Here Jeb Smith argues that General George B. McClellan was the most underrated army commander of the Civil War. While he does not consider him to be a great general or military genius, he thinks the common portrayal of him as a terrible commander is unjust. No other Northern general, people say, exemplifies the stereotype of an incompetent and timid leader as McClellan does. The author argues that this is an unwarranted perception.

“No other general in the war commanded more respect and admiration from his men than George McClellan.”
-John Cannan The Antietam Campaign
“Remember that your only foes are the armed traitors,–and show mercy even to them when they are in your power, for many of them are misguided” and later “Bear in mind that you are in the country of friends, not of enemies,–that you are here to protect, not to destroy.”
-George B McClellan May 26 1861 and June 25 1861
Northern Democrats did not see the South as the spawn of Satan but rather as fellow Americans who, in fact, had produced most of the Union leaders up to that point. General McClellan, a Democrat, held tolerant views of the South and sought to avoid needless bloodshed. These perspectives stand in contrast to those of many modern historians and the Republicans of the time, who shaped the narrative to justify the massacres that would follow, as well as the total warfare of 1864 and 1865.
West Virginia and Promotion
“Harley six weeks had elapsed... and in that time he had actually created an army and began the first campaign.”
-George b McClellan Commanding General U.S army May 26 1861
George B. McClellan, nicknamed “Young Napoleon” or “Little Mac,” graduated second in his class of 59 at the U.S. Military Academy in 1846. His class included 20 future full-rank generals, and he later returned to West Point as an instructor.
After the war began, he excelled at organizing militia from three states into a cohesive fighting force and saw his first action as a commander of Union forces in what is now West Virginia. This was a departure from his later reputation as a slow-moving, timid general. During a successful campaign in the mountainous region he launched aggressive attacks, dislodged Confederate forces, and captured key positions. He forced the retreat of Confederate troops fortified in the mountain terrain, all while taking minimal losses and securing large supply bases and many prisoners. This success helped preserve the future West Virginia for the Union and prevented the destruction of the Baltimore and Ohio Railroad. President Lincoln was very impressed, which led to McClellan’s appointment to replace McDowell after the latter’s defeat in the Battle of First Manassas[1], and later as the commander of all Union forces.
Organization of the Army of the Potomac
“In a very real sense, McClellan rescued the Union in these early days from dependency and fear. Someone had to rebuild the army and show the country that there was great hope for the future.”
-S.C. Gwynne Rebel Yell: The Violence, Passion and Redemption of Stonewall Jackson Simon and Schuster 2014
The nonmilitary press and President Abraham Lincoln, who was pressured for political reasons, wanted quick action and a fast end to the war. Part of what fueled this was the North's inability (even after First Manassas) to see how determined the South was. They thought this would be a quick, easy conflict. They underestimated the South's resolve to fight and ability to wage war. So, while the press and Lincoln called on Mac for fast action, as a military man Mac understood that the demoralized citizen army needed discipline, training, and organization. He provided these, got rid of poorly-performing generals and instilled spirit and pride in the soldiers while increasing their morale. He came to be loved and revered by his men.
One thing even those who are critical of him admit is that he was a first-rate organizer of the army. Mac took a defeated militia force and turned it into a professional army.
“McClellan had started with…a collection of undisciplined, ill-officered, and un-instructed men, who were, as a rule, much demoralized by defeat and ready to run at the first shot. He ended with the finest army ever seen on the North American continent.”
-James V. Murfin Battlefields of the Civil War
Had the North attacked before they were ready, as Lincoln and the press called for, the result would likely have been further defeats and a shattering blow to national morale. As General Sherman stated, Napoléon took three years to build an army, yet “here it's expected in ninety days, and Bull Run is the consequence.”
Mac's offensive plan, as called for by many in the North, was to mass a large army, some said up to 200,000, to march on Richmond and end the war. The Northern people wanted no mistakes after First Manassas. This was Mac's general plan; one that would take time and preparation. Mac also constructed large fortifications around D.C., which had been left almost entirely unguarded by McDowell, including 48 forts and 480 guns. Given that Mac had to train, organize, recruit, and supply a massive citizen army and transform it into a world-class professional army, the time he took to do so was entirely reasonable.
