I suppose it will be taking as nitpicking, but I'm going to say it anyway: The battle of Gettysburg began on July 1, not June 30.
But more usefully, I quote the following from the reports of General Rodes and Early.
From General Rodes ( http://www.civilwarhome.com/rodesgettysburg.html );
The enemy was thus routed at all points. My division followed him closely into and through the town, Doles and Ramseur entering in such close contact with the enemy that the former, who penetrated the heart of the town first of all, had two sharp and successful encounters with the enemy in its streets, and the latter, who entered farther to the right, captured the colors of the One hundred and fiftieth Pennsylvania Regiment in its streets, Lieutenant [F. M.] Harney, of his brigade, tearing them from the hands of the color-bearer, and falling almost immediately thereafter, mortally wounded.
In the pursuit, the division captured about 2,500 prisoners--so many as to embarrass its movements materially.
The troops, being greatly exhausted by their march and somewhat disorganized by the hot engagement and rapid pursuit, were halted and prepared for further action. I did not change their position materially, nor order another attack, for the following reasons: 1st, in the midst of the engagement just described, the corps commander informed me, through one of his officers, that the general commanding did not wish a general engagement brought on, and hence, had it been possible to do so then, I would have stopped the attack at once; but this, of course, it was impossible to do then; 2d,
before the completion of his defeat before the town, the enemy had begun to establish a line of battle on the heights back of the town, and by the time my line was in a condition to renew the attack, he displayed quite a formidable line of infantry and artillery immediately in my front, extending smartly to my right, and as far as I could see to my left, in front of Early. To have attacked this line with my division alone, diminished as it had been by a loss of 2,500 men, would have been absurd. Seeing no Confederate troops at all on my right; finding that General Early, whom I encountered in the streets of the town within thirty minutes after its occupation by our forces, was awaiting further instructions, and, receiving no orders to advance, though my superiors were upon the ground, I concluded that the order not to bring on a general engagement was still in force, and hence placed my lines and skirmishers in a defensive attitude, and determined to await orders or further movements either on the part of Early or of the troops on my right.
And from General Early ( http://www.civilwarhome.com/earlygettysburg.html ):
Hays' brigade entered the town, fighting its way, and Avery moved to the left of it across the railroad, and took his position in the fields on the left, and facing Cemetery Hill, which here presented a very rugged ascent. This movement was made under the fire of artillery from this hill, which had previously opened when my artillery had first opened its fire, but Avery succeeded in placing his men under the cover of a low ridge which here runs through the fields from the town. Hays' brigade was formed in line in the street running through the middle of the town.
A very large number of prisoners were captured in the town, and before reaching it, their number being so great as really to embarrass us. Two pieces of artillery (Napoleons) were also captured outside of the town, the capture being claimed by both brigades; but it is unnecessary to decide which reached these pieces first, as the capture was unquestionably due to the joint valor of both brigades.
While these operations were going on with my division, I saw, farther to the right, the enemy's force on that part of the line falling back and moving in comparatively good order on the right of the town toward the range of hills in the rear, and I sent back for a battery of artillery to be brought up to open on this force and the town, from which a fire was opened on my brigades, but before it got up, my men had entered the town, and the force on the right had retired beyond reach. I had at the same time sent an order to General Smith to advance with his brigade, but he thought proper not to comply with this order, on account of a report that the enemy was advancing on the York road.
As soon as my brigades had entered the town, I rode into that place myself, and, after ascertaining the condition of things, I rode to find General Ewell and General Rodes, or General Hill, for the purpose of urging an immediate advance upon the enemy before he should recover from his evident dismay, in order to get possession of the hills to which he had fallen back with the remnant of iris forces; but before I found either of these officers, General Smith's son, who was acting as his aide, came to me with a message from the general, stating that a large force of the enemy, consisting of infantry, artillery, and cavalry, was advancing on the York road, and that we were about to be flanked: and though I had no faith in this report,
I thought proper to send General Gordon with his brigade to take charge of Smith's also, and to keep a lookout on the York road, and stop any further alarm.
Meeting with an officer of Major-General Pender's staff, I sent word by him to General Hill that if he would send up a division, we could take the hill to which the enemy had retreated; and shortly after meeting with General Ewell, I communicated my views to him, and was informed that Johnson's division was coming up, and it was determined with this division to get possession of a wooded hill to the left of Cemetery Hill, which it commanded; but this division arrived at a late hour, and its movement having been delayed by the report of the advance on the York road, no effort to get possession of the wooded hill on the left of the town was made that night.
Bolding is mine, but the words are all theirs.
