The capture of Vicksburg and Port Hudson was a success such as had not been achieved before during our Civil War, and was not paralleled afterward until Appomattox. In military history there are few achievements which equal it; and the magnitude of the captures of men and resources is no more remarkable than are the unfailing courage of the soldiers and the genius and vigor of the general.[242] XIX GETTYSBURG, JULY 1–3, 1863 In the Eastern field of operations in the American Civil War, McClellan’s organization of the Army of the Potomac had given him a well-disciplined force, with which he was facing General Joseph Johnston at the opening of 1862. But the Peninsular Campaign which McClellan entered upon early in the year, with the bloody fighting at Fair Oaks in May, and the Seven Days’ Battles in May and June, resulted in the withdrawal of the Northern forces. There followed Pope’s defeat near Bull Run. The forward movement was a failure. The Northern forces, only four miles from Richmond in June, were practically defending Washington in September. The desperate battle of Antietam checked Lee’s movement into Maryland, but was not decisive. Burnside’s costly defeat at Fredericksburg in December closed a gloomy year in the East, which to many seemed to show that the South could more than hold its own. The new year brought a renewal of disaster to the Northern arms in Hooker’s defeat in the hard-fought battle of Chancellorsville. But the tide was to be turned by one of the crucial events of military history, which was close at hand.--EDITOR. The fall of Vicksburg, though a terrible blow to the South, was not a sudden one: to all intelligent eyes it had for some weeks been impending; but that Lee could be defeated seemed a thing impossible. Because so long unconquered, it had come to be accepted that he was unconquerable. Hooker soon recovered from the daze into which he had been thrown at Chancellorsville. His confidence in himself was not broken by his misfortune. Instead of, like Burnside, manfully shouldering most of the responsibility of his failure, Hooker vehemently accused his lieutenants of misconduct, and faced the new situation with as much resolution as if he had the prestige of a victor. The Army of the Potomac, never down in heart except for a moment, plucked up courage forthwith and girded itself for new encounters.
