"Nevertheless, again there cropped up criticisms of Montgomery's "caution," which I had first heard among pressmen and airmen when he was conducting his long pursuit of Rommel across the desert. Criticism is easy- an unsuccessful attack brings cries of "butcher" just as every pause brings wails of "timidity." Such charges are unanswerable because proof or refutation is impossible. In war about the only criterion that can be applied to a commander is his accumulated record of victory and defeat. If regularly successful, he gets credit for his skill, his judgement as to the possible and impossible, and his leadership. Those critics of Montgomery who assert that he sometimes failed to attain the maximum must at least admit that he never once sustained a major defeat. In this particular instance I went over all details carefully, both with Montgomery and with Alexander. I believed then, and believe now, that a headlong attack against the Mount Etna position, with the resources available in the middle of July, would have been defeated. And it is well to remember that caution and timidity are not synonymous, just as boldness and rashness are not!"
