The problem presented to Meade's mind, on taking command, was this: What are the enemy's plans, and where shall I strike him? He knew that part of Lee's army was at Chambersburg, part at Carlisle, and part at York. Was it Lee's purpose to concentrate his army upon the detachment at York or upon that at Carlisle, or would he draw these two detachments back into the Cumberland Valley, there to play a merely defensive game? Should the junction be at Carlisle, it would mean an attack on Harrisburg: if at York, or at some point between the main body and York, it would indicate an advance in force toward Philadelphia, Baltimore, or Washington. As all these things were possible, all must be duly weighed and guarded against. With a wily, brave, and confident enemy before him, Meade did not find himself on a bed of roses, truly; and he may well be pardoned the remark attributed to him when ordered to take the command, that he was being led to execution. Meade needed no soothsayer to tell him that if Lee crossed the mountains, it would be because he meant to fight his way toward his object through every obstacle. What was that object? In answering this question the political considerations must be first weighed. In short, the purpose--the great purpose--of the invasion must be penetrated. That being done, the military problem would easily solve itself. It was not to be supposed that Lee had invaded Pennsylvania solely for the purpose of taking a few small towns, or even a large one, like Harrisburg, or of filling up his depleted magazines. He was evidently after larger game. His ultimate aim, clearly, was to capture Washington, as a signal defeat of the Union army would easily enable him to do. It would crown the campaign brilliantly, would fulfil the hopes, and beyond doubt or cavil ensure the triumph, of the Confederacy. It is true that Meade's orders held him down to a defence of the national capital first and foremost; in no sense, then, was he the master of his own acts: yet he showed none the less sagacity, we think, in concluding that Lee would presently be found on the east side of the mountains, and in preparing to meet him there, not astride the mountains as Hooker had proposed doing, but with his whole army more within his reach. Meade was prudent. He would err, if at all, on that side; yet the result vindicated his judgment sooner than was thought for. This being settled, there still remained the question of relieving Pennsylvania. The enemy's presence there was an indignity keenly enough felt on all sides, but to none was it such a home-thrust as to the Pennsylvanians in the Union army, at the head of whom was Meade himself.[25] [Sidenote: Meade's Plans.]
