Well both sides had a plan but it did not work out for either side.
General Sickles was to advance to the crossing sites on the Potomac and take them as the Army of Northern Virginia was heading north cutting of southern supplies. The problem was the army never moved north and Sickles was not able to advance very far.
The rest of the Union forces was going to head north to engage the enemy, but instead came on to the map turned left and went after the majority of the southern forces along the Catoctin Mountains.
Now the Army of Northern Virginia was to fight the Army of the Potomac in Maryland but the fight in the mountain valleys was difficult and troops were seperated with General Hood caught in Federick.
Is there a chance for either side to pull out a victory. Possibly but it is too difficult to do a blow by blow. Will have to do a replay I believe. Stay tuned.
