By the morning of December 30, Sherman had concluded that resuming the attacks at the same location would be fruitless and he and Porter planned a joint army-navy attack on Drumgould's Bluff to the northeast, hoping that the steep bluffs would provide cover for his men as they advanced.
Om morgenen den 30. december var Sherman nået frem til den konklusion, at det ville være håbløst at genoptage angrebene på det samme sted og han og Porter planlagde et fælles angreb på Drumgoulds Bluff mod nordøst i håb om at de stejle klinter ville yde dækning til soldaterne mens de rykkede frem.
