In early 1945, XXX Corps took part in Operation Veritable, during which the German Army was forced back over the Rhine. The corps employed firepower on a massive scale, and "every trick that had been learnt during the past two and a half years was brought into play, and several new ones added". For a short period XXX Corps had nine divisions under its command. Before the operation, Horrocks accepted an offer to use Bomber Command to attack the town of Cleves, assisting the advance of the 15th (Scottish) Infantry Division. The bombers released of high explosive that devastated the town. Horrocks later said that this had been "the most terrible decision I had ever taken in my life" and that he felt "physically sick" when he saw the bombers overhead. Operation Veritable was successful; by the evening of 9 February (D+1) XXX Corps had broken through the Siegfried Line and into Germany with only light casualties. Bremen was captured on 26 April, exposing the Sandbostel concentration camp, Stalag X-B. The corps had reached Cuxhaven by the time hostilities ceased.
