captured Maryland Heights at Harpers Ferry. He marched his division to Sharpsburg, Maryland, and defended the West Woods in the Battle of Antietam. Lee was disappointed in McLaws's slow arrival on the battlefield. At the Battle of Fredericksburg, McLaws's Division was one of the defenders of Marye's Heights, and he satisfied Lee with his ferocious defensive performance. 1863–65 At Chancellorsville, while the rest of Longstreet's corps was detached for duty near Suffolk, Virginia, McLaws fought directly under Lee's command. On May 3, 1863, Lee sent McLaws's Division to stop the Union VI Corps under Maj. Gen. John Sedgwick marching toward Lee's rear. He did accomplish this, but Lee was disappointed that McLaws had not attacked more aggressively and caused more harm to Sedgwick's corps, instead of letting him escape across the Rappahannock River. When Lee reorganized his army to compensate for Jackson's mortal wounding at Chancellorsville, Longstreet recommended his subordinate for one of the two new corps commands, but both men were disappointed when Lee chose Richard S. Ewell and A. P. Hill instead. McLaws requested a transfer, but it was denied. On the second day of the Battle of Gettysburg, July 2, 1863, McLaws commanded the second division to step off in Longstreet's massive assault on the Union left flank. He achieved great success (at a high cost in lives) in the areas known as the Wheatfield and the Peach Orchard, but the army as a whole was unable to dislodge the Union forces from their positions on Cemetery Ridge. His division did not participate in Pickett's Charge the next day, despite Longstreet's command of that assault. McLaws accompanied Longstreet's corps to Tennessee to come to the aid of General Braxton Bragg's Army of Tennessee. He arrived too late to lead his division at Chickamauga, where it was led by Brig. Gen. Joseph B. Kershaw, but he did participate in the Chattanooga Campaign. In the Knoxville Campaign later in 1863, Longstreet relieved McLaws due to the failure of the attack on Fort Sanders, citing "a want of confidence in the efforts and plans which the Cmdg Genl has thought proper to adopt." In a letter addressed to Confederate Adjutant and Inspector General Samuel Cooper on December 30, Longstreet submitted three charges of "neglect of duty"; however, he did not request a court-martial because McLaws's "services might be important to the Government in some other position." (In that same letter,
