Matilda Hart Biography & Facts

The Infantry Tank Mark II, better known as the Matilda, is a British infantry tank of the Second World War. The design began as the A12 specification in 1936, as a gun-armed counterpart to the first British infantry tank, the machine gun armed, two-man A11 Infantry Tank Mark I. The Mark I was also known as Matilda, and the larger A12 was initially known as the Matilda II or Matilda senior. The Mark I was abandoned in 1940, and from then on the A12 was almost always known simply as "the Matilda". With its heavy armour, the Matilda II was an excellent infantry support tank but with somewhat limited speed and armament. It was the only British tank to serve from the start of the war to its end, although it is particularly associated with the North Africa Campaign. Only two were available for service by the outbreak of World War II in 1939. It was replaced in front-line service by the lighter and less costly Infantry Tank Mk III Valentine beginning in late 1941. Development history The split between the infantry tank and cruisers had its origins in the First World War division between the first British heavy tanks and the faster Whippet Medium Mark A and its successors the Medium Mark B and Medium Mark C. During the interbellum, British tank experiments generally followed these basic classifications, which were made part of the overall doctrine with the work of Major-General Percy Hobart and the influence of Captain B.H. Liddell Hart. In 1934, Hobart, the then "Inspector, Royal Tank Corps", postulated in a paper two alternatives for a tank to support the infantry. One was a very small, heavily armoured, machine gun-armed model that would be fielded in large numbers to overwhelm the enemy defences. The other was a larger vehicle with a cannon as well as machine guns and heavier armour proof against enemy field artillery. Vickers designed a tank to a General Staff specification based on the first option as the A11 Matilda. Within the limitations of military finances, the Master-General of the Ordnance, Hugh Elles, went for the smaller machine gun tank and the larger cannon-armed version did not proceed. This requirement was passed to Vickers-Armstrongs which had a prototype (A11E1) but with armour proof against current anti-tanks guns ready by September 1936. The first suggestion for a larger Infantry Tank was made in 1936, with specification A12. The design was produced by the Royal Arsenal, Woolwich, and Vulcan Foundry was selected as the manufacturer. A12 used a number of design elements of the A7, a medium tank that was built in limited numbers in the early 1930s whose mechanical layout was used for many following designs. With its greatly increased armour, a lack of power was seen as a problem. The solution was to use two AEC straight-six water-cooled diesel engines, used in London buses, providing up to 87 hp each. These were linked along a common shaft. Suspension was to use the "Japanese Type" bell crank suspension used on the A7. Vulcan received a contract for two wooden mock-ups and two mild-steel prototypes in November 1936. The first mock-up was delivered in April 1937 and the A12E1 prototype in April 1938. The prototypes proved excellent in a 1,000 miles (1,600 km) test, resulting in only a few changes to improve the gearbox, suspension and cooling. When war was recognised as imminent, production of the Matilda II was ordered and that of the Matilda I curtailed. The first order was placed shortly after trials were completed, with 140 ordered from Vulcan in June 1938. Design The Matilda Senior weighed around 27 long tons (27 t; 30 short tons), more than twice as much as its predecessor, and was armed with an Ordnance QF 2-pounder (40 mm) tank gun in a three-man turret. The turret traversed by hydraulic motor or by hand through 360 degrees; the gun could be elevated through an arc from −15 to +20 degrees. One of the most serious weaknesses of the Matilda II was the lack of a high-explosive round for its main gun. A high-explosive shell was designed for the 2-pounder but was rarely issued, as the shell explosive charge was so small. The main weapon against unarmoured targets was its machine gun. The Matilda II had a conventional layout, with the driver's compartment located at the front of the tank's hull, the fighting compartment with the turret in the centre and the engine and transmission housed in the rear. The driver's position was normally accessed by a single hatch in the roof of the hull, and protected by a rotating armoured cover which could be held locked in either fully open or closed positions; emergency egress was made possible by a large escape hatch under the driver's seating position. The driver also had a direct vision viewing port with manually operated armoured shield and a single Mk IV periscope to use when buttoned up. Like many other British infantry tanks, it was heavily armoured. The front glacis was up to 78 mm (3.1 in) thick; the nose plates top and bottom were thinner but angled. The sides of the hull were 65 to 70 millimetres (2.6 to 2.8 in) and the rear armour, protecting the engine to sides and rear, was 55 millimetres (2.2 in). The cast, cylindrical three-man turret was seated on ball-bearing ring mount and its armour was 75 mm (2.95 in) all round. The turret was laid out such that the gunner and commander were seated in a laddered arrangement on the left side of the gun, and the loader on the right. The commander was given a rotating cupola with a two-piece hatch and a single panoramic Mk IV periscope installed in the forward-facing hatch door. The same device was also mounted in a fixed position in the turret roof, forward of the commander's cupola, and giving the gunner some situational awareness and target finding capabilities. The loader used a single, rectangular hatch in the turret's roof on the right side. The turret was equipped with a basket around which much of the ammunition stowage was contained. The turret had a power traverse system used under normal conditions, and a manually-operated mechanical emergency assist. The turret roof, hull roof and engine deck were 20 millimetres (0.79 in). The armour varied in strength from IT.80 to IT.100 The armour of the Matilda was the heaviest of its era. Contemporary German Panzer III and Panzer IV tanks had 30 to 50 millimetres (1.2 to 2.0 in) hull armour, while the T-34 had 40 to 47 millimetres (1.6 to 1.9 in) (angled at 60 degrees). Matilda's side and rear armour was relatively heavy even at the end of the war when tanks like the M4 Sherman carried about 40 mm, and late models of the Panther carried 50 mm. The shape of the nose armour was based on Christie's designs and came to a narrow point with storage lockers added on either side. The heavy armour of the Matilda's cast turret became legendary; for a time in 1940–1941, the Matilda earned the nickname "Queen of the Desert".
