Hatch's expeditionary force left Hilton Head, South Carolina, for Boyd’s Neck (above Beaufort) on November 28. It consisted of 5,000 men—two brigades of the Coast Division of the Department of the South, one naval brigade, and portions of three batteries of light artillery. They steamed up the Broad River in transports to cut the Charleston and Savannah Railroad near Pocotaligo. Due to a heavy fog the troops were not disembarked from the transports until late the following afternoon, and Hatch immediately started forward to cut the railroad near Grahamville.
