As a heavy artillery regiment, the 59th remained in England on coastal defence duties until 1944. In July, following the Normandy Landings, the 59th crossed the English Channel and on July 6 disembarked at Courseulles-sur-Mer where the 3rd Canadian Infantry Division had landed a month before. Once in France, the 59th served as part of the Army Group Royal Artillery of the British 21st Army Group. The unit first went into action supporting Battle of Caen, and later bombarded German forces in the Falaise Pocket. From here, the 59th participated in the major battles of North-West Europe, including supporting the advance of XXX Corps during Operation Market Garden and in support of American forces during the Battle of the Bulge. The 59th ended the war in Germany, firing its last shots against Hamburg on May 2, 1945. During the North-West Europe campaign, the main guns of the 59th were the 7.2" Howitzer and the American-made 155mm 'Long Tom'.
