Patterson had greatly overestimated Johnston's force and feared to make an attack; indeed in his alarm he marched north, directly away from the Confederates instead of following them. Unaware of his actual movement the Confederate generals thought that he would make haste to join McDowell. Beauregard therefore deemed it advisable to attack the Union forces with his right wing and centre before the expected reënforcement came; Johnston, the ranking officer, approved the plan. A miscarriage of orders prevented the movement; at the same time McDowell's attack came as a surprise and it was the sound of cannon that first told them he was trying to turn their left. It was four miles to the scene of action but Johnston and Beauregard rode thither as fast as their horses would carry them. "We came not a moment too soon," said Johnston. The Confederates were demoralized; a disorderly retreat had begun; and it needed all the firmness and courage of the commanding generals to stem the tide. Beauregard remained in the thick of the fight, in command of the troops there engaged, while Johnston rode regretfully to the rear to hurry forward reënforcements.
It was high noon when the two Confederate generals appeared on the field. The battle lasted until three. The hottest fighting was for the possession of the Henry plateau which the Union troops had seized. At two o'clock Beauregard gave the order to advance to recover the plateau. The charge was made with spirit. Jackson's brigade pierced the Union centre at the bayonet's point; the other troops moved forward with equal vigor, broke the Union lines and swept them back from the open ground of the plateau. The Union troops rallied, recovered their ground and drove the Confederates from the plateau into the woods beyond. McDowell, who had this part of the field immediately under his own eye, thought this last repulse final and that the day was his.
Jefferson Davis, too anxious to remain in Richmond, went by rail to the scene of action. As he approached Manassas railroad junction he saw a cloud of dust raised by wagons that had been sent to the rear and heard distinctly the sound of firing. At the junction were a large number of men who had left the field in panic and who now gave Davis graphic accounts of the defeat of the army. He asked a gray-bearded man whose calm face and composed demeanor inspired confidence, how the battle had gone? "Our line was broken," came the reply; "all was confusion, the army routed and the battle lost." The conductor of the train refused to go farther but, on Davis's stern insistence, detached the locomotive and ran it to the headquarters, where Davis found horses for himself and his aide; two officers guided him thence toward the battle-field. On the way, he met a large number of stragglers and received frequent warnings that there was danger ahead; but the sound of firing was now fainter, which seemed to indicate both an advance of the Confederates and a waning of the battle. Meeting Johnston on a hill overlooking the field, he might in his question have used the words of Henry V at Agincourt, "I know not if the day be ours or no?" when Johnston at once assured him, "that we had won the battle."
It was three o'clock when McDowell saw the Confederates retire to the woods, when he hoped that the fight was over and that his army had gained possession of the field. This hope was rudely dispelled. His men had made their last desperate effort. They had been up since two in the morning; one division had had a long fatiguing march. The day was intensely hot and the fight had lasted four and a half hours. Many of the men had thrown away their haversacks and canteens. They were choked with dust, thirsty, hungry and spent. Beauregard ordered forward all of his force within reach, including the reserve, for the purpose of making a last supreme effort to regain the plateau; he intended to lead the charge in person. Then loud cheers were heard proceeding from fresh troops. They were the remainder of the army of the Shenandoah who had followed Johnston as quickly as the railroad could bring them and who were now personally ordered by him to assail McDowell's right flank. From mouth to mouth went the word, "Johnston's army has come." At the same time Beauregard moved forward his whole line. The Union troops "were instantly seized with one of those unaccountable panics to which great armies are liable."96 They broke and ran down the hillside in disorder. McDowell and his officers tried to rally them but the regular infantry alone obeyed commands, covering the volunteers' retreat. They crossed the fords of Bull Run and crowded the Warrenton turnpike, a confused mass of disorganized frightened men. The Confederates pursued them only a short distance;97 and McDowell intended to make a stand at Centreville. That was found to be impossible nor could the disorderly flight be arrested at Fairfax Court-House. "The larger part of the men," telegraphed McDowell from there, "are a confused mob, entirely demoralized. They are pouring through this place in a state of utter disorganization." The flight of the troops was not stopped until they reached the fortifications on the southern side of the Potomac, and many of the soldiers crossed the Long bridge into Washington. All were soon to learn that they had been fleeing before an imaginary foe, as the Confederates made no effective pursuit.
Lincoln in Washington was a prey to the same anxiety as Davis in Richmond. After his return from church, he scanned eagerly the telegrams sent to him from the War Department and from the army headquarters. These despatches were from the telegraphic station nearest the battle-field and toward three o'clock became more frequent and reported the apparent course and progress of the cannonade. Impatient as he was to talk over the news, he repaired to Scott's office, where he found the aged and infirm general taking his afternoon sleep. On being waked Scott told him that such reports as had already been received possessed no value but, expressing his confidence in a successful result, he composed himself for another nap. Despatches continued to come with cheering news. It was reported that the Confederates had been forced back two or three miles. One of Scott's aides brought to the President a despatch from a lieutenant of engineers at Centreville saying that McDowell had driven the enemy before him, ordered the reserve forward and desired reënforcements without delay. As Scott deemed the report credible, the President, thinking all doubt at an end, ordered his carriage for his usual evening drive. At six o'clock Secretary Seward appeared at the White House pale and haggard. " 'Where is the President?' he asked hoarsely of Lincoln's private secretaries. 'Gone to drive,' they answered. 'Have you any late news?' he continued. They read him the telegrams announcing victory. 'Tell no one,' said he. 'That is not true. The battle is lost.… McDowell is in full retreat and calls on General Scott to save the capital.'"98 Returning from his drive a half hour later, the President heard Seward's message, walked over to army headquarters and there read the despatch from a captain of engineers: "General McDowell's army in full retreat through Centreville. The day is lost. Save Washington and the remnants of this army.… The routed troops will not reform." "The President did not go to his bed that night; morning found him still on his lounge in the executive office,"99 listening to the recitals of newspaper correspondents and other civilians, who had followed McDowell to Centreville and, after the repulse, fearing for their own safety, had rushed back to Washington, beginning to arrive at midnight. Monday broke dismally in the capital, a drizzling rain adding to the gloom. But by noon it was known that the Confederates had not pursued the retreating troops in the aim of taking Washington.
The disaster caused some prominent men to lose their nerve; not so, the President. Bitterly disappointed as he was at the result, he from the first showed no discouragement or loss of control. During the week he paid visits to the camps surrounding Washington and in one of these had William T. Sherman for his guide. Sherman, standing by the roadside, was recognized by Lincoln and Seward, "who rode side by side in an open hack" and, on his inquiring if they were going to his camps, he received from Lincoln the reply, "Yes, we heard that you had got over the big scare, and we thought we would come over and see the boys." The President asked Sherman to get into their carriage and direct their course. Sherman perceived his emotion and his desire to speak to the men, so he ventured to utter a word of caution. "Please discourage," he said, "all cheering, noise or any sort of confusion; we had enough of it before Bull Run to ruin any set of men; what we need is cool, thoughtful,
