All the Army of McDowell, save his Left Wing--which, comprising the two
brigades (Blenker's and Davies's) of Miles's Division, and Richardson's
Brigade of Tyler's Division that fought the preliminary battle of
Blackburn's Ford, is now under the command of Miles,--moved away from
Centreville, down the Warrenton Pike, as we have seen, very early in the
morning.

Blenker remains with his brigade as a reserve, on the heights a little
East of Centreville, to throw up intrenchments; which, however, he does

upon the left flank and rear of the Enemy's Bull Run line.

Richardson's Brigade is already down the ridge, in his old position at
Blackburn's Ford, when Davies with his brigade reaches it, from
Centreville, and, by virtue of seniority, takes command of the two
brigades. Leaving Richardson's Brigade and Greene's Battery exactly on
the battle-ground of the 18th July, Davies posts two regiments (the 18th
and 32nd New York) of his own brigade, with Hunt's Battery, on the brow
of a hill, in an open wheat field, some eighty yards to the
South-Eastward of Richardson, distant some 1,500 yards from Longstreet's
batteries on the Western side of Bull Run,--and commences a rapid fire,
upon the Enemy's position at Blackburn's Ford, from both of the Union
batteries.

At 10 o'clock, there is a lull in this Union fire. The Artillery
ammunition is running short. The demonstration, however, seems, thus
