Four pieces of artillery, several hundred prisoners, and two regimental flags were taken. As soon as the engagement began on our right, General Johnson opened with his artillery, and about two hours later advanced up the hill next to Cemetery Hill with three brigades, the fourth being detained by a demonstration on his left. Soon afterward, General Early attacked Cemetery Hill with two brigades, supported by a third, the fourth having been previously detached. The enemy had greatly increased by earthworks the strength of the positions assailed by Johnson and Early.

The troops of the former moved steadily up the steep and rugged ascent, under a heavy fire, driving the enemy into his entrenchment's, part of which was carried by Stuart's brigade, and a number of prisoners taken. The contest was continued to a late hour, but without further advantage. On Cemetery Hill, the attack by Early's leading brigades -- those of Hays and Hoke under Colonel [I.E.] Avery -- was made with vigor. Two lines of the enemy's infantry were dislodged from the cover of some stone and board fences on the side of the ascent, and driven back into the works on the crest, into which our troops forced their way, and seized several pieces of artillery.

A heavy force advanced against their right which was without support, and they were compelled to retire bringing with them about 100 prisoners and four stand of colors. General Ewell had directed General Rodes to attack in concert with Early, covering his right and had requested Brigadier-General Lane, then commanding Pender's division, to co-operate on the right of Rodes. When the time to attack arrived, General Rodes, not having his troops in position, was unprepared to co-operate with General Early, and before he could get in readiness the latter had been obliged to retire for want of the expected support on his right. General Lane was prepared to give the assistance required of him, and so informed General Rodes, but the latter deemed it useless to advance afte the failure of Early's attack.

In this engagement our loss in men and officers was large. Major-Generals Hood, and Pender, Brigadier-Generals [J.M.] Jones, Semmes, G.T. Anderson, and Barksdale, and Colonel Avery, commanding Hoke's brigade, were wounded, the last two mortally. Generals Pender and Semmes died after their removal to Virginia.

The result of this day's operations induced the belief that, with proper concert of action, and with the increased support that the positions gained on the right would enable the artillery to render the assaulting columns, we should ultimately succeed, and it was accordingly determined to continue the attack. The general plan was unchanged. Longstreet, re-enforced by Pickett's three brigades, which arrived near the battle-field during the afternoon of the 2d, was ordered to attack the next morning, and General Ewell was directed to assail the enemy's right at the same time. The latter, during the night, re- enforced General Johnson with two brigades from Rodes' and one from Early 's division.

General Longstreet's dispositions were not completed as early as was expected, but before notice could be sent to General Ewell, General Johnson had already become engaged, and it was too late to recall him. The enemy attempted to recover the works taken the preceding evening, but was repulsed, and General Johnson attacked in turn.

After a gallant and prolonged struggle, in which the enemy was forced to abandon part of his entrenchment's, General Johnson found himself unable to carry the strongly fortified crest of the hill. The projected attack on the enemy's left not having been made, he was enabled to hold his right with a force largely superior to that of General Johnson and finally to threaten his flank and rear, rendering it necessary for him to retire to his original position about 1 p.m.

General Longstret was delayed by a force occupying the high rocky hills on the enemy's extreme left, from which his troops could be attacked in reverse as they advanced. His operations had been embarrassed the day previously by the same cause, and he now deemed it necessary to defend his flank and rear with the divisions of Hood and McLaws. He was, therefore, re-enforced by Heth's division and two brigades of Pender's, to the command of which Major-General Trimble was assigned. General Hill was directed to hold his line with the rest of his command, afford General Longstreet further assistance, if required, and avail himself of any success that might be gained.

A careful examination was made of the ground secured by Longstreet, and his batteries placed in positions, which it was believed, would enable them to silence those of the enemy. Hill's artillery and part of Ewell's was ordered to open simultaneously, and the assaulting column to advance under cover of the combined fire of the three. The batteries were directed to be pushed forward as the infantry progressed, protect their flanks, and support their attacks closely.

About 1 p.m., at a given signal, a heavy cannonade was opened, and continued for about two hours with marked effect upon the enemy. His batteries replied vigorously at first, but toward the close their fire slackened perceptibly, and General Longstreet ordered forward the column of attack, consisting of Pickett's and Heth's divisions, in two lines, Pickett on the right. Wilcox's brigade, marched in rear of Pickett's right, to guard that flank, and Heth's was supported by Lane's and Scales' brigades' under General Trimble.

The troops moved steadily on, under a heavy fire of musketry and artillery, the main attack being directed against the enemy's left conter.

His batteries reopened as soon as they appeared. Our own having nearly exhausted their ammunition in the protracted cannonade that preceded the advance of the infantry, were unable to reply, or render the necessary support to the attacking party. Owing to this fact, which was unknown to me when the assault took place, the enemy was enabled to throw a strong force of infantry against our left, already wavering under a concentrated fire of artillery from the ridge in front, and from Cemetery Hill, on the left. It finally gave way, and the right, after penetrating the enemy's lines, entering his advanced works, and capturing some of his artillery was attacked simultaneously in front and on both flanks, and driven back with heavy loss.

The troops were rallied and reformed, but the enemy did not pursue.

