Fredericksburg. Sunday 14th [September 1862]
We came up yesterday with Dick and Sue.
Our army has crossed the Potomac!! Lee's headquarters are at Frederick city. The joy and enthusiasm of our soldiers at getting into Maryland is beyond description. They crossed near Leesburg, fording waist deep. The Maryland regiments went first singing "Maryland -- My Maryland" and when they reached the other shore the bands struck up Dixie.