“When I was placed in command of the armies of the United States, I turned my attention to the whole field of operations, regarding the army of the Potomac as only one, while the most important, of the masses under my command.”
-George B. McClellan 1861
Further, Mac was commander of all armies and planned for a simultaneous synchronized attack across the Confederacy, which would take further time to plan and put in motion. On August 4th, 1861, in a letter to Lincoln, he laid out his plan that included the main attack to be against Richmond but also simultaneously pushing into Missouri and down the Mississippi, and after Kentucky joined the Union to push into Tennessee, seizing Nashville, and also begin capturing coastal cities such as New Orleans, Savannah and Mobile, then move on to Montgomery and Pensacola. Mac wanted one massive assault to wipe out the South and not a prolonged war; this would take time to prepare. In February 1862 he wrote to Secretary of War Stanton, saying “I have ever regarded our true policy as being that of fully preparing ourselves and then seeking for the most decisive results; – I do not wish to waste life in useless battles, but prefer to strike at the heart.” He did not want years of bloodshed to wear down the South, but brief, decisive action to end the war quickly.
Demotion by Lincoln
Just when Mac felt his army was ready, winter had started in, and Mac was bedridden for three weeks around Christmas. Lincoln wanted action now despite the impassable roads (he would not demand Grant move this early in ‘64) and Mac was accused of being timid. This offensive action was attempted in the winter of ‘62 by Burnside, and the results were Fredericksburg and the “mud march,” which ended in Burnside's removal. Grant, in ‘64, would start his spring offensive in April, later than Mac would his Peninsula campaign. As Grant said, the roads in Virginia would not allow large movements of troops before then, leading William Swinton in Campaigns of the Army of the Potomacto write, “It was inevitable that the first leaders should be sacrificed to the nation’s ignorance of war.”
So Mac started at the average time for spring offensives. No other Union army was campaigning during this winter. Yet, because of Lincoln's urgency and what he saw as a too-cautious McClellan, he demoted Mac to simply commander of the Army of the Potomac. Lincoln also forced corps commanders he had chosen on the Army of the Potomac. Mac wanted to wait to promote generals until he had seen them in battle. This was not the last time a politician interfered with Mac's plans.
Peninsula Campaign Begins
“Reduced my force by 1/3, after (bless and do not curse) task had been assigned, its operations planned... it frustrated all my plans... it left me incapable of continuing operations which had been begun. It made rapid and brilliant operations impossible.”
-George B McClellan
“Let me tell you that if your government had supported General McClellan in the field as it should have done, your war would have been ended two years sooner than it was.”
-- General Helmuth von Moltke, Chief of Staff of the Prussian Army and one of the leading military experts of the 19th Century
The Peninsula Campaign began with McClellan's strategic plan for an amphibious operation. Leveraging the North's naval superiority to transport and supply his army, he ultimately aimed for Richmond. Mac anticipated having over 150,000 men for the campaign as he set out for the peninsula. However, once he landed, Lincoln would significantly reduce his army with the other troops spread around the valley, D.C., and the Manassas region.
Mac had wanted more men for the offensive, but Lincoln wanted him to hold men back to guard D.C. Lincoln forced Mac to leave McDowell’s I Corps in D.C. along with the garrison already available. Lincoln now had a garrison of around 20,000 in D.C. and up to 74,000 as far as N.Y. that could be shipped/railed/marched to D.C. if it were attacked. Plus, McClellan had set up world-class fortifications. McClellan, McDowell, Winfield Scott, and every corps commander believed this was more than enough men to guard D.C. and supported McClellan's plan to bring more men, but Lincoln would not allow it for fear of D.C. being attacked. Perhaps out of fear of Stonewall Jackson, it was Lincoln, not the general, who, in this instance, was being overly cautious. In Life and Campaigns of George B. McClellan (1864), author George Stillman Hillard wrote, “From the moment the Army of the Potomac landed upon the Peninsula an uneasy sense of insecurity took possession of the minds of the President, the Cabinet, and the members of Congress.”
So Mac landed the army, which was slow-moving because it was massive and carried heavy siege equipment. He faced the largest army the South would field during the war, 88,000 (Grant faced 65,000 in ’64, with a more significant force under him than Mac enjoyed). Once his army landed, he was notified that Stanton had closed all the recruiting depots in the Union. His army would now have to do without either replacements or reinforcements during a major campaign.
