After the Confederate breakout attempt, Grant noted a weak point in the Confederate defense line and ordered General C.F. Smith to attack the far right flank of the Southern lines. Smith's troops, facing a largely depleted Confederate position because of Buckner's movement to the Confederate breakout attempt, pushed the stubborn 30th Tennessee Infantry back to this ridge. The valiant defenders held this position until reinforced by Buckner's division and the fort's garrison. Although the position was held by Confederate forces, Smith's division of the Union Army solidly held the Confederate right wing.
