Events have succeeded one another with disastrous rapidity. One brief month ago we were apparently at the point of success. Lee was in Pennsylvania, threatening Harrisburgh, and even Philadelphia. Vicksburgh seemed to laugh all Grant’s efforts to scorn. . . . Port Hudson had beaten off Banks’ force. . . . Now the picture is just as sombre as it was bright then. . . . It seems incredible that human power could effect such a change in so brief a space. Yesterday we rode on the pinnacle of success—today absolute ruin seems to be our portion. The Confederacy totters to its destruction.