This was a massive shock to Mac and the generals in the army. He then was told that McDowell's 40,000 men near Manassas could not be used but must help defend against any possible action towards D.C., despite the fact that Confederates showed no signs of attacking and even burned the bridges south of Manassas as they retreated to defend Richmond. McDowell told McClellan this decision (McDowell protested it) was “Intended [as] a blow to you.” Then McClellan was told the garrison of 10,000 men at Fort Monroe would also be withheld. Even critics of McClellan, like General Heintzelman, said it was a “great outrage” to withhold his army from his command. General Wells said it was the Radical Republicans trying to get Mac to resign. Harper’s Weekly stated, “It is impossible to exaggerate the mischief which has been done by division of counsels and civilian interference with military movements.” Once more, Mac was aggressive, Lincoln and the politicians conservative.
“In General McClellan’s opinion, the way to defend Washington was to attack Richmond; and the greater the force thrown against the rebel capital, the greater the security of our own.”
-George Stillman Hillard Life and Campaigns of George B McClellan 1864
Mac was now forced to revise his plans because of Lincoln's caution. In the revised plan, McDowell would advance on Richmond from the north with his 40,000 men and better protect against an attack by Confederate General Joe Johnston if he went north to Washington. However, as Mac argued, the attack on Richmond would force the Confederate army to defend their capital rather than launch a desperate attack on D.C. This disagreement delayed the start of the campaign, with Lincoln getting his way.
“Notwithstanding all that has been said and written upon this subject, I have no hesitation in expressing the opinion, that had not the President and his advisors stood in such ungrounded fear for the safety of Washington, and had not withheld McDowell's forces at a time when their absence was a most serious blow to the plans of General McClellan, the close of the year would have seen the Rebellion crushed, and the war ended.”
-- Allan Pinkerton, chief of the Union Intelligence Service, 1861-1862
Yorktown
Mac moved up the peninsula towards Richmond and was promised McDowell’s men if D.C was free of threat. His army's first encounter was with Confederate General John Magruder and a small Confederate force at Yorktown. Magruder skillfully deceived Mac into believing his force was larger than it actually was. He accomplished this by repositioning the same troops in various locations, acting aggressively, continuously moving small units, using ammunition freely, and setting up dummy defensive positions. This convinced Mac that the Confederate force was more significant than it truly was, prompting him to settle in for a siege while he awaited the arrival of his heavy artillery. Mac was concerned that his inexperienced troops might fail in an assault during the first battle of the campaign, which could damage their morale. Mac eventually captured Yorktown and 80 heavy guns without losses, but the delay gave the Confederates time to organize troops to defend Richmond.
Advance on Richmond
Mac then started to push toward Richmond, and the Confederates gave way. The Union army captured both supply and ordnance during this advance. Mac is criticized for slow movement with a smaller Confederate force in front of him, yet he relied upon his friend and “expert” spy Alan Pinkerton, founder of the Pinkerton Detective Agency. Whatever the value of Pinkerton’s other information, one area in which he failed was in accurately assessing enemy troop numbers. He gave Confederate force numbers from various agents as 160,000, 123,000, 180,000, and even 200,000 in Richmond. And on August 6, Federal General Halleck gave estimates of 200,000 around Richmond. Some northern newspapers working independently gave even higher estimates than Mac did. Because of this, Mac actually believed he was outnumbered.
This was common during the war, with generals thinking the force opposing them was more extensive than it really was. Since this was his information, he believed he was not being cautious but aggressive and daring to continue the campaign, even if at a slow/careful pace. At the time, the enemy numbers were not certain. Mac also waited for his heavy siege artillery to come up from the back, as it was needed to attack Richmond's prominent forts at the Confederate capital.
But without a doubt, the advance was working. Richmond was preparing to evacuate. It forced the Confederates to scuttle the ironclad Virginia, which caused a loss of morale throughout the Confederacy. Confederate General Joe Johnston called General Ewell from Jackson to help in Richmond. McDowell was advancing unopposed north of Richmond. Mac had achieved better success than McDowell, Burnside, Hooker, or Meade advancing on Richmond.
“It was not until 1864 that another Union army, led by Grant, would get as close to Richmond as McClellan did in the spring of 1862.”
