When Longstreet's men arrived around midday on August 29, Lee planned a flanking attack on the Union Army, which was concentrating its attention on Jackson.

On the next day, Longstreet's preparations paid dividends, as his artillery was a major factor in helping Jackson resist the V Corps attack, and he capitalized on Federal confusion by launching an attack of his own, anticipating an order from Lee that had not yet arrived.

Despite the smashing victory that followed, Longstreet's performance at the battle was criticized by postbellum advocates of the Lost Cause, claiming that his slowness, reluctance to attack, and disobedience to Gen. Lee were a harbinger of his controversial performance to come on July 2, 1863, at the Battle of Gettysburg.

Three of Longstreet's brigades were still in march column, and some distance from the attack positions they would need to reach.

Although Longstreet's motivations have long been clouded by the vitriol of the Lost Cause partisans ( see Legacy ), many historians agree that Longstreet did not aggressively pursue Lee's orders to launch an attack as early as possible.

The momentum of the attack subsided without Longstreet's active leadership and Gen. Lee delayed further movement until units could be realigned.

At the Second Battle of Bull Run, the 5th New York, along with another Zouave regiment, the 10th New York " National Zouaves ", held off the flanking attack of James Longstreet's Corps for ten crucial minutes before it was overrun.

Longstreet's attack drove one-third of the Union army, including Rosecrans himself, from the field.

During the en echelon attack that started with James Longstreet's assault on the right, from the Round Tops through the Peach Orchard, Pender's division was to continue in the attack sequence near Cemetery Hill, to the left of Maj. Gen. Richard H. Anderson's attack on Cemetery Ridge.

Hill and Longstreet, under Longstreet's overall command, turned out to be the only ones to follow Lee's order to attack the main Union concentration.

Early's writings place the Confederate defeat at Gettysburg squarely on Longstreet's shoulders, accusing him of failing to attack early in the morning of July 2, 1863, as instructed by Lee.

This delay and Longstreet's instructions to stand by and wait for orders prevented Huger's division from supporting the advance on time and hampered the overall Confederate attack.

At the Second Battle of Bull Run, Kemper's division took part in Longstreet's surprise attack against the Union left flank, almost destroying Maj. Gen. John Pope's Army of Virginia.

The plan from General Robert E. Lee was for Longstreet's Corps to maneuver into position and attack northeast, up the Emmitsburg Road, to roll up the Union left flank.

Although McClellan arrived in the area on September 16, his trademark caution delayed his attack on Lee, which gave the Confederates more time to prepare defensive positions and allowed Longstreet's corps to arrive from Hagerstown and Jackson's corps, minus A. P. Hill's division, to arrive from Harpers Ferry.

At the Second Battle of Bull Run ( Second Manassas ), Stuart's cavalry followed the massive assault by Longstreet's infantry against Pope's army, protecting its flank with artillery batteries.

In December, Longstreet's First Corps played the decisive role in the Battle of Fredericksburg.

Longstreet's actions at the Battle of Gettysburg would be the centerpiece of the controversy that surrounded him for over a century.

Longstreet's entire corps was absent from the Battle of Chancellorsville in May 1863, as it was detached on the Suffolk Campaign.

While the rest of Longstreet's corps was located around Suffolk, Virginia, Alexander accompanied Stonewall Jackson on his flanking march at the Battle of Chancellorsville in May 1863, and his artillery placements in Hazel Grove at Chancellorsville proved decisive.

Alexander's most famous engagement was on July 3, 1863, at the Battle of Gettysburg, during which he was in command of the artillery for Longstreet's corps.

Transferred with many of Longstreet's troops to the Western Theater, Hood led a massive assault into a gap in the Union line at the Battle of Chickamauga, but was wounded again, requiring the amputation of his right leg.

He led the division in the Northern Virginia Campaign and added to his reputation as the premier leader of shock troops during Longstreet's massive assault on John Pope's left flank at the Second Battle of Bull Run, which nearly destroyed the Union army.

In the Battle of Fredericksburg in December, Hood's division saw little action, placed in the center, between Longstreet's lines on Marye's Heights, and Jackson's lines.

And in the spring of 1863, he missed the great victory of the Battle of Chancellorsville because most of Longstreet's First Corps was on detached duty in Suffolk, Virginia, involving Longstreet himself and Hood's and George Pickett's divisions.

At the Battle of Gettysburg, Longstreet's Corps arrived late on the first day, July 1, 1863.

Because he was with Lt. Gen. James Longstreet's First Corps near Norfolk, Virginia, in the spring of 1863, he missed the Battle of Chancellorsville.

Early in September, Lee dispatched two divisions of Lt. Gen. James Longstreet's Corps to reinforce the Confederate Army of Tennessee for the Battle of Chickamauga.

He did not participate in the Battle of Chancellorsville in May 1863 because Longstreet's Corps was assigned duties in Suffolk, Virginia.

By May 4, the last of Longstreet's command had crossed the Blackwater River en route to Richmond.

At the Battle of Chancellorsville in May 1863, Barksdale's Brigade was one of the few units in James Longstreet's Corps that was present at the battle ; most of the corps was detached for duty in Suffolk, Virginia.

He personally arrived too late to participate in the battle, but served as Longstreet's chief of artillery in the subsequent Knoxville Campaign and in the Department of East Tennessee in early 1864.

Bragg had already begun an unsuccessful attempt to interpose his army between Rosecrans and Chattanooga before the arrival of Longstreet's corps.

Just before his death, however, his opinion changed about the lost cause movement, and he began speaking out about Longstreet's failures at Gettysburg.

As the Union cavalry neared the crossroads, they discovered and engaged one of Longstreet's infantry brigades with artillery that had arrived the day before.
