On July 2, 1863, on the second day of the Battle of Gettysburg, several units were moved from the Union right flank on Culp's Hill to the south to reinforce the left flank which was being attacked. Seeing an opportunity, Confederate General Richard S. Ewell launched an attack on Culp's Hill and his men occupied the earthworks deserted by the withdrawn units. Attempts were made to retake the fortifications, but due to miscommunications, such attempts were unsuccessful and resulted in heavy Union casualties.
