The will for victory which gives a commander the strength to see a grave crisis through is something very different from Hitler's will, which in the last analysis stemmed from a belief in his own 'mission'. Such a belief makes a man impervious to reason and leads him to think that his own will can operate even beyond the limits of hard reality - whether these consist in the presence of far superior enemy forces, in the conditions of space and time, or merely in the fact that the enemy also happens to have a will of his own.
