Design

In 1936, while the Matilda I was still in pre-production phases, it was decided an infantry tank would need to be able to withstand anti-tank fire from enemy guns and tanks.⁵ A tank that could carry more than just a machine gun was decided upon. The Matilda I couldn't have a larger turret installed so a new design was started in November 1936. The Design Department at Woolwich Arsenal was given the task.

During trials improvements were made to the gearbox, suspension, and air cleaners.

First British tank to have diesel engines. It was difficult to mass produce due to the size and shape of the armor castings. The side skirts were one piece and cause production to slow down. The mud chutes were reduced from 6 to 5¹² to help speed up production.

The Matilda couldn't be up-gunned as the turret ring was too small.¹

Crew

The driver sat in the middle behind the nose armor plate.¹⁰ There was a cupola for the commander but it didn't have good visibility. The Frazer Nash Company developed the hydraulic power for the turret.

Prototype

The Vulcan Foundry made wooden prototypes in April 1937. It was another year before a mock-steel prototype was produced.

Production

An order for 65 was placed in December 1937 and was shortly increased into 165.

Initially produced by the Vulcan Foundry in Warrington¹², Lancashire.^1,8 In June 1938 contracts for production were placed with Fowler, Ruston and Hornsby, and later LMS, Harland and Wolff and North British Locomotive Co.¹

• Matilda with Carrot:¹² 600lb HE demolition charge.¹² Used for blowing gaps in obstacles.
• Matilda Murray: Improved flame thrower. Produced in 1945.
• Matilda with Inglis Bridge: Light bridge on a track pushed ahead of Matilda. Used only in training.
• Matilda with Trench Crossing Device: Device pushed ahead on tracked bogies for spanning gaps for infantry and light vehicles to cross.

Australia

• Matilda Frog:¹² Flame thrower version.^1,5,12 25 vehicles in late 1944. Used in Borneo in 1945.⁸
• Matilda Murray FT: Modified Frog with cordite operated flame thrower instead of gas-pressure.⁴ Produced in 1945.⁴ Carried 50 gallons of flame fuel.⁴
• Matilda Dozer: Developed box shaped blade dozer.⁵
• Matilda Hedgehog: A seven barrel Naval Hedgehog was mounted on the rear of the Matilda.⁴ They could be fired individually or all at once.⁴

Usage

At the outbreak of the war in September 1939 only 2 were in service.⁸

Only British tank to server throughout entire war.¹

France

Used by the 4th and 7th Royal Tank Regiments¹ in France at Battle of Arras¹, on May 21, 1940, against the German 7th Panzer Division and SS Totenkopf.⁸

North Africa

Used in Africa and the Mediterranean. Fought the Italians at Sidi Barrani, Tobruk, Bardia, Keren (Eritrea).¹ Its last battle was at Alamein in July 1942.

Was used by the 42nd and 44th Royal Tank Regiments in Egypt and Cyrenaica.⁸

A squadron of the 4th Royal Tank Regiment was used in Eritrea with the 4th Indian Division.⁸

Half squadron of the 7th Royal Tank Regiment was lost on Crete.⁸

At the Second Battle of Alamein in October 1942, the 6th, 42nd, and 44th Royal Tank Regiments contained detachments of the Matildas and some Scorpions.⁸

While fighting in Libya in 1940 and 1941 it was nearly invulnerable to antitank fire. Became known as the Queen of the Battlefield. However, once the Germans brought 88 mm Flak guns this dominance was over.

Soviet Union

Some were sent to Russia.⁸

Australia

Many were supplied to Australia.⁴
