Калпс-Хилл
The Union line ran from Culp's Hill southeast of the town, northwest to Cemetery Hill just south of town, then south for nearly along Cemetery Ridge, terminating just north of Little Round Top. Most of the XII Corps was on Culp's Hill; the remnants of I and XI Corps defended Cemetery Hill; II Corps covered most of the northern half of Cemetery Ridge; and III Corps was ordered to take up a position to its flank. The shape of the Union line is popularly described as a "fishhook" formation.
