“The May 5 fighting near the Brock Road intersection had left A. P. Hillâ€™s Confederates not only outnumbered but also disorganized. Hill was not worried, however, because Lee had assured him that General James Longstreetâ€™s First Corps would be on the field by dawn to relieve him. Therefore, when Hillâ€™s two division commanders, Henry Heth and Cadmus Wilcox, came to him that night and asked for permission to awaken the troops and prepare them for the next dayâ€™s fight, Hill refused. It was a critical misjudgment. Longstreet was late, and when Hancock resumed his attacks the next morning, he quickly sent Hillâ€™s men on the retreat.
Here in the clearing near the Tapp farm stood 12 guns of Confederate Lieutenant Colonel William Poagueâ€™s artillery battalion. As Hancockâ€™s men pursued Hillâ€™s Confederates into this field, Poague emptied his guns, driving the Federals back into the woods. But Union soldiers soon infiltrated the woods south of the road and began picking off Poagueâ€™s gunners. Hill, who had once served in the artillery, hurried to help with the guns, but still the battalion threatened to give way. Just then, fresh gray-clad troops appeared on the field. It was General John Greggâ€™s Texas Brigade, part of Longstreetâ€™s corps. When Lee discovered the brigadeâ€™s identity, he is said to have shouted, “Hurrah for Texas! Hurrah for Texas!”
Forming a hasty battle line, Greggâ€™s men began moving steadily across the field. Part way across, Lee joined them and appeared intent on leading the charge. But the Texans would not allow it. With shouts of “Lee to the rear!” they turned their commander back. The brigade then swept ahead into the opposite woods, checking the Federals and giving Longstreet time to bring up the rest of his corps.”
