You will please ascerrge force of the enemy's cavalry had crossed on my right and was moving toward Orleans, and that another force had crossed on my left at Sulphur Springs, and taken pompanies of the First Virginia and two of the First Maryland, I ordered toward Orleans for the purpose of protecting my right flank.
Meanwhile cannonading was kept at White Plains, the advanced guard east of Thoroughfare Gap, and the rear at Orleans.
