The Situation on 11 September: During the second day out of Frederick, three Confederate columns are on the way to their assigned positions around Harpers Ferry: Jackson takes a longer route than planned, crosses the Potomac at WIlliamsport, and ends the day north and west of Martinsburg; McLaws enters Pleasant Valley; and Walker spends the day resting across the Potomac from Point of Rocks.

DH Hill's Division marches out of Frederick on the 11th and camps just west of Middletown. Gen Lee accompanies the remaining units of Longstreet's Command to near Hagerstown.

General Stuart's Cavalry pull back to positions behind the Monocacy: Munford above Urbana, Hampton in Frederick, and Fitz Lee, after a gallop to Liberty, just west of the river, north of town.

Ahead of McClellan's Army of the Potomac, Federal Cavalry is pushing toward Frederick. They cross Sugar Loaf Mountain, occupy Urbana, and advance beyond New Market on the National Road.

The Union Infantry pushes forward on left and right, moving on Frederick while keeping both Baltimore and Washington covered. On the left, Couch's Division moves up to Poolesville, and Franklin's VI Corps ends the day at Barnesville. Burnside's right wing advances north and west to hit the National Road east of New Market.
