north of the Chickahominy River. Around 1:00 p.m., Hill, now strengthened by the arrival of Richard Anderson's brigade, hit the secondary Union line near Seven Pines, which was manned by the remnants of Casey's division, the IV Corps division of Brig. Gen. Darius N. Couch, and Brig. Gen. Philip Kearny's division from Heintzelman's III Corps. Hill organized a flanking maneuver, sending four regiments under Col. Micah Jenkins from Longstreet's command to attack Keyes's right flank. The attack collapsed the Federal line back to the Williamsburg Road, a mile and a half beyond Seven Pines. Meanwhile, another of Longstreet's brigades under Col. James L. Kemper, arrived on the field and charged the Union lines, but artillery fire forced them to retreat. The fighting in that part of the line died out by 7:30 p.m. During the evening, Longstreet himself arrived on the field along with the remaining four brigades of his division, as well as the three brigades of Huger's division. On the Union side, Brig. Gen Israel Richardson's division of the II Corps arrived on the field, along with Joe Hooker's division of the III Corps (minus one brigade and the division artillery which were left guarding the bridges over White Oak Swamp). Just before Hill's attack began, Johnston received a note at approximately 4:00 pm from Longstreet requesting that he join the battle, the first news he had heard of the fighting. Johnston went forward on the Nine Mile Road, with a five brigade division led by Brig. Gen. William Chase Whiting. Hours earlier that day, Whiting had been elevated into command of Maj. Gen. Gustavus Smith's division. As the lead regiment of the division, led by Col. Dorsey Pender, 6th NC, reached the railroad crossing artillery guns opened on Pender's advance. This opened the segment of the Battle of Seven Pines to be known as the Battle of Fair Oaks Station. The guns were a part of Brig. Gen John Abercrombie's brigade of Couch's division and they began to put up a stiff resistance. Whiting advanced his former brigade, commanded by Col. Evander Law, to attack the Union artillery off to his left, but was stopped by Abercrombie's brigade and his four artillery pieces. Meanwhile, the commander of the II Corps, Brig. Gen Edwin V. Sumner, had brought his command into action from its entrenchments north of the Chickahominy. When told that crossing the rain-swollen river was impossible,
