Lee of perhaps over 10,000--from Grant's point of view something gained. Then followed a further movement to the left to out-flank Lee. Again Lee was to be found in the way in a chosen position of his own near Spottsylvania Court House. Here on the five days from May 8 to May 12 the heavy fighting was continued, with a total loss to Grant of over 18,000 and probably a proportionate loss to Lee. Another move by Grant to the left now caused Lee to fall back to a position beyond the North Anna River, on which an attack was made but speedily given up. Further movements in the same general direction, but without any such serious fighting--Grant still endeavouring to turn Lee's right, Lee still moving so as to cover Richmond--brought Grant by the end of the month to Cold Harbour, some ten miles east by north of Richmond, close upon the scene of McClellan's misadventures. Meanwhile Grant had caused an expedition under General Butler to go by sea up the James, and to land a little south of Richmond, which, with the connected fortress of Petersburg, twenty-two miles to the south of it, had only a weak garrison left. Butler was a man with remarkable powers of self-advertisement; he had now a very good chance of taking Petersburg, but his expedition failed totally. From June 1 to June 3 Grant was occupied on the most disastrous enterprise of his career, a hopeless attack upon a strong entrenched position, which, with the lesser encounters that took place within the next few days, cost the North 14,000 men, against a loss to the South which has been put as low as 1,700. It was the one battle which Grant regretted having fought. He gave up the hope of a fight with Lee on advantageous conditions outside Richmond. On June 12 he suddenly moved his army across the James to the neighbourhood of City Point, east of Petersburg. Lee must now stand siege in Richmond and Petersburg. Had he now marched north against Washington, Grant would have been after him and would have secured for his vastly larger force the battle in the open which he had so far vainly sought. Yet another disappointment followed. On July 30 an attempt was made to carry Petersburg by assault immediately after the explosion of an enormous mine. It failed with heavy loss, through the fault of the amiable but injudicious Burnside, who now passed into civil life, and of the officers under him. The siege was to be a long affair. In reality, for all the disappointment, and in spite of Grant's confessed mistake at Cold Harbour, his grim plan was progressing. The force which the South could ill spare was being worn down, and Grant was in a position in which, though he might have got there at less cost, and though the end would not be yet, the end was sure. His army was for the time a good deal shaken, and the estimation in which the West Point officers held him sank low. His own determination was quite unshaken, and, though Lincoln hinted somewhat mildly that these enormous losses
