I am trying to determine authoritatively the outpost line for the Confederate Army during October 1861. I know that Outpost No. 7 was at the Chantilly House on the Little River Turnpike, but I am most interested in the location of Outpost No. 8. It is supposed to be in the vicinity of a B. F. Cockerille, but a check of the census shows no one by that name in Fairfax County, Virginia. I am hoping that someone has run across some of the other outpost positions that might allow for the reconstruction of the line that might help me identify No. 8. Thank you.
