Lee, showing his understanding of the serious threat posed by Union naval operations on the rivers, reported that: "six batteries have been erected on the Elizabeth River, to guard the approaches to Norfolk and the Navy Yard...to prevent ascent of the Nansemond River and the occupation of the railroad from Norfolk to Richmond, three batteries have been constructed...
"Sites for batteries on the Potomac have also been selected, and arrangements were in progress for their construction, but the entire command of that river being in possession of the U.S. Government, a larger force is required for their security than could be devoted to that purpose.
"The batteries at Aquia Creek have only been prepared... On the Rappahannock River a 4-gun battery... has been erected."