--Great Campaigns: The Peninsula Campaign David G. Martin Combined Books PA 1992
The next time the Federals would get this close was under their top general, U.S. Grant. They also fought against a weakened Southern army in ‘64 with a much larger Federal army.
But this time, three things saved Richmond and stopped Mac from capturing the Confederate capital and being hailed as a hero. All three had to happen to stop Mac; two of them were very unlikely and could not have been foreseen.
1] Jackson in the Valley
“The most significant contrast between the Virginia campaigns of Grant and McClellan is that Early's offensive did not accomplish its ultimate objective–to relieve the pressure on Lee's army at Petersburg, Jackson's campaign in the Shenandoah valley did. Unlike McClellan before him, Grant would not be forced to alter his designs on the James River one iota.
-Thomas Rowland George B. McClellan and Civil War History
Unlike Lincoln, Mac saw Jackson's valley campaign as a diversion by Lee (now in command of the Southern Army) to pull federals away to help protect Richmond. Richmond was saved because of Jackson's brilliance in the valley. He outmaneuvered and outfought a force over three times the size of his own (17,000- 60,000), defeating them in multiple battles while also threatening D.C.
Jackson knew Lincoln was concerned with protecting D.C. Hence, he knew that aggressive maneuvers would pull men from the peninsula and help save Richmond. Jackson kept 71,000 additional men away from the Richmond attack with his victories and aggressive maneuvering. Lincoln was constantly scared by what Jackson might do, and this prevented McDowell and other troops from helping Mac; the withholding of McDowell would prove decisive.
2] Lincoln Recalling Troops to the Valley
“[It was] Jackson's campaign, and the insane terror it inspired in Washington, which was the true cause of the failure on the peninsula.”
-Colonel Ferdinand Lecomte, quoted in George Stillman Hillard Life and Campaigns of George B. McClellan 1864
Because of Jackson, Lincoln recalled troops to defend Washington and the valley. He also held back McDowell's 40,000 from the attack on Richmond. This “Changed the whole nature of the confrontation near Richmond,” and “The Confederacy was truly handed an amazing gift.” Mac would have rather left Jackson to clear out the valley and even attack D.C. if he wished. Mac had built massive forts with a large garrison to protect the capital.
“Here is the true defense of Washington, it is here on the banks of the James.”
-McClellan to Halleck August 4th, quoted in George Stillman Hillard Life and Campaigns of George B. McClellan 1864
After Pinkerton reported a large number of enemy forces to McClellan, he paused his attack due to McDowell's absence. McDowell was supposed to launch an assault on Richmond from the north to prevent the Confederates from mounting counterattacks. McDowell described his recall to the valley as “a crushing blow to us.” Even Lincoln told McClellan, “If you believe you are not strong enough to take Richmond, just know that I do not ask you to try. Just know.”
3] Lee Replaces Joe Johnston
General Joe Johnston, the commanding Confederate general, was injured and replaced by Robert E. Lee. This would change the entire campaign. Mac had been slowly pushing Johnston back towards Richmond, but Lee would take the initiative and attack Mac.
Lee vs Mac
Lincoln’s maneuvers significantly reduced the Mac forces near Richmond attempting to trap Jackson in the valley. Heavy rains swelled the Chickahominy River and created a split the Potomac army, and Lee saw his opportunity.
Lee, whom many consider not only the premier general of the South but of the war, recalled Jackson from the valley to help in the offensive vs. Mac, now with a force nearly equal to his.
Lee would strike the smaller portion of Mac's army and threaten its supply line under General Porter. Porter was supposed to be supported by McDowell from the north to meet up with his flank coming south from Manassas. Had Mac's plan been allowed, the attack would not have been possible. However, when Lincoln sent McDowell to the valley to trap Jackson, Porter was vulnerable, and Lee pounced, enabling its strategic success.
“General McClellan wished and had advised that reinforcements should be sent him by water, as their arrival would be more certain. Now that the James River was open, they might have been sent by that route... Richmond could have been approached by the James, and we should have escaped the delays and losses incurred by the bridging of the Chickahominy, and should have had the army massed in one body instead of necessarily being divided by that stream... the capture of Richmond could not be carried out because to the president’s distempered fancy Washington was not safe... McClellan was commanded to extend his right wing to the north of Richmond, in order to establish the communication between himself and General McDowell. This was running a great risk in case General McDowell should not come, because it exposed our right in a way no prudent officer would have done; and, as General McDowell did not come, the enemy did not fail to take advantage.”
