About 15 minutes thereafter, Gibbon's XXIV Corps advanced toward the Church Road line and Forts Gregg and Whitworth. An immediate attack by the lead brigade from Brigadier General Robert S. Foster's division under the command of Colonel (Brevet Brigadier General) Thomas O. Osborn recaptured the line and two cannons. The defenders from Lane's and Thomas's brigades in the newly formed line and the Mississippi brigade of Brigadier General Nathaniel H. Harris, who had moved in front of the forts, retreated toward Forts Gregg and Whitworth. Osborn's brigade had reversed the minor setback in the Union advance without loss of life. Gibbon continued to advance the XXIV Corps toward the Appomattox River near the Whitworth house.
