It was on precisely such a specious basis of definite misinformation that General McClellan's next proposal for the campaign by way of the Peninsula rested,--precise facts before he sets out turning to something like precise no-facts when he gets there,--beautiful completeness of conception ending in hesitation, confusion, and failure. Before starting, "the roads are passable at all seasons of the year, the country much more favorable for offensive operations than that in front of Washington, much more level, the woods less dense, the soil more sandy" (p. 47). After arriving, we find "the roads impassable," "very dense and extensive forests, the clearings being small and few;" and "the comparative flatness of the country and the alertness of the enemy, everywhere in force, rendered thorough reconnoissances slow, dangerous, and difficult" (p. 79). General McClellan's mental constitution would seem to be one of those, easily elated and easily depressed, that exaggerate distant advantages and dangers near at hand,--minds stronger in conception than perception, and accordingly, as such always are, wanting that faculty of swift decision which, catching inspiration from danger, makes opportunity success. Add to this a kind of adhesiveness (we can hardly call it obstinacy or pertinacity) of temper, which can make no allowance for change of circumstances, and we think we have a tolerably clear notion of the causes of General McClellan's disasters. He can compose a good campaign beforehand, but he cannot improvise one out of the events of the moment, as is the wont of great generals. Occasion seldom offers her forelock twice to the grasp of the same man, and yet General McClellan, by the admission of the Rebels themselves, had Richmond at his mercy more than once.
