of the Civil War in America," and perhaps other Military
historians, having assumed and stated--upon the strength of this
passage in Sherman's Report--that "the Military instinct" of that
successful soldier had "discovered" this ford; and the impression
being thus conveyed, however undesignedly, to their readers, that
McDowell's Engineer corps, after spending two or three days in
reconnaissances, had failed to find the ford which Sherman had in a
few minutes "discovered" by "Military instinct;" it is surely due
to the truth of Military history, that the Engineers be fairly
credited with the discovery and mapping of that ford, the existence
of which should also have been known to McDowell's brigade
commanders.

If, on the other hand, the Report of the Rebel Captain Arthur L.
Rogers, of the Loudoun Artillery, to General Philip St. George
Cocke, be correct, it would seem that Sherman attempted to cross
Bull Run lower down than Poplar Ford, which is "about one mile
above the Stone Bridge," but was driven back by the fire of
Rogers's guns to cross at that particular ford; for Rogers, in that
Report, says that about 11 o'clock A. M., the first section of the
Loudoun Artillery, under his command, "proceeded to the crest of
the hill on the West Side of Bull Run, commanding Stone Bridge. *

battery of rifled cannon on the hills opposite. These poured into
my section a steady fire of shot and shell. After giving them some
fifty rounds, I succeeded in heading his column, and turned it up
Bull Run to a ford about one mile above Stone Bridge, where, with
the regiments which followed, they crossed, and proceeded to join
