Operation Veritable started on 8 February 1945. The operation was intended to be one of two pincers aimed at encircling the entrenched German forces. In this scenario British and Canadian forces would constitute the northern pincer of the attack, while U.S. forces would come up from the south to close the trap (Operation Grenade). The German army managed to prevent encirclement by destroying dams in the river Roer (not to be confused with the Ruhr river on the other side of the Rhine) which led to massive flooding; at some points the river was almost two kilometers wide. This flood forced the U.S. soldiers to postpone their assault. The Canadian and British forces had to go it alone. From the outset of the offensive, bad weather complicated Allied operations. General Horrocks, commanding the British forces, later said of the battle: “What was so maddening was that the whole thing could have been so easy if only the frost had continued”. A thaw turned the previously frozen ground into a quagmire, a situation that was aggravated by continuous rain and the fact that the German army had breached the banks of the Rhine. The Allies advanced slowly and were unable to fully exploit their superiority in numbers and equipment. On 23 February the water had retreated sufficiently to allow the U.S. forces to finally cross the Roer and fulfill their mission. In the words of the Allied Supreme Commander general Dwight D. Eisenhower: Operation Veritable “was some of the fiercest fighting of the whole war […] a bitter slugging match” between Allied and German forces.