A large number of brave officers and men fell or were captured on this occasion. Of Pickett's three brigade commanders, Generals Armistead and [R.B.] Garnett were killed, and General Kemper dangerously wounded.

Major-General Trimble and Brigadier-General Pettigrew were also wounded, the former severely.

The movements of the army preceding the battle of Gettysburg had been much embarrassed by the absence of the cavalry. As soon as it was known that the enemy had crossed into Maryland, orders were sent to the brigades of [B.H.] Robertson and [William E.] Jones, which had been left to guard the passes of the Blue Ridge, to rejoin the army without delay, and it was expected that General Stuart, with the remainder of his command, would soon arrive. In the exercise of the discretion given him when Longstreet and Hill marched into Maryland. General Stuart determined to pass around the rear of the Federal Army with three brigades and cross the Potomac between it and Washington, believing that he would be able, by that route to place himself on our right flank in time to keep us property advised of the enemy's movements. He marched from Salem on the night of June 24, intending to pass west of Centreville, but found the enemy's forces so distributed as to render that route impracticable. Adhering to his original plan, he was forced to make a wide detour through Buckland and Brentsville, and crossed the Occoquan at Wolf Run Shoals on the morning of the 27th. Continuing his march through Fairfax Court-House and Dranesville, he arrived at the Potomac, below the mouth of Seneca Creek, in the evening.

He found the river much swollen by the recent rains, but after great exertion, gained the Maryland shore before midnight with his whole command.

He now ascertained that the Federal Army, which he had discovered to be drawing/toward the Potomac, had crossed the day before, and was moving toward Frederick, thus interposing itself between him and our forces.

He accordingly marched northward, through Rockville and Westminster, to Hanover, Pa., where he arrived on the 30th; but the enemy advanced with equal rapidity on his left, and continued to obstruct communication with our main body.

Supposing, from such information as he could obtain, that part of the army was at Carlisle, he left Hanover that night, and proceeded thither by way of Dover.

He reached Carlisle on July 1, where he received orders to proceed to Gettysburg.

He arrived in the afternoon of the following day, and took position on General Ewell's left. His leading brigade, under General Hampton, encountered and repulsed a body of the enemy's cavalry at Hunterstown, endeavoring to reach our rear.

General Stuart had several skirmishes during his march, and at Hanover quite a severe engagement took place with a strong force of cavalry, which was finally compelled to withdraw from the town.

The prisoners taken by the cavalry and paroled at various places amounted to about 800, and at Rockville a large train of wagons coming from Washington was intercepted and captured. Many of them were destroyed, but 125, with all the animals of the train, were secured.

The ranks of the cavalry were much reduced by its long and arduous march, repeated conflicts, and insufficient supplies of food and forage, but the day after its arrival at Gettysburg it engaged the enemy's cavalry with unabated spirit, and effectually protected our left.

In this action, Brigadier-General Hampton was seriously wounded, while acting with his accustomed gallantry.

Robertson's and Jones' brigades arrived on July 3, and were stationed upon our right flank. The severe loss sustained by the army and the reduction of its ammunition, rendered another attempt to dislodge the enemy inadvisable, and it was, therefore, determined to withdraw.

The trains, with such of the wounded as could bear removal, were ordered to Williamsport on July 4, part moving through Cashtown and Greencastle, escorted by General Imboden, and the remainder by the Fairfield road.

The army retained its position until dark, when it was put in motion for the Potomac by the last-named route.

A heavy rain continued throughout the night, and so much impeded its progress that Ewell's corps, which brought up the rear, did not leave Gettysburg until late in the forenoon of the following day. The enemy offered no serious interruption, and after an arduous march, we arrived at Hagerstown in the afternoon of the 6th and morning of July 7.

The great length of our trains made it difficult to guard them effectually in passing through the mountains, and a number of wagons and ambulances were captured. They succeeded in reaching Williamsport on the 6th, but were unable to cross the Potomac on account of the high stage of water. Here they were attacked by a strong force of cavalry and artillery, which was gallantly repulsed by General Imboden, whose command had been strengthened by several batteries and by two regiments of infantry, which had been detached at Winchester to guard prisoners, and were returning to the army.

While the enemy was being held in check, General Stuart arrived with the cavalry, which had performed valuable service in guarding the flanks of the army during the retrograde movement, and, after a short engagement, drove him from the field. The rains that had prevailed almost without intermission since our entrance into Maryland, and greatly interfered with our movements, had made the Potomac unaffordable, and the pontoon bridge left at Falling Waters had been partially destroyed by the enemy. The wounded and prisoners were sent over the river as rapidly as possible in a few ferry-boats, while the trains awaited the subsiding of the waters and the construction of a new pontoon bridge.

On July 8, the enemy's cavalry advanced toward Hagerstown, but was repulsed by General Stuart, and pursued as far as Boonsborough.

With this exception, nothing but occasional skirmishing occurred until the 12th, when the main body of the enemy arrived. The army then took a position previously selected, covering the Potomac from Williamsport to Falling Waters, where it remained for two days, with the enemy immediately in front, manifesting no disposition to attack, but throwing up entrenchment's along his whole line.
