Waterloo. General Reynolds is in front of Warrenton. General Bayard is probably over the Rappahannock in the direction of Waterloo. General Pleasonton is probably near Sperryville. Your depot for supplies will be Gainesville until further orders. Supplies from there will be obtained by Centerville and Warrenton turnpike.

I am, general, very respectfully, your obedient servant,

GEO. D. RUGGLES,

Colonel and Assistant chief of Staff.

P. S.-General headquarters will move to-morrow to Warrenton or vicinity. I inclose a sketch of the country for reference to-morrow and next day.

G. D. R.

PP. S.-The general desires me to add that the brigade at Piedmont will follow your command as a rear guard, either by way of Rectortown or by way of Salem, as you may judge best. The route by Salem, however, is deemed preferable. The cavalry of General Burnside, near Manassas Gap, will follow the movement of the entire command, and join General Burnside.

GEO. D. RUGGLES,

Colonel, &c.

Sykes is in, and reports the enemy the same at Snicker's Ferry as heretofore. Scouts followed him a long distnace off. Stragglers are coming in from Harper's Ferry and report a large number there to come up from the Alexandria camp; also wagons.
