When Union General George B. McClellan received Lee's Special Order No. 191, he was certain that he now had the means to defeat Lee's army. In communications with General Halleck, McClellan declared he would win a decisive victory over Lee's forces. At the time, it was interpreted to mean a huge victory over the Army of Northern Virginia. Historians believe that to McClellan, anything that caused Lee to retreat from Maryland would be "decisive". Some of confusion was the result of McClellan's reference to one of Napoleon's great victories.
The 1862, the Battle of Antietam was fought in Maryland. The Army of Northern Virginia fought against the Army of the Potomac. It was Lee versus McClellan.
Upon learning of the raid into Maryland by General Lee and his Army of Northern Virginia, Major General George B. McClellan knew he was facing a challenge from the South's best general and its best army. With that in mind, McClellan began to follow the Confederates slowly, making sure that Washington DC and Baltimore, Maryland were secure. He also needed time to reorganize his Army of the Potomac in order to meet Lee's challenge.

AnswerLee 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.Niomieshon
