he could muster barely 18,000 men and 29 guns.
In view of this supposed disparity of opposing force, Beauregard
urged President Davis
to concentrate the armies of Johnston
with his at Manassas
, that he might be ready to fall upon McDowell
's flanks, rear, and line of communication, whenever he should advance, cut off his retreat upon Washington
, and force him to surrender; and, by so doing, compel Patterson
to retreat from the lower Shenandoah valley, and thus insure the capture of Washington
These suggestions were not favorably received at Richmond

, where the turnpikes from the valley through Snicker's gap and Ashby
