The division was created as part of the preparations for the Normandy invasion on 6 June 1944, D-Day.

Major-General Percy Hobart commanded the division and was in charge of the development of armoured vehicles that were solutions to problems of the amphibious landing on the defended French coastline; these unusual-looking tanks it developed and operated were known as "Hobart's Funnies".

They included tanks that floated, could clear mines, destroy defences, carry and lay bridges, and roadways.

Its vehicles were distributed as small units across the divisions taking part in the landings and subsequent operations.

The division remained in action during the North-west European Campaign, providing specialised support during assaults to the 21st Army Group and, occasionally, to American units outside 21st.
