--Advices received from passengers by the Central
train confirm the report which we mentioned yesterday, that the enemy were falling back, and that all their force had been withdrawn from the south side of the Rappahannock
Their cavalry is picketing at Orleans
, points in Fauquier county
, whilst their infantry is further north, along the line of the Orange and Alexandria Railroad.
Deserters represent that their force has been considerably reduced by details to go North to assist in the execution of the draft.