-George Stillman Hillard Life and Campaigns of George B. McClellan 1864
Lee attacked in multiple bloody battles, resulting in high losses on both sides. Mac would cause high casualties to Lee during the campaign, inflicting more losses than he received. However, Mac, going from “expert” information, believed he was outnumbered and was in danger of being cut off without help from the north. With Lincoln recalling so many of his troops, he ordered a retreat off the peninsula. Mac telegraphed D.C., stating, “If I save this army now, I tell you plainly I owe no thanks to you or to any other persons in Washington...you have done your best to sacrifice this army.”
The retreat on the peninsula was dangerous, yet McClellan and Porter skillfully conducted it to save their forces from disaster. Mac would withdraw by night and defend a favorable position by day. It was a major strategic victory for the South yet a tactical victory for the Union. Lincoln called it a “half defeat.” Given the force size and causalities suffered, Mac performed better than the future Union commanders of the Army of the Potomac.

Antietam/Mac Takes Command
“I must have McClellan to reorganize this army and bring it out of chaos...there is no man in this army who can man these fortifications and lick these troops into shape half as well as he can.”
-Abraham Lincoln
“General McClellan has again assumed the supreme command of the army... His reception by the officers and soldiers was marked by the most unbounded enthusiasm. In every camp his arrival was greeted by hearty and prolonged cheering... Already his... visit to our camps has wrought a remarkable change in the soldiers. His presence seemed to act magically upon them; despondency is replaced by confidence, and all are glad that McClellan will, hereafter direct them.”
-Ellis’s Leaves from the Diary of an Army Surgeon, p. 214, quoted in George Stillman Hillard Life and Campaigns of George B. McClellan 1864
Lincoln's selection of the aggressive Republican general John Pope to lead the army led to the embarrassment at Second Manassas. Pope was then exiled to Minnesota to fight Indians, and Lee turned his attention to an invasion of the North. Meanwhile, Mac had to reorganize Pope’s defeated, demoralized army that was integrated into his command and try to restore morale. Mac was reinstated in command of Pope's army and the Army of the Potomac on September 2nd. The effect was immediate:
“The effect of the news was instantaneous. All of a sudden the federals forgot their defeat, weariness, and hunger and exploded into triumphant hurrahs, multitudes of caps were thrown in the air.”
-John Cannan The Antietam Campaign
Slow to Meet Lee?
A common criticism of McClellan during the Antietam campaign is that he was slow to move the army out to confront Lee's invasion, which allowed Lee to enter Maryland. Lee entered Maryland around September 4-7. Mac had just taken control of a disorganized, defeated army on the 2nd, and “worked a minor miracle in the next few days as he restored the army's morale and organization, and equally significant, its pride and sense of purpose.” No other man in the army could have restored morale and cohesion as quickly as Mac did before the Battle of Antietam. He had reorganized his army and marched to meet Lee by September 9th. Lee had expected a longer time for Mac to prepare, and his fast reaction spoiled Lee's plan to capture Harrisburg, Pennsylvania. In his article Showdown on South Mountain historian Dennis Frye wrote, “Pennsylvania was Robert E Lee's target in September 1862. But Maryland and George McClellan got in the way.”
Mac had other reasons to be cautious. General Halleck advised General McClellan to be watchful regarding Washington, D.C., and to wait until General Lee's intentions were fully understood. Halleck believed that Lee was attempting to draw McClellan out, rather than planning a direct attack on D.C. Additionally, McClellan received continual reports from his cavalry regarding enemy troop strength, estimating between 60,000 and 120,000 soldiers. General Porter estimated Lee's army to be 100,000, while General Sumner's assessment was 130,000. This information was accepted by the Union high command, who believed that Lee must have been reinforced in preparation for an invasion.
