Gibbs' Brigade fell back from the Boisseau farm to a point 1/2 mile north of here, where it was joined by Colonel J. Irvin Gregg's cavalry brigade. Gibbs and Gregg struck Pickett's flank, causing him to wheel into position to meet the new threat. David Johnston of the 7th Virginia recalled the Confederate advance across these fields toward the Adams farm, where, as the last rays of the sun disappeared, the charge began and in less than ten minutes the Confederates gained the summit the enemy had held moments before, driving him into retreat under rapid volleys and leaving the ground thick with dead and wounded. Here was heard the last Rebel yell of the war. A Union cavalryman in Gibbs' Brigade marveled that the Confederate infantry seemed utterly reckless of death, swooping across an open field under severe fire with a careless swing. Union forces suffered heavy casualties and fell back toward Dinwiddie Court House to the protection of Major General George Custer's Division, whose troopers had been brought up from guarding the supply trains and were hurriedly building a defensive line with fence rails and earth. Fitzhugh Lee's cavalry, supported by artillery, stretched to a wider front, outflanked the Union cavalry at Fitzgerald's Ford, forced Smith back from their entrenchments, and gained passage at the crossing. The Federals contested the ground fiercely but were driven step by step a mile back to Adams Road, where they joined Custer.
