It appears as if the Union has decided to invade Virginia, when they saw our movements to the West. Of course, in real life they followed Lee's army to the North, and tried to stay between the Confereates and Washington and Baltimore. No such conern in this game.
So, based on these event's the movements for July are as follows.
Stuart's Corps will proceed to Harrisburg.
Lee with Longstreet's Corps will advance to Baltimore and attack immediately upon arrival.
Ewell with Hill's Corps will advance to Washington and begin a seige.
