Metropolitan Carriage in March 1919.[3]

It was also hoped that this longer tank might carry a squad of infantry with Vickers or Lewis machine guns, but the conditions inside were so extreme that the men became ill, and after some early experiments, the idea was abandoned.

Shortly before the end of the War, Britain supplied France with 90 Mk V*. They were not used in action, but remained in French service throughout the 1920s and 30s.

Note: the asterisk (*) in early British tank designations was usually pronounced as "star" when spoken, e.g., Mark Five-star, or Mark Five-star-star, etc.

Because the Mark V* had been lengthened, its original length-width ratio had been spoiled. Lateral forces in a turn now became unacceptably high causing thrown tracks and an enormous turn circle. Therefore Major Wilson redesigned the track in May 1918, with a stronger curve to the lower run reducing ground contact (but increasing ground pressure as a trade-off) and the tracks widened to 26.5 inches. The Mark V engine was bored out to give 225 hp and sited further back in the hull. The cabin for the driver was combined with the commander's cabin; there now was a separate machine gun position in the back. Of a revised order for 700 tanks (150 Females and 550 Males) only 25 were built and only one of those by the end of 1918.[3]

Combat history

The Mk V made its combat debut at the Battle of Hamel on 4 July 1918, successfully supporting Australian troops in an action that repaired the Australians' confidence in tanks, which had been badly damaged at Bullecourt. Thereafter Mk Vs were used in eight major actions before the end of the War.

During the Battle of Amiens in August 1918, 288 Mark V tanks, along with the new Whippet and Mk V*, penetrated the German lines in a foretaste of modern armoured warfare. This battle was also the Mk V*'s combat debut.

The American 301st Heavy Tank Battalion was equipped with 19 Mark V and 21 Mark V* tanks in their first heavy tank action against the Hindenburg Line on 27 September 1918. Of the 21 Mark V* tanks, 9 were hit by artillery rounds (one totally destroyed), 2 hit British mines, 5 had mechanical problems, and 2 ditched in trenches. The battalion, however, did reach its objective.

It has been at Bovington since 1925, and was used for demonstrations and filming.[8] While this tank is maintained in running condition, the Bovington museum had made the decision to not run it again, because of the wear and tear that would be inflicted on the now-fragile, historic vehicle.[9]

Eleven Mark V tanks survive. The majority are in Russia or Ukraine and are survivors of the tanks sent there to aid the White forces during the Russian Civil War.

Surviving vehicles

In 1945, occupying troops came across two badly damaged Mk V tanks in Berlin. Photographic evidence indicates that these were survivors of the Russian Civil War and had previously been displayed as a monument in Smolensk, Russia, before being brought to Berlin after the German invasion of the Soviet Union in 1941.[6] Accounts of their active involvement in the Battle of Berlin have not been verified.[7]

The last known use of the Mk V in battle was by units of the Red Army during the defence of Tallin against German forces in August 1941. The four Mk Vs previously operated by Estonia were used as dug-in fortifications. It is believed that they were subsequently scrapped.[5]
