Britain's Infantry Tank Mk I, A11, Matilda Mk I, Matilda I Infantry Tank


In April 1934 the British General Staff discussed a proposal put forth by General Sir Hugh Elles of the Royal Tank Corps that covered the specs for an "Infantry" tank, well protected, with a machine gun as armament and go as fast as infantry on foot.13 Sir John Carden led the design team.13

Named after a cartoon duck.8,13 Another source says that Matilda was the original code word for the tank that was in the proposal created by John Carden.12,13

The steering, brake and clutches were adapted from the Vickers light tanks.1,13


Costs were kept down by using a commercial Ford engine and transmission.12

Engine was at rear which drove sprockets that were also at the rear of the tank.8


The turret was cast.13

The crew was limited to 2 because of severe cost restrictions, and thus there wasn't enough in the budget for 2 in the cast turret.


The body of the Matilda was riveted.13


Prototypes were given to the army for trials in September 1936.8


Production order for 60 was placed in April 1937.12,13 The order was later increased to 140.13

The first models were delivered in 1938 to the 1st Army Tank Brigade.

There were 65 available in September 1939 when the war started.8

The 1st Army Tank Brigade had 77 Matilda Is by May 1940.6 Went with 4th and 7th Royal Tank Regiment, and 1st Army Tank Brigade to France in 1940 and took part in battle of Arras. At the Battle of Arras there were 58 Matilda Is.6
