Through all those long hours of conflict, there was patient endurance in front of the enemy. There were temporary successes and reverses on both sides. In only a single instance was there permanent advantage to the enemy, and that he had not the power to improve. It was at the close of the contest on the 6th. The sun had gone down, and twilight was deepening into night. The wearied men of Rickett's division of the Sixth Corps, in the front line of battle on the right, had thrown themselves upon the ground. Suddenly there was a rush upon their flank. There was musketry, blinding flashes from cannon, and explosions of shells. The line which had stood firmly through the day gave way, not because it was overpowered, but because it was surprised. General Seymour and a portion of his brigade were taken prisoners. There was a partial panic, which soon subsided. The second line remained firm, the enemy was driven back, and the disaster repaired by swinging the Sixth Corps round to a new position, covered by the reserve artillery. It was the only substantial advantage gained by Lee during the battle. There were indications in the forenoon of Saturday, the 7th, that Lee was withdrawing his army. A reconnoissance in force made it more apparent. Orders were issued for the removal of the wounded to Fredericksburg. At two o'clock in the afternoon the Ninth Corps was on the march to Spottsylvania. The first step towards Richmond had been successfully taken. If Grant had not gained what he desired, a position between Lee and Richmond, Lee on the other hand had utterly failed in his attempt to crush Grant by a sudden blow upon his flank. He had not been able, in the language of the President, even to "jostle him from his chosen line of march." SPOTTSYLVANIA. At sunrise on the 8th, the Fifth Corps was at Todd's Tavern, four miles from Spottsylvania, where Gregg had just defeated Fitz Hugh Lee, in a hard-fought contest on Saturday. The Sixth and Second Corps arrived during the day. The Ninth moved with the teams through Chancellorsville farther to the east. The natural defences of Spottsylvania are two small streams,--the Po and the Ny, affluents of the Mattapony. The advance of the Fifth Corps was checked, three miles west of the Court-House, by Longstreet's and Ewell's corps, which had left Wilderness on the night of the 6th. The Sixth came up at five o'clock and joined in the conflict, driving the enemy from the position he had taken on the north bank of the Ny. On Monday morning, the 9th, it was apparent that Lee, having failed on Grant's flank, had now placed himself squarely in front, with his entire army. One of the great battles of the campaign was fought on Tuesday, the corps occupying positions as in the diagram:-- [Illustration:
