mind, no man could change it, and here, as ill fortune would have it, he had made it up. So, with a heavy heart, the reluctant McDowell set forth on his foolish errand, and Fremont likewise came upon his,--though it is true that he was better employed thus than in doing nothing,--and Jackson, highly pleased, and calculating his time to a nicety, on May 31 slipped rapidly between the two Union generals,--the closing jaws of Mr. Lincoln's "trap,"--and left them to close upon nothing.[21] Then he led his pursuers a fruitless chase towards the head of the valley, continuing to neutralize a force many times larger than his own, and which could and ought to have been at this very time doing fatal work against the Confederacy. Presumably he had saved Richmond, and therewith also, not impossibly, the chief army of the South. The chagrin of the Union commanders, who had in vain explained the situation with entire accuracy, taxes the imagination. There is no use in denying a truth which can be proved. The blunder of Mr. Lincoln is not only undeniable, but it is inexcusable. Possibly for a few hours he feared that Washington was threatened. He telegraphed to McClellan May 25, at two o'clock P.M., that he thought the movement down the valley a "general and concerted one," inconsistent with "the purpose of a very desperate defense of Richmond;" and added, "I think the time is near when you must either attack Richmond, or give up the job and come to the defense of Washington." How reasonable this view was at the moment is of little consequence, for within a few hours afterward the character of Jackson's enterprise as a mere foray became too palpable to be mistaken. Nevertheless, after the President was relieved from such fear for the capital as he might excusably have felt for a very brief period, his cool judgment seemed for once in his life, perhaps for the only time, to be disturbed. The truth is that Mr. Lincoln was a sure and safe, almost an infallible thinker, when he had time given him; but he was not always a quick thinker, and on this occasion he was driven to think quickly. In consequence he not only erred in repudiating the opinions of the best military advisers, but even upon the basis of his own views he made a mistake. The very fact that he was so energetic in the endeavor to "trap" Jackson in retreat indicates his understanding of the truth that Jackson had so small a force that his prompt retreat was a necessity. This being so, he was in the distinct and simple position of making a choice between two alternatives, viz.: either to endeavor to catch Jackson, and for this object to withhold what was needed by and had been promised to McClellan for his campaign against Richmond; or, leaving Jackson to escape with impunity, to pursue with steadiness that plan which it was Jackson's important and perfectly understood errand to interrupt. It is almost incredible that he chose wrong. The statement of the dilemma involved the decision.
