Ewell was still ahead.

Finally they came to Chambersburg, which the Southern advance had reached earlier in the month, and Lee issued an order that no devastation should be committed by his troops, an order that was obeyed.
Harry and Dalton walked a little through the town, and menacing looks met them everywhere.
"We've treated 'em well, but they don't like us," he said to Dalton.
"Why should they?
We come as invaders, as foes, not as friends.
Did our people in the Virginia towns give the Yankees any very friendly looks ?" "Not that I've heard of.

I suppose you can't make friends of a people whom you come to make war on, even if you do speak kind words to them." "Is General Stuart here ?" asked Dalton.
"No, he's gone on a great raid with his whole force.

I suppose he's going to sweep up many detachments of the enemy." "And meanwhile we're going on to Harrisburg, the capital of Pennsylvania." "But it seems to me that Stuart ought to be with us." "Maybe he's gone to find out just where the Army of the Potomac is.
We've lost Meade, and Meade has lost us.

Some prisoners that we've brought in say that nobody in the North knows just where our army is, although all know that it's in Pennsylvania." But that night, while Harry was at General Lee's headquarters, a scout arrived with news that the Army of the Potomac was advancing upon an almost parallel line and could throw itself in his rear.
