Maj. Gen. Winfield Scott Hancock, USA
Maj. Gen. Charles Field, CSA
Each side had a reinforced corps.
Total casualties were around 4,600.
During the night of August 13-14, the Union II Corps, X Corps, and Gregg's cavalry division, all under Hancock's command, crossed the James River at Deep Bottom to threaten Richmond. This was paired with a movement against the Weldon Railroad west of Petersburg; Grant was swinging left and right punches at the same time.
On August 14, the X Corps closed on New Market Heights while the II Corps extended the Federal line to the right along Bailey's Creek. During the night, the X Corps was moved to the far right flank of the Union line near Fussell's Mill. On August 16, Union assaults near Fussell's Mill were initially successful, but Confederate counterattacks drove the Federals out of a line of captured works. Heavy fighting continued throughout the remainder of the day without the Union gaining any advantage ' so victory went to the defender. After continual skirmishing, the Federals returned to the south side of the James on the 20th, maintaining their bridgehead at Deep Bottom.
