General Grant was a man of skill and genius in the game of war. But until the summer of 1864 he had never played that game against another great master of it. He had baffled and beaten Albert Sydney Johnston, whose reputation as a commander of great skill rests rather upon the anticipation of his comrades in the old army at the outbreak of the war, than upon any demonstration of such skill made by himself. Grant had held his own and more against Beauregard in the tremendous second day's struggle at Shiloh. He had overcome great natural obstacles in his effort to take Vicksburg and he had received there the surrender of Pemberton,--a general who had never before commanded an army in the field, or in any other way manifested a capacity for command. Grant had also met Bragg at Chattanooga and beaten him. But none of these antagonists had been comparable with Lee as a great master of strategy and command. When Grant found himself defeated at Cold Harbor, as he has himself described his situation, he had been baffled in both the purposes with which he had undertaken his campaign. He had not crushed Lee's army, nor had he succeeded in cutting it off from its base in the fortifications of Richmond. He had said at Spottsylvania that he would "fight it out on this line if it takes all summer." The summer was still young when he found himself at Cold Harbor unable to do further fighting upon that line. He had crippled his enemy, it is true, but he had lost more than three men to that enemy's one, and that enemy still lay between him and Richmond in a mood of resoluteness and defiance. There was no way open to him by which, with any show of sanity, to assail Lee further in the field. It was then that he decided upon a campaign on other lines than those which he had chosen at the beginning of the summer. He hoped by his movement upon Petersburg to take Lee at last by surprise, to cut his communications, and compel his precipitate retreat from the Confederate capital. Here again he was baffled of his purpose. There remained to him only the resource of dogged determination. He called for reinforcements in order that his army might always outnumber that of his adversary by two or three to one, and thus equipped with superior force, he determined, by continually extending his lines to the south and west, to draw Lee's slender line of defense into the condition of an attenuated thread. Let us make this military situation clear to the minds of unmilitary readers. Grant lay east of Richmond and Petersburg, with a secure base of supplies at City Point on the James river, just in his rear. That base was perfectly protected by a great war fleet which lay in the river and held it. It was easily accessible from the North by transports of every kind, bringing troops or supplies of food or ammunition. Grant's rear was as secure and as well furnished as if it had rested upon New York harbor.
