Pope's forces had been considerably cut up and scattered, but he got them together that night, re-formed his lines, and prepared to renew the attack the next day. Lee at the same time drew back his left somewhat, advanced and strengthened his right, and prepared to take the offensive. Each intended to attack the other's left flank.

When Pope moved out the next day (August 30th) to strike Lee's left, and found it withdrawn, he imagined that the enemy was in retreat, and immediately ordered McDowell to follow it up and "press the enemy vigorously the whole day." Porter's corps—the advance of McDowell's force—had no sooner begun this movement than it struck the foe in a strong position, and was subjected to a heavy artillery fire. Then a cloud of dust was seen to the south, and it was evident that Lee was pushing a force around on the flank. McDowell sent Reynolds to meet and check it. Porter then attempted to obey his orders. He advanced against Jackson's right in charge after charge, but was met by a fire that repelled him every time with bloody loss. Moreover, Longstreet found an eminence that commanded a part of his line, promptly took advantage of it by placing a battery there, and threw in an enfilading fire. It was impossible for anything to withstand this, and Porter's corps in a few minutes fell back defeated. The whole Confederate line was advanced, and an attempt was made, by still further extending their right, to cut off retreat; but key-points were firmly held by Warren's brigade and the brigades of Meade and Seymour, and the army was withdrawn in order from the field whence it had retired so precipitously a year before. After dark it crossed the stone bridge over Bull Run, and encamped on the heights around Centreville.

The corps of Sumner and Franklin here joined Pope, and the whole army fell back still further, taking a position around Fairfax Court House and Germantown. Lee meanwhile ordered Jackson to make another of the flank marches that he was so fond of, with a view of striking Pope's right and perhaps interrupting his communication with Washington. It was the evening of September 1st when he fell heavily upon Pope's flank. He was stoutly resisted, and finally repelled by the commands of Hooker and Reno, and a part of those of McDowell and Kearny. General Stevens, of Reno's corps, was killed, and his men, having used up their ammunition, fell back. General Kearny sent Birney's brigade into the gap, and brought up a battery. He then rode forward to reconnoitre, came suddenly upon a squad of Confederates, and in attempting to ride away was shot dead. Kearny was one of the most experienced and efficient soldiers in the service. He had lost an arm in the Mexican war, was with Napoleon III. at Solferino and Magenta, and had just passed through the peninsula campaign with McClellan.

Lee made no further attempt upon Pope's army, and on September 2d, by Halleck's orders, it was withdrawn to the fortifications of Washington, where it was merged in the Army of the Potomac. In this campaign, both the numbers engaged on either side and the respective losses are in dispute, and the exact truth never will be known. Lee claimed that he had captured nine thousand prisoners and thirty guns, and it is probable that Pope's total loss numbered at least fifteen thousand. Pope maintained that he would have won the battle of Groveton and made a successful campaign if General Porter had obeyed his orders. Porter, for this supposed disobedience, was court-martialed in January, 1863, and was condemned and dismissed from the service, and forever disqualified from holding any office of trust or profit under the Government of the United States. Thousands of pages have been written and printed to prove or disprove his innocence, and the evidence has been reviewed again and again. It appears to be established at last that he did not disobey any order that it was possible for him to obey, and that he was blameless—except, perhaps, in having exhibited a spirit of personal hostility to General Pope, who was then his superior officer. A bill to relieve him of the penalty was passed by the Forty-sixth Congress, but was vetoed by President Arthur. Substantially the same bill was passed in 1886 and was signed by President Cleveland. It restored him to his place as colonel in the regular army, and retired him with that rank, but with no compensation for the intervening years.

General Grant, reviewing the case in 1882, came to the conclusion that Porter was innocent, and gave his reasons for it in a magazine article, significantly remarking that "if he was guilty, the punishment awarded was not commensurate with the offence committed." But some other military authorities still believe that his sentence was just. Grant seems to make the question perfectly clear by drawing two simple diagrams. This, he says, is what Pope supposed to be the position of the armies when he ordered Porter to attack:
