This small, two-man tank was very well armored for its era, and carried one Vickers .303 (7.7 mm) or Vickers .50 (12.7 mm) machine gun in a fully rotating turret. Despite being slow (top speed of 8 mph), cramped, and only armed with a single machine gun, the Matilda I had some success in the Battle of France in 1940, owing to its heavy armour which was proof against the standard German anti-tank guns. It carried a crew of two. Vickers-Armstrongs Limited produced 140 units, fifty-eight of which deployed to France in late 1939. The British withdrew this type from service in mid-1940, after the fall of France.