Mac moved west, forcing Lee to fall back to link with Jackson from Harpers Ferry. Mac helped lead the attack at the Crampton’s Gap, Turner’s Gap and Fox's Gap battles—all victories. At Turner's Gap, CSA losses were 2,300 and USA losses 1,800, even though the attack was up a mountain and through rough terrain. On Sep 16th, Mac trapped Lee by a flank maneuver on Lee's left and captured the road to Hagerstown, forcing Lee's northern invasion to end. Frye wrote, “Lee saw his invasion crumbling. The most important matter now was not Pennsylvania, but preservation of the army.” Mac even took the unpredictable and aggressive General Stonewall Jackson off-guard, causing him to say “I thought I knew McClellan, but this movement puzzles me.”
The Battle of Antietam
The two armies met near Sharpsburg, Maryland, on September 17th. The “cautious” Mac would assault the Confederate lines, leading to the bloodiest day of the war. Mac's plan was to attack both the Confederate left and right simultaneously, followed up with a massive reserve attack in the center.
While not a complete failure the attack failed to destroy Lee, partly due to Burnside's late arrival at the battle. Burnside delayed his assault on the Confederate right, “throwing off the whole plan,” and allowing Lee to shift reinforcements along his line to meet Union forces in the center and left. McClellan sent a half dozen couriers to Burnside to push him to strike more swiftly and threatened to relieve him of command. Yet, Lee's army was nearly breaking in all three sectors.
Mac did not show tactical genius and made some mistakes, but in the end, it was a strategic victory for the North and a tactical draw. He rested on the 18th to resupply (artillery near out of ammo) and gave orders to attack come daylight on the 19th, but the Confederates had left. The battle sent Lee's wounded army back to Virginia and, more importantly, ended any hopes the Confederacy had for European involvement in the war. Thus Frye wrote that “George McClellan saved the union.”
“A man who could take a demoralized army, as McClellan took the combined forces that had been defeated under Pope in front of Washington at the second Bull Run, restore its discipline by the magic of his name and his swift reconstruction of its shattered organizations, and then lead it to victory within fourteen days, after an almost unexampled celerity of movement against the enemy who had crushed it two weeks before--such a man is not to be spoken of or thought of as wanting in the force and vigor of a great general.”
-- George T. Curtis, U.S. Commissioner, historian

McClellan Allowed Lee to Escape?
Lincoln heavily criticized Mac for not destroying Lee's army and not following him back into Virginia. However, Mac had sent Porter to harass the enemy retreat, which had initial success, capturing 40 Confederate artillery pieces. However, A.P. Hill counter-attacked, pushing the Union men back across the Potomac. Hill said it was “The most terrible slaughter...a lesson to the enemy, and taught them to know it may sometimes be dangerous to press a retreating army.”
Often, retreating armies fought significant rearguard actions to prevent their own destruction. Civil War battles rarely ended with the destruction of one or other army, only in 1865 when the South was near defeat was an army nearly annihilated. The assumption it could happen in 1862 points more to the expectations of the early-war North than realistic military goals. When the army was criticized for not destroying Lee's forces, a soldier in the Army of the Potomac replied. “Think the rebel army can be bagged? Let them come and bag them. Easy to talk about.” Historian John Cannan said the counter attack showed the federals that the rebels “still had a formidable bite.” Dennis Frye, who studied the Antietam campaign for over 50 years, wrote that ideas that Lee could be easily destroyed were “Myths created by politicians” not accurate judgments based on historical truth.
Further, the Federals were low on supply and had just fought two large-scale engagements. Lee knew where Mac would be unable to supply his army and planned his withdrawal accordingly. Mac was also working off his cavalry’s and Pinkerton's estimates of the Confederate strength. Thinking the Confederates still had equal force, he chose not to push the attack or risk a loss on Maryland soil that would endanger D.C. and the outcome of the war.
Far from defeated, after Lee had fallen back to Virginia he planned to continue the attack again. He sent Stuart’s Cavalry to create a bridgehead at Williamsport, Maryland, to renew the invasion. However, Mac had anticipated this move and sent his own cavalry along with the 6th Corps to prevent such a move. As argued by Dennis Frye, Mac outthought Lee in Maryland.
Later in October, Mac's quick and aggressive move into the Warrenton, Virginia area surprised Lee, splitting Lee's army. Both Lee and Longstreet were concerned. However, Lincoln had given the order two days before, and Mac was removed from command.
Conclusion
“There are strong grounds for believing that he was the best commander the army of the Potomac ever had.”
