1944, and its last, also shortly after 18:00, from its last gun position at Veenheusen in Germany, a short distance from Emden, on 4 May 1945. In the course of 10 months in action, the 7th occupied about 60 gun positions, fired nearly 70,000 rounds of 100-pound shells in support of three Canadian divisions, most of the British divisions and the 1st Polish Armoured Division, all of the British 21st Army Group. The major battles in which the 7th was engaged were of course Normandy, the Scheldt and the Rhineland. The fire program for the opening of the latter is reported to have been the largest in the West during the war: at 05:00 on 8 February 1945, 1,400 British and Canadian guns of all calibres opened fire at once in support of the British XXX Corps, consisting for the opening of the battle of four British divisions and the 2nd Canadian Infantry Division attacking east from Nijmegen into Germany. Included in the preliminary bombardment, which ended at 09:30, were 16 medium regiments (13 Royal Artillery and three Royal Canadian Artillery. This was followed at 10:00 by the 2½-hour barrage in support of XXX Corps infantry attacking into Germany. In the ten months in which the 7th Medium was in action it had 124 casualties, of which 35 were killed and 89 wounded (some of the latter returned to the unit on recovery). In Normandy, during Operation Totalize, on 8 August 1944, a group of American bombers dropped their ordnance right on top of the 7th medium regiment, 12th battery, Royal Canadian Artillery. "The great problem on our side was road space, and it was while waiting in our gun positions, still firing at the retreating German forces, that the first disaster of the campaign befell us. A flight of American Fortresses flying high over 12th Battery area unloaded their bomb load right on top of the battery and on a nearby ammunition depot. B troop received most of the damage and Lt. J.E. Clark and ten other ranks were killed or died of wounds shortly afterwards. Captain W.G.Ferguson and eighteen other ranks were wounded and evacuated" Several G.P.O.s from the 7th became 'Air Observation Post' pilots with No. 665 Squadron RCAF, and No. 666 Squadron RCAF: Lt. A.B. Culver, Lt. R.G. Everett, and Lt. R.A.S. Perley. The 7th Medium Regiment, Royal Canadian Artillery, was disbanded on 8 June 1945.
