"The plan which Montgomery presented to Eisenhower at their meeting on August 23rd was bold enough, but it meant halting Patton and confining the Third Army to the defensive role of flank protection during the advance of the Second British and First American Armies to the Ruhr. Eisenhower's first reaction was that, even if it was militarily desirable (which he did admit), it was politically impossible to stop Patton in full cry. "The American public," said Eisenhower, "would never stand for it; and public opinion wins war." To which Montgomery replied, "Victories win wars. Give people victory and they won't care who won it.""
