Noon passed. One o'clock came round. "Longstreet is joining Jackson," was the word from the pickets. The attack must be made at once if ever.

It began at two o'clock by Hooker and Kearny on the right, pushing through the woods and across the fields between Dogan's house and Sudley Church.[50]

The veterans of the Peninsula move upon an enemy whom they have met before. Jackson has made the line of a half-finished railroad his defense, and his men are behind the embankments and in the excavations. It is a long, desperate conflict. There are charges upon the enemy's lines and repulses. Three,—four,—five o'clock, and Porter has not come. McDowell, who should have marched northwest to Groveton to meet Longstreet, has, through some mistake, marched east of that place, and joined the line where Kearny and Hooker are driving Jackson.

At this hour, sunset, on August 29th, Kearny, Hooker, and Reno are pushing west, north of the turnpike, close upon the heels of Jackson. King's division of McDowell's corps is moving west along the turnpike past Dogan's house, to attack what has been Jackson's right center, but which is now the left center of the united forces of Jackson and Longstreet. Sigel's brigades have been shattered, and are merely holding their ground south of the turnpike. O, if Porter with his twelve thousand fresh troops was only there to fall on Jackson's right flank! But he is not in sight. Nothing has been heard from him. He has had all day to march five miles over an unobstructed road. He has had his imperative orders,—has heard the roar of battle. He is an officer in the Regular service, and knows that it is the first requisite of an officer or a soldier to obey orders.

Battle of Groveton.

1 Hooker. 2 Kearny. 3 Reno. 4 Porter. 5 McDowell. 6 Sigel. A Rebel left wing, commanded by Jackson. B Rebel right wing, commanded by Longstreet. C Stone Bridge. D Dogan's House. RR Unfinished Railroad.

Longstreet is too late upon the ground to make an attack with his whole force. The sun goes down and darkness comes on. The contest for the day is over. Jackson has been driven on his right, and Heintzelman's corps holds the ground. Both armies sleep on their arms.

The auspicious moment for crushing Jackson had passed. The most that Pope could hope for was to hold his ground till Franklin and Sumner, who had landed at Alexandria, could join him. Thus far the battle had been in his favor. He wished to save his wagons which were at Manassas. If he retreated across Bull Run and made that his line of defense, he must abandon his trains at Manassas. If he did this, Banks would be cut off. He hoped, with Porter's magnificent corps holding his left flank, to defeat Lee.
