The Peninsula Campaign
> > > Yorktown
General McClellan moved the Army of Potomac to Fort Monroe. From there, his plan called for a rapid movement up the Peninsula, past the Confederate positions at Yorktown, and then on Towards Richmond– All this before sufficient Confederate reinforcements could arrive. McClellan however, undertook a seige of the fortress at Yorktown. The sige took one month. As the Union forces were ready to attack, the Confederates pulled out.
