When the Infantry Tank Mk. I which was also known as "Matilda" was removed from service the Infantry Tank Mk II simply became known as the Matilda.
Matilda I in The War That Came EarlyEdit
Matilda I's made up the majority of the British Armour in Europe when the Germans invaded France in 1939. Although the Matildas were more heavily armoured than the German tanks, they were under gunned with only a single rifle calibre machine gun, and their top speed of 8mph made it difficult for them to manoeuvre or retreat.
