Ewell had several possible reasons for not attacking. The orders from Lee contained an innate contradiction. He was "to carry the hill occupied by the enemy, if he found it practicable, but to avoid a general engagement until the arrival of the other divisions of the army." Lee also refused to provide assistance that Ewell requested from the corps of A. P. Hill. Ewell's men were fatigued from their lengthy marching and strenuous battle in the hot July afternoon and it would be difficult to reassemble them into battle formation and assault the hill through the narrow corridors afforded by the streets of Gettysburg. The fresh division under Maj. Gen. Edward "Allegheny" Johnson was just arriving, but Ewell also received intelligence that heavy Union reinforcements were arriving on the York Pike from the east, potentially threatening his flank. Ewell's normally aggressive subordinate, Maj. Gen. Jubal A. Early, concurred with his decision.
