Sigel's Corps with Reynold's Division pressed westward and became engaged in a series of disjointed attacks against Jackson's position along the railroad

1000

Sigel called off attacks.

0900-1000

Longstreet's Corps began arriving south of Jackson's line and completed its deployment about 1100. Hood's Division was on both sides of the turnpike near Pageland Lane. Wilcox's Division was echeloned to his left rear, while Kemper's Division was echeloned to his right rear. D. R. Jones' Division extended from Kemper's farther south across the Manassas Gap Railroad and Robertson's Cavalry screened toward Manassas. Jones engaged elements of Morell's Division; Porter's Corps was engaged in desultory fighting all afternoon.

1100

Heintzelman's Corps (Kearny's and Hooker's Divisions) and Reno's Corps (Reno's and Stevens' Divisions) arrived near the Stone House.

1200

The Federal attack was renewed. Schurz's Division seized part of Jackson's railroad position and held it until relieved at 1400 by Heintzelman's Corps.

1400-1500

Period of regrouping and rest with some skirmishing.

1500

Grover's Brigade, Hooker's Division made a successful bayonet attack against the center of Jackson's line; lost 500 men in 20 minutes, was not supported and was forced back.

1700

Kearny attacked on Jackson's extreme left (north) and began to roll up that part of the line held by A. P. Hill's Division. Two brigades of Confederate reinforcements were rushed from an unthreatened portion of their line and repulsed Kearny's men.

1700

Wilcox's Division was shifted by Longstreet to support D. R. Jones toward Manassas; it soon returned when no threat developed. Fitz-John Porter's presence to the south had fixed Longstreet's right wing all afternoon. The Confederate did not want to commit himself until he had determined Porter's intentions.

1730

Hatch's (formerly King's) Division arrived at the Stone House and was ordered to attack westward along the Pike.

1830

Hatch's Division collided with Hood's Division, which was probing eastward along the Warrenton Pike. Fighting endured around Groveton until about 1915. Reynolds' Division south of the Pike had been prevented from supporting effectively by Longstreet's artillery.

c. 1830

Pope ordered Porter to bring his corps to Groveton. Pope felt Jackson was retreating and disregarded Porter's reports of Longstreet's presence south of the Pike. Longstreet was freed for the next day.

1200

Federals began to move into attack positions; Reynolds shifted to Chinn's Ridge.

1500

Butterfield's and Hatch's Divisions with Sykes' in support commenced the main attack. They pushed to the railroad held by Jackson's men but were enfiladed by Longstreet's artillery on their left (south). Meanwhile Heintzelman's units pressed farther north.

1500

Reynolds was pulled from his position to support Porter. Only Warren's Brigade (Sykes' Division) and Anderson's Brigade (Reynolds' Division) remained south of the Pike.

1530

Longstreet attacked, pivoting on Jackson's position. Hood's Division advanced along an axis formed by the Pike while Longstreet's other units advanced in an arc north-northeast.

1600

Warren's position was overrun. Pope placed more troops on Chinn's Ridge: Ricketts', along with Schurz's and parts of Schenck's Division were rushed in; Sykes' Division went to Henry Hill farther east and was joined later by Reynolds with two of his brigades. Reno and Heintzelman delayed north of the Pike against Jackson, who conformed to Longstreet's advance.

1800

Chinn's Ridge was taken. Fighting shifted to Henry Hill. Sykes and Reynolds held until relieved by Stevens' Division of Reno's Corps, which halted the last Confederate attack.

2030

All quiet.

2300

Schurz's Division evacuated a bridgehead west of Stone Bridge.

0100

Turnpike Bridge was blown up; Federals drew into Centreville positions. (The stone bridge had been destroyed 9 March 1862 by Confederates. The bridge destroyed 31 August was a temporary wooden span.)
