 Lee received notice that reinforcements were heading Grant's way from Bermuda Hundred.The 16,000 men of Maj. Gen. William F. "Baldy" Smith's XVIII Corps were withdrawn from Maj. Gen. Benjamin Butler's Army of the James at Grant's request, and they were moving down the James River and up the York to the Pamunkey.If Smith moved due west from White House Landing to Old Cold Harbor, southeast of Bethesda Church and Grant's left flank, the extended Federal line would be too far south for the Confederate right to contain.
