Lee had invaded Maryland hoping to score a decisive victory, on Northern soil, against the Army of the Potomac and gain a strategic advantage. McClellan, again commanding the Northern army, discovered Lee's movements and that his army was divided. McClellan hoped to attack and destroy the separate pieces of Lee's army individually. But he moved too slowly and Lee was able to reunite his scattered forces. So, by the time they met at Antietam Creek, McClellan was still hoping to destroy Lee but Lee was just hoping for a defensive victory that he might turn to his advantage. Neither of them got what they wanted.

He succeeded in repealing Lee offensive making the Confederate Army to retreat from Maryland.
Major General George B. McClellan no longer used Allan Pinkerton as a source of military intelligence as he approached what would become the Battle of Antietam. His men had found a good source in the so-called lost order of General Lee that described Lee's battle plans. With that said, he made good use of the cavalry of General Pleasanton and received information from friendly civilians.
After Antietam (Sept 17, 1862) when McClellan once again believed he needed time for his troops to rest. President Lincoln replaced him (on Nov 7) with General Ambrose Burnside. That was the end of McClellan's service as a Union military leader. As an aside, General Burnside felt uncomfortable replacing George B. McClellan. He had been loyal to him, also, he was not sure the command of the Army of the Potomac would be a fit for his abilities.
After the battle of Antietam, Lincoln decided to replace General McClellan as the top military commander with general Ambrose E. Burnside. On November 3rd of 1862, Lincoln made this important change in the Union's military forces.
In pure military assessments of the Battle of Antietam, military historians see the battle as being one of inconclusive results. When military experts sweep away all the political ramifications of that battle, they see an inept and numerically superior Union army, Yes, Lee had to retreat, in fact no matter what happened in Sharpsburg, Lee did not have enough men or supplies to stay in Maryland. Military minded people say that Lee's other objectives were met, thereby, in a sense, nullify the results at Antietam. Militarists point out that Lee's invasion prevented a combined effort by McClellan and General John Pope to advance on Richmond. Lee's positions before and after Antietam transferred all military operations to northern Virginia. Based on Southern newspapers, the Southern public was not discouraged by the setback in Maryland. Also, the Army of Northern Virginia remained a force that within seven weeks doubled its size.With all the above said, Antietam was a political victory for Lincoln and the Union. Lincoln was then resolved to release his first emancipation proclamation.
The battle of Antietam.
Clearly the so-called Maryland campaign was the climax of Major General George B. McClellan's military career and the Battle of Antietam his greatest and most important battle. The Battle of Antietam is legendary as the bloodiest day in US military history with over 25,000 casualties in one day which includes both sides of the battle.
As the Battle of Antietam approached General George B. McClellan received military intelligence on the Army of Northern Virginia from three sources. One was his cavalry general Alfred Pleasonton, also from Allan Pinkerton and Maryland civilians loyal to the Union.

Based on military criteria, the Battle of Antietam was a draw. This is an important military term for the actual results of that battle. It's true that General Lee retreated to Virginia, however, this was a raid and there was no intention of occupying Maryland.
A military base was attacked.
Sharpsburg was the nearest town, and that was how the Confederates preferred to name their battles. The fighting occurred beside Antietam Creek, the spot where Lee had to concentrate his scattered divisions in a hurry, after a set of his orders had accidentally fallen into the hands of the Union commander McClellan. Although this was the Northern win that Lincoln had been waiting for (to give him the credibility to issue the Emancipation Proclamation), he was losing his patience with McClellan who had failed to exploit his opportunity to destroy Lee's army, and allowed it to get safely back to Virginia. A few weeks later, McClellan's military career was over, and he would be running against Lincoln in the 1864 General Election.

After the 1862 Battle of Antietam, both sides of the battle needed rest. General Lee retreated back into Virginia, as although the result of the battle was, in military terms a draw. Lee, however, had no choice but to return to Virginia. For nearly six weeks after Antietam, Major General George B. McClellan remained encamped north of the Potomac River. President Lincoln became impatient with McClellan and urged him to pursue the Confederates across the Potomac and inflict more damage to Lee's crippled army. After Lincoln's visit to McClellan's campsite, Confederate cavalry commander JEB Stuart led a force of 1,800 cavalrymen on a raid into Chambersburg Pennsylvania and encircled a Federal army there. President Lincoln was extremely disturbed that McClellan could not cross the Potomac when it was clear that the Confederates could and did. This incident was another reason for the eventual firing of McClellan by President Lincoln.
The private organization that Union General George McClellan hired to help gather military intelligence was the Union Espionage Organization.
