Arrival of Lee.
General Lee reached the field from Cashtown about 3 P.M., witnessed the retreat of the Union forces, and established his headquarters in tents in an apple orchard back of the Seminary. He ordered Ewell to follow up the repulse if he thought it practicable. In this connection Ewell reported:
“The enemy had fallen back to a commanding position known as Cemetery Hill, south of Gettysburg, and quickly showed a formidable front there. On entering the town, I received a message from the Commanding General to attack this hill, if I could do so to advantage. I could not bring artillery to bear on it, and all the troops with me were jaded by twelve hours’ marching and fighting, and I was notified that General Johnson’s division (the only one of my corps that had not been engaged) was close to town. Cemetery Hill was not assailable from the town.... Before Johnson could be placed in position the night was far advanced.”
John Burns, Gettysburg constable and Mexican War veteran, shouldered his musket and went out to meet the Confederates.
General Hill reported:
“Under the impression that the enemy was entirely routed, my own two divisions exhausted by some six hours’ hard fighting, prudence led me to be content with what had been gained.”
The failure of Ewell to follow up the repulse and capture Cemetery Hill and Culp’s Hill, defended by a weak line of the Union forces, enabled the Union commanders to establish during the night a line of defence that was secure against attack. By many military critics, this is generally considered Lee’s lost opportunity.
