Operation Golgotha Inebreate
General McClellan found General Lee's battle plan.
The orders showed the plan for Lees Maryland Campaign and led to the Battle of Antietam.
Unlike General George B. McClellan's frequent communications to Washington DC during the Peninsula campaign, McClellan was relatively silent concerning his plans for fighting the Confederates in Maryland and the Battle of Antietam. His immediate superior officer, General in Chief Henry W. Halleck was no notified of McClellan's intentions. It appears that all of his orders to his generals were mostly verbal and records of his side of the encounter at Antietam were sparse.
After the Battle of Antietam in September of 1862, Lee's Army of Northern Virginia had to retreat from Maryland back to Virginia. Lee's evacuation from Maryland, for that moment of the war ended Confederate plans to take the war to the enemy, the Union.
the Anaconda Plan
The name was "The Anaconda Plan". It was a strategic plan set up by Union General Winfield Scott
The Anaconda plan
A set of Lee's orders that a Confederate officer had accidentally dropped in the field. They showed that Lee's divisions were widely separated, and that McClellan could destroy them piecemeal.
"The Schlieffen Plan". Named for the general commanding the Imperial German Army when the plan was developed, a generation before WWI.the schlieffen plan
Confederate General Robert E. Lee knew he was clearly outnumbered as the Battle of Antietam was about to begin. To compensate for the large disparity in troop strength. Lee decided to use the battle tactic of tactical defense. With the understanding that he could not mount any kind of offensive and being clear that the Army of the Potomac, led by General George B. McClellan, a well planned defense was Lee's best alternative to escape losing his army.
Winfield Scott, whose picture is above, created a plan that became known as the "Anaconda Plan".
After the Battle of Antietam and the Confederate retreat back to Virginia, General McClellan proposed a plan of action that appears to be a logical one from a military and political point of view. He proposed to prevent more Southern raids into the North by securing a line along the Potomac River and along the Shenandoah Valley. This plan was ambitious and required extensive bridge building and railroad constructions that would be fortified to protect them. He also saw the prospect of renewing his peninsula campaign in 1863 as the plans to secure the Potomac and the Shenandoah Valley would have protected Washington DC.
