As the day of battle at Antietam approached, Union General George B. McClellan miscalculated the number of troops that General Robert E. Lee had at his disposal on September 15, 1862. In fact Lee had less than half of the troops with which McClellan gave him credit for. There were logical reasons for this and they were not related to any of McClellan's previous problems when on a potential offensive as with the Peninsula campaign.McClellan and his commanders were misguided because:
1. A faulty intelligence gathering system;
2. The number of Confederate regimental flags that were visible on Lee's front lines;
3. The number of guns firing from Lee's lines at the Union position; and
4. Federal scouts had trouble determining whether fifty or five hundred rifles were being fired.
The situation was that although Lee's troops were depleted, the regiment flags were still posted indicating to McClellan that the regiments were in full force. They were not.
Confederate General Longstreet purposely had his artillery batteries firing at a super fast volume, deceiving the Federals.
Based on the above factors, McClellan decided to postpone any offensive decisions to the next day, the 16th which was also another missed opportunity.
Major George B. McClellan received poor advice from his cavalry and from local citizens regarding the number of troops he would have to battle against at Sharpsburg, known better as the Battle of Antietam. McClellan believed that Stonewall Jackson commanded between 40 to 50,000 troops and were close to joining General Lee at Sharpsburg, who commanded 30,000 soldiers.McClellan's estimates were vastly off target. When the Battle of Antietam finally began on September 17, 1862, Lee's total number of troops were barely 39,000.
The Battle of Antietam took place near the Antietam Creek, near Sharpsburg, Maryland in September of 1862. This was the first time Confederate General Lee took his forces into Union territory. Maryland was a slave state that remained in the Union. It was one of the bloodiest battles in American history. Union General Burnside, under the command of General George B. McClellan forced Lee back into Virginia as a result of the battle. Not long afterwards US President Lincoln visited General McClellan to see the battlefield itself.
General McClellan aimed to block General Lee at the crucial location of Antietam Creek during the Maryland Campaign. He recognized that the Confederate Army was divided, with part of Lee's forces stationed in Virginia and the other near Sharpsburg, Maryland. By engaging Lee at Antietam, McClellan sought to exploit this division and deliver a decisive blow to the Confederate forces. This strategic opportunity ultimately led to the bloodiest single-day battle in American history on September 17, 1862.
On September 16, 1862, one day before the historic Battle of Antietam, Major General George B. McClellan lost his best opportunity to defeat General Lee's army in detail in Maryland. McClellan was slow to assemble his forces in and around the town of Sharpsburg, Maryland. McClellan was unaware that he substantially outnumbers Lee's army and postpones an attack on the Confederates. Instead he waits another day until his reserve forces joins his main army. Theoretically, if McClellan conducted an assault on September 16, the Battle of Antietam would have been a smashing Union victory.
The Battle of Antietam, an important battle of the Civiil War, was fought by the Army of the Potomac, part of the Union Army, under the command of General George McClellan, and Confederate forces under the command of General Robert E. Lee on September 17, 1862.

General George B. McClellan was often deemed an ineffective leader due to his hesitance to engage decisively in battle, which led to missed opportunities during the Civil War. His overly cautious approach, particularly during key campaigns like the Peninsula Campaign, caused frustration among his troops and political leaders, including President Lincoln. Additionally, McClellan's failure to capitalize on advantages and his tendency to overestimate enemy strength contributed to perceptions of indecisiveness and lack of aggression. These factors ultimately resulted in his removal from command.
The Battle of Antietam took place on September 17, 1862. At the onset of the battle most of Lee's troops were in defensive positions to the west of the Antietam Creek. The town of Sharpsburg lay between to sections of Lee's army. Lee had made his headquarters on the southwest side of the town of Sharpsburg. Union General George B. McClellan was headquartered to the northeast of Lee. McClellan had made the east side of Antietam Creek. He was directly next to the Creek itself.
As the actual Battle of Antietam was soon to take place, General McClellan miscalculated the number of troops that Confederate General Robert E. Lee had on September 15, 1862, just two days from the Battle of Antietam.In actuality, Lee had only one half of the troops that General McClellan believed he had. If McClellan had attacked Lee's forces on the 15th of September, by all counts, the Army of Northern Virginia would have lost an overwhelming amount of its troops. As it happened, Lee had only 18,000 troops ready to fight versus McClellan's 40,000 troops. McClellan failed to attack.
General George B. McClellan was best known for his thorough planning and attention to the details of his army, but this quality also served as a double-edged sword in that he would often overestimate the strength of his enemy. This proved costly in battles such as Antietam, in which while technically winning due to Robert E. Lee's retreat, his hesitation in deploying his reserves to capitalize on the local successes throughout the battle would ultimately allow General Lee to escape with a large portion of his force intact. McClellan's giving in to caution and refusing to pursue Lee following the battle ultimately led to his removal by President Lincoln, and his replacement by General Ambrose Burnside.
General George B. McClellan often believed that the enemy was stronger and more formidable than they actually were. This tendency to overestimate Confederate forces led to his cautious approach to military engagements during the Civil War, resulting in missed opportunities for decisive action. His perceptions contributed to a reputation for being overly hesitant and cautious in his leadership.
After the US Civil War Battle of Antietam, Union General George B. McClellan remained in Sharpsburg, Maryland until the 26th of September. From his headquarters there he wired Henry Halleck that he would reoccupy Harper's Ferry in a day or two. This was possible as the Army of Northern Virginia was heading back to Virginia.

Lincoln's response to General McClellan's command was that Lincoln relieved McClellan of Command.
Captain George Custer was on a scouting mission for General George B. McClellan on September 15, 1862. He reported to the general that he had observed the Confederate army in full view and in perfect line, established on a ridge near Sharpsburg. Custer noted that the Rebel battle line was one and a half miles long and that Confederate General Longstreet had forty cannons.