-Francis Palfrey Antietam, Fredericksburg
While I would not go as far as the above quote does, I would say Mac was the most underrated general of the war. He does not get credit where he should and gets the blame where he should not. I do not see Mac as cautious to a fault as claimed. It was often Lincoln, Stanton, and Halleck being over-cautious about protecting D.C. that interfered with Mac's plans. And his military intel let him down, not his over-cautious nature.
“Look at his campaign in Western Virginia in 1861,–a part of his military career conveniently ignored by his enemies. Here he had a separate command, a defined field of action and was not hampered and trammeled by interference from Washington; and do we see any signs of indecision and want of promptness here? On the contrary, we observe the happiest combination of judgement in design and vigor in execution: one skilful and powerful blow was instantly followed by another, and the result was absolute and permanent military success.”
-George Stillman Hillard Life and Campaigns of George B. McClellan 1864
Lincoln and the press wanted aggression, and the results were First Manassas, Burnside at Fredericksburg, Pope at Second Manassas, and later Hooker at Chancellorsville. No general of the early war could handle the tandem of Jackson and Lee. Extreme events withheld Mac from the capture of Richmond in ‘62.
A fair critical comparison between Mac and Sherman/Grant is favorable to Mac. Later, when Grant/Sherman gained victories, it was more because of the Confederate armies' reduced capability to offer resistance than their ability to be outgeneral Mac.
I believe the real reason for Lincoln's disappointment with Mac was the North's high expectations. Underestimating the resolve of the South and their leadership, the North desired one battle and one victory in Virginia, which would win the war for them. But it took years for them to realize their error, though doubt began early as Lincoln wrote to his friend Carl Schurz in 1862, “I fear we shall at last find out that the difficulty is in our cause rather than in particular generals.”
“McClellan's relationship with Lincoln is central to any understanding of why historians judge him as a flawed personality...Lincoln has attained a stature that sets him apart from other mortals”
-Thomas J Rowland George B McClellan and Civil Har History: In the Shadow of Grant and Sherman Kent State University Press
Historians may have viewed McClellan negatively because he opposed and disagreed with Lincoln. He committed the “unpardonable sin” of running against Lincoln in the 1864 election on a peace platform aimed at ending the bloodshed. In 1864 George Stillman Hillard wrote, “The real reasons for which General McClellan was removed were political, and not military.” Historian Dennis Frye said “The Republicans could not allow McClellan to be a victor. They could not allow that to happen. They needed to do everything they could to smear McClellan.”
“However patriotic the abolitionist radicals in the north may have been, the very last thing they wanted was for Little Mac to win in the battle for Richmond....the abolitionists would lose their influence.”
-S.C. Gwynne Rebel Yell The Violence, Passion, and Redemption of Stonewall Jackson Simon and Schuster 2014
“There is a political element connected with this war which must not be overlooked.”
-Congressional Committee on the Conduct of the War Dec 26 1861 quoted in George Stillman Hillard Life and Campaigns of George B. McClellan 1864
Lincoln acknowledged that he made many errors that undermined McClellan's chances for success. After McClellan, Lincoln refrained from becoming directly involved with his generals. It appears that some historians have unfairly attributed Lincoln's military shortcomings to McClellan.
“At this moment a considerable portion of his countrymen have their minds barred against all arguments and considerations in defense of General McClellan, by political prejudice. To deny him all military capacity is part of the creed of a great political party. Most supporters of the present administration hold it to be a point of duty to disparage and decry him.”

McClellan was the only Union general to give more casualties than taken when faced with Lee. His average over two battles was only bested once by a Union commander, by Meade (who performed worse overall) at Gettysburg. Mac fought against Lee with, if anything, less of a manpower advantage than Grant would have later on. He also faced the Army of Northern Virginia while it had Jackson, was well supplied, and the South had high national morale, unlike what Grant faced.
How many other Union commanders can claim over two battles with Lee to have won a tactical victory on the first and a strategic victory and a tactical draw on the second while inflicting heavy losses? It is no wonder Lee said Mac was the best he faced. And famed Confederate John Mosby, the “gray ghost of the Confederacy,” said that McClellan was the best Union commander “by all odds.”
[1] The two battles at the same site were referred to as First and Second Manassas by the Confederacy, First and Second Bull Run by the Union. I will stick to Manassas throughout, except that where quotations from the Union side refer to Bull Run this will be left unchanged.
