Lt. Gen. Longstreet took charge of the Department of Virginia and North Carolina on February 25 and initiated his Tidewater Operations. He directed Maj. Gen.D.H. Hill, commander of the North Carolina District, to advance on the Union stronghold of New Bern with about 12,000 men. Maj. Gen. William H. C. Whiting, who commanded the Wilmington garrison, refused to cooperate. After initial success at Deep Gully on March 13, Hill sent Brig. Gen. J. Johnston Pettigrew against the well-entrenched Federals at Fort Anderson on March 14–15, the opposite side of the river from New Bern. Pettigrew was forced to retire upon the arrival of Union gunboats. The city's garrison was heavily reinforced, and Hill withdrew to threaten Washington, North Carolina.
After Gen. Pettigrew’s withdrawal, General Hill was forced to remove his troops from New Bern and head to Washington, NC. The mission was not a complete failure; General Hill was able to fill wagons with food supplies for the troops from areas that were not guarded by Union forces.[4]
