The unit served at the Battle of Cambrai where, along with III Corps of the Third British Army, achieved complete surprise and pushed the German forces out of the town.

The Battalion were awarded the Croix de Guerre avec Palmes as a regimental decoration, an honour that is shared with only three other units in the British Army, all of which are infantry.

Along with this, the regiment's tanks and their crews often moved around the country to various gunnery ranges, such as at Bovington Camp in Dorset and Castlemartin in Wales.

In a combined assault of land, naval and air forces, the port city of Le Havre was taken in three days, despite being considered "one of the strongest fortresses of the Atlantic Wall".

After its rest period, 9th RTR moved into the Netherlands and took part in enlarging the Nijmegen Salient in support of the 51st (Highland) and 49th (West Riding) Divisions.

Later on in the Dutch campaign, the 9th participated in Operations Rebound and Thruster, which led to the capture of Roosendaal and aided the clearing of the banks of the River Scheldt.

Between late December 1944 and the end of January 1945, 9th RTR aided in victory in the Ardennes, acting as a defensive force near Liege, under the command of the First US Army.

Between March and April, the 9th had an extended period of refitting and maintenance, repairing or replacing tanks that had travelled thousands of miles and participated in countless engagements, anticipating the final push across the Rhine.
