With the exception of George Washington, perhaps the most famous general in American history is Robert E. Lee, despite the fact he led the Confederate Army of Northern Virginia against the Union in the Civil War. As the son of U.S. Revolutionary War hero Henry "Light Horse Harry" Lee III, and a relative of Martha Custis Washington, Lee was imbued with a strong sense of honor and duty from the beginning. And as a top graduate of West Point, Lee had distinguished himself so well before the Civil War that President Lincoln asked him to command the entire Union Army. Lee famously declined, serving his home state of Virginia instead after it seceded.
Lee is remembered today for constantly defeating the Union's Army of the Potomac in the Eastern theater from 1862-1865, considerably frustrating Lincoln and his generals. His leadership of his army led to him being deified after the war by some of his former subordinates, especially Virginians, and he came to personify the Lost Cause's ideal Southern soldier. His reputation was secured in the decades after the war as a general who brilliantly led his men to amazing victories against all odds.
Despite his successes and his legacy, Lee wasn't perfect. And of all the battles Lee fought in, he was most criticized for Gettysburg, particularly his order of Pickett's Charge on the third and final day of the war. Despite the fact his principle subordinate and corps leader, General James Longstreet, advised against the charge, Lee went ahead with it, ending the army's defeat at Gettysburg with a violent climax that left half of the men who charged killed or wounded.
Meade exemplified modesty and competence, serving as a career United States Army officer and civil engineer who fought with distinction in the eastern theater of the Civil War. During the first half of the war, Meade rose from command of a brigade to command of a division and finally command of the entire Army of the Potomac just days before the Battle of Gettysburg. Naturally, he is best known for defeating Robert E. Lee's Army of Northern Virginia at Gettysburg in July 1863, although he's not nearly as well remembered as his Confederate counterpart, and he has even been eclipsed in popularity by some of the men he commanded at Gettysburg, like Joshua Chamberlain. Meade continued to lead the Army of the Potomac, but when Grant attached himself to the army in 1864, it was Grant who essentially commanded the army, creating an awkward situation that Meade persevered through until the end of the war, to his credit.
If Meade distinguished himself at places like Antietam and Gettyburg, why is he frequently left out of the historical narrative of the war? Meade had a notoriously short temper that hurt his popularity with the press, his men and contemporaries during the war, despite how well he commanded. Perhaps more importantly, Meade's relatively early death in the decade after the war prevented him from defending his record and his decisions during and after Gettysburg. Lincoln mistakenly thought Meade blundered by not being more aggressive in pursuit of Lee after Gettysburg, when in fact Lee's men constructed strong defenses and invited attack on a number of occasions during their retreat. Just as significantly, Meade came under attack by generals like Daniel Sickles, who sought to shield themselves from scrutiny by blaming Meade for poor decisions.
