The winter of 1862-3 is now by common consent regarded as the darkest period of the war for the Union. The failure of Burnside’s plans and the defeat of Hooker at Chancellorsville severely tried the discipline and organization of the Army of the Potomac, and filled the loyal North with alarm, while it correspondingly encouraged the Confederate government and raised the confidence of its army. As soon as the winter was over and the roads were settled Lee assumed the initiative, drove Hooker back from the Rappahannock, crossed the Potomac, advanced confidently to Chambersburg and pushed his cavalry as far north as Harrisburg and York.
Hooker had also proven himself to be incompetent, and desperate as the measure was, the Washington government relieved him in the midst of an active campaign, and entrusted the army and its fortunes to the direction of Major General George G. Meade, a gallant and able soldier, who checked the high tide of rebellion at Gettysburg on the 2nd and 3rd of July, 1863. During this campaign Smith, who was on leave of absence when it began, made haste to offer his services, without conditions, and was at once sent to Harrisburg to assist Major General Couch, who had been assigned to the command of the Pennsylvania and New York militia. Taking command of an improvised division, he moved against the enemy, then threatening Carlisle, with all the assurance of a veteran, and while the prompt retreat of the enemy prevented any severe engagement, the movement was entirely efficacious. With the true instincts of a soldier he pressed on in the direction of the Confederate army, and took part in its pursuit from Gettysburg back to Virginia. Curiously enough, instead of commending and thanking him and his raw troops for their gallant services, the Secretary of War ordered his arrest for taking his command beyond the limits of Pennsylvania, for the special defence of which the militia had been called out, but fortunately the remonstrance of General Couch caused this order to be recalled, and the gallant but unappreciated general again withdrew from the field, as soon as the scare was over and his forces were permitted to return to their homes.
It will be remembered that the news of Lee’s defeat and his retreat from Gettysburg reached the country on the 4th of July, and that the same day was made triply memorable by the capture of Vicksburg with Pemberton’s entire army of 30,000 men with all their guns and ammunitions. These two striking events threw the country into the wildest enthusiasm. Even the most despondent now became confident that the Southern Confederacy would soon be destroyed, and that the triumphant Union would be finally re-established. But this confidence was destined to be rudely shaken.
