The first counter-invasion naturally followed. Southern hopes ran high. Bragg's invasion of Kentucky seemed to be succeeding at this time. The trans-Mississippi line still held at Vicksburg and Port Hudson. Richmond had been saved. Washington was menaced. And most people on both sides thought so much more of the land than of the sea that the Federal victories along the coast and up the Mississippi were half forgotten for the time being; and so was the strangling blockade. Lee, of course, saw the situation as a whole; and, as a whole, it was far from bright. But though the counter-invasion was now a year too late it seemed worth making. Maryland was full of Southern sympathizers; and campaigning there would give Virginia a chance to recuperate, while also preventing the North from recovering too quickly from its last reverse. Thus it was with great expectations that the Confederates crossed the Potomac singing _Maryland, my Maryland!_ But Maryland did not respond to this appeal. The women, it is true, were mostly Southern to the core and ready to serve the Confederate cause in every way they could. But the men, reflecting more, knew they were in the grip of Northern sea-power. Nor could they fail to notice the vast difference between the warlike resources of the North and South. Northern armies had been marching through for many months, well fed, well armed, and superabundantly supplied. The Confederates, on the other hand, were fewer in numbers, half starved, in ragged clothing, less well armed, and far less abundantly supplied in every way. A Northerner who fell sick could generally count on the best of medical care, not to mention a profusion of medical comforts. But the blockade kept medicines and surgical instruments out of the Southern ports; and the South could make few of her own. So, to be very sick or badly wounded meant almost a sentence of death in the South. Eighteen months of war had disillusioned Maryland. The expected reinforcements never came. Lee had again divided his army in the hope of snatching victory by means of better strategy. On the thirteenth of September Jackson was bombarding the Federals at Harper's Ferry, Longstreet was at Hagerstown, and Stuart was holding the gaps of South Mountain.
